Additional fine of T$25 million requested for Tokyo Electron's Taiwan unit on top of initial T$120 million fine sought in December.

NEWS BRIEF

Taiwanese prosecutors filed additional indictments against Tokyo Electron’s Taiwan unit and three defendants in a trade secrets theft case involving TSMC, seeking prison terms ranging from one to eight years and eight months. The new charges include two former TSMC employees and a former Tokyo Electron Taiwan employee, with prosecutors seeking an additional T$25 million fine on top of an initial T$120 million fine request, after discovering TSMC trade secrets still stored in the unit’s cloud storage.

WHAT HAPPENED

  • Prosecutors indicted Tokyo Electron’s Taiwan unit and three defendants including two former TSMC employees and one former Tokyo Electron employee.

  • Tokyo Electron is a major semiconductor equipment supplier, making the trade secrets case significant for the entire chip manufacturing ecosystem.
  • The charges include violations of Taiwan’s National Security Act, elevating the case beyond typical corporate espionage to national security concerns.
  • TSMC’s technological advantages and manufacturing processes are critical intellectual property worth billions and central to its market dominance.

IMPLICATIONS

  • The case could strain business relationships between Japanese equipment suppliers and Taiwanese chipmakers in the critical semiconductor supply chain.
