The Intellectual Property and Commercial Court yesterday ruled that a Taiwan Semiconductor Manufacturing Co (TSMC) employee be detained incommunicado for allegedly stealing the company’s 14-nanometer (nm) trade secrets.
The suspect, Chen Wei-chieh (陳韋傑), was indicted on Monday on charges of reproducing trade secrets relating to national core key technologies without authorization under the National Security Act (國家安全法).
Chen is suspected of the alleged offenses after investigators reviewed the evidence, including witness testimony, text message records, his nondisclosure agreement and employee monitoring system records provided by TSMC.

The court said that Chen’s statements regarding his actions were inconsistent and evasive, and that he replaced his personal mobile phone and office computer after learning that codefendant Chen Li-ming (陳力銘) was under investigation.
The court said that discarding or destroying devices suspected of being used to reproduce and transmit trade secrets could constitute destruction of evidence, indicating a risk of evidence tampering and collusion.
Moreover, the crime that he was allegedly involved in not only damaged TSMC, but also national security, industrial competitiveness and economic development, the court added.
The case came to light while the High Prosecutors' Office’s Intellectual Property Branch was investigating the alleged theft of TSMC trade secrets related to its 2nm technology.
The probe centered on former TSMC engineer Chen Li-ming, who was working at Tokyo Electron Taiwan Ltd and is suspected of transmitting the secrets to the company.
During the investigation, prosecutors discovered that Tokyo Electron Taiwan’s cloud storage also contained trade secrets linked to TSMC’s 14nm technology.
When confronted with the evidence, Chen Li-ming identified Chen Wei-chieh as being involved in the case, prosecutors said.
Chen Li-ming and two other suspects in the 2nm technology theft case have also been detained.
Meanwhile, Tokyo Electron Taiwan has also been indicted in both cases for failing to properly supervise Chen Li-ming.

Taiwan’s armed forces have established response protocols for a wide range of sudden contingencies, including the “Wan Chun Plan” to protect the head of state, the Ministry of Defense (MND) said today. After US President Donald Trump on Saturday launched a series of airstrikes in Venezuela and kidnapped Venezuelan President Nicolas Maduro, concerns have been raised as to whether China would launch a similar “decapitation strike” on Taiwan. The armed forces regularly coordinate with relevant agencies and practice drills to ensure preparedness for a wide range of scenarios, Vice Minister of National Defense Hsu Szu-chien (徐斯儉) told reporters before a
EVA Airways on Saturday said that it had suspended a pilot and opened an investigation after he allegedly lost his temper and punched the first officer several times as their plane was taxiing before takeoff at Los Angeles International Airport.

Japanese Councilor Hei Seki (石平) on Wednesday said that he plans to visit Taiwan, saying that would “prove that Taiwan is an independent country and does not belong to China.” Seki, a member of the Japan Innovation Party, was born in Chengdu in China’s Sichuan Province and became a naturalized Japanese in 2007. He was elected to the House of Concilors last year. His views on the Chinese Communist Party (CCP) — espoused in a series of books on politics and history — prompted Beijing to sanction him, including barring Seki from traveling to China. Seki wrote on X that he intends
