What are CMP Point-of-Use Filters?
Point-of-use filters are installed directly at the CMP tool to remove particles, gels, and contaminants from slurries and post-CMP cleaning solutions. By eliminating impurities right before the slurry contacts the wafer, these filters reduce scratches, defects, and yield losses in semiconductor devices.
Key features include:
- Ultra-high particle retention efficiency
- Compatibility with abrasive slurries and chemicals
- Long service life to reduce downtime
- Ability to withstand high flow rates and pressures
These qualities make POU filters essential for ensuring process stability in semiconductor fabs.
