Abstract:
1. A method of making an imprinted micro-wire structure, comprising: providing a substrate; providing a first stamp and a different multi-level second stamp having at least first and second deep protrusions and one or more third shallow protrusions, the first and second deep protrusions having a depth greater than a depth of the shallow protrusion(s); providing a curable bottom layer over the substrate, wherein the curable bottom layer includes first curable material and further including locating the first stamp in contact with the first curable material and only partially curing the first curable material or wherein the curable multi-layer includes second curable material and further including locating the multi-level second stamp in contact with the second curable material and only partially curing the second curable material; forming one or more bottom-layer micro-channel(s) in the curable bottom layer by at least imprinting the curable bottom layer with the first stamp and curing the curable bottom layer; forming a bottom-layer micro-wire in each bottom-layer micro-channel; providing a curable multi-layer adjacent to and in contact with the cured bottom layer; forming at least first and second multi-layer micro-channels in a common layer and a top-layer micro-channel in the curable multi-layer in a common step by at least imprinting the curable multi-layer with the multi-level second stamp and curing the curable multi-layer, wherein either: forming a top-layer micro-wire in the top-layer micro-channel, a first multi-layer micro-wire in the first multi-layer micro-channel, and a second multi-layer micro-wire in the second multi-layer micro-channel that electrically connects the first multi-layer micro-wire to the second multi-layer micro-wire.
