摘要 通过PECVD法,用玻璃作衬底在30℃、350℃和450℃下直接沉积非晶硅(a-Si:H)薄膜,在600℃和850℃下退火三个小时,把前后样品用拉曼光谱和XRD分析,发现二次晶化后的晶化效果比直接沉积的薄膜好,850℃下退火的薄膜比600℃下好。 Undoped amorphous silicon film deposited by PECVD at different substrate temperature 30 ℃ ,350 ℃ ,450 ℃ , and annealed at 600 ℃ and 850 ℃ in a N2 atmosphere was studied by using micro-Raman scattering and XRD. It can be seen that the crystallization is better at 850 ℃ than that at 600 ℃.
