    Abstract: A chemical mechanical polishing chamber may include a platen disposed within the chemical mechanical polishing chamber, the platen configured to support a polishing pad. The chamber may also include a slurry delivery arm configured to deliver a slurry to the polishing pad during a chemical mechanical polishing process. The chamber may include an arm may include one or more brackets, mechanically attached to an internal side of the chemical mechanical polishing chamber and positioned over the platen. The chamber may include a plurality of nozzles configured to deliver a gas to the polishing pad, the plurality of nozzles mechanically attached to the one or more brackets of the arm, each of the plurality of nozzles oriented such that an air gap is disposed between adjacent nozzles of the plurality of nozzles such that air may be pulled from the air gap and propelled with the gas towards the polishing pad.

    Abstract: Apparatus and methods relating to chemical mechanical polishing (CMP) are described herein. An edge load ring (ELR) is configured to fit inside a retaining ring of a CMP head. The ELR includes an annular body having an inner surface and an outer surface opposite the inner surface, the outer surface having a diameter configured to slip inside a retaining ring. The annular body includes a body portion formed from a first material and a bottom projection extending below the body portion. The bottom projection has a bottom surface facing away from the body portion, and the bottom projection is formed form a second material different from the first material. The annular body includes a venting feature formed through the annular body, the venting feature being in fluid communication between the inner and outer surfaces.

    Abstract: A method is provided to minimize travel distance and time between correction locations on a substrate when polishing a local area of a substrate, such as a semiconductor wafer, using a location specific polishing module. A correction profile is determined and a recipe based on the correction profile is used to polish a substrate. A polishing pad assembly traverses between a first correction location and a second correction location using the combined motion of a substrate support chuck and a support arm coupled at a first end thereof to the polishing pad assembly. The chuck rotates about a center axis thereof. The positioning arm may sweep about a vertical axis disposed through a second end of the support arm. The combined motion of the chuck and the positioning arm causes the polishing pad assembly to form a spiral shaped polishing path on the substrate.
