Patent ID: 7375398

Claim:
A FET comprising: a substrate that includes implants of a first type; a first well in the substrate that includes doped implants of the first type; a second well in the substrate that includes doped implants of a second type, the second well adjacent to the first well and defining a natural p-n junction with the first well; a field oxide layer within the second well that defines a first surface region and a second surface region of the second well, wherein the second surface region of the second well is adapted to receive a drain contact, and wherein the field oxide layer is outside the first well; a third well located at least partially in the first well, the third well including doped implants of the second type and adapted to receive a source contact, the third well thereby defining a channel between it and the second well within the first well; and a gate disposed over the channel, wherein at least a first portion of the gate is doped with implants of one of the first type and the second type the first portion being disposed substantially over the first well, wherein a second portion of the gate adjacent to the first portion is disposed substantially over the natural p-n junction the second portion including doped implants of the first type, and wherein a third portion of the gate adjacent to the second portion but not the first portion is disposed over the field oxide layer within the second well.
