| 摘要 |
A semiconductor device includes a semiconductor substrate containing silicon, a p-type semiconductor active region formed on the semiconductor substrate, a first gate insulating film containing at least one of Zr and Hf and formed on the p-type semiconductor active region, a first gate electrode formed on the first gate insulating film and formed of first silicide containing silicon and a first metal material and having a work function level lower than the central position of a band gap of the p-type semiconductor active region, and a first source region and first drain region configured by a second silicide containing silicon and the first metal material and formed to sandwich the p-type semiconductor active region.
