  • Patent number: 7557565
    Abstract: A handler for sorting semiconductor chips after they have been tested includes a loading unit for loading chips to be tested and an unloading unit for unloading chips that have been already tested. Chips arrive in trays at the loading unit, and a loading picker removes the chips from the tray.

  • Patent number: 7495463
    Abstract: A handler for handling semiconductor chips during a testing process includes a loading position at which packaged chips are loaded into a test tray, and an unloading position at which the packaged chips are unloaded from the test tray. The test tray follows a path through the handler from the loading position to the unloading position, and from the unloading position to the loading position. By separately performing the loading and unloading operations at these different positions within the handler, malfunctions in loading and unloading pickers that load and unload the chips may be reduced. Further, a malfunction in one picker performing one operation may be prevented from influencing operations of the other picker performing another operation. Additionally, collision between the loading picker and the unloading picker may be prevented.
