On a GaN smart power IC platform, a robust GaN high electron mobility transistor (HEMT) with integrated gate protection is demonstrated by embedding a depletion-mode HEMT (D-HEMT) into the gate electrode of an enhancement-mode HEMT (E-HEMT). This protection scheme allows large input bias (e.g. 20 V) without gate-overdrive-induced reliability issues, and yields no penalties on the ON-state current and OFF-state ...

High performance InP-based InAlAs/InGaAs enhancement-mode HEMT's are demonstrated using two improved approaches to device structure design and fabrication, i.e., nonalloyed ohmic contacts and Pt-based buried-gate technologies, to reduce the source resistance (RS). With specially designed cap layer structures, nonalloyed ohmic contacts to the device channel were obtained providing contact resistance as low as 0.067 Ω*mm. Furthermore, in device fabrication, a ...

On a GaN smart power integrated circuit (IC) platform, a highly linear (i.e., proportional to absolute temperature) temperature sensor IC is demonstrated for building voltage references as well as temperature compensation functional blocks. The circuit is designed based on the temperature-dependent characteristics of GaN-based peripheral devices (e.g., heterojunction Schottky barrier diode, enhancement-/depletion-mode high electron mobility transistors, and lateral field-effect rectifiers) ...

We report a novel approach in fabricating high-performance enhancement mode (E-mode) AlGaN/GaN HEMTs. The fabrication technique is based on fluoride-based plasma treatment of the gate region in AlGaN/GaN HEMTs and post-gate rapid thermal annealing with an annealing temperature lower than 500/spl deg/C. Starting with a conventional depletion-mode HEMT sample, we found that fluoride-based plasma treatment can effectively shift the threshold ...

On a GaN smart power integrated-circuit platform, a monolithically integrated gate-protected high-voltage AlGaN/GaN enhancement-/depletion-mode high- electron mobility transistor (HEMT) has been proposed. It can sustain large input gate voltage swing (>; 20 V) with enhanced safety (no gate failure observed) and improved reliability (no observable shifting of the threshold voltage), and the breakdown voltage is not sacrificed. Such a protection ...
