THERMOELECTRIC COOLER (TEC) FOR SPOT COOLING OF 2.5D/3D IC PACKAGES

摘要

While the use of 2.5D/3D packaging technology results in a compact IC package, it also raises challenges with respect to thermal management. Integrated component packages according to the present disclosure provide a thermal management solution for 2.5D/3D IC packages that include a high-power component integrated with multiple lower-power components. The thermal solution provided by the present disclosure includes a mix of passive cooling by traditional heatsink or cold plate and active cooling by thermoelectric cooling (TEC) elements. Certain methods according to the present disclosure include controlling a temperature during normal operation in an IC package that includes a plurality of lower-power components located adjacent to a high-power component in which the high-power component generates a greater amount of heat relative to each of the lower-power components during normal operation.
