摘要：
In devices such as recess gate MESFETs and in SITs, the Schottky gate is formed on a plasma etched surface. The quality of this interface is crucial to the performance of these devices. This study considers sacrificial oxidation as a post-etch, pre-metallization treatment for SiC Schottky diodes. Current-voltage and X-ray Photoelectron Spectroscopy measurements are used to determine the effect of two different sacrificial oxidation methods on plasma etched and unetched n-type 4H-SiC.
