Non-destructive analysis of leakage points in Si-based power diodes.
In lock-in thermal analysis, it is desirable to increase the frequency to narrow down the hotspots; however, there is a problem that the sensitivity decreases. Therefore, it is important to shift the measurement conditions from the high-frequency side to the low-frequency side and identify the frequency at which the heating signal begins to be obtained. In this case, we will introduce an example where the heating location associated with leakage current was identified non-destructively in a cylindrical package. Thus, it is possible to identify heating locations even in samples with complex three-dimensional structures, which are difficult to analyze using the liquid crystal method.
