In a method for communication between a first station and a second station the first station may provide the second station with information associated with the manner how the second station should transmit towards the first station. The invention provides a reliable and durable interconnect for both structural and electrical components of such devices. The semiconductor device comprises a substrate, a plurality of gate electrodes protruding on the substrate, a blanket dielectric layer overlying the substrate and gate electrodes, and a plurality of polycrystalline silicon plugs, respectively disposed on the substrate between the gate electrodes, in the dielectric layer.
