Wafer polishing systems

1. Chemical Mechanical Planarization (CMP) technology delivers high-precision global planarization for dielectric, metal, and STI surfaces.

2. Automated operation with cassette-to-cassette handling, recipe control, and integration with fab automation (MES, data systems).

3. Advanced polishing heads & slurry delivery ensuring consistent material removal and surface quality across wafer diameters (100 mm to 300 mm and beyond).

4. Endpoint detection and in-situ monitoring for real-time thickness/planarity control to meet tight tolerance requirements.

5.Dry-in/dry-out cleaning functions reduce contamination, improve throughput, and support high-yield production.

DESCRIPTION

Wafer polishing systems often implemented as Chemical Mechanical Polishing (CMP) machines are precision semiconductor manufacturing tools used in the back end of line (BEOL) process to achieve ultra-flat, defect-free wafer surfaces. These systems remove microscopic topography, planarize dielectric and metal layers, and eliminate surface irregularities introduced by prior deposition and etch steps, enabling reliable lithography and high-yield device performance in advanced packaging and logic/memory applications. CMP machines combine chemical action from slurries with controlled mechanical abrasion to deliver sub-nanometer flatness and uniformity across the wafer surface.
