    摘要: A manufacturing method for an integrated circuit memory includes providing a semiconductor substrate and depositing a charge-trapping dielectric layer. First and second bitlines are implanted and a wordline layer is deposited. A hard mask layer is deposited over the wordline layer. A photoresist is deposited over the wordline layer and used to form a hard mask. The photoresist is removed. The wordline layer is processed using the hard mask to form a wordline and the hard mask is removed. A reduced hydrogen, ultra-violet block data retention liner covers the wordline and the charge-trapping dielectric layer. The reduced hydrogen levels reduce the charge loss compared to prior art. The surface of the liner is processed to block UV light before completing the integrated circuit.

    摘要: A manufacturing method for a MirrorBit® Flash memory includes providing a semiconductor substrate and depositing a charge-trapping dielectric layer. First and second bitlines are implanted and a wordline layer is deposited. A hard mask layer is deposited over the wordline layer. The hard mask is of a material formulated for removal without damaging the charge-trapping dielectric layer. A photoresist is deposited over the wordline layer and used to form a hard mask. The photoresist is removed. The wordline layer is processed using the hard mask to form a wordline and the hard mask is removed. A salicide is grown without short-circuiting the first and second bitlines.

    摘要: A device and method for manufacturing thereof for 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: Methods and systems of fabricating a wordline protection structure are described. As described, the wordline protection structure includes a polysilicon structure formed adjacent to a memory core region. The polysilicon structure includes first doped region positioned on a core side of the polysilicon structure and a second doped region positioned on a spine side of the polysilicon structure. An un-doped region positioned between the first and second doped regions. A conductive layer is formed on top of the polysilicon structure and arranged so that it does not contact the un-doped region at either the transition between the first doped region and the un-doped region or the second doped region and un-doped region.
