Research Abstract |
Device fabrication procedure of diamond Schottky barrier diodes (SBD) for high voltage operation was investigated. By utilizing tungsten carbide as SBD metal, thermally stable device operation was obtained in the temperature range below 600K. Post annealing of SBD metals is found to be efficient for stabilizing the interface.For the purpose of improving SBD performance, growth condition that satisfies both higher crystalline quality and thicker diamond film growth was explored. Then suppression of substrate etching is crucial for diamond growth on highly boron doped substrate using higher microwave power density.
