Abstract:
An interconnection structure is provided by forming a first damascene interconnect structure that directly connects a first active area in a substrate, a first conductive line on the substrate and/or a first electrode on the substrate with a second active area in the substrate, a second conductive line on the substrate and/or a second electrode on the substrate. A second damascene interconnect structure may directly connect the first active area, the first conductive line and/or the first electrode to the second active area, the second conductive line and/or the second electrode. The first active area, the first conductive line and/or the first electrode connected to the second active area, the second conductive line and/or the second electrode by the first damascene interconnect structure may be different from the first active area, the first conductive line and/or the first electrode and the second active area, the second conductive line and/or the second electrode connected by the second damascene interconnect structure.
