  • Publication number: 20200095703
    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.

  • Publication number: 20190017517
    Abstract: A centrifugal blower includes a stator housing. The stator housing includes a radial contact surface which makes contact with a casing in a radial direction, a circumferential contact surface which makes contact with the casing in a circumferential direction, and an axial contact surface which makes contact with the casing in an axial direction. With such configuration, it is possible to reduce the vibration of the blower by increasing a contact area between the casing and the stator housing. Further, the stator housing includes a heat dissipating surface. As a result, it is possible to efficiently dissipate the heat, which is generated from the stator, from the heat dissipating surface of the stator housing to the gas existing within the wind tunnel.
