Types, sizes, and locations of crystal defects of an epitaxial layer of a semiconductor wafer containing silicon carbide are detected. Next, a predetermined device element structure is formed and based on location information of the crystal defects of the semiconductor wafer, semiconductor chips free of crystal defects and semiconductor chips containing only extended defects (Frank dislocations, carrot defects) are identified as conforming product candidates among individual semiconductor chips cut from the semiconductor wafer while semiconductor chips containing foreign particle defects and triangular defects are removed as non-conforming chips. Next, electrical characteristics of all the semiconductor chips that are conforming product candidates are checked. Next, based on a conforming product standard obtained in advance, a standard judgment is performed for all the semiconductor chips that are conforming product candidates, whereby semiconductor chips that are conforming products are identified.
