Patent ID: 8821219

Claim:
A wafer processing system, the wafer processing system comprising: an upper plate polishing pad; a lower plate polishing pad, whereby a wafer is disposed and processed between the upper plate and lower plate polishing pad; and a wafer unloading structure in which a fluid is supplied between the lower plate polishing pad and the wafer; a lower plate disposed under the lower plate polishing pad; wherein the wafer unloading structure includes: a fluid supply tube for supplying the fluid, a nozzle for injecting the supplied fluid, an injection hole defined in the lower plate polishing pad to allow the injected fluid to reach a space between the lower plate polishing pad and the wafer; and a nozzle tube through which the injected fluid is movable into the injection hole, wherein the fluid supply tube, the nozzle and the nozzle tube are disposed in the lower plate, wherein the injection hole is defined in the lower plate polishing pad to correspond to the nozzle tube of the lower plate.
