<jesseg> Too bad the webpage is down
<jesseg> but, really homebrew semiconductor manufacturer? That's splendid!

<diginet> several people have been working on it
<jesseg> fascinating! so like silicon substrate, photo masking, etching, vapor plating, and electroplating? etc?
<diginet> yeah, I've been specifically working on formulating an "open source" photoresist which is water-developable
<diginet> (that can be exposed at freqs that are easy to acquire sources for)
<jesseg> wow cool
<jesseg> let me add this channel to my regular list so it joins when I start client :D
<jesseg> by freqs, you mean like uv?
<jesseg> rather than xrays?

<diginet> yes
<diginet> deep UV light sources are absurdly expensive
<jesseg> like deeper than from a mercury lamp?
<jesseg> a germicidal lamp
<jesseg> aka eprom eraser :P

<diginet> jesseg: yeah
<diginet> high enough freqs start getting absorbed by air so you then need a vacuum
<jesseg> fascinating
<jesseg> well why do they use such short wavelength?
<jesseg> I would have assumed it was so they could get finer details
<jesseg> due to the wavelength of light
<jesseg> diginet, I'd love to hear of your experiments and to learn what doesn't work about common photoresist that's sensitive to regular near-uv (like used on PCBs) and well just the whole enchilada!
