硼碳氮薄膜的内应力研究
Inner Stress of Boron Carbon Nitride Thin Films
【摘要】 采用射频磁控溅射技术制备出硼碳氮(BCN)薄膜。傅里叶红外吸收光谱(FTIR)测量发现样品的组成原子之间实现了原子级化合,扫描电子显微镜(SEM)测量发现样品与衬底间存在较大的内应力。样品剥落后,应力的消除使红外吸收峰向低波数移动。实验还发现,对新制备的硼碳氮薄膜进行600℃热处理能有效释放薄膜中的压应力。
【Abstract】 Boron carbon nitride(BCN) thin films were deposited by radio frequency(RF) magnetron sputtering.Fourier transform infrared absorption spectrum(FTIR) measurement shows that B,C and N three type atoms have finished atomic-level hybrid and there is a larger inner stress between the films and substrate.When the films were peeled off from the substrate,stress relaxed and the FTIR absorption peaks shifted to lower wave numbers.Also,annealing at 600℃ is a feasible method to relax the stress for newly deposited.
