Key Takeaways:
A Taiwanese court sentenced a former Taiwan Semiconductor Manufacturing Co. engineer to 10 years in prison and fined a local unit of Japan's Tokyo Electron over the theft of sensitive chip technology, a landmark ruling that underscores the island's resolve to protect its core national industries. The case marks the first time Taiwan has invoked its National Security Act to prosecute intellectual property theft in the critical semiconductor sector.
"The court said Chen solicited confidential files from three other engineers, who were employed at TSMC at the time, to improve Tokyo Electron’s machinery," a court spokesperson said. The court found that Tokyo Electron failed to properly supervise Chen, noting that his internal performance reviews praised his ability to "leverage existing client resources" and obtain customer and competitor information.
The Intellectual Property and Commercial Court on Monday sentenced Chen Li-ming, a former TSMC engineer who had joined Tokyo Electron, to 10 years in prison. Three other engineers received sentences ranging from two to six years. A Tokyo Electron manager was given a 10-month suspended sentence for ordering the deletion of confidential TSMC files. Tokyo Electron’s Taiwan branch was fined NT$150 million (US$4.8 million), with NT$100 million payable to TSMC and NT$50 million to the state treasury. All defendants have the right to appeal.
This ruling sets a major precedent for intellectual property protection within Taiwan's vital semiconductor industry, which is increasingly viewed through a geopolitical lens. The verdict may act as a deterrent against future corporate espionage, yet it also exposes security vulnerabilities within the supply chains of the world's most advanced chipmaker. For investors, the case highlights the operational risks and the high stakes involved in protecting proprietary technology that underpins companies like Apple and Nvidia.
The investigation began in July of the previous year after TSMC's internal security systems flagged irregular data access. TSMC, which manufactures the world's most advanced chips for global giants, has consistently stated it will take aggressive action to defend its intellectual property and competitive edge. While Tokyo Electron is a key supplier of chip-making equipment to TSMC, not a direct competitor, the court found it benefited from the stolen trade secrets, which were used to refine its machinery to better serve TSMC.
According to the court spokesperson, TSMC confirmed that none of the leaked materials were passed on by Tokyo Electron to other parties. The specific terms of a settlement between the two companies remain confidential. In response to the indictment, Tokyo Electron had previously stated it was cooperating with authorities and has since pledged to strengthen its compliance and auditing practices.
The market reaction was muted, with shares of both companies rising on the day of the ruling. TSMC (2330.TW) closed up 3.7% in Taipei, while Tokyo Electron (8035.T) gained 3.0% in Tokyo, suggesting investors may have already priced in the legal dispute or are focusing more on the broader industry demand for advanced semiconductors. The verdict serves as a stark reminder of the constant threat of industrial espionage in the high-stakes semiconductor industry, where a technological edge can be worth billions of dollars.
