International Classification:

H01L 23/52
H01L 23/48
H01L 23/40
H01L 23/485
H01L 23/498

US Classification:

257780, 257778, 257738, 257E23021, 257E23069

Abstract:

The present invention relates to a method for connecting an integrated circuit chip to a circuit substrate. The method includes the step of pre-applying adhesive directly to a bumped side of an integrated circuit chip. The method also includes the steps of removing portions of the adhesive from the tips of the solder bumps to expose a contact surface, and pressing the bumped side of the integrated circuit chip, which has previously been coated with adhesive, against the circuit substrate such that the bumps provide an electrical connection between the integrated circuit chip and the circuit substrate. The adhesive is removed from the tips of the solder bumps using a solvent assisted wiping action. The pre-applied adhesive on the chip forms a bond between the integrated circuit chip and the circuit substrate.

International Classification:

G06Q 40/00

US Classification:

705 35

Abstract:

Systems and methods for performing fraud detection. As an example, a system and method can be configured to contain a raw data repository for storing raw data related to financial transactions. A data store contains rules to indicate how many generations or to indicate a time period within which data items are to be stored in the raw data repository. Data items stored in the raw data repository are then accessed by a predictive model in order to perform fraud detection.

International Classification:

H05K 116
H05K 114
H05K 111

US Classification:

174260

Abstract:

The present invention is an ultra-thin circuit package with a thinned electronic device having a thickness of less than about 100. mu. m; a flexible circuit substrate; and an adhesive layer with a thickness of less than about 25. mu. m between the electronic device and the circuit substrate. The circuit package is less than about 275. mu. m thick. In another embodiment, the circuit packages may be stacked on one another and laminated together to create an extremely high-density three-dimensional electronic circuit package.

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

H01M 618

US Classification:

429307

Abstract:

An electrochemical cell containing a cathode comprising silver vanadium oxide and an anode comprising lithium is disclosed that includes an improved electrolyte composition having the solvents propylene carbonate and 1,2-dimethoxyethane, and an additional third solvent that reduces the solubility of the composition of the silver vanadium cathode material. Preferably, the third solvent is a dialkyl carbonate such as dimethyl carbonate, diethyl carbonate or ethylmethyl carbonate. The improved electrolyte composition reduces the build up of resistance in the cell during cell discharge, and may affect the cell's performance in implantable cardiac defibrillator applications. The cell of the present invention may include a hybrid cathode containing a mixture of silver vanadium oxide and carbon monofluoride (CF. sub. x).

Abstract:

Features are described for efficiently and accurately identifying a user of an electronic device with limited user interaction. The features include receiving a mobile device identifier from the mobile device. The features include transmitting the mobile device identifier to a service provider associated with the mobile device. The features include receiving information identifying the user from the service provider. The features include identifying a set of candidates associated with at least a portion of the information. The features include generating a metric for the candidates included in the set of candidates. An individual metric indicates a degree of relatedness between a value for the user for the at least one data field and a value for a candidate for the at least one data field. The features include identifying the user as a specific candidate included in the set of candidates based on the metric corresponding to a threshold.
