Abstract:
A process for manufacturing a conductive wire suitable for use in semiconductor packages, comprising the steps of:preparing a core wire of an extensible metal other than gold, said core wire having a diameter ranging from 300 &mgr;m to 500 &mgr;m and an outer surface; plating a gold-containing outer layer having a thickness ranging from 2.5 &mgr;m to 25 &mgr;m onto said outer surface of said core wire so as to form a gold-plated core wire; and drawing said gold-plated core wire into said conductive wire having a diameter ranging from 1 &mgr;m to 50 &mgr;m such that said gold-containing outer layer has a thickness ranging from 0.0125 &mgr;m to 2.5 &mgr;m after said drawing step.
