Abstract

A method of fabricating an ETOX flash memory. A low-resistance source line is formed on the substrate to string each source region in one source array by self-aligned process to substitute conventional buried source line. And at the same time, landing pads are formed on the each drain region by a self-aligned process to reduce the fabrication difficulty of the contact plug.
