I just came along this: https://news.ycombinator.com/item?id=23524428
Wrap-up: Google and Skywater partner up to provide an open-source PDK
(incl. primitive library and models, mostly what we do) for an actually
existing technology node.
Compared to LS1U, MFS is 130nm, voltage range is 1,8V core + 3,3-5V IO, HV
MOS and SONOS is also available. What seem to be differentiating factors
- Only the PDK is open, the process steps not. Proprietary single-source
tech. with no geographical diversity
- Commercial mask-based volume-optimized foundry with the usual
pain-in-the-ass for MPW projects (expensive for the general public, takes
- Made-in-USA with DoD accreditation (can attract US govt customers, but
At the end, if we wish to underline the importance and necessity of our
work, we may need to put more emphasis on maskless lithography and a
business model geared towards unique, fast, cheap (i.e. comparable to a
catalog component) single-piece orders.
