Abstract: In a method for manufacturing a reformed SiC wafer 41 (a surface treatment method for a SiC wafer) having its surface that is reformed by processing an untreated SiC wafer 40 before formation of an epitaxial layer 42, the method includes a surface reforming step as described below. That is, the untreated SiC wafer 40 includes BPDs as dislocations parallel to an inside of a (0001) face, and TEDs. Property of the surface of the untreated SiC wafer 40 is changed so as to have higher rate in which portions having BPDs on the surface of the untreated SiC wafer 40 propagate as TEDs at a time of forming the epitaxial layer 42.

Abstract: In a method for manufacturing an SiC wafer, a work-affected layer removal step of removing a work-affected layer generated in a surface and inside of an SiC wafer is performed, so that the SiC wafer from which the work-affected layer is at least partially removed is manufactured. In the work-affected layer removal step, the SiC wafer having undergone a polishing step is etched with an etching amount of 10 μm or less by being heated under Si vapor pressure so that the work-affected layer is removed. In the polishing step, an oxidizer is used to produce a reaction product in the SiC wafer while abrasive grains are used to remove the reaction product. In the SiC wafer having undergone the polishing step, an internal stress caused by the work-affected layer is present at a location inner than the work-affected layer, and an internal stress of the SiC wafer is reduced by removing the work-affected layer in the work-affected layer removal step.

Abstract: A carbonaceous material is fabricated by a mixture of carbon powder and a binder. 10% by weight or more and 60% by weight or less of metal powder to the fabricated carbonaceous material is mixed. The mixed carbonaceous material and metal powder are pressurized and formed. A brush base material is fabricated by burning of the pressurized and formed carbonaceous material and metal powder. The fabricated brush base material is impregnated with oil. An impregnation rate of the oil to the mixed carbonaceous material and metal powder may be 0.5% by weight or more, for example.
