Hi
I bet, we can cannibalise cheap laser-diodes from Blu-ray devices. I do not really like this DRM-stuff anyway :-)
Haha! Good stance! ;-)
BTW, Blu-ray devices use 405 nm laser-diodes [0] - which is *precisely* the H-line on ultraviolet photolithography [1]. The H-line is still visible for the human eye and known as "black light".
This is true
Are we crazy, thinking about a laser beamer, which is a turntable instead??? Doing Layouts not in a Cartesian but in a Polar coordinate system??? Even spin-coating seems to work.
To the first question: Yes :-)
- Minutes later -
Okay, I got lost on youtube watching a lot of DIY stuff with Blu-ray laser-diodes. Don't do this at home [2] :-o I guess a diode for Blu-ray players "ought to be enough for anybody"..
So, the reason why using a laser won't make you very happy, is the amount of time it takes to expose one single layout due to the scanning time. That's the reason why making masks with a laser scriber takes so long, and also the reason E-Beam takes a very long time, which also has to scan over the wafer.
