Abstract: A conventional semiconductor device has a problem that reduction of a connection resistance value between wiring layers is difficult because of an oxide film formed between the wiring layers. In a semiconductor device of this invention, a first metal layer is embeded in opening regions which connect a first wiring layer and a second wiring layer and an opening is formed in a spin coated resin film formed on the first metal layer. In the opening, a Cr layer forming a plating metal layer and a Cu plated layer are connected to each other. With this structure, the spaces among crystal grains in portions in the Cr layer on the first metal layer are wide, which causes the portions to be coarse. In the coarse portions in the Cr layer, an alloy layer formed of the second metal layer and the Cu plated layer is formed, and thus, the connection resistance value is reduced.

Abstract: A conventional semiconductor device has a problem that reduction of a resistance value above a pad electrode is difficult because of an oxide film formed on a surface of the pad electrode. In a semiconductor device of this invention, an oxidation preventing metal layer is formed on a pad electrode, and the oxidation preventing metal layer is exposed at an opening region formed in a spin coat resin film at a portion above the pad electrode. In addition, a plating metal layer and a copper plated layer are formed on the oxidation preventing metal layer. With this structure, the resistance value above the pad electrode is reduced because the top surface of the pad electrode is difficult to oxidize, and the oxidation preventing metal layer having considerably smaller sheet resistivity than an oxidation film serves as part of a current path.

Abstract: In a semiconductor device according to the present invention, a plurality of opening regions 5 to 8 are formed in an insulating film on a pad electrode 3. A metal layer 9 formed on the pad electrode 3 has a plurality of concave portions 10 to 13 formed therein by covering the opening regions 5 to 8. Moreover, in a peripheral portion at a bottom of each of the concave portions 10 to 13 in the metal layer 9, the metal layer 9 and a Cu plating layer 19 react with each other. By use of this structure, the metal reaction area serves as a current path on the pad electrode 3. Thus, a resistance value on the pad electrode 3 is reduced.
