Method for forming flash memory cell

摘要

A method for forming a flash memory cell forms an insulating layer on a provided substrate and a number of openings are formed within the insulating layer to expose the substrate. A patterned conductive layer having a dopant is formed and fills the openings on the substrate. By driving the dopant into the substrate, source/drain regions are formed. A gate structure is formed on a channel region between the source/drain regions to accomplish the flash memory cell.
