STMicroelectronics Expands SiC Wafer Production Capacity in Italy for Automotive Sector
STMicroelectronics has announced a significant expansion of its silicon carbide (SiC) wafer manufacturing capabilities at its Catania, Italy facility. This move directly addresses the surging demand for automotive-grade SiC devices, crucial for electric vehicle (EV) powertrains and industrial applications.
STMicroelectronics (ST) today announced a substantial investment to expand its 8-inch silicon carbide (SiC) wafer production capacity at its dedicated facility in Catania, Italy. This strategic expansion is primarily aimed at fortifying ST's position as a leading supplier of SiC power semiconductors, a critical component for the rapidly growing electric vehicle (EV) market and various high-power industrial applications. The company anticipates the new capacity to begin contributing to overall supply by late 2027, with full ramp-up projected for early 2029.
The investment underscores the intensifying competition among semiconductor manufacturers to secure long-term supply agreements for automotive-grade SiC. As EVs increasingly dominate vehicle production roadmaps, the demand for high-efficiency, high-power-density SiC devices for inverters and on-board chargers has skyrocketed. This expansion by STMicroelectronics is a direct response to customer commitments and the need to mitigate potential supply bottlenecks that could impact EV production schedules globally.
Procurement engineers should note that while this long-term capacity increase is positive, it does not immediately alleviate current tight supply conditions for SiC devices. Lead times for specific automotive-grade SiC parts may remain extended through 2027. Companies reliant on STMicroelectronics' SiC offerings are advised to review their long-term forecasts and engage proactively with their suppliers to ensure allocation in upcoming production cycles. The ramp-up process for advanced SiC wafer manufacturing is complex and capital-intensive, requiring significant time for qualification and yield optimization.
This expansion further solidifies Europe's role in the global SiC supply chain, contributing to regional self-sufficiency for critical automotive components. The Catania site is a recognized center of excellence for power semiconductors, and this additional investment is expected to create new high-skilled jobs while reinforcing manufacturing resilience within the European Union. The move aligns with broader industry efforts to diversify and localize semiconductor production.
