TSMC 2nm Espionage Case Nears April 27 Verdict in First Taiwan National Security Act Semiconductor Prosecution

A Taiwan court is set to rule April 27 on the first semiconductor espionage case prosecuted under the National Security Act, charging former TSMC engineer Chen Li-ming and two others with stealing 2nm process technical data for Tokyo Electron. Prosecutors seek up to 14 years. The case has prompted Taiwan to plan further national security law revisions around semiconductor protection, and both the US and Taiwan now frame chip IP theft as a core national security threat.

Analysis
The April 27 verdict will set a precedent for how aggressively Taiwan applies national security law to semiconductor IP theft. The case involves Tokyo Electron, a Japanese firm, not a Chinese entity, complicating the narrative that chip espionage is solely a China problem. The outcome will likely influence how TSMC structures security protocols at its Arizona fab.
