Abstract
A flash memory device including an isolation layer for defining active regions in a semiconductor substrate. The active region is a region in which flash memory cells are to be formed. The device also includes a gate stack is formed to come across the active region and the isolation layer, and a sidewall spacer is formed at sidewalls of the gate stack. The device further includes a common source line that electrically interconnects a plurality of sources of a plurality of the flash memory cells, and is formed in the isolation layer by removing an insulating material in the isolation layer and is formed in parallel to a word line formed over the gate stack. A silicide layer is formed in the common source line.
