  • > Gotham Silicon: 1μ CMOS process that will ship custom chips for –$100 in <24hrs

    > custom chips for –$100

    ...are they going to make it up in volume?

  • Too few details to be believably true. Too few details to be a good joke. I don't get it.

  • Yeah like others it's the 24h that's least believable here. There have been MPC/MPW (multi project chip/multi project wafer) services that could deliver 0.35um parts at comparable cost, but with several month turnaround. cmp.imag.fr was one but it's domain squatted now.

  • https://wp.josh.com/2025/10/30/a-billion-digits-of-pi-experi... has some details. Seems plausible?

  • Sounds great as a slogan, but there are no details. For comparison, Intel's 1 um process (Fab 3, 80386-era) required about 4 weeks of processing time, and if pushed, the samples could be processed in as little as two weeks. For a long time they were getting about one working die per 4" wafer.

  • Hey everyone my name is Miles this is my project. I am serious about 24hrs and know it's possible (at least for NMOS) because my record is 8 hrs from virgin wafer to cascadable NMOS devices (not even that heavily speed optimized). These NMOS devices had very poor characteristics, were very fragile, and the process was not repeatable. I am currently solving these problems (all of which have tractable and commercially demonstrated solutions) and intend to sell NMOS in the coming months. I have designs for the 24hr CMOS version and have strong conviction it will work. I am putting together a new page on gothamsilicon.com so people can have much greater insight into what I'm working on/how (expect this by EOD today). It will include information about my technical approach, process run sheets I have ran/intend to test, code and documentation for tools I have made/use, experimental data, and most excitingly POV footage of entire lab sessions. I am trying to figure out ways to livestream lab sessions. For a sample of this POV footage and to get notified when I start uploading the long sessions check out my youtube https://www.youtube.com/@nfjesifb/streams . Anyway please AMA.

    P.S. if you or anyone you know is good at MOS device fab and/or has extensive experience at the Berkeley Nano Lab I want to talk to you. Also if you want to make stuff with this kind of process let's talk.
