Abstract: A ball-bond arrangement comprising a bond pad of a semiconductor device and a wire ball-bonded to the bond pad, wherein the wire extending from the bonded ball has a diameter of 15 to 50 ?m, and comprises a silver-based wire core with a surface, the wire core having a coating layer superimposed on its surface, wherein the coating layer is a double-layer comprised of a 1 to 40 nm thick inner layer of palladium or nickel and an adjacent 20 to 500 nm thick outer layer of gold, and wherein the surface of the bonded ball has a gold coverage of 70 to 100%.

Abstract: A wire comprising a wire core with a surface, the wire core having a coating layer superimposed on its surface, wherein the wire core itself is a silver-based wire core, wherein the coating layer is a double-layer comprised of a 1 to 100 nm thick inner layer of nickel or palladium and an adjacent 1 to 250 nm thick outer layer of gold, characterized in that the wire exhibits a total carbon content of ?40 wt.-ppm.

Abstract: To achieve tin deposits being largely free of pressure induced whiskers, a method of depositing a tin layer on a metal substrate is devised, wherein said method comprises: (a) providing said metal substrate; (b) depositing a nickel/phosphorous alloy underlayer on at least one surface of said metal substrate; and (c) depositing said tin layer on said nickel/phosphorous alloy underlayer by depositing said tin layer comprising using a pulse plating method.

Abstract: An electronic advertisement method and system for an Internet browser with a book-like page-based flipping interface. Full pages of electronic advertisements presented on the computer screen are possible without obstructing the viewing and reading of other contents. This benefits both the viewer as well as the advertiser. An advertisement matching/delivery system provides a novel method of inserting advertisements into content as well as a novel method for revenue sharing among the parties involved.
