薄起始层的VHF PECVD底栅微晶硅薄膜晶体管
A VHF PECVD Micro-Crystalline Silicon Bottom Gate TFT with a Thin Incubation Layer
摘要
Abstract
The incubation layer with amorphous structure between the substrate and crystalline layer may obviously affect the performance for a microcrystalline Si thin film transistor (μc-Si TFT) ,especially for the bottom gate TFT (BG-TFT). It is found that decreasing the ratio of SiH4/(H2 +SiH4) is an effective way to decrease the incubation layer thickness of μc-Si directly deposited by VHF PECVD without any further thermal or laser treatment. Based on the μc-Si with a thin incubation layer, the BG-TFT with Al/SiNx/μc-Si/n+ -μc-Si/Al structure is fabricated. The ravoltage is about 5V.关键词
