    Why do we need a doped substrate?

    From my textbook, I know why we use the P well instead of using the p-doped substrate directly, but why do we need a doped substrate? I think this is a stupid question, and that's why I can't find out the ans from my testbook but considered that I am a new comer in semiconductor, please help me!
