Electrochemical migration (ECM) pose a high reliability risk to semiconductor devices. In this study, an ECM caused electrical failure case detail was shared, relevant electrical failure & ECM mechanism was also analyzed. To verify the failure mechanism discussed in this paper, ECM process was simulated on the same chip substrate. Besides, for the first time, the effect of chloride ion concentration...
Ohmic contacts must be made in any semiconductor device or integrated circuits(IC). Contact failures usually are related to high resistance or open. However, sometimes the defective contact may be Schottky character instead of ohmic contact. In this paper, a case study on such a contact failure is discussed.
This paper proposed a novel medical image fusion algorithm based on nonsubsampled contourlet transform (NSCT). Firstly, CT image and MRI image are decomposed into high and low frequency subband by NSCT. For selection of fusion rules, the coefficients of low frequency subband are fused by local entropy, and fusion criterion for the coefficients of high frequency subband is regional energy. The performance...
Vehicle license plate recognition has complex characteristics due to diverse effects as the fog, rain, shadows, irregular illumination conditions, partial occlusion, variable distances, cars' velocity, scene's angle and others. License-plate location in sensor images plays an important role in vehicle identification for automated transport systems. For the extraction of positioning in license plate...
In recent years, image fusion has become the focus of image processing. For the fusion problems of the multifocus images with the same scence, this paper proposed a new fusion method based on nonsampled contourlet transform(NSCT). Firstly, source images are decomposed in different scales and directions by NSCT, thus the low frequency subband coefficients and the high frequency subband coefficients...
