A method of manufacturing a semiconductor device having a p-type field effect transistor and an n-type field effect transistor includes the steps of: forming an interface insulating layer and a high-permittivity layer on a substrate in the stated order; forming a pattern of a sacrifice layer on the high-permittivity layer; forming a metal-containing film containing metal elements therein on the high-permittivity layer in a first region where the sacrifice layer is formed and a second region where no sacrifice layer is formed; introducing the metal elements into an interface between the interface insulating layer and the high-permittivity layer in the second region by conducting a heat treatment; and removing the sacrifice layer by wet etching, wherein in the removing step, the sacrifice layer is etched easily more than the high-permittivity layer. With this configuration, the semiconductor device excellent in reliability is obtained.

In a semiconductor device including at least one p-channel type MOS transistor, a silicon dioxide layer is formed on a silicon substrate, and a gate electrode is formed on the silicon dioxide layer. The gate electrode silicon has a three-layered structure including a silicon-seed layer formed on the silicon dioxide layer, a silicon/germanium layer formed on the silicon-seed layer, and a polycrystalline silicon layer on the silicon/germanium layer. An average grain size of polycrystalline silicon in the polycrystalline silicon layer is at most 100 nm, and p-type impurities are substantially uniformly distributed in the gate electrode along a height thereof, and the germanium atoms are diffused from the silicon/germanium layer into the silicon-seed layer at high density.
