Google has announced a partnership with SkyWater Technology, a semiconductor engineering and manufacturing foundry based in Bloomington, Minnesota. Through the open source design kit, developers with limited funds can create chip products through the 130nm process, and it was announced earlier that this service will provide 90nm process technology for free.
The 90nm process technology is provided for free this time. It can still be used through the SKY90-FD open source design kit cooperating with Google and SkyWater Technology and can be operated through a web server environment that conforms to the Apache 2.0 specification.
The 90nm process technology provided this time 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.
Like the previously provided 130nm process, although the current process technology has dropped to smaller specifications, the process technology provided by itself can still be used for most IoT devices and passive component designs. By providing different process technologies, Google is expected to drive the development of more diverse open-source chip designs.
