Patent ID: 7202538

Claim:
A MOSFET transistor structure formed in a substrate of semiconductor material having a first conductivity type; the MOSFET transistor structure consisting of: a single rectangular active region formed in the substrate, the single rectangular active region having a substantially rectangular perimeter; perimeter isolation dielectric material formed in the substrate along the entire substantially rectangular perimeter of the single active region to define a continuous substantially rectangular interface between the isolation dielectric material and the single rectangular active region; a single, contiguous source region and a single, contiguous drain region formed in the single rectangular active region to define a substrate channel region therebetween, both the single source region and the single drain region having a second conductivity type that is opposite the first conductivity type and also being spaced-apart to define a substantially rectangular substrate channel region therebetween, the substrate channel region having the first conductivity type; and a conductive gate electrode that consists of a first portion that extends over the substantially rectangular substrate channel region and a second portion that extends continuously over the entire substantially rectangular interface between the isolation dielectric material and the single rectangular active region, the conductive gate electrode being separated from the substantially rectangular substrate channel region by intervening gate dielectric material, the conductive gate electrode having one opening formed therethrough over the source region and a second opening formed therethrough over the drain region.
