  • Reduction of warpage of multilayered substrate or package
    Patent number: 9672323
    Abstract: A method that minimizes adjustment of a wiring layer in reducing a warpage of a multilayered substrate and enables location of a part of a wiring layer that needs correction in order to reduce the warpage. The difference in average coefficient of thermal expansion, ??, varies in a substrate. The method focuses in on the difference in ?? with a great length scale (low frequency) having a relatively significant effect on the warpage compared to the difference in ?? with a smaller length scale (high frequency) and corrects only the difference in ?? with a greater length scale. The distribution of the difference in ?? in a plane of substrate is determined. Then digital filtering is performed to extract only the difference in ?? with a low frequency and the difference in ?? between before and after correction, thereby revealing a part that requires correction.
