## Tokyo Electron Subsidiary Fined, Executives Jailed in Taiwan Trade Secrets Case Involving TSMC Technology
A Tokyo Electron subsidiary and several of its executives have been penalized in Taiwan following one of the island's most closely watched cases involving alleged theft of semiconductor technology belonging to TSMC, the world's largest contract chipmaker. The rulings mark a significant development in Taiwan's efforts to enforce its National Security Act against unauthorized transfers of core technologies, particularly in the strategically sensitive semiconductor sector.

Prosecutors in Hsinchu pursued charges against the Japanese company's local subsidiary, alleging that employees acquired or exploited TSMC proprietary information related to advanced chip manufacturing processes. Court documents indicate the subsidiary received a financial penalty while individuals connected to the operation were sentenced to prison terms. The case drew sustained attention from Taiwan's Ministry of Justice and its INVESTIGATION BUREAU, which coordinated with prosecutors throughout the lengthy probe.

Taiwan has intensified scrutiny of trade secret misappropriation since enacting amendments to its Trade Secrets Act and expanding the application of national security provisions to cover critical technologies. The prosecution of a Japanese firm—rather than a domestic entity—underscores the broader enforcement reach authorities are willing to exercise. TSMC, which supplies chips to Apple, Nvidia, and other major technology companies, has been a persistent target of industrial espionage attempts given its dominance in advanced semiconductor production. The case signals continued legal risks for firms and individuals involved in unauthorized acquisition or transfer of semiconductor intellectual property across the Taiwan Strait and beyond.
