    Silicon carbide wafers have both C-face and Si-face orientations because of the way they are grown.

    Silicon carbide wafers(SiC) is a binary compound formed by silicon (Si) and carbon (C) in a 1:1 ratio, with its basic structural unit being the Si-C tetrahedron. Take an example: Si atoms have a larger diameter, equivalent to apples, while C atoms have a smaller diameter, equivalent to oranges. When an equal number of oranges […]
