摘要： In one embodiment, a method for cleaning a surface of a polishing pad includes conditioning the polishing pad surface and rotating the conditioned polishing pad surface. The method also includes spraying the polishing pad surface to lift debris from the conditioned polishing pad surface. The method further includes vacuuming the debris from the polishing pad surface downstream from where the condition occurs, wherein downstream is defined by a rotational direction of the polishing pad. In another embodiment, a processing station including a rotatable platen, a substrate carrier head, a polishing fluid delivery system, a conditioner, a spray nozzle, and a vacuum system is provided. The conditioner is disposed between the substrate carrier head and the spray nozzle. The vacuum system is configured to vacuum the polishing pad surface. The vacuum system is downstream from the conditioner, defined by a rotation of the platen.

摘要： A method and apparatus for determining a polishing pad thickness profile are described herein. A set of displacement sensors, including an arm displacement sensor and one or more conditioning disk displacement sensors are utilized to determine the orientation of a conditioning disk and the thickness of the polishing pad. The displacement sensors are non-contact sensors, such as a laser sensor, a capacitive sensor, or an inductive sensor. Once the thickness profile of the polishing pad is determined, one or more process conditions is altered to improve substrate polishing.

摘要： Embodiments herein generally relate to chemical mechanical polishing (CMP) systems and methods for reducing non-uniform material removal rate at or near the peripheral edge of a substrate when compared to radially inward regions therefrom. In one embodiment, a polishing system includes a substrate carrier comprising an annular retaining ring which is used to surround a to-be-processed substrate during a polishing process and a polishing platen. The polishing platen includes cylindrical metal body having a pad-mounting surface. The pad-mounting surface comprises a plurality of polishing zones which include a first zone having a circular or annular shape, a second zone circumscribing the first zone, and a third zone circumscribing the second zone. A surface of the second zone is recessed from surfaces of the first and third zones adjacent thereto, and a width of the second zone is less than an outer diameter of the annular retaining ring.

摘要： Polishing pad cleaning systems and related methods are disclosed. A rotatable platen comprising a polishing pad in combination with a fluid, such as a polishing fluid, contacts a substrate to planarize material at the surface thereof and resultantly creates debris. A cleaning system introduces a spray system to remove debris from the polishing pad to prevent substrate damage and improve efficiency, a waste removal system for removing used spray, used polishing fluid, and debris from the polishing pad, and a polishing fluid delivery system for providing fresh polishing fluid to the polishing pad, such that the substrate only receives fresh polishing fluid upon each complete rotation of the platen. In this manner, within die performance is enhanced, the range of certain CMP processes is improved, scratches and contamination are avoided for each polished substrate and for later-polished substrates, and platen temperatures are reduced.
