I think a while ago I heard someone saying (or I read it, can't remember..) that the silicon for our semiconductor industry isn't just simple silicon. More, it is a special type of silicon but I cannot find appropriate information about that. I also can't get my head around of which type the silicon could or should be..
I'm aware of the different dopings which are required but I wouldn't see that as the silicon itself. Am I just wrong respectively do I fail to remember something correctly or is there something more about it, indeed?
