    摘要: A three dimensional (3D) integrated circuit (IC) testing apparatus includes a plurality of connection devices. When a device under test (DUT) such as an interposer or a 3D IC formed by a plurality of 3D dies operates in a testing mode, the 3D IC testing apparatus is coupled to the DUT via a variety of interface channels such as probes. The connection devices and a variety of through silicon vias (TSVs) in the DUT form a TSV chain so that an electrical characteristic test of the variety of TSVs can be tested all at once.

    摘要: A method includes testing a first device and a second device identical to each other and comprising integrated circuits. The testing of the first device is performed according to a first test sequence of the first device, wherein the first test sequence includes a plurality of ordered test items, and wherein the first test sequence includes a test item. A test priority of the test item is calculated based on a frequency of fails of the test item in the testing of a plurality of devices having an identical structure as the first device. The first test sequence is then adjusted to generate a second test sequence in response to the test priority of the test item, wherein the second test sequence is different from the first test sequence. The second device is tested according to the second test sequence.
