Abstract
A carrier tray for use with a prober is arranged to allow the prober to measure or test not only semiconductor wafers but also semiconductor packages and accurately position each of different-shaped semiconductor packages. A carrier tray includes a lowermost tray and an uppermost tray interposing therebetween an intermediate tray. The lowermost and uppermost trays and are each of a circular shape having a diameter D. A diameter Dof the intermediate tray is smaller than the diameter D. The intermediate tray is centrally formed with a screw hole portion in which a locking spacer screw is screwed. A semiconductor package is to be placed in a package holding pocket. With the locking spacer screw, the intermediate is slidable in an X and Y directions, so that the X and Y coordinates of the semiconductor package are determined uniquely relative to the carrier tray.
