摘要
为进一步提高多晶硅薄膜的晶化率,采用真空蒸镀法结合金属铝诱导退火处理在玻璃衬底上制备了掺杂磷的多晶硅薄膜。采用扫描电镜、激光拉曼光谱仪等研究了基板温度对磷掺杂多晶硅薄膜的组织、形貌、晶粒尺寸及晶化率的影响。结果表明:随基板温度升高,薄膜的晶粒大小和晶化率呈先增大后减小的趋势,基板温度为150℃时,晶粒尺寸显著增大,达0.45μm左右,且具有较高的结晶度,薄膜晶化率可高达94.95%。
        Polycrystalline silicon thin films doped with phosphorus were prepared by vacuum evaporation and subsequent aluminum induced annealing treatment on glass substrate. The effects of the substrate temperatureon the structures,morphologies,grain sizes and crystalline volume fraction of the films were analyzed by scanning electron microscopy,X-ray diffraction and Raman spectroscopy,respectively. Results showed that with the increase of substrate temperature,grain size and crystalline volume fraction firstly increased and then decreased. Besides,when the substrate temperature was150 ℃,the grain size increased significantly to 0. 45 μm,and the crystalline volume fraction of the film rose up to 94. 95%.
