- amelius 5y agoInteresting. Curious what the yield is. And he doesn't need a cleanroom, or work with dangerous chemicals like HF?
- gear54rus 5y agoHe mentions HF around 4:05 but by that time I have long lost my understanding of whats going on so this may not be what you mean.
- inkeddeveloper 5y agoI feel this.
- berrynice 5y agoHe uses 1% HF, which is fairly managable.
- mmontagna9 5y agoI don't think you need a cleanroom if your feature sizes are huge.
- progre 5y agoMaking the masks in photoshop is a really neat trick. Reminds me of Bob Moore of Forth fame who said something like "once you have enough code to draw a square you are half way to a chip design package".

- andy_ppp 5y agoI loved this, it made me realise how close to negative development is to photolithography. When doing separate etching layers how are wafers lined up or is everything done in situ?
