Skywater

It’s great to learn that Google announced the expansion of its partnership with SkyWater Technology. They are working together to release an open source process design kit (PDK) for SKY90-FD, SkyWater’s commercial 90nm fully depleted silicon on insulator (FDSOI) CMOS process technology. SKY90-FD is based on MIT Lincoln Laboratory’s 90 nm commercial FDSOI technology, and enables designers to create complex integrated circuits for a diverse range of applications.
