Abstract:
1. A multiplexer/demultiplexer for nanoscale circuits comprising: (a) a substrate having a major surface; (b) a plurality of bottom communication wires formed on said major surface; (c) a polymeric film having a plurality of first recesses and a plurality of second recesses, wherein said first recesses are deeper than said second recesses and wherein said first recesses expose portions on one or more of said bottom communication wires; and (d) a metal layer formed in the bottom of both said first recesses and said second recesses that forms wires that cross over said bottom communication wires at a non-zero angle, whereby said wires in said second recesses do not make electrical contact with said bottom communication wire and whereby said wires in said first recesses do make electrical contact with said bottom communication wire.
