    Semiconductors in general - started off as detectors for radar, (military money you see) you could even argue that they were an inevitable consequense. Oddly enough it was the Germans who started using them back in the 30's.

    It's also possible to make valves using modern chip building technology, so you don't even need the semiconductor effect to make a microprocessor, yes it would be less efficient but not by orders of magnitude. And at such small distances you don't need high voltages. Also valves are very tolerant of overheating and EMP.

    The Bipolar Transistor is the most important of the lot, no question that the explosion in electronics is directly related to it's invention more than any of the others.

    Anyway, CMOS logic isn't accurate, analogue all the way ;)
