Rohm has been running a GaN process at Hamamatsu for four years, initially with a 150V process and, since 2023, with a 650V process.
Rohm intends to have the TSMC process up and running in 2027.
In 2024 Rohm and TSMC agreed to collaborate on automotive GaN and this collaboration will end when Rohm has the automotive GaN process running in 2027.
However, the collaboration between Rohm and TSMC on power supply systems will continue.
