Abstract
An improved slot etch technique based on an Si planar doped layer has been applied to gate recessing in the fabrication of AlGaAs/InGaAs/GaAs pseudomorphic high electron mobility transistors (HEMTs). The devices exhibited comparable gm with much better breakdown and leakage behaviour than conventional pseudomorphic HEMT devices
