Abstract
A semiconductor device whose working life can be improved is obtained. This semiconductor device comprises a first conductive layer, a second conductive layer and a silicon oxide film, formed between the first and second conductive layers, containing chlorine introduced therein. Thus, the silicon oxide film is inhibited from formation of electron traps while a large number of holes are formed in an initial stage of electron injection into the silicon oxide film.
