History

Perspective
In 1957, Mario Tchou, an engineer from Olivetti, convinced Adriano Olivetti to found an Italian electronic manufacturing company for production of solid-state electronic devices. Olivetti sent his son Roberto Olivetti and Mario Tchou to negotiate with Virgilio Floriani, president of Telettra, to establish a joint venture. Within the same year, Olivetti and Telettra founded Società Generale Semiconduttori (SGS).[2] One of the reasons for SGS's foundation was the need of parts (diodes and transistors in particular) for Elea, a mainframe that was being developed by Olivetti. The headquarters of the company was located in Agrate Brianza.[3]
In 1960, Fairchild Semiconductor acquired one third of the company and a joint venture called SGS-Fairchild was formed. That gave SGS access to Fairchild's newly invented planar manufacturing technology.[4] The partnership ended in 1968 and Fairchild sold its SGS stocks to IRI-STET, predecessor of TIM.
In December 1971, SGS merged with an Italian semiconductor company named ATES and forms SGS-ATES. On 23 April 1985, the company changes its name to SGS Microelettronica. 2 years later, SGS Microelettronica merged with Thomson Semiconductors to form SGS-Thomson, which later became STMicroelectronics in 1998.[3]
