Patent ID: 6906381

Claim:
A lateral semiconductor device comprising: a semiconductor region having a first surface and a first conductivity; first and second conductive regions extending into the semiconductor region from the first surface; a first additional region, having a second conductivity, between the first and second conductive regions, the first additional region extending into the semiconductor region from the first surface, wherein the first additional region forms a junction dividing an electric field between the first and second conductive regions when an electric path passes between the first and second conductive regions, the semiconductor region further comprising a first area having a first dopant concentration and a second area having a second dopant concentration, said second area extending from said first surface between said first conductive region and said first additional region, and said first additional region and said second conductive region, wherein the second area reduces series resistance between the first and second conductive regions when an electric path passes between the first and second conductive regions; and a plurality of additional regions, wherein each of the plurality of additional regions extends into the semiconductor region from the first surface and forms a junction dividing the electric field between the first and second conductive regions when an electric path passes between the first and second conductive regions.
