    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 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 technique for forming at least part of an array of a dual bit memory core is disclosed. A Safier material is utilized in the formation process to reduce the size of buried bitlines in the memory, which is suitable for use in storing data for computers and the like. The smaller (e.g., narrower) bitlines facilitate increased packing densities while maintaining an effective channel length between the bitlines. The separation between the bitlines allows dual bits that are stored above the channel within a charge trapping layer to remain sufficiently separated so as to not interfere with one another. In this manner, one bit can be operated on (e.g., for read, write or erase operations) without substantially or adversely affecting the other bit. Additionally, bit separation is preserved and leakage currents, cross talk, as well as other adverse effects that can result from narrow channels are mitigated, and the memory device is allowed to operate as desired.
