Abstract
A channel region (9) between a source region (8) and a drain region (7) is overlaid with a silicon oxide film (2), polysilicon oxide film (3), silicon nitride film (4), silicon oxide film (5), and gate electrode (6). The polysilicon film and silicon nitride film constitute an interface state at the tunnel emission side closer to the oxide film (2). The interface state is made to serve mainly to hold charge for information storage to enable thinning of the silicon nitride film. Even an electron emission action such as erasure by tunneling from a nonvolatile storage device comprising a silicon nitride film to hold charge prevents the situation that unconsumable electrons from remaining in a gate insulation film. Erasure by hot hole injection is dispensed with.
