摘要 本文用PECVD法在石英玻璃上沉积非晶硅薄膜,然后用快速光退火和传统电阻炉退火方法晶化生长多晶硅薄膜,用拉曼光谱仪、XRD和场发射扫描电镜观察分析薄膜,发现在制备的多晶硅薄膜表面存在结晶团现象,并对这一现象的晶化机理进行了分析。 Undoped amorphous silicon film deposited by PECVD on quartz glass, and annealed by rapid thermal annealing (RTA) and furnace annealing (FA) respectively, the films were characterized by Rarnan spectra, X-ray diffraction ( XRD ) and scanning electronic microscope ( SEM ) respectively. It could be found phenomenon of crystal group in fabricating poly-Si thin film. The formation mechanism of the phenomenon has been studied.
