A project log for Semiconductors @ Home

Building all the tools neccesary to make chips at home.

Finally, all pieces are in place.

The gear has been built. The oven, the sputtering rig, the spin coater and the fume hood.

The chemicals have been bought.

All thar remains is to test, test, test...and then more testing. I would hope to have some kind of semiconductor device (a diode?) by september first, time will tell, some say.

For now, I would recommend to look at my twitter account where I post my findings and experiments in real time (using it as a kind of log/documenting process).

Points of update in Hackaday.io will be more or less the following:

1.- Succesful PMMA milling on a silicon substrate.

2.- Succesful SiO2 etching with HF 2%

3.- Succesful alignment of features for multiple masking process.

4.- First dopings.

5.- First DIODE.

6.- First aluminium sputtered connection for a diode.

7.- Realiability of repetition.

After that, FET tests will begin, wich are another can of worms.
