Title
Enhancement-Mode Algan/Gan Hemts With Low On-Resistance And Low Knee-Voltage
Abstract
Based on fluoride-based plasma treatment of the gate region in AlGaN/GaN HEMTs and post-gate rapid thermal annealing (RTA), enhancement mode (E-mode) AlGaN/GaN HEMTs with low oh-resistance and low knee-voltage were fabricated. The fabricated E-mode AlGaN/GaN HEMT with 1 mu m-long gate exhibits a threshold voltage of 0.9 V, a knee-voltage of 2.2 V, a maximum drain current density of 3 10 mA/mm, a peak gm of 148 mS/mm, a current gain cutoff frequency fT of 10.1 GHz and a maximum oscillation frequency f(max) of 34.3 GHz. In addition, the fluoride-based plasma treatment was also found to be effective in lowering the gate leakage current, in both forward and reverse bias. Two orders of magnitude reducation in gate leakage current was observed in the. fabricated E-mode HEMTs compared to the conventional D-mode HEMTs without fluoride-based plasma treatment.
