  • Publication number: 20150362546
    Abstract: The present disclosure provides a probe apparatus that is capable of suppressing generation of a transfer error by adsorbing and holding a semiconductor wafer even in a case where the semiconductor wafer has been warped. The probe apparatus includes a measuring section and a loader section, that is, a transfer unit. The loader section is provided with a wafer cassette placed on a load port, a wafer transfer mechanism having a wafer transfer arm, and a gas ejection mechanism having a gas ejection nozzle. When the wafer transfer arm adsorbs and holds a warped semiconductor wafer in the wafer cassette, the gas ejection nozzle ejects a gas from a substantially central portion on the upper side of the semiconductor wafer toward the lower side, thereby reducing warpage of the semiconductor wafer.

  • Patent number: 7108471
    Abstract: A transporting tool of this invention transports a cracked wafer between an unload table and a test position through fork, having a vacuum suction mechanism, and a main chuck. The transporting tool of this invention has a first groove formed in a first surface of the transporting tool, a first through hole which is formed to correspond to a first opening of the fork and is open to the first groove, a second groove formed in a second surface to correspond to an attracting groove of the main chuck, and a second through hole which allows the first groove and second groove to communicate with each other.
