摘要： Memory devices having an increased effective channel length and/or improved TPD characteristics, and methods of making the memory devices are provided. The memory devices contain two or more memory cells on a semiconductor substrate and bit line dielectrics between the memory cells. The bit line dielectrics can extend into the semiconductor. The memory cell contains a charge trapping dielectric stack, a poly gate, a pair of pocket implant regions, and a pair of bit lines. The bit line can be formed by an implant process at a higher energy level and/or a higher concentration of dopants without suffering device short channel roll off issues because spacers at bit line sidewalls constrain the implant in narrower implant regions.

摘要： Methods for fabricating dual bit flash memory devices are provided. Method steps include forming a charge trapping layer overlying a substrate and fabricating two insulating members overlying the charge trapping layer. A polycrystalline silicon layer is provided overlying the charge trapping layer and about sidewalls of the insulating members. Sidewall spacers are formed overlying the polycrystalline silicon layer and about the sidewalls of the insulating members. A portion of the first polycrystalline silicon layer and a first portion of the charge trapping layer are removed. A first insulating layer is conformally deposited overlying the insulating members and the substrate. A gate spacer is formed between the two insulating members and overlying the first insulating layer. The two insulating members are removed and the charge trapping layer is etched to form charge storage nodes. Impurity dopants are implanted into the substrate to form impurity-doped bitline regions within the substrate.

摘要： Methods of selectively forming metal silicides on a memory device are provided. The methods can include forming a mask layer over the memory device; forming a patterned resist over the mask layer; removing upper portions of the patterned resist; forming a patterned mask layer by removing portions of the mask layer that are not covered by the patterned resist; and forming metal silicides on the memory device by a chemical reaction of a metal layer formed on the memory device with portions of the memory device that are not covered by the patterned mask layer. By preventing silicidation of underlying silicon containing layers/components of the memory device that are covered by the patterned mask layer, the methods can selectively form the metal silicides on the desired portions of the memory device.
