摘要:
A structure and method for cooling a three-dimensional integrated circuit (3DIC) are provided. A cooling element is configured for thermal connection to the 3DIC. The cooling element includes a plurality of individually controllable cooling modules disposed at a first plurality of locations relative to the 3DIC. Each of the cooling modules includes a cold pole and a heat sink. The cold pole is configured to absorb heat from the 3DIC. The heat sink is configured to dissipate the heat absorbed by the cold pole and is coupled to the cold pole via an N-type semiconductor element and via a P-type semiconductor element. A temperature sensing element includes a plurality of thermal monitoring elements disposed at a second plurality of locations relative to the 3DIC for measuring temperatures at the second plurality of locations. The measured temperatures control the plurality of cooling modules.
