ABSTRACT Power electronics devices are developed rapidly. There are some factors which influence the protective properties of the devices, including such as electrical characteristics of protection materials, the interface conditions of protective materials-pn junction, the surface effective charge density, the polarizable or unpolarizable properties of organic protective materials, etc.

电力半导体器件是近期发展起来的一类功率电子器件，其表面保护与其它电气元件不同，一方面要考虑器件表面绝缘保护材料的电性能和含杂等因素；另一方面，器件的表面钝化保护材料与器件接触后，器件的界面情况、材料与器件接触带电情况、以及材料所含官能团的极性等情况，也是影响器件性能的主要因素。
