Abstract:
A semiconductor device transporting and handling apparatus for use with a constant temperature chamber having a test section, said semiconductor device transporting and handling apparatus comprising: transport means for transporting semiconductor devices; carrier head means having a pick and place head picking up and placing down the semiconductor devices for transporting the semiconductor devices from a pick up location to a place down location; and a control system controlling operation of the semiconductor device transporting and handling apparatus; wherein semiconductor devices to be tested are transported by said transport means into a constant temperature chamber where said semiconductor devices are picked up by the pick and place head and transferred from said transport means by said carrier head means onto said test section in said constant temperature chamber which applies a predetermined test to the semiconductor devices, and upon completion of the test, the tested semiconductor devices are picked up by the pick and place head and transferred by said carrier head means from said test section to a predetermined location, said control system comprising: jam detecting means for issuing a detection signal upon detecting any jam which occurs when the tested semiconductor devices fail to be picked up from said test section by said pick and place head of said carrier head means; and motion control means operative in response to the detection signal from said jam detecting means for temporally moving said carrier head means so as to cause said pick and place head to position at a position distant from said pick up location on said test section.
