  • Method of manufacturing a DMOS
    Patent number: 4849367
    Abstract: A method of manufacturing a DMOS is disclosed. On a polysilicon gate layer, a multiple dielectric mask including studs (71) defines a window (70) for body implantation (80) into a substrate. Unmasked regions of polysilicon and substrate are oxidized to form oxide regions (84,85,88). Subsequent to the removal of the protective studs and a portion of the oxide, remaining oxide regions (90,91,92) act as a mask for source implantation (99,100).
