Abstract: A carbonaceous material is fabricated by kneading of carbon powder and a binder. A particle diameter of the carbonaceous material is adjusted after the fabricated carbonaceous material is granulated. A brush material is fabricated by mixing of the carbonaceous material of which the particle diameter is adjusted and metal powder. A brush is completed by forming and thermal processing of the fabricated brush material. In this case, the particle diameter of the carbonaceous material is adjusted in a constant range before the carbonaceous material and the metal powder are mixed such that an average particle diameter of the carbonaceous material in the brush is not less than 300 μm and not more than 2000 μm. Alternatively, a ratio of the volume of the carbonaceous material having the particle diameter of not less than 300 μm to the volume of the brush is adjusted to not less than 50%.

Abstract: To provide a technique capable of improving performance and reliability of a semiconductor device. An n−-type epitaxial layer (12) is formed on an n-type semiconductor substrate (11), and a p+-type body region (14), n+-type current spreading regions (16, 17), and a trench. TR are formed in the n−-type epitaxial layer (12). A bottom surface B1 of the trench TR is located in the p+-type body region (14), a side surface S1 of the trench TR is in contact with the n+-type current spreading region (17), and a side surface S2 of the trench TR is in contact with the n+-type current spreading region (16). Here, a ratio of silicon is higher than a ratio of carbon in an upper surface T1 of the n−-type epitaxial layer (12), and the bottom surface B1, the side surface S1, and the side surface 32 of the trench. Furthermore, an angle θ1 at which the upper surface T1 of the n−-type epitaxial layer (12) is inclined with respect to the side surface S1 is smaller than an angle θ2 at which the upper surface T1 of the n−-type epitaxial layer (12) is inclined with respect to the side surface S2.
