DESCRIPTION OF BUSINESS [Abstract] | |
DESCRIPTION OF BUSINESS | NOTE 1 – DESCRIPTION OF BUSINESS A CM Research, Inc. (“ACM”) and its subsidiaries (collectively with ACM, the “Company”) develop, manufacture and sell wet cleaning and other equipment used to improve the manufacturing process and yield for advanced integrated chips. The Company markets and sells its wet-cleaning equipment under the brand name “Ultra C,” based on the Company’s proprietary Space Alternated Phase Shift (“SAPS”), Timely Energized Bubble Oscillation (“TEBO”), and Tahoe technologies. These tools are designed to remove random defects from a wafer surface efficiently, without damaging the wafer or its features, even at increasingly advanced process nodes. ACM was incorporated in California in 1998, and it initially focused on developing tools for manufacturing process steps involving the integration of ultra low-K materials and copper. The Company’s early efforts focused on stress-free copper-polishing technology, and it sold tools based on that technology in the early 2000s. In 2006 the Company established its operational center in Shanghai in the People’s Republic of China (the “PRC”), where it operates through ACM’s subsidiary ACM Research (Shanghai), Inc. (“ACM Shanghai”). ACM Shanghai was formed to help establish and build relationships with integrated circuit manufacturers in the PRC, and the Company initially financed its Shanghai operations in part through sales of non-controlling equity interests in ACM Shanghai. In 2007 the Company began to focus its development efforts on single-wafer wet-cleaning solutions for the front-end chip fabrication process. The Company introduced its SAPS megasonic technology, which can be applied in wet wafer cleaning at numerous steps during the chip fabrication process, in 2009. It introduced its TEBO technology, which can be applied at numerous steps during the fabrication of small node two-dimensional conventional and three-dimensional patterned wafers, in March 2016. The Company has designed its equipment models for SAPS and TEBO solutions using a modular configuration that enables it to create a wet-cleaning tool meeting the specific requirements of a customer, while using pre-existing designs for chamber, electrical, chemical delivery and other modules. In August 2018, the Company introduced its Ultra-C Tahoe wafer cleaning tool, which can deliver high cleaning performance with significantly less sulfuric acid than typically consumed by conventional high-temperature single-wafer cleaning tools. Based on its electro-chemical plating (“ECP”) technology, in 2019 the Company introduced its Ultra ECP ap, or “Advanced Packaging,” tool for bumping, or applying copper, tin and nickel to semiconductor wafers at the die-level, and its Ultra ECP map, or “Multi-Anode Partial Plating,” tool to deliver advanced electrochemical copper plating for copper interconnect applications in front-end wafer fabrication processes. The Company also offers a range of custom-made equipment, including cleaners, coaters and developers, to back-end wafer assembly and packaging factories, principally in the PRC. In 2011 ACM Shanghai formed a wholly owned subsidiary in the PRC, ACM Research (Wuxi), Inc. (“ACM Wuxi”), to manage sales and service operations. In November 2016 ACM redomesticated from California to Delaware pursuant to a merger in which ACM Research, Inc., a California corporation, was merged into a newly formed, wholly owned Delaware subsidiary, also named ACM Research, Inc. In June 2017 ACM formed a wholly owned subsidiary in Hong Kong, CleanChip Technologies Limited (“CleanChip”), to act on the Company’s behalf in Asian markets outside the PRC by, for example, serving as a trading partner between ACM Shanghai and its customers, procuring raw materials and components, performing sales and marketing activities, and making strategic investments. In August 2017 ACM purchased of ACM Shanghai’s equity interests held by Shanghai Science and Technology Venture Capital Co., Ltd. On November 8, 2017, ACM purchased the remaining of ACM Shanghai’s equity interest held by third parties, Shanghai Pudong High-Tech Investment Co., Ltd. (“PDHTI”) and Shanghai Zhangjiang Science & Technology Venture Capital Co., Ltd. (“ZSTVC”). At December 31, 2017, ACM owned all of the outstanding equity interests of ACM Shanghai, and indirectly through ACM Shanghai, owned all of the outstanding equity interests of ACM Wuxi. On September 13, 2017, ACM effectuated a 1-for-3 reverse stock split of Class A and Class B common stock. Unless otherwise indicated, all share numbers, per share amount, share prices, exercise prices and conversion rates set forth in these notes and the accompanying consolidated financial statements have been adjusted retrospectively to reflect the reverse stock split. On November 2, 2017, the Registration Statement on Form S-1 (File No. 333- 220451) for ACM’s initial public offering of Class A common stock was declared effective by the U.S. Securities and Exchange Commission. Shares of Class A common stock began trading on the Nasdaq Global Market on November 3, 2017, and the closing for the offering was held on November 7, 2017.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract] | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation The Company’s condensed consolidated financial statements include the accounts of ACM and its subsidiaries, including ACM Shanghai and its subsidiaries, which include ACM Wuxi, ACM Shengwei and CleanChip (the subsidiaries of which include ACM California and ACM Korea). ACM’s subsidiaries are those entities in which ACM, directly or indirectly, controls a majority of the voting power. All significant intercompany transactions and balances have been eliminated upon consolidation. The accompanying condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission for reporting on Form -Q. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. The accompanying condensed consolidated financial statements should be read in conjunction with the historical consolidated financial statements of the Company for the year ended December included in ACM’s Annual Report on Form -K for the year ended December . The accompanying condensed consolidated balance sheet as of September condensed consolidated statements of operations and comprehensive income for the and months ended September and condensed consolidated statements of changes in stockholders’ equity for the and months ended September and and condensed consolidated statements of cash flows for the months ended September and are unaudited. In the opinion of management, these unaudited condensed consolidated financial statements of the Company reflect all adjustments that are necessary for a fair presentation of the Company’s financial position and results of operations. Such adjustments are of a normal recurring nature, unless otherwise noted. The balance sheet as of September and the results of operations for the and months ended September are not necessarily indicative of the results to be expected for any future period. COVID-19 Assessment The outbreak of COVID- the coronavirus, has grown both in the United States and globally, and related government and private sector responsive actions have adversely affected the Company’s business operations. In December a series of emergency quarantine measures taken by the PRC government disrupted domestic business activities during the weeks after the initial outbreak of COVID- Since that time, an increasing number of countries, including the United States, have imposed restrictions on travel to and from the PRC and elsewhere, as well as general movement restrictions, business closures and other measures imposed to slow the spread of COVID- The situation continues to develop, and it is impossible to predict the effect and ultimate impact of the COVID- outbreak on the Company’s business operations and results. While the quarantine, social distancing and other regulatory measures instituted or recommended in response to COVID- are expected to be temporary, the duration of the business disruptions and related financial impact cannot be estimated at this time. The COVID- outbreak has been declared a worldwide health pandemic that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn and changes in global economic policy that could reduce demand for the Company’s products and its customers’ chips and have a material adverse impact on the Company’s business, operating results and financial condition. Through September the Company had not experienced a significant negative impact of COVID- on its operations, capital and financial resources, including overall liquidity position. The Company continues to monitor the impact of the COVID-19 pandemic on all aspects of its business. The Company conducts substantially all of its product development, manufacturing, support and services in the PRC, and those activities have been directly impacted by the COVID- outbreak and related restrictions on transportation and public appearances. In February ACM Shanghai’s headquarters were closed for an additional beyond the normal Lunar New Year Holiday in accordance with Shanghai government restrictions related to the outbreak. The Company cannot assure that further closures or reductions of its PRC operations or production may not be necessary in upcoming months as the result of business interruptions arising from protective measures being taken by the PRC and other governmental agencies or of other consequences of the COVID- outbreak. The Company’s corporate headquarters are located in Alameda County in the San Francisco Bay Area of California. The effects of any future actions by the State of California, the San Francisco Department of Public Health, health officers of the San Francisco Bay Area counties or other local health officials that intended to mitigate the COVID-19 pandemic may negatively impact productivity, disrupt the business of the Company and delay timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on the Company’s ability to conduct its business in the ordinary course. The prolonged and broad-based shift to a remote working environment continues to create inherent productivity, connectivity, and oversight challenges and could affect our ability to enhance, develop and support existing products and services, detect and prevent spam and problematic content, hold product sales and marketing events, and generate new sales leads, among others. In addition, the changed environment under which the Company is operating could have an effect on its internal controls over financial reporting as well as the Company’s ability to meet a number of its compliance requirements in a timely or quality manner. Additional and/or extended, governmental lockdowns, restrictions or new regulations could significantly impact the ability of our employees and vendors to work productively. Governmental restrictions have been globally inconsistent and it remains unclear when a return to worksite locations or travel will be permitted or what restrictions will be in place in those environments. As the Company continues to return its workforce in more office locations in it may experience increased costs as it prepares its facilities for a safe return to work environment and experiment with hybrid work models, in addition to potential effects on its ability to compete effectively and maintain its corporate culture. Extended periods of interruption to the Company’s corporate, development or manufacturing facilities due to the COVID- outbreak could cause the Company to lose revenue and market share, which would depress its financial performance and could be difficult to recapture. The Company’s business may also be harmed if travel to or from the PRC or the United States continues to be restricted or inadvisable or if members of management and other employees are absent because they contract the coronavirus, they elect not to come to work due to the illness affecting others in the Company’s office or laboratory facilities, or they are subject to quarantines or other governmentally imposed restrictions. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet date and the reported revenues and expenses during the reported period in the consolidated financial statements and accompanying notes. The Company’s significant accounting estimates and assumptions include, but are not limited to, those used for the valuation and recognition of fair value of trading securities, stock-based compensation arrangements and warrant liability, realization of deferred tax assets, assessment for impairment of long-lived assets, allowance for doubtful accounts, inventory valuation for excess and obsolete inventories, lower of cost and market value or net realizable value of inventories, depreciable lives of property and equipment and useful life of intangible assets. Management evaluates these estimates and assumptions on a regular basis. Actual results could differ from those estimates and assumptions. Basic and Diluted Net Income per Common Share Basic and diluted net income per common share are calculated as follows: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Numerator: Net income $ 11,150 $ 10,020 $ 24,306 $ 12,479 Less: Net income attributable to non-controlling interests and redeemable non-controlling interests 995 1,393 2,114 2,228 Net income available to common stockholders, basic and diluted $ 10,155 $ 8,627 $ 22,192 $ 10,251 Weighted average shares outstanding, basic 19,422,546 18,201,943 19,113,353 18,124,665 Effect of dilutive securities 2,619,970 3,353,353 2,616,987 3,132,996 Weighted average shares outstanding, diluted 22,042,516 21,555,296 21,730,340 21,257,661 Net income per common share: Basic $ 0.52 $ 0.47 $ 1.16 $ 0.57 Diluted $ 0.46 $ 0.40 $ 1.02 $ 0.48 ACM has been authorized to issue Class A and Class B common stock since redomesticating in Delaware in November The classes of common stock are substantially identical in all material respects, except for voting rights. Since ACM did not declare any dividends during the and nine months ended September and the net income per common share attributable to each class is the same under the “ -class” method. As such, the classes of common stock have been presented on a combined basis in the condensed consolidated statements of operations and comprehensive income and in the above computation of net income per common share. Diluted net income per common share reflects the potential dilution from securities, including stock options and issued warrants, that could share in ACM’s earnings. Certain potential dilutive securities were excluded from the net income per share calculation because the impact would be anti-dilutive. ACM’s potential dilutive securities consist of warrants and stock options for the months ended September ’ Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents and accounts receivable. The Company deposits and invests its cash with financial institutions that management believes are creditworthy. The Company is potentially subject to concentrations of credit risks in its accounts receivable. For the nine months ended September Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2019 - 12, Income Taxes (Topic 740) : Simplifying the Accounting for Income Taxes . ASU 2019 - 12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. It also improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The Company adopted ASU 2019 - 12 on January 1, 2021. The adoption of ASU 2019 - 12 did not have a material impact on the Company’s condensed consolidated financial statements. In March the FASB issued ASU No. - Reference Rate Reform (Topic : Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU - provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform. The Company adopted ASU - on January The adoption of ASU - did not have a material impact on the Company’s condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In June the FASB issued ASU - Financial Instruments-Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments . ASU - replaced the pre-existing incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU - requires use of a forward-looking expected credit loss model for accounts receivables, loans and other financial instruments. ASU - is effective for fiscal years beginning after December with early adoption permitted. In October the FASB issued ASU - Financial Instruments – Credit Losses (Topic 326) , Derivatives and Hedging (Topic 815) and Leases (Topic 842) , which defers the effective date for public filers that are considered small reporting companies (“SRC”) as defined by the U.S. Securities and Exchange Commission (“SEC”) to fiscal years beginning after December including interim periods within those fiscal years. Since the Company was eligible to be an SRC based on its SRC determination as of November (which is the issuance date of ASU - in accordance with SEC regulations, the Company will adopt the standards for the year beginning January Adoption of the standard requires using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the effective date to align existing credit loss methodology with the new standard. The Company is evaluating the impact of this standard on its consolidated financial statements, including accounting policies, processes and systems and expects the standard will have a minor impact on its consolidated financial statements. |

LEASES [Abstract] | |
LEASES | NOTE 11 – LEASES The Company leases space under non-cancelable operating leases for several office and manufacturing locations. These leases do not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. Further, the leases do not contain contingent rent provisions. Most leases include one or more options to renew. The exercise of lease renewal options is typically at the Company’s sole discretion; therefore, the majority of renewals to extend the lease terms are not included in the Company’s right-of-use assets and lease liabilities as they are not reasonably certain of exercise. The Company regularly evaluates the renewal options, and when they are reasonably certain of exercise, the Company includes the renewal period in its lease term. As 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 the lease payments. The Company has a centrally managed treasury function; therefore, based on the applicable lease terms and the current economic environment, it applies a portfolio approach for determining the incremental borrowing rate. The components of lease expense were as follows: Three Months Ended September 30, Nine September 30 2021 2020 2021 2020 Operating lease cost $ 632 $ 384 $ 1,807 $ 1,139 Short-term lease cost 105 73 258 170 Lease cost $ 737 $ 457 $ 2,065 $ 1,309 Supplemental cash flow information related to operating leases was as follows for the three and nine months ended September 30, 2021 and 2020 Three Months Ended September 30, Nine September 30 2021 2020 2021 2020 Cash paid for amounts included in the measurement of lease liabilities: Operating cash outflow from operating leases $ 737 $ 457 $ 2,065 $ 1,309 Maturities of lease liabilities for all operating leases were as follows as of September 30, 2021 December 31, 2021 631 2022 2,292 2023 1,020 2024 914 2025 19 Total lease payments 4,876 Less: Interest (277 ) Present value of lease liabilities $ 4,599 The weighted average remaining lease terms and discount rates for all operating leases were as follows as of September 30 and December : September 30, 2021 December 31, 2020 Remaining lease term and discount rate: Weighted average remaining lease term (years) 1.50 2.11 Weighted average discount rate 4.58 % 5.14 % |

FINANCIAL LIABILITY CARRIED AT FAIR VALUE [Abstract] | |
FINANCIAL LIABILITY CARRIED AT FAIR VALUE | NOTE 15 – FINANCIAL LIABILITY CARRIED AT FAIR VALUE In December 2016 Shengxin (Shanghai) Management Consulting Limited Partnership (“SMC”) paid 20,123,500 RMB ($2,981 as of the date of funding) (the “SMC Investment”) to ACM Shanghai as an investment pursuant to terms to be subsequently negotiated. SMC is a PRC limited partnership partially owned by employees of ACM Shanghai. In March 2017 (a) ACM issued to SMC a warrant (the “2017 Warrant”) exercisable to purchase 397,502 shares of Class A common stock at a price of $7.50 per share, for a total exercise price of $2,981, and (b) ACM Shanghai agreed to repay the SMC Investment within 60 days after the exercise of the 2017 Warrant. In March 2018 SMC exercised the 2017 Warrant in full, as a result of which (1) ACM issued 397,502 shares of Class A common stock to SMC (the “2017 Warrant Shares”), (2) SMC borrowed the funds to pay the 2017 Warrant exercise price pursuant to a senior secured promissory note (the “SMC Note”) in the principal amount of $2,981 issued to ACM Shanghai, which in turn issued to ACM a promissory note (the “Intercompany Note”) in the principal amount of $2,981 in payment of the 2017 Warrant exercise price. Each of the SMC Note and the Intercompany Note bore interest at a rate of 3.01% per annum and matured on August 17, 2023. The SMC Note was secured by a pledge of the 2017 Warrant Shares. In connection with its follow-on public offering of Class A common stock in August 2019, ACM agreed to purchase a total of 154,821 of the 2017 Warrant Shares from SMC at a per share price of $13.195, of which (a) $1,161 was applied to reduce SMC’s obligations to ACM Shanghai under the SMC Note, and which ACM then withheld for its own account and applied to reduce ACM Shanghai’s obligations to ACM under the Intercompany Note, and (b) the remaining $882 was paid to SMC. In a separate transaction, ACM Shanghai repaid $1,161 of the SMC Investment in cash, which reduced the amount of the SMC Investment due to SMC to $1,820. The SMC Note and SMC Investment were offsetting items in the Company’s consolidated balance sheet in accordance with ASC 210-20-45-1 up to April 30, 2020. In preparation for the STAR IPO, ACM Shanghai was required to terminate its financial relationship with SMC. In order to facilitate such termination, on April 30, 2020, ACM entered into two agreements relating to outstanding obligations among ACM Research, ACM Shanghai and SMC. Pursuant to such agreements: (i) ACM Shanghai assigned to ACM its rights under the SMC Note, including the right to receive payment of the $1,820 payable thereunder; (ii) ACM cancelled the outstanding $1,820 obligation of ACM Shanghai under the Intercompany Note; (iii) SMC surrendered its remaining 242,681 2017 Warrant Shares to ACM Research; and (iv) in exchange for such 242,681 2017 Warrant Shares, ACM agreed to deliver to SMC certain consideration (“SMC Consideration”) agreed upon by ACM Research and SMC, subject to obtaining certain PRC regulatory approvals. Under the agreements, if the required approvals were not obtained by December 31, 2023, ACM would cancel the SMC Note as consideration for the 242,681 2017 Warrant Shares. In a separate transaction in April 2020, ACM Shanghai repaid the remaining $1,820 of the SMC Investment in cash. Beginning April 30, 2020, the SMC Consideration was accounted for as a financial liability, and the Company applied the fair value measurement option to value the SMC Consideration in accordance with ASC 825-10-15-4a. On April 30, 2020, the SMC Consideration was $9,715, which reflected cancellation of the 2017 Warrant Shares and was recorded in equity. The financial liability was remeasured to fair value as of the end of each subsequent reporting period. On July 29, 2020, ACM and SMC entered into an amended agreement under which, in settlement of the SMC Consideration, ACM issued to SMC a warrant (the “2020 Warrant”) to purchase 242,681 shares of Class A common stock at a purchase price of $7.50 per share, and ACM cancelled the SMC Note. The financial liability was remeasured to fair value of $21,679 as of July 29, 2020, and was retired with the issuance of the 2020 Warrant. The Company recognized a change in fair value of financial liability of $11,964 for the year ended December 31, 2020, which was reflected in the consolidated statement of operations. The Company recorded the difference of $19,859 between the 2020 Warrant of $21,679 and the SMC Note of $1,820 into equity. The 2020 Warrant was initially measured at fair value at the issuance date and classified as equity permanently in accordance with ASC 815. The fair value of the 2020 Warrant amounted to $21,679, based on the grant date using the Black-Scholes valuation model with the following assumptions: July 29, 2020 Fair value of common share(1) $ 89.28 Expected term in years(2) 3.42 Volatility(3) 47.42 % Risk-free interest rate(4) 0.15 % Expected dividend(5) 0 % (1) Fair value of Class A common stock was the closing market price of the Class A common stock on July 29, 2020. (2) Expected term of share options was based on the average of the vesting period and the contractual term for each grant according to Staff Accounting Bulletin 110. (3) Volatility was calculated based on the historical volatility of the stock of companies comparable to ACM in the period equal to the expected term of each grant. (4) Risk-free interest rate was based on the yields of U.S. Treasury securities with maturities similar to the expected term of the share options in effect at the time of grant. (5) Expected dividend was assumed to be 0%, as ACM had no history or expectation of paying a dividend on its common stock. On June 9, 2021, subsequent to its obtaining the necessary PRC approvals, SMC exercised the 2020 Warrant by paying the $ exercise price to ACM and surrendering the 2020 Warrant to ACM. In return, ACM delivered shares of ACM Class A common stock to SMC. |

STOCK-BASED COMPENSATION [Abstract] | |
STOCK-BASED COMPENSATION | NOTE 20 – STOCK-BASED COMPENSATION In January 2020 ACM Shanghai adopted a 2019 Stock Option Incentive Plan (the “Subsidiary Stock Option Plan”) that provides for, among other incentives, the granting to officers, directors, employees of options to purchase shares of ACM Shanghai’s common stock. The fair value of the stock options granted is estimated at the date of grant based on the Black-Scholes option pricing model using assumptions generally consistent with those used for ACM’s stock options. Because ACM Shanghai shares are not publicly traded, the expected volatility is estimated with reference to the average historical volatility of a group of publicly traded companies that are believed to have similar characteristics to ACM Shanghai. ACM’s stock-based compensation consists of employee and non-employee awards issued under its 1998 Stock Option Plan, its 2016 Omnibus Incentive Plan, and as standalone options. ACM granted stock options to employees under the 2016 Omnibus Incentive Plan during the three and nine months ended September 30, 2021. The vesting condition may consist of a service period determined by the Board of Directors for a grant or certain performance conditions determined by the Board of Directors for a grant. The fair value of the stock options granted with service period based condition is estimated at the date of grant using the Black-Scholes option pricing model. The fair value of the stock options granted with market based condition is estimated at the date of grant using the Monte Carlo simulation model. The following table summarizes the components of stock-based compensation expense included in the consolidated statements of operations: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Stock-Based Compensation Expense: Cost of revenue $ 108 $ 44 $ 289 $ 132 Sales and marketing expense 417 237 1,400 495 Research and development expense 293 193 801 568 General and administrative expense 460 2,305 1,333 3,128 $ 1,278 $ 2,779 $ 3,823 $ 4,323 Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Stock-based compensation expense by type: Employee stock purchase plan $ 1,179 $ 2,651 $ 3,481 $ 3,717 Non-employee stock purchase plan 12 44 82 356 Subsidiary option grants 87 84 260 250 $ 1,278 $ 2,779 $ 3,823 $ 4,323 The following table summarizes the Company’s employee share option activities during the nine months ended September 30, 2021: Number of Option Share Weighted Average Grant Date Fair Value Weighted Average Exercise Price Weighted Average Remaining Contractual Term Outstanding at December 31, 2020 3,191,411 $ 5.13 $ 12.73 7.13 years Granted 138,400 48.18 106.15 Exercised (443,683 ) 2.39 6.15 Forfeited/cancelled (33,404 ) 32.66 73.94 Outstanding at September 30, 2021 2,852,724 $ 7.32 $ 17.57 6.78 years Vested and exercisable at September 30, 2021 1,844,193 As of September 30, 2021 and December 31, 2020, $ and $ , respectively, of total unrecognized employee stock-based compensation expense, net of estimated forfeitures, related to stock-based awards for ACM were expected to be recognized over a weighted-average period of years and years, respectively.

INCOME TAXES [Abstract] | |
INCOME TAXES | NOTE 21 – INCOME TAXES Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period during which such rates are enacted. The Company considers all available evidence to determine whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become realizable. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carry-forward periods) and projected taxable income in assessing the realizability of deferred tax assets. In making such judgments, significant weight is given to evidence that can be objectively verified. As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. Prior to September 30, 2019, the Company had recorded a valuation allowance for the full amount of net deferred tax assets in the United States, as the realization of deferred tax assets was uncertain. Since September 30, 2019, the Company has not maintained a valuation allowance except for a partial valuation allowance on certain U.S. deferred tax assets. In order to recognize the remaining U.S. deferred tax assets that continue to be subject to a valuation allowance, the Company will need to generate sufficient U.S. taxable income in future periods before the expiration of the deferred tax assets governed by the tax code. ACM Shanghai has shown a three-year historical cumulative profit and has projections of future income. As a result, the Company does not maintain a valuation allowance. The Company accounts for uncertain tax positions in accordance with the authoritative guidance on income taxes under which the Company may only recognize or continue to recognize tax positions that meet a more likely than not threshold. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes. The Company’s effective tax rate differs from statutory rates of 21% for U.S. federal income tax purposes and 12.5% to 25% for Chinese income tax purposes due to the effects of the valuation allowance and certain permanent differences from book-tax differences. As a result, the Company recorded income tax benefit (expense) of $3,021 and $(416) during the nine months ended September 30, 2021 and 2020, respectively . As of September 30, 2021, the Company’s total unrecognized tax benefits were $570 of which $422 would affect the effective tax rate if recognized. The Company will recognize interest and penalties, when they occur, related to uncertain tax provisions as a component of tax expense. No interest or penalties were recognized for the nine months ended September 30, 2021. The Company files income tax returns in the United States and state and foreign jurisdictions.

COMMITMENTS AND CONTINGENCIES | NOTE 22 – COMMITMENTS AND CONTINGENCIES The Company leases offices under non-cancelable operating lease agreements. See note for future minimum lease payments under non-cancelable operating lease agreements with initial terms of year or more. As of September the Company had of open capital commitments. Covenants in ACM Shengwei’s Grant Contract for State-owned Construction Land Use Right in Shanghai City with the China (Shanghai) Pilot Free Trade Zone Lingang Special Area Administration require, among other things, that ACM Shengwei pay liquidated damages in the event that (a) it does not make a total investment (including the costs of construction, fixtures, equipment and grant fees) of at least RMB 450.0 million ($63,400) or (b) within six years after the land use right is obtained, the Company does not (i) generate a minimum specified amount of annual sales of products manufactured on the granted land or (ii) pay to the PRC at least RMB 157.6 million ($22,000) in annual total taxes (including value-added taxes, corporate income tax, personal income taxes, urban maintenance and construction taxes, education surcharges, stamp taxes, and vehicle and shipping taxes) as a result of operations in connection with the granted land. As of September 30, 2021, the Company had paid in total $10,977 for its Lingang-related investments. In the normal course of business, the Company is subject to contingencies, including legal proceedings and environmental claims arising out of the normal course of businesses that relate to a wide range of matters, including among others, contracts breach liability. The Company records accruals for such contingencies based upon the assessment of the probability of occurrence and, where determinable, an estimate of the liability. Management may consider many factors in making these assessments including past history, scientific evidence and the specifics of each matter. Some of these contingencies involve claims that are subject to substantial uncertainties and unascertainable damages. The Company’s management has evaluated all such proceedings and claims that existed as of September 30, 2021 and December 31, 2020. In the opinion of management, no provision for liability nor disclosure was required as of September 30, 2021 related to any claim against the Company because: (a) there is not a reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim; (b) a reasonably possible loss or range of loss cannot be estimated; or (c) such estimate is immaterial. As of September 30, 2021, the Company had one outstanding legal proceeding.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract] | |
Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The Company’s condensed consolidated financial statements include the accounts of ACM and its subsidiaries, including ACM Shanghai and its subsidiaries, which include ACM Wuxi, ACM Shengwei and CleanChip (the subsidiaries of which include ACM California and ACM Korea). ACM’s subsidiaries are those entities in which ACM, directly or indirectly, controls a majority of the voting power. All significant intercompany transactions and balances have been eliminated upon consolidation. The accompanying condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission for reporting on Form -Q. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. The accompanying condensed consolidated financial statements should be read in conjunction with the historical consolidated financial statements of the Company for the year ended December included in ACM’s Annual Report on Form -K for the year ended December . The accompanying condensed consolidated balance sheet as of September condensed consolidated statements of operations and comprehensive income for the and months ended September and condensed consolidated statements of changes in stockholders’ equity for the and months ended September and and condensed consolidated statements of cash flows for the months ended September and are unaudited. In the opinion of management, these unaudited condensed consolidated financial statements of the Company reflect all adjustments that are necessary for a fair presentation of the Company’s financial position and results of operations. Such adjustments are of a normal recurring nature, unless otherwise noted. The balance sheet as of September and the results of operations for the and months ended September are not necessarily indicative of the results to be expected for any future period. |
COVID-19 Assessment | COVID-19 Assessment The outbreak of COVID- the coronavirus, has grown both in the United States and globally, and related government and private sector responsive actions have adversely affected the Company’s business operations. In December a series of emergency quarantine measures taken by the PRC government disrupted domestic business activities during the weeks after the initial outbreak of COVID- Since that time, an increasing number of countries, including the United States, have imposed restrictions on travel to and from the PRC and elsewhere, as well as general movement restrictions, business closures and other measures imposed to slow the spread of COVID- The situation continues to develop, and it is impossible to predict the effect and ultimate impact of the COVID- outbreak on the Company’s business operations and results. While the quarantine, social distancing and other regulatory measures instituted or recommended in response to COVID- are expected to be temporary, the duration of the business disruptions and related financial impact cannot be estimated at this time. The COVID- outbreak has been declared a worldwide health pandemic that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn and changes in global economic policy that could reduce demand for the Company’s products and its customers’ chips and have a material adverse impact on the Company’s business, operating results and financial condition. Through September the Company had not experienced a significant negative impact of COVID- on its operations, capital and financial resources, including overall liquidity position. The Company continues to monitor the impact of the COVID-19 pandemic on all aspects of its business. The Company conducts substantially all of its product development, manufacturing, support and services in the PRC, and those activities have been directly impacted by the COVID- outbreak and related restrictions on transportation and public appearances. In February ACM Shanghai’s headquarters were closed for an additional beyond the normal Lunar New Year Holiday in accordance with Shanghai government restrictions related to the outbreak. The Company cannot assure that further closures or reductions of its PRC operations or production may not be necessary in upcoming months as the result of business interruptions arising from protective measures being taken by the PRC and other governmental agencies or of other consequences of the COVID- outbreak. The Company’s corporate headquarters are located in Alameda County in the San Francisco Bay Area of California. The effects of any future actions by the State of California, the San Francisco Department of Public Health, health officers of the San Francisco Bay Area counties or other local health officials that intended to mitigate the COVID-19 pandemic may negatively impact productivity, disrupt the business of the Company and delay timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on the Company’s ability to conduct its business in the ordinary course. The prolonged and broad-based shift to a remote working environment continues to create inherent productivity, connectivity, and oversight challenges and could affect our ability to enhance, develop and support existing products and services, detect and prevent spam and problematic content, hold product sales and marketing events, and generate new sales leads, among others. In addition, the changed environment under which the Company is operating could have an effect on its internal controls over financial reporting as well as the Company’s ability to meet a number of its compliance requirements in a timely or quality manner. Additional and/or extended, governmental lockdowns, restrictions or new regulations could significantly impact the ability of our employees and vendors to work productively. Governmental restrictions have been globally inconsistent and it remains unclear when a return to worksite locations or travel will be permitted or what restrictions will be in place in those environments. As the Company continues to return its workforce in more office locations in it may experience increased costs as it prepares its facilities for a safe return to work environment and experiment with hybrid work models, in addition to potential effects on its ability to compete effectively and maintain its corporate culture. Extended periods of interruption to the Company’s corporate, development or manufacturing facilities due to the COVID- outbreak could cause the Company to lose revenue and market share, which would depress its financial performance and could be difficult to recapture. The Company’s business may also be harmed if travel to or from the PRC or the United States continues to be restricted or inadvisable or if members of management and other employees are absent because they contract the coronavirus, they elect not to come to work due to the illness affecting others in the Company’s office or laboratory facilities, or they are subject to quarantines or other governmentally imposed restrictions. |
Use of Estimates | Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet date and the reported revenues and expenses during the reported period in the consolidated financial statements and accompanying notes. The Company’s significant accounting estimates and assumptions include, but are not limited to, those used for the valuation and recognition of fair value of trading securities, stock-based compensation arrangements and warrant liability, realization of deferred tax assets, assessment for impairment of long-lived assets, allowance for doubtful accounts, inventory valuation for excess and obsolete inventories, lower of cost and market value or net realizable value of inventories, depreciable lives of property and equipment and useful life of intangible assets. Management evaluates these estimates and assumptions on a regular basis. Actual results could differ from those estimates and assumptions. |

Since ACM did not declare any dividends during the and nine months ended September and the net income per common share attributable to each class is the same under the “ -class” method. As such, the classes of common stock have been presented on a combined basis in the condensed consolidated statements of operations and comprehensive income and in the above computation of net income per common share. Diluted net income per common share reflects the potential dilution from securities, including stock options and issued warrants, that could share in ACM’s earnings. Certain potential dilutive securities were excluded from the net income per share calculation because the impact would be anti-dilutive. ACM’s potential dilutive securities consist of warrants and stock options for the months ended September ’ |

Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2019 - 12, Income Taxes (Topic 740) : Simplifying the Accounting for Income Taxes . ASU 2019 - 12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. It also improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The Company adopted ASU 2019 - 12 on January 1, 2021. The adoption of ASU 2019 - 12 did not have a material impact on the Company’s condensed consolidated financial statements. In March the FASB issued ASU No. - Reference Rate Reform (Topic : Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU - provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform. The Company adopted ASU - on January The adoption of ASU - did not have a material impact on the Company’s condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In June the FASB issued ASU - Financial Instruments-Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments . ASU - replaced the pre-existing incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU - requires use of a forward-looking expected credit loss model for accounts receivables, loans and other financial instruments. ASU - is effective for fiscal years beginning after December with early adoption permitted. In October the FASB issued ASU - Financial Instruments – Credit Losses (Topic 326) , Derivatives and Hedging (Topic 815) and Leases (Topic 842) , which defers the effective date for public filers that are considered small reporting companies (“SRC”) as defined by the U.S. Securities and Exchange Commission (“SEC”) to fiscal years beginning after December including interim periods within those fiscal years. Since the Company was eligible to be an SRC based on its SRC determination as of November (which is the issuance date of ASU - in accordance with SEC regulations, the Company will adopt the standards for the year beginning January Adoption of the standard requires using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the effective date to align existing credit loss methodology with the new standard. The Company is evaluating the impact of this standard on its consolidated financial statements, including accounting policies, processes and systems and expects the standard will have a minor impact on its consolidated financial statements. |
