Abstract

A MIS transistor comprises a semiconductor substrate having a first conductivity type, a source region and a drain region disposed in the semiconductor substrate in spaced-apart relation from one another and having a second conductivity type, and an insulating film disposed on the surface of the semiconductor substrate. A gate electrode is disposed on the insulating film between the source region and the drain region. A diffused region having the first conductivity type is disposed in the semiconductor substrate and in contact with the source region. An oxide film is disposed on the diffused region.
