This work reports the development and fabrication of large area AlGaN/GaN-on-Si HFETs for the use in highly-efficient fast-switching power converters. High performance is demonstrated by full characterization of static- and dynamic-parameters and a direct comparison to two commercial state-of-the-art silicon power devices. Compared to their silicon(More)
AlGaN/GaN-on-Si Heterostructure Field-Effect Transistors (HFETs) for power switching are investigated in this paper. A design study for a fast switching environment for power devices is provided including an analysis of the technology, the fabrication, and the performances of large-area AlGaN/GaN-on-Si HFETs. Different power packages and high-current(More)
The degradation of packaged GaN HEMTs for high power applications has been studied under long term reverse bias step stress tests. Increases of leakage current and dynamic R<sub>on</sub> resistance have been found. This degradation is possibly caused by the formation of localized defects which have been observed by backside electroluminescence imaging. In(More)
AlGaN/GaN HFETs yield excellent properties for highly-efficient power-switching devices. A key parameter of highly-efficient switches is the static on-state resistance of the transistor. This paper discusses the main parameters affecting the on-state resistance and in particular the influence of resistive metallization in lateral finger structures and(More)
