    摘要: A method for manufacturing a MirrorBit® Flash memory includes providing a semiconductor substrate and successively depositing a first insulating layer, a charge-trapping layer, and a second insulating layer. First and second bitlines are implanted and wordlines are formed before completing the memory. Spacers are formed between the wordlines and an inter-layer dielectric layer is formed over the wordlines. One or more of the second insulating layer, wordlines, spacers, and inter-layer dielectric layers are deuterated, replacing hydrogen bonds with deuterium, thus improving data retention and substantially reducing charge loss.

    摘要: A method of fabricating a dual bit dielectric memory cell structure on a silicon substrate includes implanting buried bit lines within the substrate and fabricating a layered island on the surface of the substrate between the buried bit lines. The island has a perimeter defining a gate region, and comprises a tunnel dielectric layer on the surface of the silicon on insulator wafer, an isolation barrier dielectric layer on the surface of the tunnel dielectric layer, a top dielectric layer on the surface of the isolation barrier dielectric layer, and a polysilicon gate on the surface of the top dielectric layer. A portion of the isolation barrier dielectric layer is removed to form an undercut region within the gate region and a charge trapping material is deposited within the undercut region.
