Abstract:
A method of manufacturing a semiconductor device, comprising forming wiring and interlayer insulating film on a substrate on which a semiconductor element is formed,wherein polishing is effected by the use of a precision polishing apparatus after a film, which becomes the wiring or the interlayer insulating film, is formed, andwherein the precision polishing apparatus comprises a polishing unit having polishing means for polishing the film which is formed on the substrate, a removing unit for removing a stain on a polished surface of the film which is formed on the substrate transported from the polishing unit, detecting means for detecting a state of the polished surface of the film which is formed on the substrate operated upon the removing unit, and selectively returning means for selectively returning the film which is formed on the substrate to the polishing unit or the removing unit in conformity with the result of the detection by the removing unit in conformity with the result of the detection by the detecting means.
