  • Conductive compositions and processes for use in the manufacture of semiconductor devices
    Publication number: 20060231801
    Abstract: The present invention is directed to a thick film conductive composition comprising: (a) electrically conductive silver powder; (b) zinc-containing additive; (c) glass frit wherein said glass frit is lead-free; dispersed in (d) organic medium. The present invention is further directed to an electrode formed from the composition above wherein said composition has been fired to remove the organic vehicle and sinter said glass particles. Still further, the invention is directed to a method of manufacturing a semiconductor device from a structural element composed of a semiconductor having a p-n junction and an insulating film formed on a main surface of the semiconductor comprising the steps of (a) applying onto said insulating film the thick film composition detailed above; and (b) firing said semiconductor, insulating film and thick film composition to form an electrode.
