A chemical mechanical
polishing apparatus includes: a
polishing disk for holding a
polishing pad; a carrier for holding a substrate against the polishing surface of the polishing pad during a polishing process; a polishing liquid
distributor having a polishing liquid port positioned above the polishing disk to deliver polishing liquid onto the polishing pad; a
temperature control system includes: a
coolant fluid reservoir for containing a
coolant fluid; a thermal controller configured to control a temperature of the
coolant fluid within the coolant fluid reservoir; and a first dispenser having an opening in fluid connection with the coolant fluid reservoir, the opening positioned to be configured to spray atomized coolant directly onto the polishing pad; and a second
distributor having a coolant port in fluid connection with the coolant fluid reservoir, the coolant port positioned above the polishing disk and configured to flow a flow of coolant directly onto the polishing pad.
