Abstract:
A method of making an imprinted micro-wire structure includes providing a substrate having an edge area and a central area separate from the edge area and providing a first stamp and a multi-level second stamp. A curable bottom layer and multi-layer are provided on the substrate. A bottom-layer micro-channel is imprinted in the bottom layer. A multi-layer micro-channel and a top-layer micro-channel are imprinted in the multi-layer. Micro-wires are formed in each micro-channel. The bottom-layer micro-wire extends from the central area into the edge area. The multi-layer micro-wire contacts the bottom-layer micro-wire in the edge area. The top-layer micro-wire is over the central area and is separate from the multi-layer micro-wire and the bottom-layer micro-channel. The bottom-layer micro-wire is electrically connected to the multi-layer micro-wire and is electrically isolated from the top-layer micro-wire.
