Are you referring to Jeri Ellsworth? As far as I know
she only fabricated
an IC with simple logic gates on them, but it's possible she may have gone
on to do more complex stuff, like a CPU.
I think the reference was to Sam Zeloof:

I don't think he's done a CPU but he was up to ~100 transistors on a
chip when last I looked.
Maybe one day he'll be able to fabricate working Qbus transceiver chips ...
