In the silicon carbide wafer manufacturing process, in order to ensure the smooth production of high-quality, high-performance products, every step of the operation needs to be very precise. Among them, the grinding and polishing of silicon carbide substrate is particularly important, because it directly affects the quality and performance of the chip. In order to achieve efficient and precise grinding and polishing, selecting the appropriate grinding material is the key. Today, we will discuss the important material of silicon carbide substrate polishing process - diamond grinding fluid.
1. Composition of diamond grinding fluid
Diamond, known for its excellent hardness and wear resistance, has an indispensable position in the field of grinding and polishing. Diamond grinding liquid is mainly composed of diamond powder, dispersant, suspension agent and lubricant. Among them, diamond powder is used as the main abrasive to physically grind the silicon carbide substrate. Dispersants and suspensions ensure that the diamond particles in the grinding fluid are evenly dispersed and prevent agglomeration. The lubricant reduces friction during grinding and ensures the smoothness and quality of the silicon carbide substrate surface.
2. Advantages of diamond grinding fluid
High efficiency: The high hardness and sharpness of the diamond powder make the grinding process more efficient, and the required flatness and finish can be obtained in a short time.
High precision: Due to the self-sharpness of the diamond and the uniform dispersion of the micro-powder, the wafer can maintain high precision and consistency during the grinding process.

A wide range of adaptability: Different particle sizes of diamond grinding fluids can be applied to different stages of grinding, from coarse grinding to hyperfine grinding, you can find the right product. 3. Zhongji New Material's diamond grinding fluid products
