Abstract:
A non-volatile memory device used for non-overlapping implant, said device comprising:a substrate; a plurality of parallel bit lines located in said substrate and arranged in a first direction; a gate oxide layer located over said a plurality of bit lines to cover said substrate and said a plurality of bit lines; a plurality of parallel word lines with spacers located over said gate oxide layer and arranged in a direction perpendicular to said first direction; and a plurality of parallel dielectric layers arranged in a first direction and located over said gate oxide layer and said plurality of parallel word lines, wherein each location of said plurality of dielectric layers over said gate oxide layer and said word lines exactly aligns to each corresponding location of said plurality of bit lines in said substrate, and a plurality of openings are located at intersections between said plurality of parallel word lines and said parallel dielectric layers to expose the surface of said gate oxide layer.
