Abstract:
A semiconductor device testing apparatus comprising:a test section;a tester part provided in the test section;a handler part comprising:a loader section,an unloader section,general-purpose trays,test trays,a loading handler,an unloading handler, anda transport unit transporting said test trays;wherein a general-purpose tray loaded with semiconductor devices to be tested is supplied in the loader section of the handler part where a plurality of the semiconductor devices to be tested are transferred from said general-purpose tray to a test tray by said loading handler, said test tray is transported by said transport unit into the test section where said semiconductor devices loaded on said test tray are brought into electrical contact with a tester head of said tester part disposed in said test section to test operation of the semiconductor devices, after completion of the test, said test tray with the tested semiconductor devices loaded thereon is transported by said transport unit from the test section to the unloader section of the handler part where the tested semiconductor devices on said test tray are transferred by said unloading handler from said test tray onto a general-purpose tray, and the general-purpose tray with the tested semiconductor devices loaded thereon is taken out of said semiconductor device testing apparatus; anda storage information memory unit including a storage memory and a controller for controlling the storage memory, wherein transference of the tested semiconductor devices by said unloading handler from the test tray onto a general-purpose tray in said unloader section is performed without being sorted, the controller of said storage information memory unit controls the storage memory so that storage information of respective tested semiconductor devices, which includes at least a number assigned to each semiconductor device, test results of each semiconductor device, and an identification number of a socket of the tester part used in testing the associated semiconductor device in said test section, is stored in said storage memory every time each tested semiconductor device is stored in a semiconductor device storage portion of one general-purpose tray,and the general-purpose tray including the tested semiconductor devices thus transferred thereto without being sorted, is taken out of the semiconductor device testing apparatus, so that the tested semiconductor devices can be subjected to at least one of further processes including re-testing and subclassifying of the tested semiconductor devices using said storage information.
