    Abstract: In an optical carrier injection method, a pulsed optical beam having pulse duration of 900 fs or lower is applied on a backside of a substrate of an integrated circuit (IC) wafer or chip, and is focused at a focal point in an active layer on a frontside of the substrate. Photons of the optical beam are absorbed at the focal point by nonlinear optical interaction(s) to inject carriers. The pulsed optical beam may be applied using a fiber laser in which the fiber is doped with Yb and/or Er. An output signal may be measured, comprising an electrical signal or a light output signal produced by the IC wafer or chip in response to the injected carriers. By repeating the applying, focusing, and measuring over a grid of focal points in the active layer, an image of the IC wafer or chip may be generated.

    Abstract: A method includes measuring a plurality of latchup release parameter values of a monitored circuit to generate data. Each latchup release parameter value of the plurality of latchup release parameter values is associated with the monitored circuit exiting a latchup state. The method also include predicting, based on the data and based on one or more characteristic values of a protection circuit coupled to the monitored circuit, whether the protection circuit is likely to prevent an occurrence of a latent failure within the monitored circuit in particular latchup conditions.

    Abstract: A system and method for calibration of a commercial semiconductor test system (tester). The system receives a synchronization signal from the tester and detects light emission from a device under test (DUT). The system then compares the 5 timing and characteristics of the light emission to the synchronization signal to obtain a delay timing and signal change caused by intermediate elements of the tester. The delay timing and signal change are used to calibrate the various channels of the tester. Also described are various designs for DUT's to obtained enhanced accuracy of the delay timing. Further, a system and method are described for reconstruction of a test to signal and study of the effects of intermediate elements of the tester on the shape of the test signal.

    Abstract: Methods, apparatus and data structures useful in correcting PICA image data are described. An exemplary method comprises acquiring optical image data of a target having identifiable optical-image features, acquiring PICA image data of the target having identifiable PICA-image features corresponding to the optical-image features, matching PICA-image features with corresponding optical-image features, and calculating from matched PICA-image features and optical-image features a set of coefficients defining relationships between observed positions of PICA-image features and optical-image features. Corrections are applied to the observed positions of detected photons based on the coefficients. The coefficients may provide a local correction using a bilinear relationship giving the transformation of a rectangle formed by four features of the PICA-image data to fit a corresponding rectangle in the optical-image data. Alternatively, the coefficients may provide a global mapping function defining transformation of any point of the PICA-image data to fit a corresponding point in the optical-image data.
