Claim:
1. A system, comprising: a three dimensional integrated circuit (3D IC); a first thermoelectric cooler comprising a first plurality of semiconductor pellets disposed between a first cooling ceramic plate and a first warming ceramic plate and electrically connected such that the application of voltage across the first plurality of semiconductor pellets results in cooling the first cooling ceramic plate and warming the first warming ceramic plate, said first thermoelectric cooler coupled at the first cooling plate to a first side of the 3D IC by a first plurality of conductive pillars; a second thermoelectric cooler comprising a second plurality of semiconductor pellets disposed between a second cooling ceramic plate and a second warming ceramic plate and electrically connected such that the application of voltage across the second plurality of semiconductor pellets results in cooling the second cooling ceramic plate and warming the second warming ceramic plate, said second thermoelectric cooler coupled at the second cooling plate to a second side of the 3D IC by a second plurality of conductive pillars, wherein said second side is opposite said first side; a controller which controls the first thermoelectric cooler and the second thermoelectric cooler; and a temperature monitor positioned to sense a temperature of the 3D IC, the temperature monitor coupled to the controller.
