    Abstract: Embodiments of the disclosure provided for a pad conditioner with multiple disks for chemical mechanical polishing. The pad conditioner includes a bearing ring connected to a lower portion of a shaft, an outer disk assembly connected to the lower portion of the shaft, the outer disk assembly, an outer disk flexure, a plurality of outer disks disposed on a bottom surface of the outer disk, and an inner disk assembly. Alternatively, the outer disk assembly includes a plurality of outer disk holders, an outer disk connector connecting the plurality of outer disk holders, and a plurality of outer disks disposed on a bottom surface of the outer disk holders. The inner disk assembly includes a flexure connected to the outer disk assembly, the inner disk assembly, and the shaft. The pad conditioner may include a spherical bearing assembly coupled to a lower portion of the shaft.

    Abstract: A method of processing a substrate, includes placing a front surface of a substrate disposed in a carrier head on a polishing surface of a pad. The method further includes delivering a first fluid onto the polishing surface using a first fluid delivery arm. The method further includes determining a location of a hot spot on the front surface. The method further includes determining a rotational orientation of the substrate relative to the carrier head. The method further includes treating the hot spot while polishing the front surface on the polishing surface using a second fluid delivery arm to deliver a second fluid to the polishing surface at a location that will intersect with the hot spot during polishing of the front surface of the substrate.
