Abstract
A memory device, such as a flash EEPROM, employs a high energy implantation to form common source line, avoiding the necessity of self-aligned source etch processes. The use of the high energy implantation, and avoiding the etching process, provides for greater cell uniformity, and better V.sub.T distribution.
