CMP
CMP, which stands for Chemical Mechanical Planarization (or Polishing), is a crucial process in making computer chips and electronic components. Think of it like fine-grain sandpaper that makes surfaces extremely flat and smooth. When manufacturers create modern electronics, they need to build many layers of materials, and each layer must be perfectly flat - just like making a perfectly level sandwich. CMP helps achieve this flatness using a combination of special chemicals and very precise polishing. This process is essential in making all kinds of electronic devices, from smartphones to computers.
