Making the masks in photoshop is a really neat trick. Reminds me of Bob Moore of Forth fame who said something like &quot;once you have enough code to draw a square you are half way to a chip design package&quot;.

I loved this, it made me realise how close to negative development is to <i>photo</i>lithography. When doing separate etching layers how are wafers lined up or is everything done in situ?

Interesting. Curious what the yield is. And he doesn&#x27;t need a cleanroom, or work with dangerous chemicals like HF?
