Abstract

A kind of method for testing semiconductor device is disclosed in the present invention. In the testing method, the object to be tested, which is placed in the carrying cartridge, is moved to the delivering rail having dual temporary storage regions to maintain the state of temporarily placing the object to be tested in the second temporary-storage region and making the first temporary storage region empty. Then, the object to be tested, which is stored temporarily on the delivering rail, is moved to the testing component having dual test region so as to maintain the test region in the state of always having object to be tested in coordination with disposing and moving member, so that the testing head of the testing member is capable of conducting test onto the object to be tested in a continuous way. Then the object to be tested, which is completed with the test, is transmitted to the carrying cartridge via a delivering rail; and the object to be tested is disposed on the delivering rail periodically. Thus, through the use of dual temporary storage regions, dual testing regions, and the design of specific delivery mode for distributing the object to be tested, the testing method can decrease the idle and waiting time of the testing member so as to further effectively increase its testing efficiency.
