Abstract

a novel oblique pyramid equivalent heat dissipation model is proposed for theoretically analyzing heat dissipation capacity of power chips with embedded TTSVs. Extra carefully researching correction of oblique thermal resistance, additional lateral thermal resistance, and thermal resistance of TSV insulation sleeve, the accurate theoretical thermal resistance model was established. Setting the FEA simulating results based on COMSOL Multiphysics as benchmark, heat dissipation effects of variation of radius of TTSV (r), thickness of the power chip (H₀), and side length of the single cell (L₀) have been numerically investigated. The maximum temperature relative error of the proposed model with FEA simulated results is not more than 0.2 %, 1 %, and 0.5 % for variation of r, H₀, and L₀, respectively. The proposed model has been theoretically and numerically proven to be effective and accurate.

嵌入 TTSV 散热阵列的功率芯片的新型精确稳态热阻模型

提出了一种新颖的斜金字塔等效散热模型，用于理论分析嵌入 TTSV 的功率芯片的散热能力。通过对斜向热阻、附加侧向热阻和 TSV 绝缘套管热阻的修正进行细致研究，建立了精确的理论热阻模型。以基于 COMSOL Multiphysics 的有限元分析仿真结果为基准，数值研究了 TTSV 半径（r）、功率芯片厚度（H0）和单芯片边长（L0）的变化对散热的影响。对于 r、H0 和 L0 的变化，所提出模型与有限元分析模拟结果的最大温度相对误差分别不超过 0.2%、1% 和 0.5%。从理论和数值上证明了所提出模型的有效性和准确性。
