On that note, you could technically just buy the chips and spend an inordinate amount of time and money building the PCB and firmware.
- webreac 5y agochips, pcb and mask (for the soldering pasta) are not so expensive. Soldering remains difficult and time consuming

Sure, if you want to make a 1 um process you can do that with a purchased wafer, some chemicals, and a spin plate. If you want to make a nm-scale process you'll need to have a serious budget.
