Problems solved by technology

[0004] However, there is a limit in cost reduction because a large amount of gold (Au) is contained in the gold (Au)-silver (Ag) alloy wire
In addition, copper wires and copper wires coated with palladium (Pd) cannot be used for LED packages because reflectivity, the most important function of LEDs, is deteriorated

Abstract

A bonding wire for semiconductor devices and a method of manufacturing the same are disclosed. The bonding wire for semiconductor devices according to the present invention includes at least one selected from the group consisting of zinc (Zn), tin (Sn), and nickel (Ni) at 5 ppm to 10 wt%, and the remainder including silver (Ag) and other inevitable impurities.

Description

technical field [0001] The present invention relates to a bonding wire, and more particularly, to a bonding wire for a semiconductor device and a light emitting diode (LED) package using the bonding wire, in which silver (Ag) is used as a main component. Background technique [0002] A bonding wire is a metal wire for electrically connecting an IC chip or an LED chip and a lead frame, and is generally composed of gold (Au). [0003] In order to reduce costs when manufacturing bonding wires, copper (Cu) wires or copper (Cu) wires with palladium (Pd) coated thereon have been tried for bonding wires due to the sudden increase in the price of gold (Au) worldwide recently. . Copper (Cu) wires are mass-produced by some manufacturers, but research on gold (Au)-based alloy wires is ongoing because the properties of copper (Cu) are not close to those of gold (Au). Research has been conducted on gold (Au)-silver (Ag) alloy wires as gold (Au)-based alloy wires. The gold (Au)-silver ...
