发明名称 Rotational positioner and methods for semiconductor wafer test systems
摘要 A semiconductor wafer prober is configured to rotate a semiconductor wafer into relative alignment with a wafer-interface probe adapted to simultaneously probe a number of integrated circuits within a sector of the semiconductor wafer. The wafer can include integrated circuits having different orientations, such that all of the integrated circuits within a given sector being tested have the same orientation. For example, a semiconductor wafer can include two semicircular sectors, with the integrated circuits on either sector having a common orientation rotated 180 degrees from a common orientation of the integrated circuits of the other sector. A wafer-interface probe, or probe card, adapted to test the entire semicircular sector during a single touch down is able to test the entire wafer with one rotational translation between testing.
