The Properties of Low Hydrogen Silicon Thin Films Deposited by Mesh-type PECVD
Published online by Cambridge University Press: 17 March 2011
Abstract
We propose a mesh-type PECVD to minimize the hydrogen concentration in this study. Since in this system deposition rate is very slow, so for increasing a deposition rate, we suggest an applied DC bias enhanced sputtering process. We investigated several conditions to compare with conventional PECVD. Excimer-laser melting and regrowth of thin a-Si films is for fabricating polycrystalline-Si (poly-Si). Furthermore, we fabricate poly-Si thin-film transistor(TFTs) and measure threshold voltage (V), field-effect mobility (cm2 /Vs) and on/off current ratio
