摘要
We have developed the deposition and studied the electrical characteristics, microstructure and thermal reliability of Ru-based contacts on n-type GaN as well as on AlGaN/GaN HEMT heterostructure. Ru, RuO2 and Ru-Si-O layers were deposited by reactive magnetron sputtering and annealed up to 900 degrees C. Amorphous, conducting RuSiO4 contacts with their extremely low reverse currents and thermal stability up to 900 degrees C, show great potential for use as Schottky contacts to n-type GaN and gate electrodes for AlGaN/GaN HEMT in high temperature, high power applications.
