Example Embodiment

[0028] Hereinafter, the present invention will be further described with reference to the drawings and specific embodiments.

[0029] A groove grinding disc, reference Figure 1 to 2 , The grinding disc is provided with a groove; the groove is formed by coupling a plurality of concentric circular grooves 1 with a gradually expanding radius and a plurality of spiral grooves 2 arranged at equal intervals; the center of the spiral groove 2 Concentric with the center of the concentric groove 1; the grinding disc is divided into a first area 3, a second area 4, and a third area 5 along the radial direction from the inside to the outside; the first area 3 and the third area 5 The distance between the concentric grooves 1 is greater than the distance between the concentric grooves 1 of the second region 4. The diameter of the surface of the grinding disc is 300 to 2000 mm. The concentric circular groove 1 and the spiral groove 2 have a rectangular cross-sectional groove shape, or a pe...

Abstract

The invention provides a groove grinding disc and a method for manufacturing the groove grinding disc. The grinding disc is provided with a groove; the groove is formed by coupling a plurality of concentric grooves with radii gradually increasing and a plurality of spiral line grooves which are arranged at equal intervals; the centers of the spiral line grooves are concentric with the centers of the concentric grooves; the grinding disc is divided into a first area, a second area and a third area from inside to outside in the radial direction; and the distance between the concentric grooves ofthe first area and the distance between the concentric grooves of the third area are greater than the distance between the concentric grooves of the second area. The application of the technical scheme can realize the improvement of the flow performance of grinding liquid in the grinding and polishing process, and the problems of blockage and wear of the grinding disc are obviously improved.

Description

technical field [0001] The invention relates to the technical field of grinding and polishing, in particular to a grooved grinding disc and a method for manufacturing the grooved grinding disc. Background technique [0002] With the rapid development and wide application of semiconductor technology, the processing of semiconductor materials is becoming more and more precise. Grinding and polishing, as an important processing method in precision and ultra-precision processing, plays a key role in the semiconductor manufacturing process because of its high processing accuracy. [0003] In recent years, with the continuous increase of wafer size and the continuous improvement of surface quality requirements, grinding and polishing technology is facing higher requirements and challenges. The traditional free abrasive grinding and polishing technology is no longer suitable because of its low processing efficiency, high environmental pollution, and poor surface accuracy caused by...
