Patent ID: 8314461

Claim:
A device comprising: a laterally diffused metal oxide semiconductor (LDMOS) transistor on a substrate, the LDMOS transistor including a first drain with a first drain-side n+ region, a first source with a first source-side n+ region and a first source-side p+ region, a first gate between the first drain and the first source, and a first lightly n-doped region in the first source that overlaps the first source-side n+ region and extends beneath the first gate but not the first drain; and an n-type complementary metal oxide semiconductor (CMOS) transistor on the substrate, the n-type CMOS transistor including a second drain having a second drain-side n+ region, a second source having a second source-side n+ region, a second gate between the second drain and the second source, and a second lightly n-doped region in the second drain that overlaps the second drain-side n+ region and extends beneath the second gate.
