Abstract

A pair of source/drain regions are formed on a semiconductor substrate at a predetermined interval. A gate insulator film is formed on the semiconductor substrate between the source/drain regions of the pair. A gate electrode is formed on the gate insulator film. A film for covering the gate electrode and the source/drain regions has a low permeability against water and a hydroxide group, and has a thickness greater than 3 nm and less than 5 nm.
