Abstract:
1. A wire-type semiconductor device comprising: at least one pair of support pillars protruding above a semiconductor substrate; at least one fin protruding above the semiconductor substrate and having ends connected to the at least one pair of support pillars; at least one semiconductor wire having ends connected to the at least one pair of support pillars and being separated from the at least one fin; a common gate electrode surrounding the surface of the at least one semiconductor wire and covering an upper portion of the fin on the semiconductor substrate; a first gate insulating layer between the at least one semiconductor wire and the common gate electrode; and a second gate insulating layer between the at least one fin and the common gate electrode, wherein the at least one semiconductor wire is formed above the at least one fin, and end portions of the at least one semiconductor wire are exposed by the common gate electrode and are doped with first conductive type impurities.
