Abstract: Methods and apparatuses for dispensing polishing fluids onto a polishing pad within a chemical mechanical polishing (CMP) system are disclosed herein. In particular, embodiments herein relate to a CMP apparatus for processing a substrate including a pad disposed on a platen. The pad has a pad radius and a central axis from which the pad radius extends. The apparatus also include a carrier assembly configured to be disposed on a surface of the pad and having a carrier radius that extends from a rotational axis of the carrier assembly and a fluid delivery assembly comprising one or more nozzles, each nozzle coupled to a fast actuating valve.
