STM manufactures their first 200mm wafer.

They seem to imply that they will have 200mm production by 2024 but don't say it explicitly.

STMicroelectronics Manufactures First 200mm Silicon Carbide Wafers
Transition to 200m wafers marks milestone in capacity build-up to support automotive and industrial markets in the electrification of their systems and products

Geneva, Switzerland, July 27, 2021 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, today announced it has manufactured the first 200mm (8-inch) Silicon-Carbide (SiC) bulk wafers for prototyping next-generation power devices from its facility in Norrköping, Sweden. The transition to 200mm SiC wafers marks an important milestone in the capacity build-up for ST’s customer programs in automotive and industrial sectors and will consolidate ST’s lead in the disruptive semiconductor technology that allows for smaller, lighter, and more efficient power electronics with a lower total cost of ownership.

Among the first in the world, ST’s initial 200mm SiC wafers are also very high quality, with minimal yield-impacting and crystal-dislocation defects. The low defectivity has been achieved by building on the excellent know-how and expertise in SiC ingot growth technology developed by STMicroelectronics Silicon Carbide A.B. (formerly Norstel A.B., which ST acquired in 2019). In addition to meeting the quality challenge, the transition to 200mm SiC substrates requires a step forward in manufacturing equipment and the overall support ecosystem performance. ST, in collaboration with technology partners covering the entire supply chain, is developing its own 200mm SiC manufacturing equipment and processes.

ST currently manufactures its leading-edge, high-volume STPOWER SiC products on two 150mm wafer lines in its fabs in Catania (Italy) and Ang Mo Kio (Singapore) and performs assembly and test at its back-end sites in Shenzhen (China) and Bouskoura (Morocco). This milestone comes as part of the Company’s planned move to more advanced, cost-efficient 200mm SiC volume production. This transition is within the Company’s ongoing plan to build a new SiC substrate plant and source over 40% of its SiC substrates internally by 2024.

“The transition to 200mm SiC wafers will bring substantial advantages to our automotive and industrial customers as they accelerate the transition towards electrification of their systems and products”, said Marco Monti, President Automotive and Discrete Group, STMicroelectronics. “It is important in driving economies of scale as product volumes ramp. Building robust know-how in our internal SiC ecosystem across the full manufacturing chain, from high-quality SiC substrates to large-scale front- and back-end production, boosts our flexibility and allows us to better control the improvement of yield and quality of the wafers.”

Notes to Editors

Silicon Carbide is a compound semiconductor material with intrinsic properties providing superior performance and efficiency over silicon in key, high-growth power applications for electro-mobility (e-mobility) and industrial processes, among others. ST’s leadership in SiC is the result of 25 years of focus and commitment in R&D with more than 70 patents. The disruptive technology allows for more efficient power conversion, lighter and more compact designs, and overall system-design cost savings - all key parameters and factors for success in automotive and industrial systems. 200mm wafers enable a capacity increase, with almost twice the useful area for manufacturing integrated circuits compared to 150mm wafers, delivering 1.8 - 1.9 times as many working chips.
