Silicon wafers are the foundation of integrated circuits and semiconductor devices. They have an interesting feature - flat edges or tiny grooves on the sides .It is not a defect, but a deliberately designed functional marker.In fact, this notch serves as a directional reference and identity marker throughout the entire manufacturing process.

Chemical mechanical polishing (CMP) removes excess material and surface defects through the combined action of chemical reactions and mechanical abrasion. It is a key process for achieving global planarization of the wafer surface and is indispensable for multilayer copper interconnects and low-k dielectric structures. In practical manufacturing

Silicon wafer CMP (Chemical Mechanical Planarization) polishing slurry is a critical component in the semiconductor manufacturing process. It plays a pivotal role in ensuring that silicon wafers—used to create integrated circuits (ICs) and microchips—are polished to the exact level of smoothness required for the next stages of production

In semiconductor manufacturing, Chemical Mechanical Planarization (CMP) plays a vital role. The CMP process combines chemical and mechanical actions to smooth the surface of silicon wafers, providing a uniform foundation for subsequent steps such as thin-film deposition and etching. CMP polishing slurry, as the core component of this process, significantly impacts polishing efficiency, surface quality, and the final performance of the product

Wafer CMP polishing slurry is a specially formulated liquid material used in the CMP process of semiconductor manufacturing. It consists of water, chemical etchants, abrasives, and surfactants, enabling both chemical etching and mechanical polishing.

Silicon carbide abrasives are typically produced using quartz and petroleum coke as primary raw materials. In the preparatory stage, these materials undergo mechanical processing to achieve the desired particle size before being chemically proportioned into furnace charge.
