  • Patent number: 11955406
    Abstract: An IC die includes a temperature control element suitable for three-dimensional IC package with enhanced thermal control and management. The temperature control element may assist temperature control of the IC die when in operation. In one example, the temperature control element may have a plurality of thermal dissipating features disposed on a first surface of the IC die to efficiently control and dissipate the thermal energy from the IC die when in operation. A second surface opposite to the first surface of the IC die may include a plurality of devices, such as semiconductors transistors, devices, electrical components, circuits, or the like, that may generate thermal energy when in operation.
