When making chips using lithographic techniques, How are the transistors and capacitors and other components "printed" onto the board?
When we print one we use things like UV or E-beam to print out the shape we want (using some kind of mask), but after we're left with the desired shape, how are the transistors, capacitors, resistors (and so on) placed? Are they there all along somehow?
I bet this question has a simple answer but I must be mis-interpreting some concept which doesn't let me understand.
