Patent number: 7067905Abstract: The present invention is directed toward methods and apparatuses for encapsulating a microelectronic die or another type of microelectronic device. One aspect of the present invention is directed toward packaging a microelectronic die that is attached to either a first surface or a second surface of a substrate. The die can be encapsulated by positioning the die in a cavity of a substrate and sealing the substrate to the substrate. The method can further include injecting an encapsulation compound into the cavity at a first end of the substrate to move along the first surface of the substrate. This portion of the compound defines a first flow of compound along the first surface that moves in a first direction from a first end of the substrate toward a second end of the substrate.Type: GrantFiled: August 8, 2002Date of Patent: June 27, 2006Assignee: Micron Technology, Inc.Inventor: Joseph M. Brand

Patent number: 6965515Abstract: A base station for a wireless communications system having a tower-mounted amplifier system with a low-noise amplifier transistor and a thermoelectric cooler that reduces the operating temperature of the low-noise amplifier transistor. The amplifier system has additional heat-generating components, such as filters, and additional electrical components mounted on a substrate to which the low-noise amplifier transistor is mounted. These heat-generating components are thermally isolated from the cold side of the thermoelectric cooler. As a result, the cooling capacity and electrical power requirement for the thermoelectric cooler is significantly reduced because only the low-noise amplifier transistor is cooled.Type: GrantFiled: August 21, 2003Date of Patent: November 15, 2005Assignee: Andrew CorporationInventors: James L. Alford, Mike Thomas

Patent number: RE42252Abstract: A multichip module comprises a multilayer substrate circuit having conductive patterns on its surface(s) to which microelectronic device(s) are attached. A part of the substrate is flexible and bifurcated. Two rigid members are attached lengthwise, one on either side of the substrate, and the free ends of the bifurcation are reflexed respectively about these members and bonded to them. Electrodes are located on the bifurcations so that they will be exposed outwardly and/or downwardly after reflexing. The module may further be provided with protective heat spreading covers. The electrodes and rigid members may be configured to engage a mating socket or they may be solderable to a printed circuit board.Type: GrantFiled: July 20, 2010Date of Patent: March 29, 2011Assignee: Microelectronics Assembly Technologies, Inc.Inventors: James E.
