Abstract:
1. A method for forming a storage device structure comprising: providing a substrate of a first conductivity type; forming overlying regions of sacrificial material; forming a first doped region of a second conductivity type opposite the first conductivity type and a second doped region of the second conductivity type within the substrate and on opposite sides of one of the regions of sacrificial material; forming a discrete charge storage layer overlying the substrate and between the regions of the sacrificial material; forming a first conductive control electrode and a second conductive control electrode overlying the substrate and on opposite sides of the one of the regions of sacrificial material, the first conductive control electrode and the second conductive control electrode each having a top surface and two sides; forming a first pair of select electrodes along the two sides of the first conductive control electrode and a second pair of select electrodes along the two sides of the second conductive control electrode; and forming a third doped region of the second conductivity type in the substrate between the first and second conductive control electrodes.
