Hackaday reports a
crowdfunded effort to make custom silicon of an open source SoC design, MRISC-V:

If you want to get your hands on one of these open microcontrollers, the Crowd Supply campaign is actually fairly reasonable, considering this is custom silicon. $49 USD gets you a first-run mRISC-V in a QFN-32 package. $99 gets you the mRISC-V dev board with an SD card slot, USB, regulators, and of course the micro itself.

The 2x2mm chip will be made in a 130nm process and aims to be the equivalent of commercial microcontrollers implemented with an ARM M0 core.
Quote:
The OnChip Open-V microcontroller is a completely free (as in freedom) and open source 32-bit microcontroller based on the RISC-V architecture. ... This isn’t just a one-time thing - we’re planning on keeping the Open-V in production for as long as there is demand. Our initial manufacturing run will produce approximately 70,000 chips.
There's an interesting tabulation on the
crowdfunding site comparing various microcontrollers.
(we've mentioned RISC-V
before - in that case, the lowRISC linux-capable implementation.)
