发明名称 SELF-ALIGNED STRUCTURE FOR BULK FinFET
摘要 A FinFET structure which includes a bulk semiconductor substrate; semiconductor fins extending from the bulk semiconductor substrate, each of the semiconductor fins having a top portion and a bottom portion such that the bottom portion of the semiconductor fins is doped and the top portion of the semiconductor fins is undoped; a portion of the bulk semiconductor substrate directly underneath the plurality of semiconductor fins being doped to form an n+ or p+ well; and an oxide formed between the bottom portions of the fins.
