    摘要: A method of forming an MOS transistor by forming a poly gate over and insulated from a substrate, forming a layer of protective insulation material on the poly gate, and then performing a first implant of dopant material into portions of the substrate adjacent the poly gate, wherein the layer of protective insulation material and the poly gate block most or all of the first implant from reaching a portion of the substrate underneath the poly gate. One or more spacers are then formed adjacent the poly gate, followed by a second implant of dopant material into portions of the substrate adjacent to the one or more spacers.

    摘要: A method of forming a memory cell includes forming a conductive floating gate over the substrate, forming a conductive control gate over the floating gate, forming a conductive erase gate laterally to one side of the floating gate and forming a conductive select gate laterally to an opposite side of the one side of the floating gate. After the forming of the floating and select gates, the method includes implanting a dopant into a portion of a channel region underneath the select gate using an implant process that injects the dopant at an angle with respect to a surface of the substrate that is less than ninety degrees and greater than zero degrees.
