Abstract: There is provided a novel Cu bonding wire that achieves a favorable FAB shape and achieve a favorable bond reliability of the 2nd bonding part even in a rigorous high-temperature environment. The bonding wire for semiconductor devices includes a core material of Cu or Cu alloy, and a coating layer having a total concentration of Pd and Ni of atomic % or more formed on a surface of the core material. The bonding wire is characterized in that:



in a concentration profile in a depth direction of the wire obtained by performing measurement using Auger electron spectroscopy (AES) so that the number of measurement points in the depth direction is 50 or more for the coating layer,
a thickness of the coating layer is 10 nm or more and 130 nm or less,
an average value X is 0.2 or more and 35.0 or less where X is defined as an average value of a ratio of a Pd concentration CPd (atomic %) to an Ni concentration CNi (atomic %), CPd/CNi, for all measurement points in the coating layer,
the total number of measurement points in the coating layer whose absolute deviation from the average value X is or less is 50% or more relative to the total number of measurement points in the coating layer, and
the bonding wire satisfies at least one of following conditions (i) and (ii):
(i) a concentration of In relative to the entire wire is 1 ppm by mass or more and 100 ppm by mass or less; and
(ii) a concentration of Ag relative to the entire wire is 1 ppm by mass or more and 500 ppm by mass or less.

Abstract: A method for manufacturing raised contacts on the surface of an electronic component includes bonding one end of a wire to an area, such as a terminal, of the electronic component, and shaping the wire into a wire stem configuration (including straight, bent two-dimensionally, bent three-dimensionally). A coating, having one or more layers, is deposited on the wire stem to (i) impart resilient mechanical characteristics to the shaped wire stem and (ii) more securely attach ("anchor") the wire stem to the terminal. Gold is one of several materials described that may be selected for the wire stem. A variety of materials for the coating, and their mechanical properties, are described. The wire stems may be shaped as loops, for example originating and terminating on the same terminal of the electronic component, and overcoated with solder. The use of a barrier layer to prevent unwanted reactions between the wire stem and its environment (e.g., with a solder overcoat) is described. Bonding a second end of the wire to a sacrificial member, then removing the sacrificial member, is described. A plurality of wire stems may be formed on the surface of the electronic component, from different levels thereon, and may be severed so that their tips are coplanar with one another. Many wire stems can be mounted, for example in an array pattern, to one or to both sides of electronic components including semiconductor dies and wafers, plastic and ceramic semiconductor packages, and the like.

a thickness of the coating layer is 10 nm or more and 130 nm or less,
an average value X is 0.2 or more and 35.0 or less where X is defined as an average value of a ratio of a Pd concentration CPd (atomic%) to an Ni concentration CNi (atomic%), CPd/CNi, for all measurement points in the coating layer,
the total number of measurement points in the coating layer whose absolute deviation from the average value X is 0.3X or less is 50% or more relative to the total number of measurement points in the coating layer, and
the bonding wire satisfies at least one of following conditions (i) and (ii):

(i) a concentration of In relative to the entire wire is 1 ppm by mass or more and 100 ppm by mass or less; and
(ii) a concentration of Ag relative to the entire wire is 1 ppm by mass or more and 500 ppm by mass or less.
