    Abstract: A semiconductor device has a prefabricated multi-die leadframe with a base and integrated raised die paddle and a plurality of bodies extending from the base. A thermal interface layer is formed over a back surface of a semiconductor die or top surface of the raised die paddle. The semiconductor die is mounted over the raised die paddle between the bodies of the leadframe with the TIM disposed between the die and raised die paddle. An encapsulant is deposited over the leadframe and semiconductor die. Vias can be formed in the encapsulant. An interconnect structure is formed over the leadframe, semiconductor die, and encapsulant, including into the vias. The base is removed to separate the bodies from the raised die paddle.

  • Patent number: 8350368
    Abstract: A method of manufacturing a semiconductor device includes providing a substrate having a conductive bump formed over the substrate and a semiconductor die with an active surface oriented to the substrate. An encapsulant is deposited over the semiconductor die and the conductive bump, and the encapsulant is planarized to expose a back surface of the semiconductor die opposite the active surface while leaving the encapsulant covering the conductive bump. A channel is formed into the encapsulant to expose the conductive bump. The channel extends vertically from a surface of the encapsulant down through the encapsulant and into a portion of the conductive bump. The channel extends through the encapsulant horizontally along a length of the semiconductor die. A shielding layer is formed over the encapsulant and the back surface of the semiconductor die.

  • Patent number: 8311944
    Abstract: A transaction process system (10) provides for data transactions between parties. In a credit card transaction, the parties are the merchant (20), acquiring bank (24), card association (34), issuing bank (14), and cardholder (12). A transaction processing center (30) is positioned between the acquiring bank and the card association. The transaction processing center provides data processing channels for message-based processing (72) and filed-based processing (76). The file-based processing uses an incoming queue (80) and outgoing queue (84) to simplify the interface. The transaction processing center also provides for currency conversions and account reconciliation on a per transaction basis. The transaction processing center uses a scheduler (160) to efficiently manage the data processing resources.

  • Patent number: 8306629
    Abstract: Systems and methods are disclosed to control the temperature of an RF hyperthermia system with minimum overshoot and to improve safety by, among other things, detecting a defective temperature sensor. Temperature overshoot may be minimized by compensating for the short-term temperature difference between the area being treated and the applicator delivering the RF energy. The RF energy may heat the tissue and then the tissue may transfer heat to the applicator sensor. The system may also adapt to various applicator sizes and shapes by modifying control loop coefficients based on initial probe response.
