钝化表面 meaning in English

passivated surface
passive surface

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。
The influence of sinx deposited by pecvd in different condition , especially changing deposition temperature , on the gaas surface after sulfur passivation is measured by sims analysis combined with the test for direct current breakdown characteristics
用sims分析结合器件直流特性测试，比较了在不同条件下淀积的氮化硅对gaas硫钝化表面的作用，特别是淀积温度分别为80 、 80 / 230 、 230时对硫钝化效果的影响。
