WIRE TYPE SEMICONDUCTOR DEVICE, AND METHOD FOR FABRICATION THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a wire type semiconductor device capable of ensuring a restrained short channel effect and a high operation performance, and to provide an economical method for fabrication thereof. SOLUTION: A wire type semiconductor comprises a main unit, a semiconductor substrate equipped with a pair of support poles projected upward from the main unit and at least one fin projected upward from the main unit with its ends connected to the pair of support poles, at least one semiconductor wire formed separately on at least one fin with its ends connected to the pair of support poles, a common gate electrode formed enclosing the external surface of at least one semiconductor wire and a gate insulating film placed between at least one semiconductor wire and the common gate electrode.
