how did you make the transistors? made your own vacuum chambers?

i had to make logic gates and so on, but i wouldnt say i really learnt it, even if back in highschool i learned all the different things a 555 timer can do

We had a photolithography lab when I was at school. It's not that complicated to make a few npn transistors. The difficult part is doing it well.
