I work at #Intel #Fab32 as a process engineer.
#AMA about semiconductor processing.
(I will not be answering questions about CPU design specifically, but about semiconductor processing in general)
@matt How can I make a nice lil Z80 type chip in my garage from household materials?
@Shufei This might be a useful resource to start you off in that direction:
Note that I cannot endorse this, as you'd be dealing with very dangerous processes and chemicals. Do not proceed unless you know what you are doing in a safe manner.
@matt Tank you! I would like it if we can make chips from safer things someday.
@Shufei Its very unlikely unless someone discovers a new process. You *need* very strong chemicals to break up oxide bonds; you literally cannot break up silicon oxides without a fluorine-based process (liquid HF or F+ ions in a plasma)
