摘要

The control of chemical composition and bonding features at a SiO2/GaN interface is a key to realizing high-performance GaN power devices. In this study, an similar to 5.2-nm-thick SiO2 film has been deposited on an epitaxial GaN(0001) surface by remote O-2-plasma-enhanced chemical vapor deposition (O-2-RPCVD) using SiH4 and Ar/O-2 mixture gases at a substrate temperature of 500 degrees C. The depth profile of chemical structures and electronic defects of the O-2-RPCVD SiO2/GaN structures has been evaluated from a combination of SiO2 thinning examined by X-ray photoelectron spectroscopy (XPS) and the total photoelectron yield spectroscopy (PYS) measurements. As a highlight, we found that O-2-RPCVD is effective for fabricating an abrupt SiO2/GaN interface. (C) 2018 The Japan Society of Applied Physics
