发明名称 Method for manufacturing semiconductor device
摘要 A method for manufacturing a semiconductor device is provided. The method includes forming a wiring pattern made of copper, annealing the wiring pattern in an atmosphere of inert gas, and performing plasma processing on the wiring pattern using a reducing gas after the annealing. A temperature in the plasma processing is equal to or below a temperature in the annealing.

主权项 1. A method for manufacturing a semiconductor device, the method comprising: forming a wiring pattern made of copper; annealing the wiring pattern in an atmosphere of inert gas; and performing plasma processing on the wiring pattern using a reducing gas after the annealing, wherein a temperature in the plasma processing is equal to or below a temperature in the annealing, andwherein the forming of the wiring pattern comprises: forming an electrically conductive film using copper as a material on a first insulating film having an opening and in the opening; andpolishing the conductive film to remove a portion of the conductive film located on the first insulating film,wherein a portion of the conductive film embedded in the opening of the first insulating film becomes the wiring pattern.
