A method for manufacturing a semiconductor device includes the steps of forming a first insulation layer on a substrate; forming a damascene pattern in the first insulation layer; conducting a first process for forming metal lines in the damascene pattern; conducting a second process for forming a second insulation layer, having compressive stress greater than tensile stress of the metal lines, on the damascene pattern including the metal lines; forming a passivation layer on the substrate after multi-layered metal lines are formed by the first and second processes; and conducting an annealing process for the substrate including the passivation layer.
