摘要： A hard crystal substrate such as a GaN substrate or a SiC substrate is polished by using polishing oil slurry having abrading particles of artificial diamond clusters dispersed in a dispersant. The artificial diamond clusters include approximately spherical agglomerate particles with average particle size D50 of 20 nm or more and 50 nm or less, having primary particles with particle diameters of 2 nm or more and 10 nm or less. A rough polishing process is carried out first such that an average surface roughness of 0.5 nm or more and 1 nm or less is obtained, followed by a finishing process such that the average surface roughness of said surface becomes 0.2 nm or less.

摘要： A polishing system and a method are presented for uniformly polishing efficiently at a fast rate the surface of a tape-like metallic base material of several hundred meters in length. The polishing system is provided not only with devices for causing the base material to travel continuously and applying a specified tension in the base material but also with a first polishing device for randomly polishing the target surface and a second polishing device for carrying out a final polishing on the target surface in the direction of travel of the base material. Polishing marks are formed in the direction of travel on the target surface by the final polishing.

摘要： Polishing particles are made of artificial diamond produced by a shock method, having density of 3.0-3.35 g/cm3 and including secondary particles with average particle diameter of 30 nm-500 nm. Such polishing particles are produced by firstly obtaining a product containing artificial diamond by a shock method, then subjecting this product to an acid treatment by using one or more strong acids such as concentrated sulfuric acid, concentrated nitric acid and concentrated hydrochloric acid to thereby remove impurities from and wash the product, thereafter subjecting the product to a classification process to thereby separate artificial diamond of a first kind having secondary particles with particle diameters of 30 nm-500 nm and artificial diamond of a second kind having secondary particles with particle diameters in excess of 500 nm and selecting artificial diamond of a third kind having density of 3.0-3.35 g/cm3 out of the artificial diamond of the first kind. It is the artificial diamond of the third kind that is to be used as the diamond polishing particles.

摘要： Diamond clusters are used as a polishing material of free abrading particles, each being a combination of artificial diamond particles having primary particle diameters of 20 nm or less and impurities that are attached around these diamond particles. The density of non-diamond carbon contained in the impurities is in the range of 95% or more and 99% or less, and the density of chlorine contained in other than non-diamond carbon in the impurities is 0.5% or more and preferably 3.5% or less. The diameters of these diamond clusters are in the range of 30 nm or more and 500 nm or less, and their average diameter is in the range of 30 nm or more and 200 nm or less. Such polishing material is produced first by an explosion shock method to obtain diamond clusters and then removing the impurities such that density of non-diamond carbon contained in the impurities and density of chlorine contained in other than non-diamond carbon in the impurities become adjusted.

摘要： A device for cleaning the tip portion and the side surfaces of a probe has two or more different kinds of intermediate sheets affixed to a substrate in a side-by-side relationship with respect to each other. One of these intermediate sheets is an elastic sheet having an elastic property. Another intermediate sheet of a different kind is a plastic sheet which is less elastic. The tip portion of a probe is cleaned by a polishing layer affixed to the elastic sheet. The side surfaces of the probe are cleaned by a polishing layer affixed to the plastic sheet. A porous foamed sheet having openings on its surface and having air bubbles inside may be used as the elastic sheet. A polishing layer is formed on the surface of the foamed sheet, having a porous surface with openings corresponding to the openings on the foamed sheet. A spacer may be provided between the substrate and the plastic sheet for adjusting the heights of the polishing layers formed over the intermediate sheets.

摘要： A polishing apparatus, for polishing/cleaning a target object surface by using a polishing tape, has a spindle rotatably placed inside an opening formed in a base plate, a motor for rotating the spindle, a compression roller rotatably supported between a pair of side walls attached to the spindle, supply and take-up rollers supported rotatably by the side walls for advancing the polishing tape, and a motor for the take-up roller. The polishing tape is supplied from the supply roller and taken up by the take-up roller through the compression roller, while rotating around with the spindle. The compression roller has a smaller diameter at its center part than at its end parts for preventing the polishing tape from becoming twisted or wrinkled when the compression roller is rotated by the motion of the spindle while being pressed against a target object and being advanced from the supply roller to the take-up roller.

摘要： A circular polishing pad has grooves formed on the surface in a spiral pattern with its center point offset from the center of the pad. The spiral pattern is an Archimedean spiral pattern or a parabolic spiral pattern. A target object is polished by using such a polishing pad without oscillating the platen to which the polishing pad is pasted or the polishing head that holds the target object.
