    摘要: A method includes forming a blocking layer over a substrate, and etching the blocking layer to form a trench in the blocking layer. A dielectric layer is formed, wherein the dielectric layer comprises a first portion over the blocking layer, and a second portion in the trench. After the step of forming the dielectric layer, an implantation is performed to implant an impurity into the substrate to form a deep well region. After the implantation, the dielectric layer and the blocking layer are removed.

    摘要: A semiconductor device with multiple strap-contact configurations for a memory cell array. An array with memory cells interconnected with bit-lines, control-gate lines, erase gate lines, common-source lines, and word-lines is provided. In one aspect of an illustrative embodiment, a strap-contact corridor is spaced at n bit-line intervals (n>1) across the array. The strap-contact corridor comprises strap-contact cells, which provide electrical interconnection between control-gate lines, erase gate lines, common-source lines, and word-lines and their respective straps.

    摘要: A method for fabricating a gated semiconductor device, and the device resulting from performing the method. In a preferred embodiment, the method includes forming a hard mask for use in gate formation on one or more layers of alternately insulating and conducting material that have been formed on a substrate. The hard mask preferably includes three layers; a lower nitride layer, a middle oxide, and an upper nitride layer. In this embodiment, the middle oxide layer is formed with the rest of the hard mask, and then reduced in a lateral dimension, preferably using a DHF dip. A dielectric layer formed over the gate structure, including the hard mask, then etched back, self-aligns to be reduced-dimension oxide layer. In addition, where two conducting, that is gate layers are present, the lower layer is laterally reduced in dimension on at least one side to create an undercut.
