Description
AGC delivers slurry and polishing solutions that can be used for CMP processes, by making full use of the integrated production from raw material grain to slurry. To realize multi-layered structures with high levels of flatness, we optimize slurries that meet various applications, such as use for oxidized films and wiring materials.
Product Key Features
- Design and manufacturing of abrasive particles
- Accumulated technology of polishing materials for glasses
- Design and manufacturing of various analyses and chemical liquid
- Polishing material evaluation technology
Chemical Mechanical Polishing (CMP)
Chemical Mechanical Polishing, or CMP, has quickly become an indispensable technique for fabricating integrated circuits. During the CMP process, a wafer surface is polished for planarization using a slurry and a polishing pad. The abrasive particles in the slurry grind against the sample surface, loosening material. The chemicals in the slurry then etch and dissolve the material. This process is designed to remove areas of elevated topography more quickly than the lower areas. Although mechanical grinding alone can achieve a reasonable degree of planarization, chemical etching is necessary to remove the extensive damage from mechanical grinding. Although chemical etching results in a damage-free sample, the process is typically isotropic and does not remove topographical features.
Product Applications
- Ceria slurry for STI/ILD Applications
- Poly-Si film polishing
