Abstract
An electrode is disposed on a semiconductor layer. A polyimide layer has an opening disposed on the electrode, covers the edge of the electrode, and extends onto the electrode. A copper layer is disposed on the electrode within the opening, and located away from the polyimide layer on the electrode. A copper wire has one end joined on the copper layer.
