TSMC Trade Secret Theft Case Reaches Final Verdict, Lead Defendant Gets Decade in Prison

A high-profile trade secret case involving the core technology of chipmaking giant TSMC has concluded with final judicial rulings. Four former engineers were sentenced for illegally obtaining and leaking confidential data related to advanced process nodes like 2nm. The mastermind, Chen Liming, received a 10-year prison term, while another engineer, Chen Weijie, was sentenced to 6 years.

Case Overview: From Internal Collusion to Data Leakage

Court documents reveal that Chen Liming, formerly a yield engineer at TSMC's Fab 12, later joined the marketing department of a semiconductor equipment supplier. In an effort to secure equipment orders for his new employer from TSMC's advanced process lines, Chen resorted to illicit means.

He leveraged his past working relationships with former colleagues—Wu Bingjun, Ge Yiping, and Chen Weijie—who were still employed at TSMC. These engineers used their company-issued laptops to gain unauthorized access to confidential technical files.

  • Method of Operation: Sensitive data concerning 2nm and other processes was provided to Chen Liming either by photographing screen contents or directly transferring electronic files.
  • Individuals Involved: Besides Chen Liming, Wu Bingjun, Ge Yiping, and Chen Weijie all participated to varying degrees in the theft and transmission of data.

Legal Proceedings: Appeals Dismissed, Sentences Finalized

In the first trial, the court handed down varying sentences based on each individual's role and severity of actions. Chen Liming and Chen Weijie appealed the decisions, seeking reduced penalties. However, the Supreme Court recently dismissed their appeals, upholding the original sentences. Consequently, their prison terms are now finalized, and they will begin serving their sentences.

In contrast, their co-defendants, Wu Bingjun and Ge Yiping, did not appeal after the first trial, and prosecutors also refrained from appealing. Thus, their respective sentences of 3 years and 2 years have already taken effect.

Industry Implications: Internal Risks Within the Technology Fortress

This case transcends simple individual misconduct, serving as a stark reminder of a common vulnerability in cutting-edge technology sectors.

In capital and R&D-intensive industries like semiconductors, data related to advanced process development is a company's lifeline. TSMC's 2nm technology, as an industry leader, represents the future direction of chip manufacturing, possessing immense commercial and strategic value. This incident highlights that even with robust physical and cybersecurity measures, threats from "insiders" remain a persistent challenge.

Building more effective internal controls and cultural safeguards, while balancing technological collaboration with information segregation, is an ongoing imperative for all high-tech firms. This verdict undoubtedly sounds another alarm for the global industry on the critical importance of intellectual property protection and regulatory compliance.
