A test apparatus includes one handler connected to a tester and one test board
divided into two or more sites or two or more test boards. Since only the sites
on the test board (or test boards) need be duplicated, rather than the loading
lanes or sorters of the handler, the test apparatus can be conveniently compact.
Further, while testing semiconductor devices on one site or one test board, semiconductor
devices in another site or on another test board can be sorted according to the
test result. This enables the reduction or elimination of tester idle time to optimize
the efficiency of the test apparatus.
