  • Patent number: 8531025
    Abstract: A semiconductor module structure and a method of forming the semiconductor module structure are disclosed. The structure incorporates a die mounted on a substrate and covered by a lid. A thermal compound is disposed within a thermal gap between the die and the lid. A barrier around the periphery of the die extends between the lid and the substrate, contains the thermal compound, and flexes in response to expansion and contraction of both the substrate and the lid during cycling of the semiconductor module. More particularly, either the barrier is formed of a flexible material or has a flexible connection to the substrate and/or to the lid. The barrier effectively contains the thermal compound between the die and the lid and, thereby, provides acceptable and controlled coverage of the thermal compound over the die for heat removal.

  • Patent number: 8519409
    Abstract: The present disclosure relates to structures of LED components that integrate thermoelectric devices with LEDs on LED emitter substrates for cooling the LEDs. The present disclosure also related to methods for integrating LED dies with thermoelectric elements. The LED component includes an LED emitter substrate with a cavity in a downward facing surface of the LED emitter substrate and thermal vias that extend from a bottom of the cavity to an area close to an upward facing surface of the LED emitter substrate. The device also includes thermoelectric elements disposed in the cavity where the thermoelectric elements connect with their corresponding thermal vias. The device further includes a thermoelectric substrate in the cavity to electrically connect to the thermoelectric elements. The device further includes an LED die on the upward facing surface of the LED emitter substrate such that the LED die is opposite the cavity.
