Abstract

Metal Semiconductor Field Effect Transistors fabricated using compound semiconductor materials have important applications in high-speed/low-noise communication systems. However, their integration densities are low compared to silicon technologies, and it is difficult to combine them with conventional CMOS for single-chip, mixed-signal circuit applications. In this paper we describe how silicon-on-insulator MESFETs can be fabricated alongside conventional MOSFETs using a commercially available silicon-on-insulator foundry. The process flow for the integrated MOSFETS and MESFETs is presented. Measurements from MESFETs fabricated using a commercial foundry demonstrate good depletion-mode device operation. The measured data confirms a square-law behavior for the saturated drain current, which can be reproduced using readily available MESFET models for Spice circuit simulation. The Spice model is applied to a simple differential-pair amplifier and the modeled results compared to measured data.
