    摘要: In an exemplary method of inspecting a stack chip package, a first chip is prepared. The first chip includes a through-silicon via, first pad electrodes connected to the through-silicon via and probe pad electrodes connected to the through-silicon via. A testing chip is prepared. The testing chip includes second pad electrodes that are arranged to correspond with the first pad electrodes. The testing chip is temporarily adhered to the first chip such that the second pad electrodes are electrically connected to the first pad electrode respectively, to form a stack structure wherein the probe pad electrodes are exposed to for testing. An electrical signal is applied to the exposed probe pad electrodes to test the through-silicon via included in the first chip.
