A wiring structure in a semiconductor device includes a substrate; a first conductive layer on the substrate; a second conductive layer covering a portion of the first conductive layer, wherein another portion of the first conductive layer is not covered by the second conductive layer; an insulation layer on the first and second conductive layer; a penetrating part passing through the insulation layer from the uncovered portion of the first conductive layer; and a third conductive layer on the insulation layer, the third conductive layer connecting the penetrating part.
