Abstract

An object is to provide a semiconductor device having high reliability and capable of high speed operation. The semiconductor device includes a silicon substrate, a silicon nitrided oxide film formed on the silicon substrate, and a gate electrode formed on the silicon nitrided oxide film. Nitrogen is distributed only in the vicinity of an interface between the silicon substrate and the silicon nitrided oxide film. In the vicinity of the interface, every nitrogen atom is bonded to two silicon atoms and one oxygen atom.
