  • Publication number: 20250054816
    Abstract: Methods for fabricating diode wafers and wafers to be processed process raw wafers sliced from an ingot and determines whether the raw wafers meet a fabrication specification. When the determined result is yes, the raw wafer is used as a high-grade raw wafer. When the determined result is no, the raw wafers are used as low-grade raw wafers. Next, the method calculates the ratio of the number of low-grade raw wafers with problems related to crystal oriented pits to the number of all low-grade raw wafers and determines whether the ratio is greater than a preset value. When the ratio is not greater than the preset value, the partial structure of each low-grade raw wafer is removed and the surface of each low-grade raw wafer is smoothed. Finally, diode structures are formed in the smoothed low-grade raw wafers to obtain diode wafers.
