STMicroelectronics

STMicroelectronics is a Franco-Italian semiconductor company jointly owned by French and Italian governments through their respective holding companies, making it one of Europe's most explicitly state-backed chip manufacturers. Founded in 1987 through the merger of SGS Microelettronica (Italy) and Thomson Semiconducteurs (France), it is headquartered in Geneva and employs around 50,000 people globally. ST specialises in microcontrollers, automotive chips, and power semiconductors, components critical for electric vehicles, industrial automation, and defence electronics. It is the largest European-owned chip company by revenue.

ST's Crolles facility in France was at the centre of Europe's advanced chip manufacturing ambitions until GlobalFoundries, its production partner at the site, suspended the expansion in 2025. The Crolles suspension significantly weakened France's position in the EU Chips Act goal of doubling Europe's share of global semiconductor production to 20% by 2030. STMicroelectronics received an Integrated Production Facility designation from the European Commission under the Chips Act, confirming EU recognition of its strategic role, but the economics of advancing to sub-7nm production without a partner remain challenging.

ST is a bellwether for Europe's broader industrial semiconductor ambition. Its existing production nodes (40nm-130nm) serve automotive and industrial customers who are not chasing the cutting-edge nodes that dominate headlines. This mid-range production is highly profitable and serves critical European supply chains, but it does not address Europe's near-total dependence on Asia for the most advanced chips used in AI, server, and consumer electronics. Whether ST can credibly invest in more advanced nodes without government subsidies at the scale provided to TSMC in the US and Asia remains an open question.
