梯度α-Ta(N)/TaN扩散阻挡层的微结构与热稳性定
Thermal stability and microstructure of graded α-Ta(N)/TaN bi-layer diffusion barrier
摘要
Abstract
α-Ta(N)/TaN bi-layers diffusion barriers with lower resistance were prepared by a magnetron sputtering method with controlling N2 flow rate forming a transition layer on TaN layer. Four-point probe (FPP), X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used for characterization of the diffusion barriers microstructure before and after annealing The results show that the as-deposited graded α-Ta(N)/TaN bi-layer films have lower resistivity and good crystallinity.and the graded α-Ta(N)/TaN bi-layer diffusion barrier has an excellent thermally stability. Its failure temperature can be up to 800℃.关键词
