  • Publication number: 20150279786
    Abstract: Provided is a semiconductor wafer on which various types of semiconductor chips are assigned, the semiconductor wafer enabling different types of semiconductor chips having the same chip size to be easily distinguished. An excluded region (7) is formed on an outer periphery of the semiconductor wafer, and a region inside the excluded region (7) is divided into different types of regions (A), (B), (C), and (D). The regions (A), (B), (C), and (D) are defined by boundaries (22), (23), and (24). Mark chips (1), (2), (3), and (4) are respectively arranged in the vicinity of the both ends of the boundaries (21), (22), (23), and (24).
