Abstract:
A method for manufacturing a semiconductor device, comprising steps of:forming first conductive pads in a region above and surrounding a semiconductor circuit element made on a semiconductor substrateforming a first protective insulating layer covering said first conductive pads;forming first openings in said first protective insulating layer and on said first conductive pads respectively;forming a resist having windows in the form of elongate groove extending from said first openings respectively to an inner region surrounded by said first openings;forming within said each of said windows a conductive bulk layer as a lead wire connected at one end thereof to each of said first conductive pads through each of said first openings;forming a metallic layer of a hard metal on each of said conductive bulk layer, said hard metal being harder than said conductive bulk layer;removing said resist;forming a second protective insulating layer for covering said first protective insulating layer and said lead wire; andforming second openings in said second protective insulating layer, for exposing the top surface of the other end of said lead wire as a second conductive pad.
