    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 dual bit flash memory includes providing a semiconductor substrate and depositing a charge-trapping dielectric layer with the depositing performed without using ammonia at an ultra-slow deposition rate. 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, high-density data retention liner to reduce charge loss, covers the wordline and the charge-trapping dielectric layer. An interlayer dielectric layer is deposited over the data retention liner.

    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 manufacturing for a MirrorBit® Flash memory includes depositing a charge-trapping material over a semiconductor substrate and implanting first and second bitlines in the semiconductor substrate. A wordline material is deposited over the charge-trapping dielectric material and a hard mask material deposited thereon. An anti-reflective coating (ARC) material is deposited on the hard mask material and a photoresist material is deposited on the ARC followed by processing the photoresist material and the ARC material to form a photomask of a patterned photoresist and a patterned ARC. The hard mask material is processed using the photomask to form a hard mask. The patterned photoresist is removed and then the patterned ARC without damaging the hard mask or the wordline material. The wordline material is processed using the hard mask to form a wordline and the hard mask is removed without damaging the wordline or the charge-trapping material.
