Company Overview and Historical Milestones
The foundation of STMicroelectronics lies in a bold 1987 merger that reshaped Europe's semiconductor landscape. By uniting Italy's SGS Microelettronica and France's Thomson Semiconducteurs, this cross-border collaboration created a new force in microelectronics. Both entities brought decades of technical expertise, with roots tracing back to Adriano Olivetti’s 1957 semiconductor venture.
Founding, Mergers, and Evolution
SGS Microelettronica emerged from a 1972 merger between ATES and Società Generale Semiconduttori. Across the Alps, France’s Thomson Semiconducteurs formed in 1982 through national consolidation, acquiring U.S. firm Mostek in 1985. These strategic moves laid the groundwork for the historic 1987 combination.
Under CEO Pasquale Pistorio, the newly formed SGS-THOMSON achieved rapid growth. Starting with $850 million in annual sales, the company climbed from 14th to top-tier status among global semiconductor suppliers within a decade.
Key Acquisitions and Global Growth
Strategic purchases accelerated technological diversification:
- Inmos (1989) - Advanced parallel processing
- Nortel’s semiconductor division (1994) - Telecom expertise
- VLSI-Vision (1999) - Imaging sensor leadership
Later acquisitions like Alcatel’s Microelectronics (2002) and Genesis Microchip (2007) strengthened wireless and video processing capabilities. These calculated moves transformed a regional manufacturer into a globally integrated technology provider.
