Abstract
According to an aspect of the invention, a semiconductor device comprises: a N-channel MIS transistor comprising; a p-type semiconductor layer; a first gate insulation layer formed on the p-type semiconductor layer; a first gate electrode formed on the first gate insulation layer; and a first source-drain region formed in the p-type semiconductor layer where the first gate electrode is sandwiched along a direction of gate length. The first gate electrode comprises a crystal phase including a cubic crystal of NiSiwhich has a lattice constant of 5.39 angstroms to 5.40 angstroms.
