Abstract As semiconductor technology continues to advance to smaller dimensions and more complex circuit designs, it is becoming more challenging to locate the resistive short directly between two metal lines (signals) due to a metal bridge defect. Especially these two metal lines are very long and relevant to many functional modules. After studying the failed circuit model, we found there should be a tiny leakage between one of the bridged signals and one of common power signals (such as VDD and GND) on a failed IC compared with the reference one, if there is a metal bridge defect between these two bridged signals. The tiny leakage between one of the bridged signals and one of power signals is an indirect leakage that is a mapping of the direct resistive short between these two bridged signals. The metal bridge defect could be pinpointed with the tiny leakage between one of the bridged signals and one of power signals by Lock-in IR-OBIRCH. It is an easier and faster way to locate the metal bridge defects. In this paper, the basic and simple circuit model with a metal bridge defect will be presented and two cases will be studied to demonstrate how to localize a metal bridge defect by the tiny leakage between one of the bridged signals and one of power signals.

A novel, improved equivalent circuit model of double-sided linear induction motors (DLIMs) is proposed, which takes the skin effect and the nonzero leakage reactance of the secondary, longitudinal, and transverse end effects into consideration. Firstly, the traditional equivalent circuit with longitudinal and transverse end effects are briefly reviewed. Additionally, the correction coefficients for longitudinal and transverse end effects derived by one-dimensional analysis models are given. Secondly, correction factors for skin effect, which reflects the inhomogeneous air gap magnetic field vertically, and the secondary leakage reactance are derived by the quasi-two-dimensional analysis model. Then, the proposed equivalent circuit is presented, and the excitation reactance and secondary resistance are modified by the correction coefficients derived from the three analytical models. Finally, a three-dimensional (3D) finite element model is used to verify the proposed equivalent circuit model under varying air gap width and frequency, and the results are also compared with that of the traditional equivalent circuit models. The calculated thrust characteristics by the proposed equivalent circuit and 3D finite element model are experimentally validated under a constant voltage–frequency drive.
