Abstract(in English) | We have fabricated a novel AlGaN/GaN HEMT with a multi-grooved and fin-shaped gate field-plate (G-FP), and studied its effect on the current collapse. Compared to the conventional gate FP device, the novel HEMT with a 3-dimensional FP (3DFP) structure exhibited a minimum increase in the dynamic on-resistance, demonstrating that an almost perfect collapse-free operation was achieved with a normalized dynamic on-resistance of less than 1.1. The results of groove depth dependence indicated that the current collapse in 3DFP HEMTs was most effectively suppressed when the groove depth was adjusted so that the bottom of the 3DFP electrode was aligned with the depth of 2-dimensional electron gas (2DEG) in a GaN channel. |
