Overview
GlobalFoundries is one of the world’s largest semiconductor contract manufacturers — a US-headquartered wafer foundry (NASDAQ: GFS) that produces chips for customers including AMD, Qualcomm, Samsung, and hundreds of fabless semiconductor companies. In France, GlobalFoundries operates as a major co-investor in the Crolles semiconductor cluster near Grenoble, where it has partnered with STMicroelectronics for a €7.5 billion joint expansion of France’s most advanced chip manufacturing site.
The Crolles joint investment — officially announced in 2022 and supported by approximately €5.7 billion in public funding from France (via France 2030) and the EU (via European Chips Act) — will expand the Crolles 6 facility from its current capacity to produce additional 300mm wafers using FD-SOI (Fully Depleted Silicon-On-Insulator) technology and RF (Radio Frequency) processes. This expansion is not building leading-edge chips competing with TSMC’s 3nm technology — it is building specialized, mature-node chips for automotive, IoT, and communications applications where FD-SOI technology has specific advantages.
GlobalFoundries’ Crolles presence makes it one of the largest employers in the Auvergne-Rhône-Alpes region’s semiconductor ecosystem, with approximately 7,500 employees at Crolles 6. The company’s technology focus — FD-SOI, SiGe BiCMOS, GaN RF — serves markets that France 2030 designates as strategic: automotive semiconductors (for ADAS and EV powertrains), IoT connectivity chips, and 5G/6G communications infrastructure.
France 2030 Funding & Projects
Crolles Joint Expansion (France 2030’s flagship semiconductor investment): The €7.5 billion Crolles joint investment is France 2030’s single largest semiconductor commitment, and among the most significant French industrial investments of the decade:
- Total investment: €7.5 billion (2022-2030 timeframe)
- Public funding: ~€5.7 billion (France 2030 via Bpifrance, French state, and EU Chips Act funding through European Commission state aid approval)
- Private investment: ~€1.8 billion (STMicroelectronics + GlobalFoundries proportional contribution)
- Scope: Expansion of Crolles 6 cleanroom capacity; wafer production volume doubling; potential new Crolles 7 facility construction
The investment timeline targets:
- 2024-2025: Detailed planning, environmental impact assessment, permitting
- 2026: Groundbreaking for new capacity
- 2028-2030: New cleanroom operational, additional wafer capacity online
European Chips Act (Chips Act) connection: France 2030’s semiconductor investment is co-financed with the EU Chips Act, which allocates €43 billion across Europe to strengthen semiconductor manufacturing capacity. The Crolles expansion qualifies under the “First-of-a-kind facility” designation in the European Chips Act — enabling higher public subsidy rates than standard state aid rules would permit. France’s successful Chips Act application is among the first major national implementations of the regulation.
FD-SOI technology leadership: GlobalFoundries and STMicro’s Crolles site is the world’s primary production hub for FD-SOI technology — a semiconductor platform where Silicon-On-Insulator wafers enable chips with lower power consumption and better RF performance than standard bulk silicon, at manufacturing nodes between 28nm and 12nm. This technology is not competing with TSMC’s leading-edge for high-performance computing — it is the platform for:
- Automotive radar (millimeter-wave chips for ADAS)
- IoT chips (ultra-low power sensors and processors)
- 5G millimeter-wave chips (for base station and handset RF front ends)
- Industrial microcontrollers
France 2030 specifically identifies automotive semiconductors and IoT as strategic technology priorities — sectors where FD-SOI’s advantages are most pronounced and where European demand exists today.
IPCEI Microelectronics: GlobalFoundries/Crolles is part of IPCEI ME/CT (Microelectronics and Communication Technologies) — the EU-coordinated semiconductor investment program. France 2030 funds France’s national contribution to IPCEI ME/CT, and Crolles is France’s designated site for the wafer manufacturing component of the IPCEI.
Key Technology & Products
FD-SOI (Fully Depleted Silicon-On-Insulator): The premier technology platform at Crolles. FD-SOI wafers use an ultra-thin silicon layer on an insulating oxide layer, eliminating the need for the doped “wells” that standard bulk silicon CMOS requires. This simplifies manufacturing, reduces power consumption (by eliminating leakage current pathways), and enables “back-bias tuning” — applying voltage to the substrate to dynamically trade off speed vs. power consumption. At 22nm and 12nm nodes, FD-SOI is competitive with or superior to comparable FinFET processes for IoT and automotive applications.
GF Passport RF and mmWave: GlobalFoundries’ specialty RF process technologies (based on SiGe heterojunction bipolar transistors and CMOS RF) enable chips for wireless communications applications: 4G/5G modems, Wi-Fi, radar sensors, and emerging 6G research applications. Crolles produces GF’s European production of these RF technologies.
Automotive-grade processes: Crolles is qualified for AEC-Q100 automotive semiconductor manufacturing — the industry standard for automotive component reliability. As European automakers (Renault, Stellantis, Valeo, Continental) seek European-sourced automotive semiconductors (reducing supply chain vulnerability post-COVID chip shortage), Crolles is positioned as France 2030’s “sovereign automotive chip” facility.
STMicro+GF Technology Partnership: The joint manufacturing relationship is not arms-length customer-supplier: STMicro and GlobalFoundries have deep technology co-development agreements, sharing process technology development costs and aligning technology roadmaps. This integration creates manufacturing efficiencies and technology advantages that neither company would achieve independently.
Crolles Semiconductor Cluster
Crolles (in the Grésivaudan valley between Grenoble and Chambéry) is France’s silicon valley equivalent for semiconductor manufacturing:
- STMicroelectronics Crolles 1&2: Existing wafer fabs (200mm and 300mm)
- GlobalFoundries Crolles 6: Joint venture with STMicro, 300mm, primary FD-SOI production
- Potential Crolles 7: New facility under France 2030 expansion planning
- CEA-Leti (adjacent): Europe’s largest semiconductor research laboratory, directly adjacent to the commercial fabs — providing research-to-manufacturing technology transfer pipeline
- STMicro/GF R&D center: Joint development organization at Crolles
- Supply ecosystem: Photomask suppliers, specialty chemicals, equipment maintenance companies clustered around the fabs
The Crolles cluster’s unique advantage: CEA-Leti’s research adjacency. Unlike most commercial semiconductor fabs that must license technology from external sources, Crolles operates in daily proximity to one of Europe’s best-resourced semiconductor research organizations. This reduces technology transfer time and allows commercial production of research advances at manufacturing scale.
Strategic Context: Why FD-SOI, Not Leading-Edge
France 2030’s semiconductor strategy has sometimes been criticized for not targeting TSMC-equivalent leading-edge (3nm, 2nm) chip manufacturing. The strategic rationale for the FD-SOI/automotive focus:
Addressable market: European demand for 3nm chips is dominated by Apple, Qualcomm, and Nvidia — American companies that primarily source from TSMC Taiwan. There is no realistic near-term scenario where European demand justifies a €50B+ leading-edge fab investment.
European competitive advantage: FD-SOI technology is where STMicro and GlobalFoundries have genuine IP and manufacturing leadership. Building on proven advantage is more credible than attempting to match TSMC’s leading-edge from zero.
Automotive and IoT priority: European automotive, industrial, and IoT chip demand at 28-12nm nodes is massive and growing — and these customers specifically want European, non-China-dependent supply chains. FD-SOI directly addresses this demand.
CHIPS Act feasibility: The European Chips Act’s “first-of-a-kind” designation requires that the facility use technology not currently in commercial production at scale in Europe. Crolles expansion of existing FD-SOI capacity qualifies under this definition.

Investor Perspective
GlobalFoundries (GFS) is publicly listed on NASDAQ — the most direct way to invest in France 2030’s semiconductor manufacturing commitment. The Crolles expansion de-risks GFS’s European manufacturing capacity with ~€2-3B in public subsidy support, significantly improving the return on invested capital for GFS’s French operations.
Key GFS investment metrics:
- P/E: 25-35x forward earnings
- Revenue growth: 5-10%/year as automotive and IoT demand grows
- France 2030 impact: Crolles expansion adds ~10-15% to GFS capacity at subsidized cost; improved ROI for French operations
- Risk: Leading-edge customers (like AMD) continuing migration toward TSMC; GFS is not competitive at 5nm and below
For semiconductor-focused France 2030 investors, the GFS-STMicro Crolles investment is best accessed through STMicroelectronics (STM, listed on NYSE and Euronext) — which is a French company, CAC40 member, and has even larger Crolles exposure than GFS.
