    "Photolithography" is actually "writing on stone with light". But I've never fabbed a chip with my own hands, so I'll shut up.

    *Hackaday* Please add or pin a link to this guy's YT channel. I just heard him reference it at 3/4 of the way through (~27:00), then looked in the description and comments but didn't see anything. BTW this guy deserves the Hack-a-Decadal award. With a major honorary mention to Jeri Ellsworth and Ben Krasnow. This is the most inspiring and insightful story I've seen since taking up hobby electronics in '14. This is freaking amazing. Kudos to everyone that enabled and supported this guy's ambitious curiosity. ...and suddenly my DIY photoresist troubles with PCB's seem so much less significant... lol..thanks for the reality check ;) -Jake

    I remember when ion-implantation was a strictly experimental process, used only in university-level material science research labs. I'm old enough to have had a grad student TA show off his experimental piece. What would be really cool would be this guy developing the setup and skills to build digital-analog hybrid chips, which are a lost art to the commercial fabs.

    @@wormwoodbecomedelphinus4131 Not really, that's why we switched to things like LCD panels. NTSC is an analog standard, and so are PAL, SECAM and VGA. HDMI, DVI, and DisplayPort are digital ones. The digital ones mostly give a more reliable picture quality without needing as many adjustments. (NTSC also was pretty bad at color, which was tacked on after the standard was in use for more than a decade, and had to be done in a way that an NTSC compliant set without color capability wouldn't notice the color information. This meant it never worked all that well and needed a lot of adjustments.)

    @@evensgrey PAL was made a decade after NTSC specifically to address NTSC's problems. You could think of it as NTSC: Second Edition. It has NTSC's advantage of being backwards-compatible with black-and-white sets while fixing the main bugs, even while using the same core concept (QAM for the colour). SECAM also took a whack at solving the problem, but instead of trying to refine NTSC's approach, its designers decided to throw it out and try something else (FM for the colour). SECAM doesn't get luma/chroma interference, while PAL and NTSC do. On the other hand, you can directly mix the composite signal for PAL and NTSC and get similar results to working in RGB, but you can't for SECAM.

    @@dmacpher I apologize for not being clear. I didn't mean to imply he doesn't use it. I mean how he uses it. That is a pretty powerful machine capable of techniques he will probably never need or use. My point was never to insult him - the guy is obviously intelligent and very dedicated. And, in fact, did build a fab. My point was, that is not a "garage lab" in the typical sense of the word. If there is a $million+ in equipment in that lab I would not be surprised. He's better equipped than some of the smaller research colleges I have seen. So, Hackaday saying it is a "small budget" in a "home workshop" is a bit misleading. I hope that is clearer.

    You can easily decap ICs by simply burning it in a candle flame! Blow torch works, too. Epoxy flash point is around 170-200°C, a lot lower than the melting temp of the layers on the chip. Mind you the fume is very toxic, so better do it outside. Then break the burned packaging easily, carefully take the chip out and clean (brush) it with IPA, thinner, etc.

    If you are enthusiastic, patient, persistent, and resourceful, it is inevitable that you will find the equipment that you always wanted. He mentioned all the low cost methods used to make these chips (Hacking a DLP project with custom optics, The low cost microgram scale, using off-the-shelf chemical solutions, etc) and how he just basically went dumpster diving and waited to acquire higher end equipment. Apparently he doesn't live too far from Princeton, so sounds like there are quite a bit of opportunities to get equipment for free and super-cheap.

    Like he says, it is possible to "accumulate" this stuff over time, if you're careful. My old university was terrible (well, great, from my point of view!) at throwing stuff out - years ago, I managed to scrounge/salvage/beg enough stuff for a diffusion-pumped vacuum system that could coat mirrors, and a few years later I got hold of a turbopump, and parts from an insanely heavy electron-beam welder.
