First Claim
Patent Images
1. A semiconductor device comprising:
- a semiconductor die having a first major surface;
a first electrode schottky coupled to a portion of said first major surface;
a second electrode electrically connected to said first major surface of said semiconductor die, but spaced from said first electrode; and
a guard diffusion formed in said semiconductor die in a region at least partly between said first electrode and said second electrode, wherein said semiconductor die includes a first lightly doped portion and a second highly doped portion, said first lightly doped portion being disposed over said second highly doped portion, and further comprising a sinker extending from a major surface of said first portion to said second portion, and wherein said second electrode is electrically connected to said sinker.
