【摘要】 采用射频磁控溅射在 Pt/Ti/SiO2/Si(100)衬底上制备了钛酸锶钡(BST)薄膜,利用气氛炉对薄膜进行晶化处理,晶化后薄膜的应力采用 XRD 表征.研究其残余应力随退火气氛、退火温度以及退火降温速率变化的趋势,通过对不同后处理工艺参数实验结果的分析,得到较优化的工艺参数,以制备较小残余应力的优质 BST 薄膜.
【Abstract】 (Ba,Sr)TiO3 (BST) thin films were prepared on Pt/Ti/SiO2/Si(100) substrates by RF-magnetron sputtering,And then were annealed in different oxygen ambience,temperature and speed of annealing temperature falling,respectively. The stress change of BST thin films was analyzed by XRD.Through researching the relationships between residual stress and annealing atmosphere,temperature,lowering temperature-speed,we have acquired optimized annealing parameters, and (Ba,Sr)TiO3 (BST) thin films,with lower residual stress and better capability,deposited on Pt/Ti/SiO2/Si(100) substrates have been achieved.
