摘要:
An SGT production method includes forming a pillar-shaped first-conductive-type semiconductor layer and forming a second-conductive-type semiconductor layer underneath the first-conductive-type semiconductor layer. A dummy gate dielectric film and a dummy gate electrode are formed around the first-conductive-type semiconductor layer and a first dielectric film is formed on an upper region of a sidewall of the first-conductive-type semiconductor layer in contact with a top of the gate electrode. A first dielectric film is formed on a sidewall of the gate electrode and a second-conductive-type semiconductor layer is formed in an upper portion of the first-conductive-type semiconductor layer. A second-conductive-type semiconductor layer is formed in an upper portion of the first-conductive-type semiconductor layer and a metal-semiconductor compound is formed on each of the second-conductive-type semiconductor layers. The dummy gate dielectric film and the dummy gate electrode are removed and a high-k gate dielectric film and a metal gate electrode are formed.
