Abstract:
An interconnection structure comprising:an interlayer insulating film; and first interconnection layer to which a low potential is applied and second interconnection layer to which a high potential is applied, said interlayer insulating film being interposed between said first interconnection and second interconnection layers and said first interconnection and second interconnection layers being electrically connected through a via hole formed through said interlayer insulating film; wherein overlap regions including regions facing said via hole are formed for both said first interconnection and second interconnection layers; the shortest distance from the edge of the via hole-faced region to interconnection end in said overlap region of said first interconnection layer is greater than the shortest distance from the edge of the via hole-faced region to interconnection end in said overlap region of said second interconnection layer; and the interconnection resistance of said first interconnection layer is greater than the interconnection resistance of said second interconnection layer.
