摘要:
An interconnection structure for a semiconductor device includes an inter-level insulation layer disposed on a semiconductor substrate. First contact constructions penetrate the inter-level insulation layer. Second contact constructions penetrate the inter-level insulation layer. Metal interconnections connect the first contact constructions to the second contact constructions on the inter-level insulation layer. The first contact constructions include first and second plugs stacked in sequence and the second contact constructions include the second plug.
