Nano 2030 is France’s semiconductor R&D investment program, the successor to Nano 2022 and France’s primary mechanism for maintaining technological leadership in microelectronics while the 7-plus billion euro Crolles fab expansion proceeds. With approximately 5 billion euros in combined national and European funding, Nano 2030 is simultaneously a research program, an industrial investment, and a geopolitical instrument for European semiconductor sovereignty.

Strategic Context: Why Semiconductors Are France 2030’s Highest-Stakes Sector

France’s semiconductor ambition is defined by two strategic imperatives that occasionally create tension. The first is research leadership: France, through CEA-LETI in Grenoble, holds a globally recognized position in semiconductor research, specifically in 300mm wafer technology, silicon photonics, advanced packaging, and GaN/SiC power electronics. Maintaining this research edge requires continuous investment in equipment, talent, and facilities that advance faster than Moore’s Law.

The second is manufacturing sovereignty: The COVID-19 pandemic, the 2020-2022 chip shortage, and the US-China semiconductor war demonstrated that Europe’s dependence on Asian and American fabs for advanced chips was a strategic vulnerability. The European Chips Act’s 43 billion euro framework and France’s Nano 2030 are the response, an attempt to rebuild European manufacturing capacity in advanced nodes.

Nano 2030: Program Architecture

Nano 2030 is technically a European consortium program involving seven European countries (France, Germany, Netherlands, Belgium, Italy, Spain, Czech Republic) but with France, through CEA-LETI and STMicroelectronics, in the leadership position.

Total Program Scale: Approximately 5 billion euros over 2021-2030. The French national contribution through France 2030 is approximately 2.2 billion euros, the European Commission through Chips Act IPCEI Microelectronics provides approximately 1.8 billion euros, and participating company co-investment accounts for approximately 1 billion euros.

Research Focus Areas:

Advanced CMOS and Next-Generation Nodes (1.5 billion euros): The most critical investment area, targeting 2nm and below node architectures including Gate-All-Around (GAA) transistors, 3D chip stacking, and CFET structures. CEA-LETI is the research lead, with process development in its 300mm Grenoble facility and co-development with STMicro’s Crolles line.

Silicon Photonics (600 million euros): France has a strong claim to global leadership in silicon photonics, the integration of optical functions on silicon chips for data communication, LiDAR, and sensing applications. CEA-LETI’s silicon photonics platform is among the world’s most advanced, hosting development work for hyperscaler data center interconnects and French LiDAR startups.

GaN and SiC Power Electronics (500 million euros): Wide-bandgap semiconductor materials are critical for the EV revolution, renewable energy power conversion, and industrial motor drives. STMicroelectronics is Europe’s leading SiC device manufacturer, and Nano 2030 funds both manufacturing scale-up and next-generation device research.

Advanced Packaging and 3D Integration (400 million euros): Modern semiconductor performance no longer comes solely from transistor shrinking. Advanced packaging, including chiplets, fan-out wafer-level packaging, and Through-Silicon Via integration, enables multiple dies to communicate with low latency and high bandwidth.

Neuromorphic and In-Memory Computing (250 million euros): Beyond von Neumann architectures. Neuromorphic chips process information in fundamentally different ways, closer to biological neural networks, enabling extreme energy efficiency for AI inference workloads. CEA-LETI’s NEUROTOP program develops phase-change memory synaptic devices.

Quantum-Classical Integration (200 million euros): At the intersection of Nano 2030 and the Plan Quantique: developing the cryogenic CMOS control chips that quantum processors require, and exploring quantum-classical hybrid computing architectures.

The Crolles Ecosystem: France’s Semiconductor Heartland

The geographic heart of France’s semiconductor strategy is the Crolles research and manufacturing campus 25 kilometers northeast of Grenoble. Crolles concentrates STMicroelectronics Crolles 300, the existing 300mm production fab producing STMicro’s most advanced process nodes including 28nm, 18nm, and 12nm FD-SOI for RF applications; GlobalFoundries Crolles, a planned joint expansion of the STMicro fab under a 50-50 joint venture targeted at 22nm FD-SOI for automotive, industrial, and IoT applications; CEA-LETI, the 300mm research fab directly adjacent to STMicro employing 2,700 researchers; and Soitec Bernin, the global leader in SOI wafer manufacturing supplying the specialized substrates that enable FD-SOI technology.

This co-location creates a unique innovation cluster. Research insights at CEA-LETI flow to STMicro production within months versus years for research-to-fab transfers at non-collocated institutions, and Soitec’s materials innovations are developed in direct partnership with LETI before commercialization.

The STMicro-GlobalFoundries Joint Venture: 7.5 Billion Euro Investment

The centerpiece of France’s semiconductor manufacturing ambition is the joint fab expansion at Crolles by STMicroelectronics and GlobalFoundries, a 7.5 billion euro total investment of which approximately 2.9 billion comes from combined French and European public support.

Public support breakdown: French state through France 2030 and Nano 2030 approximately 1.6 billion euros in grants and tax credits, European Chips Act co-funding approximately 900 million euros, and regional support from Auvergne-Rhone-Alpes approximately 400 million euros.

The new facility will produce 22nm FD-SOI wafers at 620,000 units per year at full capacity, primarily for automotive, industrial IoT, and smart devices applications. The automotive and industrial market segments were the segments most disrupted by the chip shortage of 2020-2022, and they are segments where France’s FD-SOI technology holds genuine performance advantages over pure-play foundries producing at comparable nodes.

Employment impact: The new facility will employ approximately 1,000 additional engineers and technicians at full run rate. Groundbreaking occurred in 2023, with commercial production beginning in 2027.

Soitec: The Substrate Champion

No discussion of Nano 2030 is complete without Soitec, the Grenoble company that manufactures SOI (Silicon-On-Insulator) wafers. Soitec holds over 80% of the global SOI market. Its wafers are the necessary foundation for every FD-SOI chip produced at Crolles and at Samsung’s FD-SOI fab in South Korea. This supply chain position gives Soitec extraordinary strategic value: whoever controls SOI wafer supply controls a bottleneck for a substantial portion of global mobile and IoT chip production.

France 2030 has supported Soitec’s capacity expansion at its Bernin facility and its new production line in Poitiers opened 2022, adding approximately 40% to Soitec’s global SOI capacity.

European Chips Act Integration

Nano 2030 is deeply integrated with the European Chips Act which came into force in September 2023. France’s investments are recognized as contributing to the ECA’s goal of doubling Europe’s semiconductor market share from 10% to 20% of global production by 2030.

The practical implications: the STMicro-GlobalFoundries Crolles expansion qualifies as a First-of-a-Kind facility under ECA criteria, unlocking European co-funding at higher rates. French companies in the Nano 2030 ecosystem have priority access to the ECA’s 6.2 billion euro Chips Fund for scale-up investments. The ECA integration adds approximately 30 to 40% to the effective public support available for qualifying French semiconductor investments, reducing the private capital hurdle for large fab investments.

France’s semiconductor sovereignty strategy thus rests on three mutually reinforcing pillars: CEA-LETI’s world-class research capabilities, STMicro’s manufacturing scale and FD-SOI technology leadership, and Soitec’s unassailable position in the SOI wafer supply chain. Nano 2030 is the investment framework that maintains and strengthens all three simultaneously.
