摘要： A polishing head including, below a polishing head body, a rubber film held by a disk-shaped mid plate and an annular guide ring disposed around the rubber film holding the back surface of the workpiece on a lower face portion of the rubber film. The polishing head also includes a base member that is coupled to a polishing head body through an elastic film and holds the guide ring and the mid plate such that the lower surface of the guide ring does not contact the polishing pad during polishing. The polishing head and polishing apparatus, are operable in both of the rough polishing process and final polishing process, that can stably achieve predetermined high flatness and high polishing stock removal uniformity in polishing of a workpiece and can obtain a workpiece with fewer fine particles having a diameter of 45 nm or more.

摘要： There is disclosed a general-purpose APD measurement apparatus capable of changing a measurement condition, such as the number of channels or a resolution bandwidth (RBW) in compliance with a standard for the subject of measurement, measuring various subjects of measurement, and correcting measurement equipment, thereby enabling a higher accuracy of measurement. The resolution bandwidth (RBW) or the number of channels when measurement is performed can be flexibly changed by controlling the cycle of a clock signal whose data are sampled by A/D conversion means 110, frequency selection means 130, and an APD unit 300. The frequency selection means 130 includes FFT type processing means 131 and filter bank type processing means 132 arranged in parallel. The output of FFT type processing means 131 is corrected based on the output of the filter bank type processing means 132 with a high accuracy of measurement. Accordingly, a higher accuracy of measurement is made possible.

摘要： In the polishing system of the present invention, a adhering unit adheres a wafer on a carrying plate using liquid. A polishing unit polishes the wafer using a polishing plate. A feeding unit conveys the carrying plate from the adhering unit to the polishing unit. A dismounting unit removes the wafer from the carrying plate. A first discharging unit conveys the carrying plate from the polishing unit to the dismounting unit. A cleaning unit cleans the vacant carrying plate. A second discharging unit conveys the carrying plate from the dismounting unit to the cleaning unit. A third discharging unit conveys the carrying plate from the cleaning unit to the adhering unit. The units are formed into a loop lines so that the carrying plate is circulated in the loop line and the wafers are polished therein.
