CROLLES, FRANCE – December 11, 2025 – What was once hailed as a cornerstone of Europe's ambition to regain semiconductor manufacturing prowess – a multi-billion-euro collaboration between chip giants GlobalFoundries (NASDAQ: GFS) and STMicroelectronics (NYSE: STM) to build a next-generation automotive chip fab in Crolles, France – has reportedly stalled. Announced with much fanfare in 2022 and formalized in 2023, the joint venture aimed to significantly boost the production of specialized semiconductors critical for the burgeoning electric vehicle (EV), advanced driver-assistance systems (ADAS), and industrial Internet of Things (IoT) markets. However, as of early to mid-2025, the project has been put on hold, casting a shadow over Europe's strategic autonomy goals and raising questions about the agility of its industrial policy.
The initial collaboration promised a monumental step forward for the European semiconductor ecosystem. The planned facility was set to produce high-volume 300mm silicon wafers utilizing advanced Fully Depleted Silicon-On-Insulator (FD-SOI) technology, including GlobalFoundries' 22FDX and STMicroelectronics' roadmap down to 18nm. These chips are vital for the increasingly sophisticated demands of modern automobiles, which are rapidly transforming into software-defined, AI-driven machines. The stall, attributed to "market headwinds" and a re-evaluation of customer demand, underscores the volatile nature of the semiconductor industry and the complex challenges inherent in large-scale, government-backed manufacturing initiatives.
The Promise of Next-Gen Chips: FD-SOI and 18nm's Pivotal Role
The original vision for the Crolles fab centered on producing advanced semiconductors based on FD-SOI technology at process nodes down to 18nm. FD-SOI is a planar process technology that offers distinct advantages over traditional bulk CMOS, making it exceptionally well-suited for automotive and industrial applications. Its key benefits include significantly lower power consumption (up to 40% reduction), higher performance (up to 30% faster at constant power), and enhanced reliability and robustness against radiation errors – a critical feature for safety-critical ADAS and autonomous driving systems. This technology also provides superior analog and RF characteristics, crucial for 5G and millimeter-wave automotive radar systems.
Moving to 18nm process nodes with FD-SOI, as planned by STMicroelectronics in collaboration with Samsung Foundry, brings further advancements. This includes over a 50% improvement in the performance-to-power ratio compared to older 40nm embedded Non-Volatile Memory (eNVM) technology, expanded memory capacity with embedded Phase Change Memory (ePCM), and a threefold increase in digital peripheral densities. These technical leaps enable the integration of advanced features like AI accelerators, enhanced security, and high-performance computing capabilities directly onto the chip. STMicroelectronics' Stellar series of automotive MCUs, built on 18nm FD-SOI with ePCM, exemplify these benefits, targeting high-performance computing, security, and energy efficiency for complex in-vehicle applications.
The stalling of the Crolles fab, therefore, represents a delay in the planned significant increase in manufacturing capacity for these critical FD-SOI and 18nm process nodes. While both STMicroelectronics (NYSE: STM) and GlobalFoundries (NASDAQ: GFS) have existing facilities producing FD-SOI (e.g., GlobalFoundries in Dresden for 22nm FD-SOI and ST in Crolles for 28nm FD-SOI), the new joint fab was intended to accelerate the transition to sub-20nm FD-SOI on a larger scale. The absence of this new capacity will mean a slower ramp-up for these advanced technologies than originally envisioned, potentially impacting the pace at which cutting-edge ADAS, EV power management, and automotive IoT features can be widely adopted and supplied from a European base.
Corporate Shifts and Competitive Ripples in a Changing Market
The reported stall of the Crolles fab carries significant implications for both GlobalFoundries (NASDAQ: GFS) and STMicroelectronics (NYSE: STM), as well as the broader semiconductor and automotive industries. For GlobalFoundries, the delay postpones a major expansion of its 22FDX platform capacity in Europe, potentially slowing its market share gains in the region, especially as the company has reportedly been prioritizing investments in the United States. While a cautious approach to capital expenditure during a market downturn can be prudent, it also means a deferred opportunity to solidify its European presence.
STMicroelectronics (NYSE: STM), for its part, had viewed the Crolles fab as integral to its growth strategy, aiming for over $20 billion in revenue and strengthening the European FD-SOI ecosystem. The delay hinders its plans for rapid scaling of advanced node production for key markets. However, STMicroelectronics has demonstrated resilience, continuing to expand its existing Crolles facility independently and investing in other fabs like Agrate, Italy, for smart power and mixed-signal technologies. The company is also pursuing a "China-for-China" strategy and recently secured a €1 billion loan from the European Investment Bank (EIB) to boost European R&D and manufacturing. This indicates a diversified approach to mitigate the impact of the joint venture's halt.
For other chip manufacturers, the stalled project could momentarily reduce immediate competitive pressure in the FD-SOI market, allowing them to maintain existing market shares. However, the broader implication is a slower pace of new advanced capacity coming online in Europe, which, despite current weak demand for some chip types, could lead to renewed supply constraints if demand for FD-SOI technology rebounds sharply. The automotive industry, a primary beneficiary of the planned fab, faces prolonged reliance on geographically distant and vulnerable supply chains for these specialized components, undermining long-term goals of regional supply chain resilience. This sustained vulnerability could become critical if geopolitical tensions or global disruptions re-emerge.
Wider Significance: Europe's AI Ambitions and Historical Echoes
The stalling of the GlobalFoundries (NASDAQ: GFS) and STMicroelectronics (NYSE: STM) Crolles fab is more than just a corporate setback; it’s a critical indicator of the structural challenges facing Europe's ambition in the AI and semiconductor industries. The project was a cornerstone of the European Chips Act, a €43 billion initiative designed to double Europe's share of global semiconductor production to 20% by 2030 and enhance strategic autonomy. Its suspension highlights a significant weakness in European semiconductor policy: the rigidity of its funding mechanisms. Once funds are allocated, it becomes challenging to reallocate them without restarting complex approval processes, even when market conditions shift dramatically. This inflexibility risks hindering Europe's ability to achieve its strategic autonomy targets, leaving the continent vulnerable in critical technologies and reinforcing reliance on external supply chains.
The indirect impact on automotive AI development and deployment is particularly concerning. FD-SOI chips, which the Crolles fab was designed to produce, are crucial for power-efficient and resilient AI applications in ADAS, autonomous driving, and predictive maintenance. The absence of this anticipated large-scale output means that European automotive manufacturers and their AI development teams may face continued challenges in securing a stable supply of these specialized semiconductors. This could slow down their AI innovation cycles and increase vulnerability to global supply fluctuations, potentially widening the gap with leading AI development hubs in the US and Asia. The current global semiconductor market trend, where AI data centers dominate demand for high-performance chips, further intensifies competition for available capacity, indirectly affecting the automotive sector.
This situation also echoes historical struggles for Europe in the semiconductor industry. Past initiatives like the "Mega-Projekt" and JESSI in the 1980s faced similar setbacks due to withdrawals and budget cuts, ultimately failing to achieve their ambitious goals. These failures often stemmed from a lack of production scale, insufficient demand base, and fragmented national efforts. The Crolles delay, alongside other reported delays like Intel's (NASDAQ: INTC) Magdeburg fab, suggests a continuation of these historical challenges, raising concerns about Europe's capacity for agile and market-responsive industrial policy. While Europe has strengths in research and equipment (e.g., ASML (AMS: ASML)), its position in leading-edge manufacturing remains limited, risking a continued focus on mature technologies rather than leading-edge nodes crucial for advanced AI.
The Road Ahead: Future Developments and Persistent Challenges
Despite the current setback, the future of automotive semiconductors and AI remains one of explosive growth and transformative potential. In the near term (next 1-5 years), the automotive sector will see robust growth in semiconductor content, driven by advanced driver-assistance systems (ADAS), sophisticated in-cabin user experience (UX) features, and increasing electrification. The average semiconductor content per vehicle is projected to rise significantly, with EVs requiring substantially more chips than traditional internal combustion engine vehicles. AI will continue to be integrated into features like predictive maintenance, driver assistance, and voice-activated controls, with Level 2 and Level 2+ ADAS becoming standard.
Looking further ahead (beyond 5 years), experts predict that most vehicles will be AI-powered and software-defined by 2035, fundamentally reshaping the automotive landscape. Fully autonomous vehicles (Level 5) are expected to require a five-fold increase in the number of chips and a ten-fold increase in their cost per vehicle. This will necessitate advanced Systems-on-Chips (SoCs) capable of processing vast amounts of sensor data, with emerging technologies like chiplets being explored to address supply chain challenges. AI will evolve into integrated systems powering entire autonomous fleets, smart factories, and advanced vehicle diagnostics, enabling real-time decision-making, optimized route planning, and adaptive personalization.
However, Europe's ambition to achieve 20% of the global semiconductor market share by 2030 faces substantial hurdles. The Crolles fab stall exemplifies the rigidity of its policy mechanisms, where billions in allocated funds become locked and cannot be easily reallocated. Compounding this are a significant funding and investment gap compared to competitors like China, South Korea, and the United States, alongside bureaucratic delays, fragmentation, and a persistent talent shortage in skilled engineers and technicians. While STMicroelectronics (NYSE: STM) is moving forward with 18nm FD-SOI through alternative means, the stalled joint fab represents a significant setback for the planned large-scale capacity expansion and could lead to a slower overall rollout and potentially constrained availability of these advanced technologies for ADAS, EVs, and IoT applications in the longer term.
Comprehensive Wrap-Up: A Call for Agility
