Abstract: A method and apparatus for dispensing polishing fluids and onto a polishing pad within a chemical mechanical polishing (CMP) system are disclosed herein. In particular, embodiments herein relate to a CMP system with a first fluid delivery arm and a second fluid delivery arm disposed over the polishing pad to dispense fluid, such as a polishing fluid or water, and/or provide a vacuum pressure. The second fluid delivery arm is configured to dispense a fluid or vacuum pressure onto the polishing pad to effect the polishing rate at the edge of the substrate.
