Patent abstract
A semiconductor device includes a semiconductor substrate, a gate insulating film, a gate electrode, a source/drain layer, and a germanide layer. The gate insulating film is formed on the semiconductor substrate. The gate electrode is formed on the gate insulating film. The source/drain layer is formed on both sides of the gate electrode, contains silicon germanium, and has a germanium layer in a surface layer portion. The germanide layer is formed on the germanium layer of the source/drain layer.
