摘要

The deposition process for heavily doped hydrogenated microcrystalline silicon (n~+ μc-Si:H) has been developed at 120℃ for use in thin film transistor (TFT) fabrication on plastic substrates. Film characteristics have been studied using grazing incidence x-ray diffraction (GIXD), Raman spectroscopy and Fourier transform infrared (FTIR) spectroscopy. The results show that, at high hydrogen dilution (99 %), power density of 75 mW/cm~2 and low deposition temperature (120℃), the film tends to become more crystalline with increasing deposition pressure from 250 to 900 mTorr. Preliminary optimization resulted in a maximum film crystallinity of 74%.
