Patent ID: 8890164

Claim:
A metal oxide semiconductor field effect transistor (MOSFET) for an integrated circuit, comprising: a substrate of a first conductivity type; a first well region of a second conductivity type located in the substrate; a second well region of the second conductivity type located within the substrate, wherein the second well region is functionally connected to the first well region and wherein the second well region has a surface area greater than a surface area of the first well region; a source of the first conductivity type located in the first well region; a drain of the first conductivity type located in the first well region; a substrate terminal of the second conductivity type located in the first well region; a gate oxide on a top surface of the first well region; and a gate electrode located on a top surface of the gate oxide wherein a junction area between the second well region and the substrate has a size sufficient to allow particles to flow from the second well region to the substrate at a rate that exceeds a combination of a rate of particle flow from the source to the first well region, a rate of particle flow from the drain to the first well region, and a rate of particle flow from the substrate terminal to the first well region.
