Taiwanese Court to Deliver Verdict in High-Profile TSMC Technology Theft Case

• March 31, 2026

A Taiwanese court is set to deliver a verdict on April 27 in one of the most notable intellectual property theft cases involving Taiwan Semiconductor Manufacturing Company (TSMC), the world’s leading contract chip maker. The case revolves around accusations that a former employee unlawfully obtained commercial secrets related to TSMC’s cutting-edge 2-nanometer semiconductor technology.

Legal Precedent in National Security Law Applied to Semiconductor Industry

This trial stands out as a significant legal precedent since it marks the first time Taiwan’s National Security Law has been applied within the context of semiconductor manufacturing. The deployment of this legislation underscores the strategic importance of the semiconductor sector to Taiwan’s national interests and highlights how technology theft cases are increasingly treated as matters of state security.

According to court documents, the accused individual, who once worked for TSMC, is facing potentially severe penalties. The maximum sentence could reach up to 20 years in prison, reflecting the gravity with which the Taiwanese judiciary is addressing breaches of trade secrets in the semiconductor industry. Details about the specific circumstances of the theft have not been publicly disclosed.

TSMC’s 2-nanometer process technology represents one of the most advanced manufacturing nodes in chip fabrication, positioning the company at the forefront of semiconductor innovation globally. As such, the protection of its proprietary technologies is critical not only for maintaining its competitive edge but also for safeguarding Taiwan’s position in the highly strategic semiconductor supply chain.

This case is one of three prominent lawsuits involving allegations of commercial secrets being stolen from TSMC, emphasizing the challenges that arise amid increasing global demand for cutting-edge chip technology and the attendant risks of corporate espionage.

The verdict will be closely watched by industry and legal observers alike, as it may influence how intellectual property theft cases are handled within Taiwan and possibly set guidelines for international standards on protecting technological advancements in the semiconductor sector.

Taiwan’s court will announce the verdict in a case involving stolen 2nm chip tech from TSMC, marking a first use of national security law in semiconductors.
