Transistor structure having a conductive layer formed contiguous in a single deposition

Abstract

A semiconductor device is formed having a pedestal. The pedestal includes at least two dielectric layers. The pedestal has a sidewall and a major surface. A conductive layer is formed overlying the pedestal. A vertical portion of the conductive layer adjacent to the sidewall of the pedestal is a gate of the transistor. The portion of the conductive layer overlying the major surface can be used as interconnect. The gate and gate interconnect are contiguous and formed in a single process. A conductive shield layer may be integrated into the pedestal. The conductive shield layer functions as a faraday shield that reduces gate to drain capacitance of the device.
