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.

    Can you reliably make a diode without creating an EPA superfund site?

    I've heard it said that the pump room in an IC fab is an especially nasty place.

    Superfund sites are polluted locations in the United States requiring a long-term response to clean up hazardous material contaminations. They were designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980.

    Attention, people, we're not discussing your retirement plans here.

    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.

    Just 3D print everything, bro.

    The difference is that you're making a small number of sorta working semiconductor devices, not good ones. You can bypass using most of the nasty stuff.
