    摘要: A structure formed on a semiconductor wafer is examined by obtaining a first diffraction signal measured using a metrology device. A second diffraction signal is generated using a machine learning system, where the machine learning system receives as an input one or more parameters that characterize a profile of the structure to generate the second diffraction signal. The first and second diffraction signals are compared. When the first and second diffraction signals match within a matching criterion, a feature of the structure is determined based on the one or more parameters or the profile used by the machine learning system to generate the second diffraction signal.

    摘要: A method is provided for predicting leakage current in a semiconductor die with a plurality of devices. A limited leakage macro is incorporated on the semiconductor die. The limited leakage macro is initially tested to measure a leakage current before testing devices outside the limited leakage macro. The measured leakage current is compared to a threshold value for the leakage current. If the leakage current exceeds the threshold value, probe testing is terminated. If, however, the leakage current does not exceed the threshold value, testing continues for devices outside of the limited leakage macro.

    摘要: Methods and arrangements to enhance photon emissions responsive to a signal within an integrated circuit (IC) for observability of signal states utilizing, e.g., picosecond imaging circuit analysis (PICA), are disclosed. Embodiments attach a beacon to the signal of interest and apply a voltage across the beacon to enhance photon emissions responsive to the signal of interest. The voltage is greater than the operable circuit voltage, Vd, the enhance photon emissions with respect to intensity and energy. Thus, the photon emissions are more distinguishable from noise. In many embodiments, the beacon includes a transistor and, in several embodiments, the beacon includes an enablement device to enable and disable photon emissions from the beacon. Further, a PICA detector may capture photon emissions from the beacon and process the photons to generate time traces.

    摘要: Disclosed is a novel method and apparatus for acquiring multiple capacitively sensed measurements from a circuit under test. Multiple digital sources are respectively connected to stimulate multiple respective first ends of multiple respective nets of interest. Respective second ends of the multiple respective nets of interest are capacitively sensed. The respective capacitively coupled signals are digitally sampled and shift correlated with respective expected digital signatures. If a high level of correlation is found for a given net, the net is electrically intact; otherwise, the net is characterized by either an open or some other fault that prevents it from meeting specification.

    摘要: A testing system evaluates one or more integrated circuit chips using RF communication. The system includes an interrogator unit with a radio communication range, and an IC chip adapted with RF circuitry positioned remotely from the interrogator unit, but within the radio communication range. The interrogator unit transmits a power signal to energize the IC chip during test procedures, and interrogating information for evaluating the operation of the IC chip. Test results are transmitted by the IC chip back to the interrogator unit for examination to determine whether the IC chip has a defect. In this manner, one or more IC chips can be evaluated simultaneously without physically contacting each individual chip.
