Abstract:
1. A carrier tray for a semiconductor package, which is used in a test of the semiconductor package by a prober for testing a semiconductor wafer, the carrier tray comprising: a first tray provided with a plurality of rectangular holding parts arranged in a matrix, each of which has a depth smaller than thickness of the semiconductor package and is configured to hold the semiconductor package; and a second tray provided with a plurality of first windows arranged in correspondence with the plurality of rectangular holding parts, each first window being of a rectangular shape to surround each semiconductor package, and the second tray being placed in contact with the first tray; wherein the first and second trays are slidable relative to each other, one of the first and second trays is of an outer diameter equals to an outer diameter of the semiconductor wafer to be handled by the prober and an outer edge of the other tray stays within a range corresponding to an outer edge of one of the first and second trays during sliding, and wherein the second tray includes: a first-direction tray movable in a first direction, and a second-direction tray movable in a second direction, the first-direction tray and the second-direction tray being placed in contact with each other to be slidable relative to each other.
