>>12576202Here's how you make a transistor on a silicon wafer at least, assuming you have already drawn up the circuit diagram of what it is you want to make, work out the rest for yourself from there
>Take pure(ish) silicon wafer>Apply photoresist>Etch out small patch>Dope the patch using ion implantation (shoot ions of dopant at it) or just regular old diffusion. >repeat application of photo-resist and doping to dope the wafer how you wish, congratulations you now how a transistor/diode or whatever it is you want.>Apply a small layer of conductive material on top (There a few ways to do this depending on specific conductor)>Etch out parts of the conductor however your circuit requiresYou have now obtained a very shit simple IC
