Production is expected to start in 2023, enabling a balanced supply of SiC substrate between internal and merchant supply.
The SiC substrate manufacturing facility, built at ST’s Catania site in Italy alongside the existing SiC device manufacturing facility, will be a first of a kind in Europe for the production in volume of 150mm SiC epitaxial substrates, integrating all steps in the production flow. ST is committed to develop 200mm wafers in the next future.
This project is a key step in advancing ST’s vertical integration strategy for its SiC business. The investment of €730 million over five years will be supported financially by the State of Italy in the framework of the National Recovery and Resilience Plan and it will create around 700 direct additional jobs at full build-out.
“ST is transforming its global manufacturing operations, with additional capacity in 300mm manufacturing and a strong focus on wide bandgap semiconductors to support its $20+B revenue ambition. We are expanding our operations in Catania, the centre of our power semiconductor expertise and where we already have integrated research, development and manufacturing of SiC with strong collaboration with Italian research entities, universities and suppliers” said Jean-Marc Chery, President and Chief Executive Officer of STMicroelectronics. “This new facility will be key to our vertical integration in SiC, reinforcing our SiC substrate supply as we further ramp up volumes to support our automotive and industrial customers in their shift to electrification and higher efficiency”.
Catania has long been an important site for innovation for ST and is the home of its largest SiC R&D and manufacturing operations.
ST’s STPOWER SiC products are currently manufactured in its fabs in Catania and Ang Mo Kio (Singapore). Assembly and test are done at back-end sites in Shenzhen (China) and Bouskoura (Morocco).
According to ST, the investment in this SiC substrate manufacturing facility is a significant milestone on ST’s path towards reaching 40% internal substrate sourcing by 2024.
