Patent ID: 7579247

Claim:
A method of forming a re-programmable non-volatile memory, comprising: forming a layer of charge trapping dielectric over an area of a semiconductor substrate surface, thereafter forming a plurality of first strips of conductive material on the charge trapping dielectric layer that are spaced from each other in a first direction across the area and have lengths extending in a second direction across the area, the first and second directions being orthogonal with each other, thereafter forming a layer of conductive material over the first conductive material strips with a layer of dielectric therebetween and over the spaces between the first strips, thereafter separating the layer of conductive material into a plurality of second strips that have lengths extending in the first direction and which are spaced apart in the second direction, thereafter removing portions of the first strips of conductive material in spaces between the second strips in the second direction, and whereby portions of the first strips of conductive material remaining under the second strips overlay portions of the layer of charge trapping dielectric carried by the substrate to form charge storage elements.
