Patent number: 8217512Abstract: A thermal interface device (100) includes a base member (102) and a pocket (104) which is filled with a thermally conductive material or medium such as diamond dust suspended in a solvent such as propylene glycol or a thermally conductive material such as thermally conductive rubber. The pocket (104) is hermitically sealed to the base member (102) in order to keep the thermally conductive material within the pocket. The filled pocket (104) forms a deformable “pillow” having a high thermal conductance. The deformable pocket (104) can contour to the shape of a device it is pressed against such as an electronic device undergoing testing.Type: GrantFiled: September 25, 2006Date of Patent: July 10, 2012Assignee: EADS North America, Inc.Inventors: Gary Carlson, Frank Landon, Jeffrey Chen, Mark Minot, Joseph Talbert

Patent number: 8193043Abstract: An exemplary semiconductor die package of the invention has a metal-oxide substrate disposed between a first surface of a semiconductor die and a heat-sinking component, with a conductive die clip or one or more electrical interconnect traces disposed between the metal-oxide substrate and the first surface of the semiconductor die. The heat-sinking component may comprise a heat sink, or an adaptor plate to which a heat sink may be coupled. The conductive die clip or electrical trace(s) provides electrical connection(s) to the first surface of the semiconductor die, while the metal-oxide substrate electrically insulates the die from the heat-sinking component, and provides a path of high thermal conductivity between the die and the heat-sinking component. The second surface of the semiconductor die may be left free to connect to a circuit board, or a leadframe or interconnect substrate may be attached to it.Type: GrantFiled: September 15, 2010Date of Patent: June 5, 2012Assignee: Fairchild Semiconductor CorporationInventors: Oseob Jeon, Chung-Lin Wu, Eddy Tjhia, Bigildis C.
