Abstract:
A method of forming a pair of field effect transistors (FETs), said method comprising the steps of:a) forming a dielectric bridge between two gate conductors on a semiconductor layer, the two gate conductors being a pair of FET gates, including the steps of i) forming the pair of gates on a surface of the semiconductor layer, said gates being arranged such that a first portion is spaced closer together than a second portion, and ii) forming dielectric sidewall spacers along said gates, said sidewall spacers on one side of each of said pair of gates merging at said first portion; b) forming conduction regions in said semiconductor layer adjacent gate conductors, said bridge blocking formation of conduction regions between said two gate conductors immediately below said dielectric bridge; c) forming a passivating layer over said gate conductors and said dielectric bridge; and d) forming a body contact through said bridge to said semiconductor layer.
