Abstract
A semiconductor device includes: a trench; a first electrode is formed in the trench; a first impurity region, which has a first conductivity type and is formed to abut on the trench; a second impurity region, which has a second conductivity type and is formed to abut the trench; an insulating film, which is formed on the front surface of the semiconductor substrate; a conductive plug, which is formed to penetrate through the insulating film and is electrically connected to the first impurity region and the second impurity region; wherein the conductive plug includes: a silicon layer made of silicon other than a single crystal; a silicide crystallite contained in the silicon layer; and a blocking layer that is formed to cover sides of the silicon layer and is made of a material that is impervious to the silicide crystallites.
