Patent ID: 7029975

Claim:
A method of forming a source line contact in a non-volatile memory comprising: masking a column in a matrix of memory cells, said column perpendicular to said source line and aligned with a plurality of source contact regions and said masking allowing for an implant of n-type dopants only in a region on a source side of said memory cells; forming a plurality of source implants in said regions on the source side of said memory cells, said memory cells arranged in a matrix of rows and columns, said matrix including at least one row of drain contacts for accessing drain regions in associated rows of memory cells in said matrix of memory cells; coupling said plurality of source implants to a plurality of source lines that are perpendicular to said column of source implants, for providing electrical coupling of said plurality of said source lines to said plurality of source implants; and further coupling a plurality of source contacts to said plurality of source implants, each of said plurality of source contacts located in-line with an associated row of drain contacts.
