摘要
The diffusion coefficient of Cu in (Ti, Zr)N was measured by X-ray diffraction (XRD) and four-point probe (FPP) analyses after annealing Cu/(Ti, Zr) N/Si multilayered samples in the temperature range of 500- 900 degreesC. Cu diffusion in (Ti, Zr)N had components from both the grain boundaries and the lattice based on diffusional analysis. This study suggests that for the measurement of the diffusion coefficient of Cu, FPP analysis is more precise and sensitive than XRD analysis. Additionally, (Ti, Zr)N has better Cu diffusion barrier properties than those of TaN and TiN. (C) 2004 The Electrochemical Society.
