    Abstract: A polishing apparatus (30) has a polishing surface (32), a top ring (36) for holding a wafer (W), motors (46, 56) to move the polishing surface (32) and the wafer (W) relative to each other at a relative speed, and a vertical movement mechanism (54) to press the wafer (W) against the polishing surface (32) under a pressing pressure. The polishing apparatus (30) also has a controller (44) to adjust a polishing condition in a non-Preston range in which a polishing rate is not proportional to a product of the pressing pressure and the relative speed. The polishing apparatus (30) can simultaneously achieve uniform supply of a chemical liquid to a surface of the wafer (W) and a uniform polishing rate within the surface of the wafer (W).

    Abstract: A method is provided for polishing a device wafer (14), which has projections and depressions formed on a surface thereof, with the use of an abrading plate (12). The method comprises polishing the device wafer (14) while supplying a surface active agent and/or while dressing a surface of the abrading plate (12). This method for polishing the device wafer (14) can always exhibit a self-stop function, without being restricted by the composition of the abrading plate (12), and without being restricted by the type of the substrate.

    Abstract: A spindle motor which is designed to rotate with minimal vibrations and hence is suitable of a hard disk driver. The spindle motor employs hydrodynamic bearings as radial and thrust bearings. A support shaft is formed in a cylindrical configuration with a center hole, and a rotor has a columnar portion which is inserted into the center hole in the support shaft. A thrust bearing collar is attached to the lower end of the rotor, and a thrust bearing member is secured to a base in opposing relation to the thrust bearing collar. A group of stator coils and a radial bearing member are disposed on either the inner peripheral surface of the center hole in the support shaft or the outer peripheral surface of the support shaft, and a group of rotor magnets and a radial bearing sleeve are disposed on either the outer peripheral surface of the columnar portion or the inner peripheral surface of the rotor in opposing relation to the stator coil group and the radial bearing member.

    Abstract: ABRADING PLATE AND POLISHING METHOD USING THE SAME The present invention provides an abrading plate having self-stopping capability such that when an object, such as a semiconductor wafer having a device structure that includes raised regions and depressed regions fabricated on the surface, is being polished, the raised regions are removed and polishing stops automatically. A method of using the abrading plate is also provided. The present invention relates to an abrading plate that produces a flat and mirror polished surface on an object with an abrading plate comprised by abrasive particles having a chemical purity of not less than 90 % and a particle size of not more than two micrometers; a binder material; and a given volume of porosity, wherein a ratio of the abrasive particles and the binder material is not less than 1:0.5 by volume, and proportions of abrasive particles, a binder material and porosity are, respectively, not less than 10 %, not more than 60 % and 10-40 by volume. The method is provided for polishing an object having a device structure that includes raised regions and depressed regions fabricated on the surface according to the steps of polishing the surface for a given duration with a liquid not containing abrasive particles so as to eliminate the raised regions to obtain a flat surface, and performing additional surface removal by supplying abrasive particles to the polishing interface to remove surface material uniformly from the entire surface.
