The Intellectual Property and Commercial Court (IPCC) has ordered one former employee and two current employees of Taiwan Semiconductor Manufacturing Co (TSMC) be detained and held incommunicado for allegedly stealing sensitive trade secrets involving the company’s advanced 2 nanometer process.
The ruling was handed down after the three suspects -- Chen Li-ming (陳力銘), an ex-TSMC engineer, Wu Ping- chun (吳秉駿) and Ko Yi-ping (戈一平), who currently worked as engineers for the chipmaker -- were referred to the IPCC yesterday morning.
A three-judge panel at the IPCC ruled that the three deleted their communications records after their conduct involving the alleged theft of TSMC’s advanced 2nm process was discovered, so there are reasonable fears they could continue to destroy evidence and collude with one another in making false statements.

The judges said that as the three suspects’ conduct potentially harmed national security and affected market competition, they should be detained to make sure the future court hearings proceed smoothly.
On Aug. 27, the Taiwan High Prosecutors Office Intellectual Property Branch indicted the three suspects for their roles in the alleged theft of trade secrets and violation of the National Security Act (國家安全法) by obtaining national core technology secrets for use abroad.
Prosecutors are seeking prison terms of 14 years, nine years, and seven years, respectively for Chen, Wu and Ko.
Chen is a former TSMC engineer working at Tokyo Electron Ltd. (TEL), a Japan-based supplier to TSMC. During the second half of 2024 and the first half of 2025, Chen asked Wu and Ko to provide trade secrets they had access to, under the guise of helping TEL secure more TSMC supplying contracts, according to prosecutors.
TSMC detected the irregularity and filed a lawsuit against the three in early July. Prosecutors launched searches and raids related to the case from July 25-28 and secured approval from the IPPC to detain them men the investigation.
The case was referred to the IPCC yesterday, and a hearing was needed to decide whether the three suspects could continue to be detained.
TEL said in late August that an internal investigation has so far found no evidence that confidential information about TSMC’s 2nm was leaked to a third party.
TSMC is developing the 2nm process, which is scheduled to start mass production in the second half of this year. Currently, the 3nm process is the latest technology for TSMC to begin commercial production.
The inspection equipment and data transmission system for new robotic dogs that Taipei is planning to use for sidewalk patrols were developed by a Taiwanese company, the city’s New Construction Office said today, dismissing concerns that the China-made robots could pose a security risk. The city is bringing in smart robotic dogs to help with sidewalk inspections, Taipei Deputy Mayor Lee Ssu-chuan (李四川) said on Facebook. Equipped with a panoramic surveillance system, the robots would be able to automatically flag problems and easily navigate narrow sidewalks, making inspections faster and more accurate, Lee said. By collecting more accurate data, they would help Taipei
TAKING STOCK: The USMC is rebuilding a once-abandoned airfield in Palau to support large-scale ground operations as China’s missile range grows, Naval News reported The US Marine Corps (USMC) is considering new sites for stockpiling equipment in the West Pacific to harden military supply chains and enhance mobility across the Indo-Pacific region, US-based Naval News reported on Saturday. The proposed sites in Palau — one of Taiwan’s diplomatic allies — and Australia would enable a “rapid standup of stored equipment within a year” of the program’s approval, the report said, citing documents published by the USMC last month. In Palau, the service is rebuilding a formerly abandoned World War II-era airfield and establishing ancillary structures to support large-scale ground operations “as China’s missile range and magazine

BETTER SERVICE QUALITY: From Nov. 10, tickets with reserved seats would only be valid for the date, train and route specified on the ticket, THSRC said Starting on Nov. 10, high-speed rail passengers with reserved seats would be required to exchange their tickets to board an earlier train. Passengers with reserved seats on a specific train are currently allowed to board earlier trains on the same day and sit in non-reserved cars, but as this is happening increasingly often, and affecting quality of travel and ticket sales, Taiwan High-Speed Rail Corp (THSRC) announced that it would be canceling the policy on Nov. 10. It is one of several new measures launched by THSRC chairman Shih Che (史哲) to improve the quality of service, it said. The company also said
