Abstract :
The high efficient thermal structures are designed to resolve the heat problems in 3D ICs. The three-layers-stacked chips with the area of 10×10mm2 and the thickness of 50μm are analyzed using the finite element method simulation tool. The heat spreaders, thermal vias, and heat paths are applied to the reference stacked chips for the thermal management. The suggested thermal structure shows the results of the temperature drop of the hotspots up to 8.4°C and the reduction of the temperature gradient by 20 to 30%.
