摘要:A method for manufacturing a semiconductor device includes the steps of:forming a trench in a substrate; forming a conductive film in the trench through an
insulation film; and annealing the substrate at an annealing temperature after the step offorming the conductive film so that a damage in the insulation film is removed at theannealing temperature. The device
