Method of manufacturing a polisher |
摘要 |
In a method of making a polishing element a photoresist film 2 is first deposited on a surface of metal stock 1. A photomask 3 is then used to selectively cover portions of the deposited photoresist film 2. Thereafter, portions of the photoresist film 2 which are not covered by the photomask 3 are removed in order to leave exposed patterned portions 5 of the metal stock surface. Gulf-shaped recesses 6 are then etched into the exposed portions of the metal stock surface. The formation of gulf-shaped recesses 6 results from the application of a etchant while the metal stock 1 and the etchant are in physical motion relative to one another. After etching, remaining portions of the photoresist film 2 are removed from the metal stock. A polishing element 10 comprising cutting teeth 11 having acute cutting action angles results.
