November 7, 2023 — ROHM Semiconductor recently announced that it will produce 8-inch (200mm) silicon carbide wafers at its second fab in Miyazaki Prefecture, Japan, and is expected to start operations in 2024.
After acquiring German silicon carbide wafer manufacturer SiCrystal in 2009, Rohm produces silicon carbide wafers at its factory in Nuremberg, Germany. For business continuity planning, ensuring a stable and secure supply chain, and expanding production capacity, Rohm decided to establish a silicon carbide wafer production line in Miyazaki Prefecture, Japan, making it the second production base of Rohm’s silicon carbide wafers.
The Miyazaki second fab was originally the factory of Solar Frontier, a subsidiary of Idemitsu Kosan. Rohm is about to acquire the fab in a deal. Once converted into ROHM’s second fab in Miyazaki, it will become ROHM’s largest silicon carbide power semiconductor fab.
According to Rohm Semiconductor, its goal is to achieve silicon carbide power semiconductor revenue of 100 billion yen in fiscal 2025, while increasing production capacity to six times that of fiscal 2021.
