基于不考虑硅通孔的N层叠芯片的一维热传输解析模型,提出了硅通孔的等效热模型,获得了考虑硅通孔的三维集成电路热传输解析模型,并采用Matlab软件验证分析了硅通孔对三维集成电路热管理的影响.分析结果表明,硅通孔能有效改善三维集成电路的散热,硅通孔的间距增大将使三维集成电路的温升变大.
Based on the one-dimensional analytical thermal model for N strata stacked chips without through-silicon via (TSV),the equivalent thermal model for TSV is presented in this paper.And then,the corresponding analytical thermal model with considering TSV is deriveed.Finally,Matlab software is used to verify and analyze the influence of TSV on the thermal management of 3D IC intergration.The analysis results indicate that the TSV can effectively improve the heat dissipation of 3D IC circuits,and the increase of TSVs's pitch can raise the temperature of the 3D IC circuit.
