摘要
Polishing pad cleaning systems employing fluid outlets orientated to direct fluid under spray bodies and towards inlet ports, and related methods are disclosed. A polishing pad in combination with slurry contacts a substrate to planarize a surface of the substrate and remove substrate defects while creating debris. A spray system removes the debris from the polishing pad to prevent substrate damage and improve efficiency. By directing fluid under a spray body to the polishing pad and towards an inlet port, the debris may be entrained in the fluid and directed to an inner plenum of the spray body. The fluid-entrained debris is subsequently removed from the inner plenum through an outlet port. In this manner, the debris removal may reduce substrate defects, improve facility cleanliness, and improve pad efficiency.
