BY-PRODUCT REMOVAL APPARATUS, CLEANED LEACHED CUTTER, METHOD FOR REMOVING BY-PRODUCT MATERIAL, AND METHOD FOR DETERMINING EFFECTIVENESS OF REMOVING BY-PRODUCT MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a cleaned leached component having a polycrystalline structure, a method and apparatus for cleaning a leached component to form the cleaned leached component, and a method for determining the effectiveness of cleaning the leached component.;SOLUTION: A cleaned leached component includes at least one leached layer that has at least a portion of by-product materials removed from the inside. An apparatus and method for cleaning includes a tank, a cleaning fluid placed within the tank, and at least a portion of the leached layer immersed into the cleaning fluid. A method for determining the effectiveness of cleaning includes cleaning the leached component to form the cleaned leached component, measuring one or more capacitance values of the cleaned leached component, and repeating the cleaning and the measuring until achieving a stable lower limit capacitance value.;COPYRIGHT: (C)2013,JPO&INPIT
