Abstract:
A method is provided for forming a split-gate memory cell having field enhancement regions in the substrate for improved cell performance. The method may include forming a pair of gate structures over a substrate, performing a source implant between the pair of gate structures to form a self-aligned source implant region in the substrate, performing a field enhancement implant process to form field enhancement implant regions, e.g., having an opposite dopant polarity as the source implant, at or adjacent lateral sides of the source implant region, and diffusing the source implant region and field enhancement implant regions to thereby define a source region with field enhanced regions at lateral edges of the source region. The field enhanced implant process may include at least one non-vertical angled implant.

Claim (Index 16):
The memory cell of  claim 12 , wherein the memory cell is a split-gate flash memory cell.
