Abstract: A double-side polishing method of polishing both surfaces of a wafer by holding the wafer with a carrier including a holding hole configured to hold the wafer and a ring-shaped resin insert disposed along an internal circumference of the holding hole, the resin insert having an inner circumferential surface configured to contact a peripheral portion of the wafer, interposing the carrier between upper and lower turn tables to which polishing pads are attached, polishing both the surfaces of the wafer while maintaining planarity of the inner circumferential surface at or below 100 ?m and verticalness of the inner circumferential surface at or below 5°. The method can inhibit the degradation of the flatness of the polished wafer, such as particularly an outer circumferential sag, due to variation in shape of the inner circumferential surface of the resin insert of a carrier.

Abstract: A spreading tool and an associated method are provided to permit members that are biased toward one another to be separated in an efficient and a controlled manner. One example of a spreading tool includes a handle portion and a spreader portion coupled to the handle portion and defining a longitudinal axis. The spreader portion includes a cam profile defining a cam-lobe center line. The cam profile may also define a width perpendicular to the cam-lobe center line and a length parallel to the cam-lobe center line. In use, the spreader portion may be inserted between the two members such that the width of the cam portion separates the two members. The handle portion may then be rotated about the longitudinal axis of the spreader portion until the two members are separated by a distance greater than the width of the elongate cross-sectional cam profile.
