二、主要优势
Major advantages
1、可在不破真空情况下实现硅片双面的i/n、i/p四层薄膜的连续制备;
2、无绕镀问题;
3、特殊设计延长热丝寿命;
4、与现行产线i/n和i/p非晶硅薄膜需分两台装备完成相比,可节省一组unload/load 腔和上下料自动化;
5、产能扩展空间大。
l Bifacial continuous deposition of i/n and i/p a-Si:H films
l Free of round deposition problem
l Prolonged hot wire life through a special design
l Saving a set of unload/load chambers and automation, compared with other current models, which requires two sets of CVD to perform i/n and i/p a-Si:H films respectively
l Good scalability
