    Abstract: According to one embodiment, there is provided a top ring for holding a substrate. The top ring comprises a substrate supporting surface, a retainer member disposed to surround an outer periphery of the substrate supporting surface, and a retainer guiding device configured to guide the retainer member so as to allow the retainer member to be displaced in a direction perpendicular to the substrate supporting surface, and support the retainer member so as to inhibit the retainer member from being displaced in a direction parallel to and away from the substrate supporting surface. The retainer guiding device is disposed in an inner side of the retainer member surrounding the substrate supporting surface.

    Abstract: There is disclosed a substrate processing apparatus which can align a center of a substrate, such as a wafer, with a central axis of a substrate stage with high accuracy. The substrate processing apparatus includes: an eccentricity detector configured to obtain an amount of eccentricity and an eccentricity direction of a center of the substrate, when held on a centering stage, from a central axis of the centering stage; and an aligner configured to perform a centering operation of moving and rotating the centering stage until the center of the substrate on the centering stage is located on a central axis of a processing stage. The aligner is configured to calculate a distance by which the centering stage is to be moved and an angle through which the centering stage is to be rotated, based on an initial relative position of the central axis of the centering stage with respect to the central axis of the processing stage, the amount of eccentricity, and the eccentricity direction.

    Abstract: A polishing apparatus capable of forming a step-shaped recess having a right-angled cross section in an edge portion of a substrate, such as a wafer, is disclosed. The polishing apparatus includes: a substrate rotating device configured to rotate the substrate about a rotation axis; a first roller having a first circumferential surface configured to press a polishing tape against the edge portion of the substrate; and a second roller having a second circumferential surface in contact with the first circumferential surface. The second roller has a tape stopper surface that restricts movement of the polishing tape in a direction away from the rotation axis. The tape stopper surface is located radially outward of the first circumferential surface.

    Abstract: Provided is a top ring that ensures uniformly pressing a substrate against a polishing pad. A top ring 302 for holding a substrate WF includes a base member 301 coupled to a top ring shaft 18, an elastic film 320 that is mounted to the base member 301 and forms a pressurization chamber 322 for pressurizing the substrate WF between the base member 301 and the elastic film 320, a substrate suction member 330 that includes a porous member 334 including a substrate suction surface 334a for suctioning the substrate WF and a pressure reducing portion 334b communicating with a pressure reducing unit 31. The substrate suction member 330 is held to the elastic film 320.

    Abstract: There is disclosed a substrate processing apparatus which can align a center of a substrate with a central axis of a process stage with high accuracy to prevent a defective substrate from being produced. The substrate processing apparatus includes: an eccentricity detecting mechanism configured to obtain an amount of eccentricity and an eccentricity direction of a center of the substrate, held on the centering stage, from a central axis of the centering stage; and an aligner configured to align the center of the substrate with a central axis of a process stage. The aligner obtains, after the substrate is transferred from the centering stage to the process stage, an amount of eccentricity and an eccentricity direction of the center of the substrate from the central axis of the process stage by use of the eccentricity detecting mechanism; and confirms that the obtained amount of eccentricity of the center of the substrate from the central axis of the process stage is within a predetermined allowable range.
