On April 10 local time, stmicroelectronics (ST) disclosed that it would reshape its manufacturing layout, ensuring the long-term sustainability of ST as an IDM by adjusting its manufacturing layout and optimizing its cost structure.

In terms of manufacturing, ST focuses on investing in 300mm silicon wafer and 200mm silicon carbide wafer factories to achieve large-scale production and will enhance the production efficiency of 150mm and 200mm mature technologies. Introduce more AI and automation technologies into the processes of technology research and development, manufacturing, reliability and certification to enhance efficiency and focus on sustainability.

The 300mm wafer fab in Crolles, France, will become the core of digital products and plans to increase its production capacity to 14,000 wafers per week by 2027. The 300mm wafer fab in Agrate, Italy, will become a flagship manufacturing facility for smart power and mixed-signal technologies, with plans to increase its production capacity to 4,000 wafers per week by 2027. The Singapore wafer fab focuses on high-volume manufacturing with mature technologies and integrates global 150mm silicon wafer capabilities.

Factories such as Rousset and Tours in France and Kirkop in Malta will optimize their production capacity and functions according to market demand. Catania in Italy will continue to be a center of excellence for power and wide bandgap semiconductor devices. The development of the new silicon carbide park is proceeding as planned. The production of 200mm wafers will commence in the fourth quarter of 2025. Currently, resources for 150mm and EWS capabilities will be refocused on the production of 200mm silicon carbide and silicon power semiconductors. Including GaN-on-silicon.

With the advancement of advanced manufacturing, the role of employees will shift from traditional manual tasks to process control, automation and design. ST will optimize its global cost structure through a voluntary severance program. It is expected that up to 2,800 employees will voluntarily leave by 2027.
