Popis: | A structure that exhibits superior data retention, compared to the conventional erasable programmable read-only memory (EPROM) cell, while still using phosphosilicate glass (PSG) passivation, is described. The nitrided self-aligned MOS (NIT-SAMOS) employs a thin layer of low-pressure chemical vapor deposition (LPCVD) nitride between the double-poly-gate structure and the poly-metal isolation dielectric, to reduce the possibility of contamination of the floating-gate area. Comparisons are made of EPROM data retention lifetimes, programmability, and UV erasability, and n- and p-channel device parameters. > |
