Description

'The HomeCMOS project is dedicated to developing hobbyist-friendly processes for the microfabrication of CMOS and MEMS devices, providing documentation for these under the BSD open source licence. The project may be some way from being able to produce a usable IC, but the team has had success with a number of processes that make use of easily available materials, and have demonstrated etching a 600um long image into 200nm thick copper film."
