A semiconductor integrated circuit device has a semiconductor chip, interposer, and substrate. The semiconductor chip has a plurality of first pads arranged at first pitches on a surface. The interposer has a first surface and a second surface. On the first surface, a plurality of second pads are arranged at the first pitches. On said second surface, a plurality of third pads arranged at second pitches which are larger than the first pitches. The second pads and the first pads are connected to each other by joining the first surface of the interposer to the surface of the semiconductor chip so as to face each other. The substrate has a plurality of fourth pads arranged at the second pitches on a surface. The fourth pads and the third pads are connected to each other by joining the surface of the substrate to the second surface of the interposer so as to face each other.

A improved dresser for dressing a polishing surface, easily be manufactured such that an object to be polished is not scratched when the object is polished. The dresser can dress the polishing surface of a polishing apparatus to effect surface correction and to correct a time-lapse change due to a polishing operation, a number of spired projections are formed on a surface of a metallic substrate and a wear-resistant hard film is formed on at least a portion of the surface of the metallic substrate on which the projections are formed.

In the CMP of films of semiconductor devices, pulsed measuring radiation is directed onto a surface to be polished of a rotating wafer. At this point, the pulse repetition rate of the pulsed measuring radiation is determined so that the pulse measuring radiation is directed only onto a specified portion of the surface of each semiconductor device. Thereby, reflection data can be obtained only from the specified portion of a film to be polished, allowing accurate measurements of the thickness of the specified portion of the film in the middle of polishing.
