Abstract:
A fluid dispensing fixed abrasive polishing pad comprising:a polishing pad body with a lower surface and upper surface substantially parallel to a plane defined by a diameter and opposite one another with both said lower surface and said upper surface having a fluid dispensing duct, said fluid dispensing duct adapted to permit forced fluid to flow from a surface of said polishing pad body to a wafer, wherein said polishing pad body permits said fluids to flow at a force sufficient to remove waste from the surface of a wafer and said polishing pad body during a polishing process, including permitting a flow sufficient to force contaminant waste particles out of said fluid dispensing ducts; and a fixed abrasive component coupled to said polishing pad body, said fixed abrasive component adapted to remove a portion of said wafer when rubbed against a surface of said wafer, wherein said fixed abrasive components do not require assistance from abrasive particles in an abrasive slurry and wherein said abrasive component further comprises abrasive particles coupled to said upper and lower surface of said polishing pad body in a uniform and densely distributed manner over said upper and lower surface, and said flow of said fluid is sufficient to force contaminant waste particles out of a space around said fixed abrasive component.
