STMicroelectronics is a French-Italian multinational electronics and semiconductors manufacturer headquartered in Plan-les-Ouates nearby Geneva, Switzerland resulting from the merger of two government-owned semiconductor companies in 1987: "Thomson Semiconducteurs" of France and "SGS Microelettronica" of Italy. It is commonly called "ST", and it is Europe's largest semiconductor chip maker based on revenue. While STMicroelectronics corporate headquarters and the headquarters for EMEA region are based in Geneva, the holding company, STMicroelectronics N.V. is incorporated in the Netherlands.
