  • Abstract
    In this work we present a thorough investigation of A1203 for use as an interpoly dielectric layer in flash memory devices. By exploring several optimization steps A1203 proves to be an excellent material for embedded flash applications. It is shown that a 17nm A1203 layer in combination with a high temperature post-deposition anneal and either a poly or (TiN) metal gate can provide excellent program/erase performance, data retention, program/erase cycling and data retention after cycling.
