Abstract
A semiconductor device including a silicon substrate, a gate insulator film formed on the silicon substrate and including silicon, deuterium, and at least one of oxygen and nitrogen, and a gate electrode formed on the gate insulator film wherein a deuterium concentration in a vicinity of an interface of the gate insulator film with the gate electrode is at least 1×107 cm−3, and a deuterium concentration in a vicinity of an interface of the gate insulator film with the silicon substrate is higher than the deuterium concentration in the vicinity of the interface of the gate insulation film with the gate electrode.
