Okay, I studied ASIC design in college. It was actually my specialization, though I'll admit I was never able to land a job in ASIC design. But still, I took those classes through the 500 level, most of the way to a masters and created functioning silicon. I know every word mentioned in there. I'm familiar with every concept mentioned. And yet, it all sounds like gibberish. n-type and p-type are determined by their substrate. n-type, negative charge. p-type, positive charge. The difference between n-type and p-type is if you apply a positive charge to the gate to turn it on, or apply a negative charge to the gate to turn it on. But historically, p-types are extremely large on silicon, and as such, takes up a lot of real estate, so because of that though CMOS is ideal for leakage speed, nobody uses them, because they're too expensive to produce. Everybody strictly uses n-type transistors. How are you changing the transistor type without fundamentally changing the charge of the substrate. I mean, hell, it'd be a big enough of an advancement just to make a p-type that's the same size as an n-type, and to hell with them switching.
