Abstract: According to a method herein, a multi-level inductor is created around a through-silicon-via (TSV) in a semiconductor substrate. A voltage induced in the multi-level inductor by current flowing in the TSV is sensed, using a computerized device. The voltage is compared to a reference voltage, using the computerized device. An electrical signature of the TSV is determined based on the comparing the voltage to the reference voltage, using the computerized device.

Abstract: System and method using low voltage current measurements to measure voltage network currents in an integrated circuit (IC). In one aspect, a low voltage current leakage test is applied voltage networks for the IC or microchip via one or more IC chip connectors. One or multiple specifications are developed based on chip's circuit delay wherein a chip is aborted or sorted into a lesser reliability sort depending whether the chip fails specification. Alternately, a low voltage current leakage test begins an integrated circuit test flow. Then there is run a high voltage stress, and a second low voltage current leakage test is thereafter added. Then, there is compared the second low voltage test to the first low V test, and if the measured current is less on second test, this is indicative of a defect present which may result in either a scrap or downgrade reliability of chip.

Abstract: A method of substantially reducing charge build-up in a SOI device is provided. The method includes depositing a dielectric material on a surface of a semiconductor structure which includes at least silicon-on-insulator (SOI) devices therein. Next, a first conductive material is deposited on the dielectric material and then holes are drilled through the conductive material and the dielectric insulating material. Each hole is filled with a second conductive material, and thereafter selective portions of the first conductive material are removed to form contact pads for further probing. The method is especially useful in focused ion beam (FIB) drilling.

Abstract: A temperature control fixture for an integrated circuit under test which provides for heating or cooling of the back side of the integrated circuit while it is being tested by contacts and electrical leads applied to the opposite lead side thereof. A test housing defines a sealed test chamber within which a test mounting is provided for mounting the integrated circuit under test. The test mounting is connected to a plurality of test lines for conducting test signals between the lead side of the integrated circuit and a test instrument external to the test apparatus. The integrated circuit is mounted on the test mounting to expose the back side thereof to a flow of a heat transfer medium in the sealed test chamber to provide for cooling or heating thereof. An observation window in the test housing enables observation of the back side of device during testing.
