Study of the Sputtered Mo/TaN and Mo-Ta Thin Film as Diffusion Barrier for Copper Metallization
In this work, the properties of sputtered Mo/TaN bilayers and Mo-Ta single layer as diffusion barriers were investigated for Cu metallization. The experimental results show that the Mo(5nm)/TaN(5nm) stack can withstand annealing up to 600 ℃ for 30min and the Mo-Ta(5nm) alloy barrier can effectively prevent Cu diffusion after 500 ℃ annealing.
