Patent ID: 7408611

Claim:
An electronic apparatus comprising; a conductive layer having a top surface and a bottom surface, the bottom surface in at least partial contact with a substrate, the electronic apparatus further comprising a metal layer of a material having a resistivity lower than that of the conductive layer, the metal layer being extended on the top surface of the conductive layer, the conductive layer having an oxidation resistivity higher than that of the metal layer and forming a terminal for connecting to peripheral circuitry, wherein: the metal layer extends on an extending portion of the top surface of the conductive layer outside the terminal of the conductive layer, and/or on the periphery of or in the vicinity of a coupling area for making the conductive layer to be exposed to the exterior within an area of the terminal of the conductive layer; and there is provided an electrically insulating layer which covers at least a part of the terminal of the conductive layer and the whole of the metal layer and which extends on the area other than the coupling area within the area of the terminal of the conductive layer.
