In this work, the thermo-optic coefficient (TOC) of the silicon-rich amorphous silicon carbide (a-SiC) thin film deposited by plasma-enhanced chemical vapor deposition (PECVD) was characterized. We found that the TOC of the film increases as its silicon content increases.
半导体“等离子增强化学气相沉积(PECVD)”工艺技术的详解;
等离子增强化学气相沉积,英文全称:Plasma Enhancd Chemical Vapor Deposition,简称:PECVD,它是半导体行业中常用的一种薄膜沉积技术。 这种技术结合了化学气相沉积(CVD)的基本原理与等离子体技术,可以生产高品质的薄膜并精确地控制其属性。 区别于传统的CVD技术,PECVD通过使用等离子体来提高沉积效率,使其能在更低的温度条件下进行材料沉积。 在PECVD技术中,使用低气压下的低温等离子体在沉积室的阴极触发辉光放电。 此过程或 …
