  • Patent number: 7779554
    Abstract: The present invention provides a strip-like holding gripper which holds a semiconductor wafer when measuring a shape of the semiconductor wafer, wherein a side where the semiconductor wafer is held has a round shape, a groove which holds an edge of the semiconductor wafer along a side surface of the round shape portion is provided on the side surface, and the groove comes into contact with the edge of the semiconductor wafer from a periphery of the wafer to hold the semiconductor wafer. As a result, it is possible to provide the gripper, which can stably hold the wafer in a fixed state even if the gripper is inclined when holding the wafer, a holding method, and a shape measuring apparatus.
