FIG. 1 is a partially enlarged sectional view of a polishing pad 20 for a mechanochemical polishing apparatus. As shown in the figure, the polishing pad 20 is configured by laminating a polishing member layer 22 and a backing layer 24 with an adhesive sheet 26. A window 28 is provided in a part of the polishing pad 20, and the backing layer 24 is removed in the window 28. Further, in the window portion 28, the polishing member layer 22 corresponding to the window material 30 is replaced with a polishing pad made of another material.

The window portion 28 is provided at at least one location on the polishing pad 20. Then, from the lower surface of the window 28, the end point is detected during the CMP process by the method described later. Further, in the illustrated configuration, the polishing member layer 22 corresponding to the window material 30 is replaced with a polishing pad made of another material. The reason for this is that if a polishing pad having a polishing performance close to that of the polishing member layer 22 and having a higher light transmittance than the polishing member layer 22 is used as the window material 30, the end point detection during CMP processing can be further improved. This is because it can be done reliably.

However, as long as the polishing member layer 22 is made of a material and has such a light transmittance that the end point can be detected during the CMP process, the polishing member layer 22 is necessarily replaced with a polishing pad made of another material. No need. In this case, the polishing pad 20 can be made simpler than the structure shown in FIG. Further, as a matter of course, if the polishing member layer 22 is a translucent member, it is not necessary to provide the window 28.

In the configuration of FIG. 1, a polyethylene terephthalate sheet is used as the adhesive sheet 26, but the adhesive sheet 26 is not limited to this, and various sheet materials can be used. For example, polyethylene, polypropylene, Vespel (trade name) and the like can be used.

By using such an adhesive sheet 26, the slurry that has penetrated into the polishing member layer 22 during the CMP process leaks below the polishing member layer 22 and is used in a laser used in the end point detecting means described later. It is possible to prevent the interferometer 32 and the like from being contaminated.

In the window portion 28, the adhesive layer on the lower surface of the polyethylene terephthalate sheet is not removed and remains. This is because even if there is an adhesive layer on the lower surface of the sheet, the decrease in light transmittance is slight and the end point can be detected during CMP processing. However, if the adhesive layer on the lower surface of the sheet can be easily removed, it is desirable to remove it.

A laser interferometer 32 is arranged at a predetermined position below the polishing platen 12. Then, the laser beam 34 from the laser interferometer 32 is applied to the window portion 28, and the laser beam reflected through the window portion 28 is arranged to return to the laser interferometer 32. However, since the polishing platen 12 rotates, the measurement is performed only when the window 28 comes directly above the laser interferometer 32 due to the rotation of the polishing platen 12.
