Samsung etching process recipes leaked to Lam Research Korea

Cointime update: Samsung Electronics has found that etching process recipes used in its semiconductor manufacturing were transferred to Lam Research’s Korean unit, the company’s internal investigation found. The unauthorized data transfers occurred multiple times and stemmed from non-compliant requests rather than a single incident, Samsung determined, treating the leak as a serious technology breach. Lam Research, which supplies etching and deposition equipment to Samsung’s chip lines, is permitted limited access to equipment data for performance optimization and maintenance.
