Commitments and Contingencies Disclosure [Text Block]	8. COMMITMENTS AND CONTINGENCIES *Strategic Partnership with Advantest* See Note 15, “Strategic Partnership Agreement with Advantest and Related Party Transactions” for the discussion about the Company’s commitments under the strategic partnership with Advantest. *Operating Leases* See Note 6, “Leases” for the discussion about the Company’s lease commitments. *Indemnifications* The Company generally provides a warranty to its customers that its software will perform substantially in accordance with documented specifications typically for a period of 90 days following delivery of its products. The Company also indemnifies certain customers from third-party claims of IP infringement relating to the use of its products. Historically, costs related to these guarantees have not been significant. The Company is unable to estimate the maximum potential impact of these guarantees on its future results of operations. The Company’s standard product warranty terms for the sale of its DirectScan system product generally include post-sales support and repairs or replacement of a product at no additional charge for a contractually agreed period of time. The standard warranty reserve is based on estimated total expected costs to fulfill our warranty obligation based on best available information as of the reporting date. The standard warranty reserve was nil and immaterial as of December 31, 2025 and 2024, respectively. *Purchase Obligations* The Company has purchase obligations with certain suppliers for the purchase of goods and services entered in the ordinary course of business. As of December 31, 2025, total outstanding purchase obligations were $65.3 million, the majority of which are due within the next 2 years. *Indemnification of Officers and Directors* As permitted by the Delaware general corporation law, the Company has included a provision in its certificate of incorporation to eliminate the personal liability of its officers and directors for monetary damages for breach or alleged breach of their fiduciary duties as officers or directors, other than in cases of fraud or other willful misconduct. In addition, the Bylaws of the Company provide that the Company is required to indemnify its officers and directors even when indemnification would otherwise be discretionary, and the Company is required to advance expenses to its officers and directors as incurred in connection with proceedings against them for which they may be indemnified. The Company has entered into indemnification agreements with its officers and directors containing provisions that are in some respects broader than the specific indemnification provisions contained in the Delaware general corporation law. The indemnification agreements require the Company to indemnify its officers and directors against liabilities that may arise by reason of their status or service as officers and directors other than for liabilities arising from willful misconduct of a culpable nature, to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified, and to obtain directors’ and officers’ insurance if available on reasonable terms. The Company has obtained directors’ and officers’ liability insurance in amounts comparable to other companies of the Company’s size and in the Company’s industry. Since a maximum obligation of the Company is not explicitly stated in the Company’s Bylaws or in its indemnification agreements and will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the obligations cannot be reasonably estimated. *Litigation* From time to time, the Company is subject to various claims and legal proceedings that arise in the ordinary course of business. As of December 31, 2025, except as disclosed below, the Company was not party to any material legal proceedings. On May 6, 2020, the Company initiated an arbitration proceeding with the Hong Kong International Arbitration Center (the “Tribunal”) against SMIC New Technology Research & Development (Shanghai) Corporation (“SMIC”) due to SMIC’s failure to pay fees due to the Company under a series of contracts. The Company sought to recover the unpaid fees, a declaration requiring SMIC to pay fees under the contracts in the future (or a lump sum payment to end the contract), and costs associated with bringing the arbitration proceeding. SMIC denied liability and an arbitration hearing was held in February 2023. On November 12, 2025, the Tribunal issued a confidential arbitration award (the “Award”), which is in favor of the Company. The Company is separately pursuing an award as to costs. No payments under the Award have been received by the Company to date and in February 2026, SMIC filed an application with the High Court of Hong Kong seeking to set the Award aside. The Company believes the set aside application is without merit and intends to defend it, and is pursuing judicial enforcement of the Award. There can be no assurances that the Company will receive all or any part of the Award. Accordingly, no amounts have been recognized in connection with the Award as of December 31, 2025.
