Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a semiconductor device where in order not to make the thickness of an insulating film different by concentration of a trench isolating part, thickness of an insulating film in the trench is prevented from changing between patterns, without deteriorating burying property of the insulating film to the trench isolating part, when the insulating film buries in the trench isolating part is flattened by polishing, and difference of film thickness in the whole region of an Si substrate between the same patterns can be excluded. SOLUTION: An SiO2 insulating film 9 is polished with abrasive whose main component is CeO2 , a polishing stopper upper layer film 8 constituted of a poly Si film is exposed. At this time, the polishing speed of the poly Si film is low in the above abrasive, and the poly Si film acts as a polishing stopper. The poly Si film and the SiO2 film are polished by using alkaline abrasive whose main component is silica. The polishing speed of the poly Si film is the highest, and the polishing speed of a polishing stopper lower layer 7 constituted of SiN is the lowest when the alkaline abrasive is used. As a result, the poly Si film 8 used as a stopper in a first step of polishing can be selectively polished, so that pattern dependency of polishing is canceled, and the whole surface can be flattened.
