摘要
In this paper, we describe the experimental methods and the results on the evaluation of the Schottky barrier which is formed by vacuum-evaporation aluminum on chemically etched n-type 6H-SiC. And we report the effects of edge termination of amorphous SiC using Reactive Ion Etching (RIE) and sputtering method. Edge termination was done by amorphous SiC in the trench etched by RIE using CF4 and O-2. Amorphous SiC was formed by sputtering poly-SiC. Schottky barrier diodes have higher breakdown voltage at 300 V and lower leakage current than those without the edge termination.
