As a protective film , the passivation technique which consists of ( nh4 ) 2sx solution as pretreatment , and then low - temperature ( 80 ) sinx film , finally high - temperature sinx film should be adopted 在此基础上提出了较佳的钝化条件：先以湿法硫钝化作为gaas器件表面钝化，再用低温( 80 ~ ) sin _ x膜保护硫钝化表面，最外层淀积高温( 230 ) sin _ x膜。
About the critical force on the scratch tests , it was 45un . the p - sion films had a refractive index about 1 . 65 . from the study , it is apparent that teos - sio2 and teos - sion films possess high quality compared with sih - film as dielectric film and passivation film 通过实验研究可以看出，与传统的sih _ 4系sio _ 2介质膜和sion钝化膜相比， teos系薄膜作为介质膜和表面钝化膜具有膜质优良、可控性好的特点。

Firstly , the basic principle of solar cell is summarized ; secondly , the study on selective diffusion for crystalline silicon solar cell is introduced , including the explain away structure of selective emitter solar cell and the technological design of selective diffusion ; at last , the research of surface passivation in theory is expounded 首先，简要阐述了太阳电池的基本原理；其次，阐述了晶体硅太阳电池选择性扩散的研究(其中包括选择性发射极太阳电池的结构说明和选择性扩散的工艺设计) ；最后，阐述了表面钝化的理论研究。
However , the refractive index will increase with the increase of the flow ratio of sifu / nhs , slightly increase with the increase of substrate temperate , and decrease with the increase of rf power . by measuring the passivation results of hydrogen plasma and sinx thin film , we found an evident improvement of minor carrier lifetime in polycrystalline silicon after hydrogen plasma treatment , although it has little to do with the annealing temperature and time . the hydrogen contained in sinx thin film can enhance the carrier mobility of monocrystalline silicon , but after annealing at high temperature the mobility turns down 通过测试氢等离子体钝化和氮化硅薄膜钝化的效果，实验还发现氢等离子体处理对多晶硅材料的少子寿命提高作用比较明显，但是这种提高作用与处理温度以浙江大学硕士学位论文王晓泉2003年5月及时间的关系不大；氨化硅薄膜中的氢对单晶硅的载流子迁移率提高有一定作用，但经过高温处理后这种作用消失；氮化硅薄膜能提高单晶硅和多晶硅的少子寿命，具有表面钝化和体钝化的双重作用；氢等离子体和氮化硅薄膜都能有效地提高单晶和多晶电池的短路电流密度，进而使电池效率有不同程度（绝对转换效率0
