Accounting Policies [Abstract] | |
The Company and Basis of Presentation | Note 1. The Company and Basis of Presentation SiTime Corporation (the “Company”) was incorporated in the State of Delaware in December 2003. The Company is a provider of silicon timing systems. The Company primarily supplies oscillator products that comprise a MEMS resonator and clock IC that is integrated into a package, as well as standalone resonators. The Company has also started to sample clock ICs. The Company’s products are designed to address a wide range of applications across a broad array of end markets. The Company operates a fabless business model and leverages its global network of distributors and resellers to address the broad set of end markets that it serves. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments of a normal, recurring nature, which are necessary to state fairly the financial information included therein. These financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in SiTime Corporation's Annual Report on Form 10-K for the fiscal year ended December 31, 2020. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The Company was a wholly-owned subsidiary of MegaChips Corporation (“MegaChips”), a fabless semiconductor company based in Japan and traded on the Tokyo Stock Exchange, until the Company completed its initial public offering in November 2019. On June 16, 2020, the Company completed a follow-on public offering, in which it issued and sold 1,525,000 shares of its common stock and MegaChips sold 2,500,000 of the Company’s common stock held by them On February 22, 2021, the Company completed an additional follow-on public offering, in which it issued and sold 1,500,000 shares of its common stock and MegaChips sold 1,500,000 of the Company’s common stock held by them MegaChips remains the largest stockholder of the Company and held approximately 31.5% of the Company’s outstanding common stock as of June 30, 2021. Outbreak of Coronavirus Disease 2019 (“the COVID-19 pandemic”) On March 11, 2020, the World Health Organization characterized the outbreak of the coronavirus disease known as COVID-19 as a global pandemic and recommended containment and mitigation measures. On March 13, 2020, the United States declared a national emergency concerning the outbreak, and several states and municipalities have declared public health emergencies. To combat the spread of the COVID-19 pandemic, the United States and other foreign countries in which the Company operates have imposed measures such as quarantines and “shelter-in-place” orders that are restricting business operations and travel and requiring individuals to work from home (“WFH”), which has impacted all aspects of the Company’s business as well as those of the third-parties we rely upon for our manufacturing, assembly, testing, shipping and other operations. The global health crisis caused by the COVID-19 pandemic has negatively impacted business activity across the globe and has impacted the Company's employees and operations. The inputs into the Company’s judgments and estimates consider the economic implications of the COVID-19 pandemic, as the Company knows them, on the Company’s critical and significant accounting estimates. The extent to which the COVID-19 pandemic may impact the Company’s business will depend on future developments, which are highly uncertain, including the future effects of the COVID-19 pandemic on its employees, customers, suppliers, results of operations, financial condition, or liquidity for the remainder of fiscal year 2021 . Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Significant Accounting Policies The Company’s significant accounting policies are disclosed in the Company’s audited consolidated financial statements and related notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2020. There had been no changes to these accounting policies except for the recently adopted accounting guidance as discussed below. Recently Adopted Accounting Guidance In December 2019, the Financial Accounting Standard Board (“FASB”) issued Accounting Standard Update (“ASU”) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. The adoption of this standard on January 1, 2021 did not have any impact on the Company’s consolidated financial position, results of operations or cash flows. There are no new a ccounting p ronouncements that are pending to be adopted by the Company. |

Income Taxes | Note 7. Income Taxes The quarterly provision for income taxes is based on applying the estimated annual effective tax rate to the year to date pre-tax income (loss), plus any discrete items. The Company updates its estimate of its annual effective tax rate at the end of each quarterly period. The estimate takes into account annual forecasted income (loss) before income taxes, the geographic mix of income (loss) before income taxes and any significant permanent tax items. The following table presents the provision for income taxes and the effective tax rates for the three and six months ended June 30, 2021 and 2020: Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 (in thousands) Income (loss) before income taxes $ 2,046 $ (5,604 ) $ (1,479 ) $ (10,695 ) Provision for (benefit) from income tax (23 ) 1 (63 ) (1 ) Effective tax rate 1.1 % 0 % 4.3 % 0 % The Company’s effective tax rate may vary from the U.S. federal statutory tax rate due to the change in the mix of earnings in tax jurisdictions with different statutory rates, benefits related to tax credits and the tax impact of non-deductible expenses, existence of full valuation allowance on its deferred tax assets, and other permanent differences between income (loss) before income taxes and taxable income (loss). A valuation allowance is established or maintained when, based on currently available information and other factors, it is more likely than not that all or a portion of the deferred tax assets will not be realized. The Company regularly assesses its valuation allowance against deferred tax assets on a jurisdiction by jurisdiction basis. The Company considers all available positive and negative evidence, including future reversals of temporary differences, projected future taxable income, tax planning strategies and recent financial results. Based on management’s assessment of the realizability of deferred tax assets, the Company continues to maintain a full valuation reserve on its deferred tax assets as of June 30, 2021 . As of June 30, 2021 and December 31, 2020, the Company had $ 2.4 The Company’s policy is to record interest and penalties related to unrecognized tax benefits as income tax expense.

Legal fees and other costs associated with such actions are expensed as incurred. The Company assesses, in conjunction with legal counsel, the need to record a liability for litigation and contingencies. Accrual estimates are recorded when and if it is determined that such a liability for litigation and contingencies are both probable and reasonably estimable. In March 2019, VTT Technical Research Centre of Finland, Ltd. ("VTT") filed suit in the United States District Court for the Northern District of California (“the Court”) alleging infringement by the Company of a patent relating to specific combinations of features set forth in U.S. Patent No. 8,558,643. The complaint sought unspecified monetary damages and injunctive relief. On January 22, 2020, the Company participated in a mediation that had been ordered by the Court. The case was not resolved at the mediation. A Markman Hearing was held on May 15, 2020 relating to a number of different disputed claim terms, and on July 9, 2020 the Court issued a Markman Order relating to those disputed claim terms. Among its determinations, the Court found that one of the disputed claim terms was indefinite, as well as any claim that had this claim term in it. On July 17, 2020, the Court issued a judgment finding all claims of U.S. Patent No. 8,558,643 invalid, based upon its Markman Order. VTT filed a Notice of Appeal of the Court's judgment with the US Court of Appeals for the Federal Circuit (“CAFC”) and filed its opening brief on November 19, 2020 and the Company filed its response brief on January 28, 2021. VTT filed its reply on March 4, 2021. On June 9, 2021, a hearing was held at the CAFC and on June 10, 2021 the CAFC affirmed the Court’s judgment. Indemnification The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify other parties to such agreements with respect to certain matters. Typically, these obligations arise in the context of contracts that the Company has entered into, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations and covenants or terms and conditions related to such matters as the sale and/or delivery of its products, title to assets sold, certain intellectual property claims, defective products, specified environmental matters, and certain income taxes. Further, the Company’s obligations under these agreements may be limited in terms of time, amount, or the scope of its responsibility and in some instances, the Company may have recourse against third-parties for certain payments made under these agreements. It is not possible to predict the maximum potential amount of future payments under these agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, the Company has had no material indemnification claims under these agreements. |

Outbreak of Coronavirus Disease 2019 ("the COVID-19 pandemic") | Outbreak of Coronavirus Disease 2019 (“the COVID-19 pandemic”) On March 11, 2020, the World Health Organization characterized the outbreak of the coronavirus disease known as COVID-19 as a global pandemic and recommended containment and mitigation measures. On March 13, 2020, the United States declared a national emergency concerning the outbreak, and several states and municipalities have declared public health emergencies. To combat the spread of the COVID-19 pandemic, the United States and other foreign countries in which the Company operates have imposed measures such as quarantines and “shelter-in-place” orders that are restricting business operations and travel and requiring individuals to work from home (“WFH”), which has impacted all aspects of the Company’s business as well as those of the third-parties we rely upon for our manufacturing, assembly, testing, shipping and other operations. The global health crisis caused by the COVID-19 pandemic has negatively impacted business activity across the globe and has impacted the Company's employees and operations. The inputs into the Company’s judgments and estimates consider the economic implications of the COVID-19 pandemic, as the Company knows them, on the Company’s critical and significant accounting estimates. The extent to which the COVID-19 pandemic may impact the Company’s business will depend on future developments, which are highly uncertain, including the future effects of the COVID-19 pandemic on its employees, customers, suppliers, results of operations, financial condition, or liquidity for the remainder of fiscal year 2021 . |
