| Zusammenfassung: | A semiconductor device includes a gate insulating film formed on the semiconductor substrate; a floating gate formed on the gate insulating film; a control gate formed on the floating gate and has a side coplanar with a side of the floating gate; a tunnel diffusion layer facing a portion of the floating gate; and a tunnel window formed in a portion of the gate insulating film between the floating gate and the tunnel diffusion layer, the tunnel window being formed to be thinner than a remaining peripheral portion of the gate insulating film. |
