摘要：
Low-stress silicon-rich SiNx deposited at or below 700 degrees C by either LPCVD or PECVD has been studied for potential use in the surface processing of a 45 GHz SiGe HBT IC-process. The films underwent a thermal anneal at 700 degrees C and in all cases a thin oxide buffer layer was necessary for achieving suitable film quality.
