Reduction in the short channel effect of a Flash EPROM cell is described. A method includes forming a gate structure on a substrate structure, and performing a nitrogen implant. Further included is performing device doping, wherein the nitrogen implant inhibits diffusion of dopant material into a channel of the cell. A Flash EPROM cell with reduced short channel effect includes a gate region, a drain region, and a source region, the source region and drain region defining a channel region therebetween beneath the gate region. The source region and drain region further have nitrogen implanted therein to reduce lateral diffusion of dopant material into the channel region.
