Abstract: A method for fabricating a semiconductor device that prevents the occurrence of bowing and thickness reduction in a dual damascene method. As shown in FIG. 2(B), silicon nitride etching is performed on a semiconductor device in process of fabrication which has a section shown in FIG. 2(A). As a result, part of a copper film is oxidized and changes into oxide. Moreover, a CFx deposit is formed on it. By performing organic insulating film etching by the use of hydrogen plasma in FIG. 2(C), however, the oxide is deoxidized to copper and the CFx deposit is converted into a volatile compound and is removed.
