Accounting Policies [Abstract]
Basis of Presentation and New Accounting Standards	Basis of Presentation and New Accounting Standards Overview Cree, Inc. (the Company) is an innovator of wide bandgap semiconductors, focused on silicon carbide and gallium nitride materials, products for power and radio-frequency (RF) applications and specialty lighting-class light emitting diode (LED) products. The Company's silicon carbide and gallium nitride materials and products are targeted for applications such as transportation, power supplies, inverters, wireless systems, and the Company's LEDs are targeted for indoor and outdoor lighting, electronic signs and signals and video displays. The Company operates in two reportable segments: • Wolfspeed , which consists of silicon carbide and gallium nitride (GaN) materials, power devices and RF devices based on wide bandgap semiconductor materials and silicon. The Company's materials products and power devices are used in electric vehicles, motor drives, power supplies, solar and transportation applications. The Company's materials products and RF devices are used in military communications, radar, satellite and telecommunication applications. • LED Products , which consists of LED chips and LED components. The Company's LED products enable its customers to develop and market LED-based products for lighting, video screens, automotive and specialty lighting applications. Previously, the Company designed, manufactured and sold LED lighting fixtures and lamps for the commercial, industrial and consumer markets. The Company referred to these product lines as the Lighting Products business unit. As discussed in Note 2 , “Discontinued Operations,” on May 13, 2019, the Company sold its Lighting Products business unit to IDEAL Industries, Inc. (IDEAL). Unless otherwise noted, discussion within these notes to the consolidated financial statements relates to the Company's continuing operations. The majority of the Company's products are manufactured at its production facilities located in North Carolina, California, Arkansas and China. The Company also uses contract manufacturers for certain products and aspects of product fabrication, assembly and packaging. The Company operates research and development facilities in North Carolina, Arizona, Arkansas, California and China (including Hong Kong). Cree, Inc. is a North Carolina corporation established in 1987, and its headquarters are in Durham, North Carolina. Basis of Presentation The consolidated financial statements presented herein have been prepared by the Company and have not been audited. In the opinion of management, all normal and recurring adjustments necessary to fairly state the consolidated financial position, results of operations, comprehensive loss, shareholders' equity and cash flows at September 29, 2019 , and for all periods presented, have been made. All material intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 30, 2019 has been derived from the audited financial statements as of that date. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2019 (fiscal 2019 ). The results of operations for the three months ended September 29, 2019 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 28, 2020 (fiscal 2020 ). Historical periods presented include reclassifications to reflect discontinued operations (see Note 2, "Discontinued Operations"). The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities. Actual amounts could differ materially from those estimates. The Company revised net cash provided by operating activities and net cash provided by financing activities for the three months ended September 23, 2018 to correct the presentation of tax withholding for stock option exercises. The Company increased net cash provided by operating activities by $10.8 million and decreased net cash provided by financing activities by the same amount. The Company will also revise the unaudited consolidated statements of cash flows for the year to date periods ended December 30, 2018 and March 31, 2019 in the unaudited interim consolidated financial statements to be filed in the Quarterly Reports on Form 10-Q for the corresponding periods in fiscal 2020 to correct the presentation of tax withholding for stock option exercises. The revisions will result in an increase to net cash provided by operating activities of $11.9 million and $12.4 million , and a decrease to net cash provided by financing activities by the same amounts for the year to date periods ended December 30, 2018 and March 31, 2019, respectively. The Company concluded these errors were not material individually or in the aggregate to any of the periods impacted. Certain prior period amounts related to the Lighting Products business unit in the accompanying statements of cash flows have been reclassified to conform to the current year presentation. These reclassifications pertain to the presentation of discontinued operations within operating, investing and financing activities. This reclassification did not impact cash provided by (used in) operating, investing, or financing activities. Recently Adopted Accounting Pronouncements Leases In February 2016, the FASB issued ASU No. 2016-02: Leases (Topic 842) (ASC 842), and ASU 2018-10: Codification Improvements to ASC 842, Leases. These ASUs require that a lessee recognize in its statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term and requires enhanced disclosures about an entity’s leasing arrangements. The Company adopted this standard on July 1, 2019, under the modified retrospective transition approach with the cumulative effect of application recognized at the effective date, without adjustment to prior comparative periods. The Company elected to utilize the transition package of practical expedients that allows the Company to not reassess (1) whether any expired or existing contracts are leases, or contain leases, (2) the lease classification for any expired or existing leases, and (3) initial direct costs for any existing leases. Further, the Company elected the practical expedient to not separate lease and non-lease components for all leases and account for the combined lease and non-lease components as a single lease component. The Company also made an accounting policy election to exclude leases with an initial term of 12 months or less from the consolidated balance sheets. The adoption of the new standard resulted in the recognition of $12.2 million of lease liabilities with corresponding right-of-use assets of $12.3 million as of July 1, 2019. As required, the right-of-use assets include the effect of reclassifying certain balances including deferred and prepaid rent, a portion of facilities-related restructuring accrual reserves, and a favorable lease intangible asset previously recognized in connection with an acquisition. The Company did not have a cumulative-effect adjustment to retained earnings as a result of the adoption of the new standard. The standard did not materially impact the Company's results from operations and had no impact on cash flows. See Note 4 , "Leases," for additional disclosures, as required by the new standard. The reported results as of and for the three months ended September 29, 2019 reflect the application of the new accounting guidance, while the reported results for prior periods have not been adjusted and continue to be reported in accordance with the Company's historical accounting under ASC 840, Leases. Accounting Pronouncements Pending Adoption Credit Losses In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU introduces a new accounting model known as Credit Expected Credit Losses (“CECL”). CECL requires earlier recognition of credit losses, while also providing additional transparency about credit risk. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for receivables at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. This model replaces the multiple existing impairment models in current GAAP, which generally require that a loss be incurred before it is recognized. The new standard will also apply to receivables arising from revenue transactions such as contract assets and accounts receivables. There are other provisions within the standard affecting how impairments of other financial assets may be recorded and presented, as well as expanded disclosures. The Company will adopt this standard on June 29, 2020 and is currently evaluating the impact on its consolidated financial statements.

Discontinued Operations	Discontinued Operations On May 13, 2019, the Company completed the sale of (a) certain manufacturing facilities and equipment, inventory, intellectual property rights, contracts, and real estate of the Company used by the Company's Lighting Products business unit, which includes LED lighting fixtures, lamps and corporate lighting solutions for commercial, industrial and consumer applications, and (b) all of the issued and outstanding equity interests of E-conolight LLC (E-conolight), Cree Canada Corp. and Cree Europe S.r.l., each a wholly owned subsidiary of the Company (collectively, the Lighting Products business unit) to IDEAL, pursuant to the Purchase Agreement, dated March 14, 2019, as amended, between the Company and IDEAL (the Purchase Agreement). The Company retained certain liabilities associated with the Lighting Products business unit arising prior to the closing of the sale. The Lighting Products business unit represented the Lighting Products segment disclosed in the Company's historical financial statements. The aggregate net proceeds from the sale of the Lighting Products business unit was $219.0 million in cash, which is subject to certain adjustments. Additionally, the Company is entitled to an earnout payment subject to the future performance of the Lighting Products business unit. In connection with the transaction, the Company and IDEAL entered into certain ancillary and related agreements, including (i) an Intellectual Property Assignment and License Agreement, which assigned to IDEAL certain intellectual property owned by the Company and licensed to IDEAL certain additional intellectual property owned by the Company; (ii) a Transition Services Agreement (the TSA), which is designed to ensure a smooth transition of the Lighting Products business unit to IDEAL; (iii) an LED Supply Agreement (the LED Supply Agreement), pursuant to which the Company will supply IDEAL with certain LED chip and component products for three years; and (iv) a Real Estate License Agreement, which will allow IDEAL to use certain premises owned by the Company to conduct certain operations of the Lighting Products business unit after closing. The Company recognized a loss on the sale of $66.2 million . The Company has classified the results of the Lighting Products business unit as discontinued operations, the results of which for the three months ended September 23, 2018 are as follows: Three months ended (in millions of U.S. Dollars) September 23, 2018 Revenue, net $134.1 Cost of revenue, net 104.2 Gross profit 29.9 Operating expenses: Research and development 9.7 Sales, general and administrative 23.8 Amortization or impairment of acquisition-related intangibles 4.6 Loss on disposal or impairment of long-lived assets 0.1 Other operating expense 1.9 Operating loss (10.2 ) Non-operating income (0.2 ) Loss before income taxes (10.0 ) Income tax expense 0.3 Net loss ($10.3 ) The Company did not have any discontinued operations activity for the three months ended September 29, 2019 . The Company recognized $3.0 million in administrative fees for the three months ended September 29, 2019 relating to the TSA, of which $0.9 million are included in accounts receivable, net in the consolidated balance sheets as of September 29, 2019 . These fees were recorded as a reduction of sales, general and administrative expense in the consolidated statements of operations. The Company recognized $2.9 million in revenue for the three months ended September 29, 2019 related to the LED Supply Agreement. No amounts were included in accounts receivable, net in the consolidated balance sheets as of September 29, 2019 relating to the LED Supply Agreement.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition In accordance with ASC 606, the Company follows a five-step approach defined by the new standard for recognizing revenue, consisting of the following: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. Contract liabilities primarily include various rights of return and customer deposits, as well as deferred revenue, price protection guarantees and the Company's liability under the LED Supply Agreement. Contract liabilities were $87.6 million as of September 29, 2019 and $80.4 million as of June 30, 2019 , the date the Company adopted ASC 606. The increase was primarily due to increased customer deposits. Contract liabilities are recorded within accrued contract liabilities and other long-term liabilities on the balance sheet. Before the adoption of ASC 606, liabilities relating to various rights of return were recorded as a deduction to accounts receivable. Disaggregated revenue by geography is presented in Note 14, "Reportable Segments". For the three months ended September 29, 2019 , the Company recognized revenue of $1.0 million that was included in contract liabilities as of June 30, 2019 . The amount recognized primarily related to the recognition of contingent liabilities related to the LED Supply Agreement and deferred revenue. Revenue recognized related to performance obligations that were satisfied or partially satisfied in previous periods was not material for the three months ended September 29, 2019 .

Leases

Leases	3 Months Ended

Leases [Abstract]
Leases	Leases The Company primarily leases manufacturing, office and warehousing space. Lease agreements frequently include renewal provisions and require the Company to pay real estate taxes, insurance and maintenance costs. Variable costs include lease payments that were volume or usage-driven in accordance with the use of the underlying asset, as well as non-lease components incurred with respect to actual terms rather than contractually fixed amounts. The Company does not have any finance lease arrangements. Accounting Policy At lease inception, the Company determines a contract contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. In evaluating whether it has the right to control the use of an identified asset, the Company assesses whether they have the right to direct the use of the identified asset and to obtain substantially all of the economic benefit from the use of the identified asset. Right-of-use assets represent the Company's right to use an underlying asset during the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Assets and liabilities are recognized based on the present value of lease payments over the lease term. Most leases include one or more options to renew, with renewal terms that can extend the lease term from one to five years or more. The exercise of the renewal option is at the Company's sole discretion and the Company considers these options in determining the lease term used to establish its right-of-use assets and lease liabilities. Because most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. The Company uses the implicit rate when readily determinable. Operating lease expense is generally recognized on a straight-line basis over the lease term. The Company has agreements with lease and non-lease components, which are accounted for as a single lease component. Leases with a lease term of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. Variable lease payment amounts that cannot be determined at the commencement of the lease, such as increases in lease payments based on changes in index rates, are not included in the right-of-use assets or liabilities. These variable lease payments are expensed as incurred. Balance Sheet Lease assets and liabilities as of September 29, 2019 , and the corresponding balance sheet classifications, are as follows (in millions of U.S. Dollars): Category Balance Sheet Classification Amount Right-of-use asset Other assets $11.4 Current lease liability Other current liabilities 5.3 Non-current lease liability Other long-term liabilities 6.0 Statement of Operations Operating lease expense was $1.4 million for three months ended September 29, 2019 .

If incurred, realized losses are included in non-operating expense in the consolidated statements of operations. Unrealized gains and losses are included as a separate component of equity, net of tax, unless the loss is determined to be other-than-temporary. The Company evaluates its investments for possible impairment or a decline in fair value below cost basis that is deemed to be other-than-temporary on a periodic basis. It considers such factors as the length of time and extent to which the fair value has been below the cost basis, the financial condition of the investee, and its ability and intent to hold the investment for a period of time that may be sufficient for an anticipated full recovery in market value.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the exit price) in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various valuation approaches, including quoted market prices and discounted cash flows. U.S. GAAP also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are obtained from independent sources and can be validated by a third party, whereas unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability. The fair value hierarchy is categorized into three levels based on the reliability of inputs as follows: • Level 1 - Valuations based on quoted prices in active markets for identical instruments that the Company is able to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. • Level 2 - Valuations based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. • Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The financial assets for which the Company performs recurring fair value remeasurements are cash equivalents, short-term investments and long-term investments. As of September 29, 2019 and June 30, 2019 , financial assets utilizing Level 1 inputs included money market funds and U.S. treasury securities. Financial assets utilizing Level 2 inputs included municipal bonds, corporate bonds, certificates of deposit, commercial paper, U.S. agency securities, variable rate demand notes and common stock of non-U.S. corporations. Level 2 assets are valued based on quoted prices in active markets for instruments that are similar or using a third-party pricing service’s consensus price, which is a weighted average price based on multiple sources. These sources determine prices utilizing market income models which factor in, where applicable, transactions of similar assets in active markets, transactions of identical assets in infrequent markets, interest rates, bond or credit default swap spreads and volatility. The Company did not have any financial assets requiring the use of Level 3 inputs as of September 29, 2019 and June 30, 2019 .

Debt Disclosure [Abstract]
Long-term Debt	Long-term Debt Revolving Line of Credit As of September 29, 2019 , the Company had a $500.0 million secured revolving line of credit (the "Credit Agreement") under which the Company can borrow, repay and reborrow loans from time to time prior to its scheduled maturity date of January 9, 2022. The Company classifies balances outstanding under its line of credit as long-term debt in the consolidated balance sheets. As of September 29, 2019 , the Company had no thing outstanding under the Credit Agreement, $500.0 million in available commitments under the Credit Agreement and $325.4 million available for borrowing. For the three months ended September 29, 2019 , the average interest rate was 0.00% and the average commitment fee percentage was 0.05% . The Company was in compliance with all covenants under the Credit Agreement at September 29, 2019 . Convertible Notes On August 24, 2018, the Company sold $500.0 million aggregate principal amount of 0.875% convertible senior notes due September 1, 2023 to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended, and an additional $75.0 million aggregate principal amount of such notes pursuant to the exercise in full of the over-allotment options of the underwriters (the Notes). The total net proceeds from the debt offering was approximately $562.1 million . The conversion rate will initially be 16.6745 shares of common stock per one thousand dollars in principal amount of Notes (equivalent to an initial conversion price of approximately $59.97 per share of common stock). The conversion rate will be subject to adjustment for some events, but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, or following the Company's issuance of a notice of redemption, the Company will increase the conversion rate for a holder who elects to convert its Notes in connection with such a corporate event, or who elects to convert any Notes called for redemption during the related redemption period in certain circumstances. The Company may not redeem the Notes prior to September 1, 2021. The Company may redeem for cash all or any portion of the Notes, at its option, on a redemption date occurring on or after September 1, 2021 and on or before the 40th scheduled trading day immediately before the maturity date, if the last reported sales price of its common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides a notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption. The redemption price will be 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. If the Company undergoes certain fundamental changes related to the Company's common stock, holders may require the Company to repurchase for cash all or any portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. Holders may convert their Notes at their option at any time prior to the close of business on the business day immediately preceding March 1, 2023 only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending December 31, 2018 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period in which the trading price per one thousand dollars in principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of its common stock and the conversion rate on each such trading day; (3) if the Company calls such Notes for redemption, at any time prior to the close of business on the second business day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after March 1, 2023 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver cash, shares of its common stock, or a combination of cash and shares of its common stock, at the Company's election. In accounting for the issuance of the convertible senior notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability of the equity component representing the conversion option was $110.6 million and was determined by deducting the fair value of the liability component from the par value of the Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount (the debt discount), along with related issuance fees are amortized to interest expense over the term of the Notes at an effective interest rate of 0.49% . The net carrying amount of the liability component of the Notes is as follows: (in millions of U.S. Dollars) September 29, 2019 June 30, 2019 Principal $575.0 $575.0 Unamortized discount and issuance costs (100.3 ) (105.9 ) Net carrying amount $474.7 $469.1 The net carrying amount of the equity component of the Notes is as follows: (in millions of U.S. Dollars) September 29, 2019 June 30, 2019 Discount related to value of conversion option $113.3 $113.3 Debt issuance costs (2.7 ) (2.7 ) Net carrying amount $110.6 $110.6 The interest expense recognized related to the Notes is as follows: Three months ended (in millions of U.S. Dollars) September 29, 2019 September 23, 2018 Interest expense $1.3 $0.4 Amortization of discount and issuance costs 5.6 1.8 Total interest expense $6.9 $2.2 The estimated fair value of the Notes is $631.4 million as of September 29, 2019 , as determined by a Level 2 valuation.

For the three months ended September 29, 2019 and September 23, 2018 , 5.9 million and 10.1 million of weighted average shares were excluded from the calculation of diluted loss per share because their effect would be anti-dilutive. Future earnings per share of the Company are also subject to dilution from conversion of its convertible notes under certain conditions as described in Note 9, “Long-term Debt.”

Stock-Based Compensation

Stock-Based Compensation	3 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Overview of Employee Stock-Based Compensation Plans The Company currently has one equity-based compensation plan, the 2013 Long-Term Incentive Compensation Plan (2013 LTIP), from which stock-based compensation awards can be granted to employees and directors. The 2013 LTIP provides for awards in the form of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other awards. The Company has other equity-based compensation plans that have been terminated so that no future grants can be made under those plans, but under which stock options, restricted stock and restricted stock units are currently outstanding. The Company’s stock-based awards can be either service-based or performance-based. Performance-based conditions are generally tied to future financial and/or operating performance of the Company and/or external based market metrics. The compensation expense with respect to performance-based grants is recognized if the Company believes it is probable that the performance condition will be achieved. The Company reassesses the probability of the achievement of the performance condition at each reporting period, and adjusts the compensation expense for subsequent changes in the estimate or actual outcome. As with non-performance based awards, compensation expense is recognized over the vesting period. For performance awards with market conditions, the Company estimates the grant date fair using the Monte Carlo valuation model and expenses the awards over the vesting period regardless of whether the market condition is ultimately satisfied. The Company also has an Employee Stock Purchase Plan (ESPP) that provides employees with the opportunity to purchase common stock at a discount. The ESPP limits employee contributions to 15% of each employee’s compensation (as defined in the plan) and allows employees to purchase shares at a 15% discount to the fair market value of common stock on the purchase date two times per year. The ESPP provides for a twelve-month participation period, divided into two equal six-month purchase periods, and also provides for a look-back feature. At the end of each six-month period in April and October, participants purchase the Company’s common stock through the ESPP at a 15% discount to the fair market value of the common stock on the first day of the twelve-month participation period or the purchase date, whichever is lower. The plan also provides for an automatic reset feature to start participants on a new twelve-month participation period if the fair market value of common stock declines during the first six-month purchase period. Stock Option Awards The following table summarizes stock option awards outstanding as of September 29, 2019 and changes during the three months then ended: (shares in thousands) Number of Shares Weighted Average Exercise Price Outstanding at June 30, 2019 2,418 $39.81 Granted — $— Exercised (494 ) $37.25 Forfeited or expired (23 ) $49.85 Outstanding at September 29, 2019 1,901 $40.36 Restricted Stock Awards and Units A summary of nonvested restricted stock awards (RSAs) and restricted stock unit awards (RSUs) outstanding as of September 29, 2019 , and changes during the three months then ended is as follows: (awards and units in thousands) Number of RSAs/RSUs Weighted Average Grant-Date Fair Value Nonvested at June 30, 2019 3,081 $34.99 Granted 972 $57.86 Vested (959 ) $30.22 Forfeited (43 ) $33.43 Nonvested at September 29, 2019 3,051 $44.00 Stock-Based Compensation Valuation and Expense The Company accounts for its employee stock-based compensation plans using the fair value method. The fair value method requires the Company to estimate the grant-date fair value of its stock-based awards and amortize this fair value to compensation expense over the requisite service period or vesting term. The Company uses the Black-Scholes option-pricing model to estimate the fair value of the Company’s stock option and ESPP awards. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include the expected stock price volatility over the term of the awards, projected employee stock option exercise term, the risk-free interest rate and expected dividends. Due to the inherent limitations of option-valuation models, future events that are unpredictable and the estimation process utilized in determining the valuation of the stock-based awards, the ultimate value realized by award holders may vary significantly from the amounts expensed in the Company’s financial statements. For RSAs and RSUs, the grant-date fair value is based upon the market price of the Company’s common stock on the date of the grant. This fair value is then amortized to compensation expense over the requisite service period or vesting term. Stock-based compensation expense is recognized net of estimated forfeitures such that expense is recognized only for those stock-based awards that are expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. Total stock-based compensation expense was classified in the consolidated statements of operations as follows: Three months ended (in millions of U.S. Dollars) September 29, 2019 September 23, 2018 Cost of revenue, net $2.2 $1.6 Research and development 2.4 1.5 Sales, general and administrative 12.3 6.9 Total stock-based compensation expense $16.9 $10.0 An additional $0.5 million of stock-based compensation was capitalized into inventory for the three months ended September 29, 2019 . Less than $0.1 million of stock-based compensation was capitalized into inventory for the three months ended September 23, 2018 .

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In general, the variation between the Company's effective income tax rate and the U.S. statutory rate of 21% is primarily due to: (i) changes in the Company’s valuation allowances against deferred tax assets in the U.S. and Luxembourg, (ii) projected income for the full year derived from international locations with lower tax rates than the U.S. and (iii) projected tax credits generated. The Company assesses all available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets by jurisdiction. The Company has concluded that it is necessary to recognize a full valuation allowance against its U.S. and Luxembourg deferred tax assets, as of the three months ended September 29, 2019 . As of June 30, 2019 , the U.S. valuation allowance was $177.6 million . During the three months ended September 29, 2019 , the Company did not record any material movement in its U.S. valuation allowance. As of June 30, 2019 , the Luxembourg valuation allowance was $7.6 million . During the three months ended September 29, 2019 , the Company decreased this valuation allowance by $0.8 million due to year-to-date income in Luxembourg. U.S. GAAP requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is cumulatively more than 50% likely to be realized upon ultimate settlement. As of June 30, 2019 , the Company's liability for unrecognized tax benefits was $8.2 million . During the three months ended September 29, 2019 , the Company did not record any material movement in its unrecognized tax benefits. As a result, the total liability for unrecognized tax benefits as of September 29, 2019 was $8.2 million . If any portion of this $8.2 million is recognized, the Company will then include that portion in the computation of its effective tax rate. Although the ultimate timing of the resolution and/or closure of audits is highly uncertain, the Company believes it is reasonably possible that $1.0 million of gross unrecognized tax benefits will change in the next 12 months as a result of statute requirements or settlement with tax authorities. The Company files U.S. federal, U.S. state and foreign tax returns. For U.S. federal purposes, the Company is generally no longer subject to tax examinations for fiscal years prior to 2016. For U.S. state tax returns, the Company is generally no longer subject to tax examinations for fiscal years prior to 2015. For foreign purposes, the Company is generally no longer subject to examination for tax periods prior to 2009. Certain carryforward tax attributes generated in prior years remain subject to examination, adjustment and recapture.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation The Company is currently a party to various legal proceedings. While management presently believes that the ultimate outcome of such proceedings, individually and in the aggregate, will not materially harm the Company’s financial position, cash flows, or overall trends in results of operations, legal proceedings are subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages or, in matters for which injunctive relief or other conduct remedies may be sought, an injunction prohibiting the Company from selling one or more products at all or in particular ways. Were unfavorable final outcomes to occur, there exists the possibility of a material adverse impact on the Company’s business, results of operations, financial position and overall trends. The outcomes in these matters are not reasonably estimable.

Segment Reporting [Abstract]
Reportable Segments	Reportable Segments Reportable segments are components of the Company that the Chief Operating Decision Maker (CODM) regularly reviews when allocating resources and assessing performance. The Company’s CODM reviews segment performance and allocates resources based upon segment revenue and segment gross profit. The Company's identified CODM is the Chief Executive Officer. The Company’s operating and reportable segments are: • Wolfspeed • LED Products The Wolfspeed segment includes silicon carbide materials, power devices and RF devices and the LED Products segment includes LED chips and LED components. Financial Results by Reportable Segment The tables below reflect the results of the Company's reportable segments as reviewed by the CODM for the three months ended September 29, 2019 and September 23, 2018 . The Company used the same accounting policies to derive the segment results reported below as those used in the Company’s consolidated financial statements. The Company’s CODM does not review inter-segment transactions when evaluating segment performance and allocating resources to each segment, and inter-segment transactions are not included in the segment revenue presented in the table below. As such, total segment revenue in the table below is equal to the Company’s consolidated revenue. The Company’s CODM reviews gross profit as the lowest and only level of segment profit. As such, all items below gross profit in the consolidated statements of operations must be included to reconcile the consolidated gross profit presented in the table below to the Company’s consolidated loss before income taxes. In order to determine gross profit for each reportable segment, the Company allocates direct costs and indirect costs to each segment’s cost of revenue. The Company allocates indirect costs, such as employee benefits for manufacturing employees, shared facilities services, information technology, purchasing, and customer service, when the costs are identifiable and beneficial to the reportable segment. The Company allocates these indirect costs based on a reasonable measure of utilization that considers the specific facts and circumstances of the costs being allocated. Unallocated costs in the table below consisted primarily of manufacturing employees’ stock-based compensation, expenses for profit sharing and quarterly or annual incentive plans, and matching contributions under the Company’s 401(k) plan. These costs were not allocated to the reportable segments' gross profit because the Company’s CODM does not review them regularly when evaluating segment performance and allocating resources. The cost of goods sold (COGS) acquisition related cost adjustment includes acquisition costs related to our acquisition of the RF Power (RF Power) business of Infineon Technologies AG (Infineon) impacting cost of revenue for fiscal 2019. These costs were not allocated to the reportable segments' gross profit for fiscal 2019 because they represent an adjustment which does not provide comparability to the corresponding prior period and therefore were not reviewed by the Company's CODM when evaluating segment performance and allocating resources. Revenue, gross profit and gross margin for each of the Company's segments were as follows: Three months ended September 29, 2019 September 23, 2018 Revenue: Wolfspeed revenue $127.7 $127.4 LED Products revenue 115.1 146.8 Total revenue $242.8 $274.2 Gross Profit and Gross Margin: Wolfspeed gross profit $59.0 $60.4 Wolfspeed gross margin 46.2 % 47.4 % LED Products gross profit 22.1 41.3 LED Products gross margin 19.2 % 28.1 % Total segment gross profit 81.1 101.7 Unallocated costs (6.9 ) (2.2 ) COGS acquisition related costs — (1.2 ) Consolidated gross profit $74.2 $98.3 Consolidated gross margin 30.6 % 35.8 % Geographic Information The Company conducts business in several geographic areas. Revenue is attributed to a particular geographic region based on the shipping address for the products. Disaggregated revenue from external customers by geographic area is as follows: Three months ended September 29, 2019 September 23, 2018 (in millions of U.S. Dollars) Revenue % of Revenue Revenue % of Revenue United States $55.4 23 % $66.2 24 % China 73.2 30 % 101.0 37 % Europe 63.0 26 % 69.8 25 % Other 51.2 21 % 37.2 14 % Total $242.8 $274.2 Assets by Reportable Segment Inventories are the only assets reviewed by the Company’s CODM when evaluating segment performance and allocating resources to the segments. The CODM reviews all of the Company's assets other than inventories on a consolidated basis. Unallocated inventories in the table below were not allocated to the reportable segments because the Company’s CODM does not review them when evaluating performance and allocating resources to each segment. Unallocated inventories consisted primarily of manufacturing employees’ stock-based compensation, profit sharing and quarterly or annual incentive compensation, matching contributions under the Company’s 401(k) plan, and acquisition related costs. Inventories for each of the Company's segments were as follows: September 29, 2019 June 30, 2019 Wolfspeed $90.3 $81.6 LED Products 86.5 99.2 Total segment inventories 176.8 180.8 Unallocated inventories 6.1 6.6 Consolidated inventories $182.9 $187.4

Restructuring

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring The Company has approved various operational plans that include restructuring costs. All restructuring costs are recorded in other operating expense on the consolidated statement of operations. Corporate Restructuring In April 2018, the Company approved a corporate restructuring plan. The purpose was to restructure and realign the Company's cost base with the long-range business strategy that was announced in February 2018. The restructuring activity was completed in the second quarter of fiscal 2019. For the three months ended September 23, 2018, $2.6 million was expensed relating to this corporate restructuring plan. Factory Optimization Restructuring In May 2019, the Company started a significant, multi-year factory optimization plan anchored by a state-of-the-art, automated 200mm capable silicon carbide and GaN fabrication facility and a large materials factory at its U.S. campus headquarters in Durham, North Carolina. As part of the plan, the Company will incur restructuring charges associated with the movement of equipment as well as disposals on certain long-lived assets. The Company expects approximately $70.0 million in restructuring charges related to the factory optimization plan to be incurred through 2024. For the three months ended September 29, 2019 , the Company expensed and paid $1.2 million of restructuring charges related to the factory optimization plan. In September 2019, the Company announced the intent to build the new fabrication facility in Marcy, New York to complement the factory expansion underway at its U.S. campus headquarters in Durham, North Carolina. The Company is currently evaluating the impact of this decision on future restructuring charges. Sales Representatives Restructuring In July 2019, the Company realigned its sales resources as part of the Company's transition to a more focused semiconductor company. As a result, the Company recorded $0.8 million in contract termination costs during the three months ended September 29, 2019 , all of which is accrued in other current liabilities as of September 29, 2019 .

Basis of Presentation	Basis of Presentation The consolidated financial statements presented herein have been prepared by the Company and have not been audited. In the opinion of management, all normal and recurring adjustments necessary to fairly state the consolidated financial position, results of operations, comprehensive loss, shareholders' equity and cash flows at September 29, 2019 , and for all periods presented, have been made. All material intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 30, 2019 has been derived from the audited financial statements as of that date. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2019 (fiscal 2019 ). The results of operations for the three months ended September 29, 2019 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 28, 2020 (fiscal 2020 ). Historical periods presented include reclassifications to reflect discontinued operations (see Note 2, "Discontinued Operations"). The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities. Actual amounts could differ materially from those estimates.
Recently Adopted Accounting Pronouncements and Accounting Pronouncements Pending Adoption	Recently Adopted Accounting Pronouncements Leases In February 2016, the FASB issued ASU No. 2016-02: Leases (Topic 842) (ASC 842), and ASU 2018-10: Codification Improvements to ASC 842, Leases. These ASUs require that a lessee recognize in its statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term and requires enhanced disclosures about an entity’s leasing arrangements. The Company adopted this standard on July 1, 2019, under the modified retrospective transition approach with the cumulative effect of application recognized at the effective date, without adjustment to prior comparative periods. The Company elected to utilize the transition package of practical expedients that allows the Company to not reassess (1) whether any expired or existing contracts are leases, or contain leases, (2) the lease classification for any expired or existing leases, and (3) initial direct costs for any existing leases. Further, the Company elected the practical expedient to not separate lease and non-lease components for all leases and account for the combined lease and non-lease components as a single lease component. The Company also made an accounting policy election to exclude leases with an initial term of 12 months or less from the consolidated balance sheets. The adoption of the new standard resulted in the recognition of $12.2 million of lease liabilities with corresponding right-of-use assets of $12.3 million as of July 1, 2019. As required, the right-of-use assets include the effect of reclassifying certain balances including deferred and prepaid rent, a portion of facilities-related restructuring accrual reserves, and a favorable lease intangible asset previously recognized in connection with an acquisition. The Company did not have a cumulative-effect adjustment to retained earnings as a result of the adoption of the new standard. The standard did not materially impact the Company's results from operations and had no impact on cash flows. See Note 4 , "Leases," for additional disclosures, as required by the new standard. The reported results as of and for the three months ended September 29, 2019 reflect the application of the new accounting guidance, while the reported results for prior periods have not been adjusted and continue to be reported in accordance with the Company's historical accounting under ASC 840, Leases. Accounting Pronouncements Pending Adoption Credit Losses In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU introduces a new accounting model known as Credit Expected Credit Losses (“CECL”). CECL requires earlier recognition of credit losses, while also providing additional transparency about credit risk. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for receivables at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. This model replaces the multiple existing impairment models in current GAAP, which generally require that a loss be incurred before it is recognized. The new standard will also apply to receivables arising from revenue transactions such as contract assets and accounts receivables. There are other provisions within the standard affecting how impairments of other financial assets may be recorded and presented, as well as expanded disclosures. The Company will adopt this standard on June 29, 2020 and is currently evaluating the impact on its consolidated financial statements.
