Title: Electrode material for semiconductor element
Inventor: ISHIKAWA TETSUO
IPC: H01L21/60
Filed: 1985-02-12
Abstract: PURPOSE:To increase the soldering yield by improving the solder wettability by composing a solder plating layer out of two layers of lead plating and of tin plating and making both platings dull-finish. CONSTITUTION:A solder plating layer is composed of two layers of Pb plating and Sn plating and a composition of the solder plating layer is determined by a ratio of thickness of both. Accordingly the composition can be controlled within 1% by controlling a flow of an electric current at arranging those layers on a metallic base by electroplating. As those are dull-finish plated layers, a solder wettability is good. If a layer consisting of nickel, cobalt, iron or chromium a melting point of which is higher than copper and a copper alloy is arranged when the metallic base is made of copper or a copper alloy, the copper functions as a barrier preventing diffusion into a semiconductor element through the solder at brazing or when this material is used for the semiconductor device and that prevents a decline of the functions as of a semiconductor.
