2. Description of the Related Art Precision polishing of a thin brittle material such as a semiconductor wafer and glass is carried out, for example, in Japanese Utility Model Application Laid-Open No. 60-161551.
This is performed by a polishing machine called a lapping machine as shown in FIG. 1 to FIG. In such a polishing operation, a carrier that is a disk-shaped thin plate, on the outer periphery of which teeth meshing with the internal and external gears of the lapping machine are formed, and through holes for holding an object to be polished are formed. A plate is used. Conventionally, a thin metal plate has been used as a carrier plate. However, there has been a problem that minute debris, rust, etc. of the carrier plate generated at the time of polishing have an adverse effect on the object to be polished. In addition, there is a problem that plastic deformation tends to occur due to a drop or collision during transportation, and polishing using a deformed carrier plate lowers the polishing accuracy of an object to be polished. Therefore, a carrier plate made of fiber reinforced plastic (FRP) which is chemically stable and hardly deformed plastically has been used.

Such an FRP carrier plate is disclosed in JP-A-58-143954 and JP-A-58-186571, which are obtained by weaving reinforcing fibers such as carbon fibers. A carrier plate made of a thin FRP sheet reinforced by a reinforcing fiber cloth is disclosed. However, in this carrier plate, the material of the carrier plate was simply changed from metal to fiber reinforced plastic, and the strength of the tooth portion was insufficient. Therefore, Japanese Patent Application Laid-Open No. 63-221968 discloses a carrier plate in which reinforcing fibers are arranged along the outer shape of the teeth to reinforce the teeth cut on the outer periphery of the FRP carrier plate. This carrier plate is
It was developed to compensate for the lack of strength in the teeth,
In the same manner as described above, since only metal was changed to fiber-reinforced plastic and no consideration was given to the advantages and disadvantages of the anisotropic material inherent to fiber-reinforced plastic, even a single carrier plate has its teeth. Each had a variation in rigidity. In particular, the teeth near the through-hole that holds the object to be polished are particularly low in rigidity due to their shape, so they are deformed during polishing, causing intensive wear and damage, and the life of the carrier plate is reduced. Was shortened.

Another cause of shortening the service life is a V-shaped groove formed on the side surface of the through hole of the carrier plate by polishing. The V-shaped groove not only causes breakage, but also hinders uniform polishing because an object to be polished is caught in the groove during polishing. The V-shaped groove is formed along the wall of the through-hole because the polished object rubs against the polished object, and an abrasive or polishing debris intrudes between the polished object and the side surface of the through-hole, This is more noticeable when the object to be polished is chamfered to improve the polishing uniformity.

[0005] These are for a single carrier plate that determines the length of life for each carrier plate, but the life of the carrier plate cannot be simply increased by solving the problem. Conventionally, even if the carrier plates are of the same type, the durability thereof is not constant and the dispersion is extremely large. In addition, many thin brittle materials such as semiconductor wafers and glass that are precisely polished by a lapping machine are expensive, and a failure occurs in the carrier plate during the polishing operation, resulting in poor polishing or damage to the carrier plate. Poor polishing or contamination of the object to be polished leads to enormous damage. Therefore, in practice, all the carrier plates are replaced on the basis of the one having the shortest life, in order to ensure completeness. As a result, the life of the carrier plate is considered to be very short. SUMMARY OF THE INVENTION It is an object of the present invention to provide a carrier plate that solves the above-mentioned problems and has improved durability and short life, which are problems with the conventional carrier plate.
