Abstract: PURPOSE:To prevent the short circuit of a bump electrode and an irregular shape, and to grow a bump layer in an excellent shape by previously removing a foundation layer except a bump electrode section and conforming the thickness of the foundation layer to a chemical etching rate. CONSTITUTION:A metallic thin-layer as a foundation layer 20 is applied onto an element substrate 10, and the thin-layer except a section to which a bump electrode 31 is formed is removed through chemical etching treatment. The thickness of a thin-film to which the composite foundation layer 20 is shaped is selected so as to acquire the relationship of the same magnitude in response to the relation-ship of the magnitude of chemical etching rates to each layer in a photo-etching process. A metallic layer 30 for the bump electrode is grown selectively onto the left layer 20. Consequently, even when the etching rates of each layer in the composite metallic thin-film as the foundation layer differ, the shapes of the end sections of all layers are arranged and all layers can be etched by one process. Accordingly, the short-circuit of the electrode is removed, and the electrode can be grown in an excellent shape.
