Taiwanese prosecutors have indicted Tokyo Electron, a key Japanese partner in the semiconductor industry, for its alleged role in a trade secrets case involving TSMC. The charges claim that Tokyo Electron failed to adequately prevent its employees from allegedly stealing proprietary information from the world's largest chipmaker. The indictment escalates a dispute between two critical players in the global chip supply chain. Prosecutors stated that while Tokyo Electron is not accused of using the stolen data, it did not implement sufficient preventive measures. They have asked a court to fine the Japanese company for failing in its oversight duties.
