چکیده انگلیسی
A high electron density (> 1011 cmâ 3) and low electron temperature (1-2 eV) plasma is produced by using a microwave plasma source utilizing a spoke antenna, and is applied for the high-rate synthesis of high quality microcrystalline silicon (μc-Si) films. A very fast deposition rate of â¼Â 65 Ã
/s is achieved at a substrate temperature of 150 °C with a high Raman crystallinity and a low defect density of (1-2) Ã 1016 cmâ 3. Optical emission spectroscopy measurements reveal that emission intensity of SiH and intensity ratio of Hα/SiH are good monitors for film deposition rate and film crystallinity, respectively. A high flux of film deposition precursor and atomic hydrogen under a moderate substrate temperature condition is effective for the fast deposition of highly crystallized μc-Si films without creating additional defects as well as for the improvement of film homogeneity.
