近年来，三维系统级封装技术逐渐成为人们的关注焦点，是下一代集成电路封装设计最有发展潜力的实现方案。然而，热管理是系统级封装技术需解决的关键问题。图1是典型的系统级封装结构，包含堆叠芯片、硅通孔、封装基板、热界面材料以及多层凸点结构。若对该结构的所有细节进行建模，将会消耗巨大的计算资源，导致分析效率非常低下。因此，本论文将封装中的硅通孔层以及凸点层等复杂结构进行等效处理，提取它们在水平和垂直方向上的等效热导率以及等效比热容、等效密度等参数。例如，在建模过程中，采用 COMSOL Multiphysics® 传热模块对硅通孔层的水平方向等效热导率进行提取，边界设置如图2所示 ... 詳細を見る
In this work, we investigate the resonant properties of finite-sized membrane-mass-type elastic metamaterial thin plates. We find that the effective bending stiffness of such metamaterial thin plates can be controlled independently by the out-of-plane rotational resonances, so as to vary ... 詳細を見る
Today, low noise is a mandatory feature for power transformers to comply with customer specifications and environmental regulations. Therefore, it is crucial to develop sound prediction tools with sufficient accuracy to avoid overkill margins in design and costly modifications after ... 詳細を見る
