Hi everyone this is Matt H I am a college student studying Microelectronic Engineering (making computer chips). I wanted to apply what I learned and came up with the idea to make my own cleanroom to test experiments. This instructable covers how to build a cleanroom/cleanbox and preform photolithography, oxide growth, and etching at home. These steps are integral processes to how modern computer chips are made. Due to a limited budget instead of making a whole room into a cleanroom I had the idea of making a glovebox like design with modifications. Also due to limited budget the results are a whole lot larger then modern techniques and I followed a similar approach as did the early pioneers of transistors. This is to be assembled in a spare room or garage where it is dark. Building this should only be attempted if you have knowledge of semiconductor manufacturing and know the proper safety precautions.

If you are only making a few diodes, it will probably be fine as long as you wear gloves and don't drink the etching fluid.
