Abstract

This study examines the effect of gate recess depth on the electrical and RF performance of AlGaN/GaN high electron mobility transistors (HEMTs) before and after die-attach. Devices with greater recess depths exhibited more significant changes in transconductance, pinch-off voltage, and RF metrics, such as cut-off frequency (ft) and maximum frequency (fmax), compared to non-recessed devices. However, recessed devices also showed substantial increases in gate and drain leakage currents, indicating adverse effects of packaging-induced stresses.
