Modeling of Equivalent Thermal Conductivity of Power Delivery Network in 3D Packages
As increased integration density and power dissipation in 3-D structures,temperature constraints have aroused widespread concern in 3-D ICs.Consisting of good thermal conduction material,power delivery networks(PDN)in 3D packages have significant thermal removal capability.In previous work,the thermal capability and models of PDN in 3D packages are simply described.Here,we propose structurally based models to calculate the equivalent thermal conductivities of PDN.For different heat flows,two different calculation methods of equivalent thermal conductivities for the TSV structures are discussed.Combination of the equivalent thermal conductivity of PDN and the finite element method(FEM),a compact and accurate thermal analysis can be carried out.
