Method for manufacturing electronic devices comprising non-volatile memory cells and lv transistors with salicided junctions

Abstract

A method for manufacturing electronic devices, such as memory cells and LV transistors, with salicided junctions, that includes: depositing an upper layer of polycrystalline silicon; defining the upper layer, obtaining floating gate regions on first areas, LV gate regions on second areas of a substrate, and undefined regions on the first and third areas of the substrate; forming first cell source regions laterally to the floating gate regions; forming LV source and drain regions laterally to the LV gate regions; forming a silicide layer on the LV source and drain regions, on the LV gate regions, and on the undefined portions; defining HV gate regions on the third areas, and selection gate regions on the first areas; forming source regions laterally to the selection gate regions, and source and drain regions laterally to the HV gate regions.
