Patent ID: 7550348

Claim:
A method for forming a storage device structure comprising providing a semiconductor substrate; forming a first plurality of spaced apart doped regions in the semiconductor substrate; forming a plurality of spaced apart storage regions over the first plurality of spaced apart doped regions; forming a plurality of spaced apart first electrodes over the plurality of spaced apart storage regions; forming first sidewall spacers on sidewalls of the plurality of spaced apart first electrodes, wherein the first sidewall spacers comprise one of a group consisting of a material that can be doped to become conductive and a first conductive material; implanting dopants using the first sidewall spacers as a mask to form a second plurality of spaced apart doped regions in the semiconductor substrate; forming a second conductive material over the second plurality of spaced apart doped regions; and forming contacts that electrically connect the second conductive material and the second plurality of spaced apart doped regions.
