Patent ID: 6870218

Claim:
A semiconductor device comprising: a semiconductor layer; a pair of spaced-apart field effect gate structures on a surface of the semiconductor layer, each gate structure including a first end portion facing the other gate structure and an upper surface; a layer of silicide formed over at least a portion of each upper surface of each gate structure; first and second spaced-apart source regions of a first conductivity type in a portion of the layer between the pair of gate structures, each source region self-aligned with respect to a corresponding one of the first end portions; first and second sidewall spacers each positioned over a different source region and against a different first end portion, said sidewall spacers being tapered from a relatively thick portion proximate the surface of the semiconductor layer to a relatively narrow portion proximate an upper surface of the gates; a lightly doped body region of a second conductivity type in the semiconductor layer and extending from below the source regions to below the gate structures; and a more heavily doped region of the second conductivity type extending into the portion of the surface between the first and second sidewall spacers; wherein said body region further includes an inflection in its depth in a portion thereof below the more heavily doped region of the second conductivity type.
