Chemical Mechanical Wafer Polishing is a process that uses a combination of chemicals and mechanical polishing to remove material from the surface of a semiconductor wafer. The chemical component of CMP reacts with the surface being polished, while the mechanical component removes material through physical abrasion. CMP is a highly controlled process, and variations in the composition of the chemical solution and the type of polishing pad can result in different rates of material removal. In addition, CPA can be used to clean semiconductor surfaces by removing particles that could otherwise cause defects in the finished product.

Control Systems Used For Semiconductor Wafer Polishing
How are silicon wafers polished?
Silicon wafers are polished to create a flat, smooth surface that is essential for semiconductor manufacturing. Polishing removes any irregularities from the wafer surface and helps to create a mirror-like finish. There are two main types of polishing: chemical-mechanical polishing (CMP) and physical vapor deposition (PVD). CMP involves using a chemical solution to remove material from the surface of the wafer, while PVD uses a physical process to deposit thin films onto the wafer surface. Silicon wafers are typically polished using CMP, as this method can achieve a higher degree of accuracy and precision.
