    摘要: A nonvolatile memory cell array having common drain lines and method of operating the same are disclosed. A positive voltage is applied to a gate of a selected cell and gates of memory cells that share a word line with the selected cell. A first voltage is applied to a drain of the selected cell and drains of the memory cells that share at least a drain line with the selected cell. A second voltage is applied to a source of the selected cell and sources of memory cells that share a bit line with the selected cell, the second voltage being less than the first voltage, such that electrons are injected into the charge storage region of the selected cell to program. A third voltage, which is higher than the second voltage, is applied to bit lines that are not connected to the selected cell.

    摘要: A method of forming an SOI semiconductor substrate and the SOI semiconductor substrate formed thereby, is provided. The method includes forming sequentially buried oxide, diffusion barrier and SOI layers on a semiconductor substrate. The diffusion barrier layer is formed by an insulating layer having a lower impurity diffusion coefficient as compared with the buried oxide layer. The diffusion barrier layer serves to prevent impurities implanted into the SOI layer from being diffused into the buried oxide layer or the semiconductor substrate.

    摘要: A method of manufacturing a non-volatile semiconductor memory device begins by forming a dielectric layer pattern having an ONO composition on a substrate. A polysilicon layer is formed on the substrate including over the dielectric layer pattern. The polysilicon layer is patterned to form a split polysilicon layer pattern that exposes part of the dielectric layer pattern. The exposed dielectric layer is etched, and then impurities are implanted into portions of the substrate using the split polysilicon layer pattern as a mask to thereby form a source region having a vertical profile in the substrate.
