    摘要: A device, such as a 3DIC stacked device includes a first device under test (DUT) connected to a first force pad by a first through substrate via (TSV) stack and connected to a first sense pad by a second TSV stack. The device further includes a second DUT stacked above the first DUT and connected to a second force pad and a second force pad by a second third TSV and connected to a second sense pad by a fourth TSV. Functional blocks on either the first or second blocks can be accessed for testing by way of the TSVs. In some applications the TSVs are vertically aligned to form TSV stacks.

    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.

    摘要: A plurality of sets of test conditions of a die in a stacked system is established, wherein the plurality of test conditions are functions of temperatures of the die, and wherein the stacked system comprises a plurality of stacked dies. A temperature of the die is measured. A respective set of test conditions of the die is found from the plurality of sets of test conditions, wherein the set of test conditions corresponds to the temperature. The die is at the temperature using the set of test conditions to generate test results.
