Google is offering to fab open-source chip designs for free.

They have to be on 130nm and quantities are limited to 100 ICs.

In a FOSSi (Free and Open Source Silicon) Dial-Up talk, Tim Ansell of Google announced SkyWater PDK, the first manufacturable, open source process design kit. 

The PDK allows you to produce an IC to be manufactured by the SkyWater foundry on the 130nm node.

The first wafer run will be in November and there will be more next year.

All open source chip designs qualify.
