Description of the invention (2) The grinding device constituted above is a rotating plate 1 1 and a grinding agent 1 5, the polishing cloth 12 supplied, while pushing the semiconductor substrate 1.3 toward the polishing cloth 12 by the substrate holding head 14, rub the surface of the semiconductor substrate 13 at this time. At this time, there are uneven portions on the surface of the semiconductor substrate 13 At this time, in the convex portion of the semiconductor substrate 13, the polishing speed is increased due to the larger contact pressure with the polishing cloth 12. On the one hand, in the concave portion of the semiconductor substrate 13, the contact pressure with the polishing cloth 12 is increased. It becomes smaller and the polishing speed becomes slower. Therefore, the uneven portion on the surface of the semiconductor substrate 13 is relaxed and the surface of the semiconductor substrate 13 is made flat. This polishing technique is introduced, for example, in "January 1984 January" "Semiconductor World" _5_8 to 5 9 pages, _ or "/, So 1. id State Technology" _Guly, 1992 / Japan. Local version 3 2 to 37 pages, etc. Problems to be solved] However, the above-mentioned grinding device has the following problems. Printed by the Central Standards Bureau of the Ministry of Economic Affairs, printed by the Shelley Consumers' Cooperative. The supply of abrasives and the grinding rate are explained; As the supply of honing agent 15 increases, it becomes constant at a certain supply amount. Therefore, generally, an amount of abrasive 15 that is slightly larger than the supply rate with a certain polishing rate is supplied on the polishing cloth 12 However, as described above, since the abrasive cloth 15 is rotated on one side and the abrasive agent 15 is supplied on one side, the abrasive agent 15 flows to the outside of the abrasive cloth 12 due to the centrifugal force following the rotation of the platen 11. When the amount of Abrasive 1 5 is less than the specified amount *, the grinding rate will be reduced * In order to make up for the reduction of the grinding rate, the paper size will be increased by applying the Chinese National Standard (CNS) A4 specification (210X297 mm) 5 4 ^ 59 A7 B7. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention (3) The pressure to push the semiconductor substrate 13 to the polishing cloth 12 is fine, but problems such as deterioration of the polishing characteristics occur. Therefore, Must be supplied often A slightly larger amount of abrasives than a certain rate of supply becomes a certain amount of abrasives, and the abrasives account for most of the cost of grinding. Thus, as shown in U.S. Patent No. 4,910,155, it is proposed to use a partition board to surround The surrounding of the polishing cloth prevents the abrasive from flowing out, and becomes a polishing device and a polishing method that do not flow out of the abrasive from the polishing cloth. However, according to the polishing device and the polishing method, it is not necessary to wait for the polishing cloth to occur. Objects are stored on the abrasive cloth. In addition, when washing the polished semiconductor substrate on a polishing cloth or trimming (adjusting the surface of the polishing cloth), if water is supplied to the polishing cloth, the water will not be removed from the polishing cloth like the abrasive. Outflow. Due to these, a new problem arises in that the concentration of the abrasive changes, and the polishing characteristics change. In view of the above, the object of the present invention is that the cleaning liquid on the abrasive cloth supplied is discharged from the abrasive cloth, but the abrasive supplied to the abrasive cloth is held on the abrasive cloth. ..... [Methods used to solve the problem] In order to achieve the above-mentioned purpose, the solution adopted by the invention in the first scope of the patent application is a polishing device for semiconductor substrates, which is characterized by having a flat surface and A fixed plate rotating around the vertical axis of the flat surface as a center, a polishing cloth placed on the flat surface of the fixed plate, and a abrasive supply means for supplying an abrasive on the above-mentioned polishing cloth, and maintaining a half- -----—! — 丨 Installation ------- Order ------ Line ··.

Description of the invention (cloth 1 2-Rotation is the principle. As a result, the abrasive 15 is pushed back to the center of the fixed plate 1 1. In the embodiment, as a rule, the abrasive holding member 19 is rotated together with the abrasive cloth 12, and thus the abrasive 15 is stored on the abrasive cloth 12. That is, the abrasive is supplied from the abrasive supply pipe 16 to the abrasive. The abrasive on the cloth 12 and the centrifugal force following the rotation of the platen toward the outside of the platen 1 1 15 are moved against the abrasive holding member 19 to change the flow direction, and are stored on the cloth 12 Therefore, in a state of being spread on the polishing cloth 12, the polishing is supplied to the semiconductor substrate 13. The length and angle of the abrasive holding member 19 are appropriately selected from the polishing agents that can be used on the polishing cloth 12 1 5 is held on the polishing cloth 12. If the holding members 19 adjacent to each other are overlapped with each other in the radial direction of the fixed plate 11, the abrasive 15 is held more reliably.
