  • Patent number: 8847383
    Abstract: An integrated circuit package strip employs a stiffener layer that houses a passive electronic component to maintain mechanical properties when a thinner substrate is used. The use of either a retention wall or a stiffener allows for the manufacture of these integrated circuit package using strip, matrix, or array technology where a larger board with a plurality of integrated circuit packages is produced industrially and then cut to individual units.

  • Patent number: 8637391
    Abstract: A method of manufacturing a semiconductor chip is disclosed. A die having a plurality of die-pads is attached to a substrate in a semiconductor package which includes a plurality of substrate-pads. The method involves forming conductive column bumps of differing volumes extending from the die-pads; attaching each of the column bumps to a corresponding substrate-pad to form a subassembly; and reflowing the subassembly so that the column bumps form robust electrical and mechanical connections between the die pads and the substrate pads.

  • Publication number: 20120127689
    Abstract: The present disclosure relates to an improved integrated circuit package and method with a encapsulant retention structure located adjacent to a packaged integrated chip on a substrate. The structure allows for the placement and retention of a larger quantity of encapsulant to seep under the packaged integrated chip. The retention wall placed on the substrate alternatively serves as substrate stiffener able to maintain mechanical properties to be used with a more desirable thinner substrate. In one embodiment, the use of openings and recesses in a stiffener layer of an integrated circuit package houses a passive electronic component to maintain mechanical properties when a thinner substrate is used. The use of either a retention wall or a stiffener allows for the manufacture of these integrated circuit package using strip, matrix, or array technology where a larger board with a plurality of integrated circuit packages is produced industrially and then cut to individual units.

  • Patent number: 7432825
    Abstract: A radio frequency identification system includes an interrogator for generating and transmitting an interrogation signal to a transponder. One or more transponders of the system receive the interrogation signal and return a data signal which includes identification and/or body characteristic information in one of multiple formats. The interrogator receives the data signal, determines the format of the data signal, and decodes the data signal to obtain the identification and/or body characteristic information. The interrogator operates to decode data signals from transponders not capable of transmitting body characteristic information and transponders which are-capable of transmitting body characteristic information.

  • Patent number: 7015826
    Abstract: A passive transponder including an integrated sensor is disclosed. The transponder receives an interrogation signal from a scanner, and is operable to transmit identification information and body characteristic information to a scanner. The scanner is operable to receive the identification and body characteristic information and display and/or store the information. The sensor is integrated into the transponder. If temperature is to be sensed, the transponder determines the temperature of the host using the temperature dependent characteristics of the P-N junction of the integrated circuit.

  • Patent number: 6849940
    Abstract: An integrated circuit package includes a first or active substrate and a second or passive substrate. The active substrate includes at least one circuit that generates heat during circuit operation. The passive substrate does not include any heat-generating circuits, although the passive substrate may include passive, disabled or dormant circuitry. The two substrates are preferably fabricated of semiconductor material and have substantially equal coefficients of thermal expansion. The passive substrate is thermally coupled to the active substrate preferably using a thin layer of adhesive, such as an epoxy. The passive substrate serves to thermally conduct the heat generated by the circuits of the active substrate away from the active substrate. An internal metallic heat sink may be optionally thermally coupled to the passive substrate to further aid in the transfer of heat away from the active substrate.
