  • Patent number: 8258010
    Abstract: A plurality of semiconductor die is mounted to a carrier separated by a peripheral region. An insulating material is deposited in the peripheral region. A first opening is formed in the insulating material of the peripheral region to a first depth. A second opening is formed in the insulating material of the peripheral region centered over the first opening to a second depth less than the first depth. The first and second openings constitute a composite through organic via (TOV) having a first width in a vertical region of the first opening and a second width in a vertical region of the second opening. The second width is different than the first width. A conductive material is deposited in the composite TOV to form a conductive TOV.

  • Patent number: 8216930
    Abstract: A flip chip interconnect has a tapering interconnect structure, and the area of contact of the interconnect structure with the site on the substrate metallization is less than the area of contact of the interconnect structure with the die pad. A solder mask has an opening over the interconnect site, and the solder mask makes contact with the interconnect structure, or is in close proximity to the interconnect structure, at the margin of the opening. The flip chip interconnect is provided with an underfill. During the underfill process, the contact (or near proximity) of the solder mask with the interconnect structure interferes with flow of the underfill material toward the substrate adjacent the site, resulting in formation of a void left unfilled by the underfill, adjacent the contact of the interconnect structure with the site on the substrate metallization. The void can help provide relief from strain induced by changes in temperature of the system.

  • Patent number: 8204824
    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 and an account reconciliation processor (200) to identify discrepancies and initiate corrective action.

  • Patent number: 8198186
    Abstract: A semiconductor device has a semiconductor die with die bump pads and substrate with trace lines having integrated bump pads. A solder mask patch is formed interstitially between the die bump pads or integrated bump pads. The solder mask patch contains non-wettable material. Conductive bump material is deposited over the integrated bump pads or die bump pads. The semiconductor die is mounted over the substrate so that the conductive bump material is disposed between the die bump pads and integrated bump pads. The bump material is reflowed without a solder mask around the integrated bump pads to form an interconnect between the semiconductor die and substrate. The solder mask patch confines the conductive bump material within a footprint of the die bump pads or integrated bump pads during reflow. The interconnect can have a non-fusible base and fusible cap.
