摘要:A method for forming a stud bumped semiconductor die is disclosed. Themethod includes forming a ball at the tip of a coated wire passing through a hole in a
capillary, where the coated wire has a core and an oxidation-resistant coating. The formedball is pressed to the conductive region on the semiconductor die. The coated wire is cut,thereby leaving a conductive stud bump on the conductive region, where the conductivestud bump includes an inner conductive portion and an outer oxidation-resistant layer.
