    摘要: A method of purifying an alkaline solution includes dissolving metallic silicon and/or silicon compounds in the alkaline solution and non-ionizing metallic ions in the alkaline solution with reaction products generated when the metallic silicon and/or silicon compounds are dissolved therein. This purifying method is capable of remarkably decreasing metallic ions in the alkaline solution at a low-cost by an easy operation. A method of etching semiconductor wafers includes purifying an alkaline solution by non-ionizing metallic ions in the alkaline solution and etching the semiconductor wafers by using the purified alkaline solution. According to this etching method, the metallic contamination level due to the etching of the semiconductor wafers is greatly decreased, there being neither deterioration in the wafer quality nor deterioration in the characteristic of the semiconductor device.

    摘要: A method for handling wafers one at a time for processing without the necessity for transporting the wafers in a carrier such as a wafer cassette or basket. After a manufacturing step such as a polishing step, the wafers are carried to a loader assembly in a horizontal orientation under the influence of flowing liquid. The wafers are then individually erected into a vertical orientation by being first stopped by stopper pins which stand vertically on a wafer receiving plate of a suction arm including a suction nozzle which firmly holds the wafers while the arm is pivotally rotated until the wafer is positioned into a vertical orientation. The vertical orientation thus achieved allows the wafer to be gripped by a wafer gripping portion of a transportation robot including grooved gripping arms operated by a mechanism which limits the force applied to the wafer. Cleaning baths include an arrangement for supporting wafers in a near vertical orientation and nozzles which direct cleaning liquids in a direction tending to prevent floating of the wafers. A brush cleaning bath provides for simultaneous cleaning of both sides of the wafer with rotatory brushes during which the wafer is supported vertically and made to move circumferentially by rollers while periodic vertical motion between the wafer-supporting rollers and the brushes is achieved with a drive motor and ball screw. A drying bath using infrared light completes the cleaning procedure before the wafers are loaded into an unloader assembly into which wafer cassettes are set.

    摘要: A polishing apparatus for polishing an object to be polished at a high flatness includes at least one plate with at least one object to be polished secured at an underside thereof, a head section surrounding the plate with a predetermined gap therebetween, a pressure applying device for applying a pressing force to the top of the plate, and a holding device for holding the plate in the plane of the polishing movement of the object to be polished. The pressure applying device and the holding device are both disposed in an inner space of the head section, the latter being movable perpendicular to the plane of the polishing movement. The attaching position of the holding device on the outer surface of the plate is set substantially at the same height as or at a position lower than the attaching position of the holding device on the inner surface of the head section. The intersecting point of the imaginary lines through the fixing positions of the holding device on the head section and those corresponding to them on the plate substantially lies on or at a position lower than the polishing surface of the object to be polished.

    摘要: A method of purifying an alkaline solution is capable of extremely efficiently nonionizing metallic impurity ions in an alkaline solution at a low cost. A method of etching semiconductor wafers in turn is capable of etching semiconductor wafers using the purified alkaline solution without deteriorating the quality of the semiconductor wafers. A reducing agent having an oxidation potential lower than a reversible electrode potential of metallic ions existing in the alkaline solution is dissolved in the alkaline solution to thereby nonionize the metallic ions existing in the alkaline solution.
