    摘要: The invention provides a wafer polishing apparatus and a wafer manufacturing method which can improve uniformity in polishing wafer surfaces. A wafer holding head comprises a head body; a diaphragm stretched inside the head body; a carrier fixed to the diaphragm to be displaceable in the direction of a head axis while holding the wafer; a retainer ring disposed around the carrier in concentric relation and fixed to the diaphragm to be displaceable in the direction of the head axis; and a thin plate disposed so as to project from the head body along a surface of the diaphragm. With the provision of the thin plate, an excessive pressing force acting upon the retainer ring from the diaphragm is suppressed, and the wafer surface can be prevented from being excessively polished at an outer peripheral edge.

    摘要: An apparatus for dressing a wafer polishing pad, including a disk-shaped dresser, an arm, and a control unit. The disk-shaped dresser is configured to be pressed against the polishing pad which rotates in a circumferential direction. The dresser is configured to rotate in a same direction as the polishing pad rotates due to frictional force generated between the dresser and the polishing pad. The arm is configured to support the dresser rotatably and to press the dresser against the polishing pad. The control unit is configured to control the arm to position the dresser such that a peripheral edge portion of the dresser is positioned outside a peripheral edge portion of the polishing pad by a predetermined distance.

    摘要: A wafer loading/unloading device and a method for producing wafers in which positioning and mounting can be effected in a stable manner when attaching the wafer to the polishing head and which make it possible to receive or transfer the polished wafer in a stable manner. The wafer loading/unloading device includes a main body portion for supporting a wafer W, a swinging shaft supporting a swinging arm connected to the main body portion, and an arm ascending/descending mechanism supporting the swinging arm such that it can ascend and descend. The main body portion is equipped with a wafer support portion and an action force absorbing mechanism for absorbing vertical force acting on the wafer support portion, so that the impact when attaching or detaching the wafer to or from the polishing head is mitigated. Thus, damage to the wafer and the polishing head is prevented and the wafer is transferred in a stable manner.
