Among other things, one or more techniques or systems for particle removal from a semiconductor wafer are provided. Particles, contaminating a semiconductor wafer, have the potential to cause defects, such as scratches into a surface of the semiconductor wafer during chemical mechanical polishing or defocusing during a subsequent lithography stage, for the semiconductor wafer. Accordingly, a mechanic particle cleaner component, such as at least one of a sliver brush roller, a pencil brush, a tape polish, a sonic jet, or a liquid spray component, is configured to apply a mechanical force to an edge region of the semiconductor wafer to detach particles. A chemical particle cleaner component is configured to apply a chemical force to the edge region to detach particles. In this way, particles are removed from the semiconductor wafer before or after chemical mechanical polishing. |
