Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0035] Unless otherwise defined, all technical and scientific terms used in this utility model have the same meaning as those commonly understood by technicians in the technical field of this utility model. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used in this utility model includes any and all combinations of one or more related listed items.

[0036] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] Hard and brittle materials refer to materials with high hardness and high brittleness, usually including glass, ceramics, stone and semiconductor crystal materials. Especially for hard and brittle materials with Vickers hardness above 1500Hv, such as diamond, aluminum oxide (sapphire), silicon carbide, boron carbide, zirconium carbide, tungsten carbide, silicon nitride, titanium nitride, gallium nitride, their chemical properties are very stable, reactivity is low, hardness is also very high, and processing is extremely difficult. In industrial production, in order to obtain such material substrates with high surface quality, chemical mechanical polishing (CMP) technology is introduced to improve material removal rate and minimize surface damage.

[0038] CMP technology is an ultra-precision polishing technology based on the combination of chemical and mechanical effects of polishing liquid. The polishing pad is adhered to the polishing disc and rotates at a certain angular velocity. At the same time, the polishing workpiece is adhered to the polishing head holder and rotates at a certain angular velocity. Under the chemical action of the polishing liquid, an oxidized softening layer is generated on the surface of the wafer, which is removed under the mechanical action of the abrasive particles, thereby achieving the flattening of the workpiece surface. At present, in the CMP processing of such hard and brittle materials, in order to ensure sufficient removal rate, a polishing liquid containing high-hardness abrasives such as diamond and aluminum oxide is selected. However, this type of abrasive has poor dispersibility, is very easy to agglomerate and settle, and is easy to scratch the surface of the workpiece to be polished, resulting in substandard surface quality.

[0039] The mainstream abrasive stirring device on the market is mainly designed to adjust the stirring blades to disperse the abrasive circulating back during the polishing process and reduce the abrasive agglomeration and precipitation. However, in actual processing, the stirring rate of the stirring blades is relatively low, the mechanical dispersion force generated is weak, and the abrasive dispersion ability is poor, so the abrasive is easy to agglomerate and precipitate, resulting in a reduced removal rate, increased scratches, and substandard wafer surface quality. Therefore, a device to improve abrasive dispersion is needed to improve the above problems.

[0110] The working principle of an abrasive dispersing device 100 is introduced below.

[0111] When the abrasive dispersion device 100 is working, the material first enters the first bin 311 through the feed port 321, and the driving member 50 drives the first rotating shaft 40 and the first blade 61 and the stirring rod 62 connected thereto to rotate and stir, thereby reducing the agglomeration and sedimentation of the material. As the material falls under the action of gravity, the agglomerated material enters between the fixed block 13 and the grinding block 122 through the first hole 112 of the fixed plate 111, and the first rotating shaft 40 drives the rotating plate 121 to rotate, thereby driving the grinding block 122 to rotate, thereby grinding the agglomerated material. Afterwards, the material falling on the bottom of the second bin 312 is further vibrated and crushed by the vibration of the ultrasonic component 20, and enters the lifting bin 33 from the inlet 331. The second rotating shaft 71 rotates under the belt drive of the first rotating shaft 40, driving the second blade 72 to rotate, and lifting the material into the first bin 311 for mixing again. After the mixing is completed, the material in the first bin 311 is discharged through the first discharge port 34, and the material in the second bin 312 is discharged through the second discharge port 35.
