Claim 0:
1. A method for manufacturing an electronic device, comprising:
providing a substrate with a first major surface comprising a microchannel, wherein the microchannel has a first end and a second end, wherein the second end of the microchannel terminates in a bore extending from the first major surface of the substrate to a second major surface of the substrate opposite the first major surface;
dispensing a conductive liquid in the microchannel to cause the conductive liquid to move, primarily by capillary pressure, in a first direction toward the first end of the microchannel and in a second direction toward the second end of the microchannel; and
solidifying the conductive liquid to form an electrically conductive trace electrically connecting a first electronic device at the first end of the microchannel to a second electronic device at the second end of the microchannel, wherein the first electronic device is on the first major surface of the substrate and the second electronic device is on the second major surface of the substrate and underlying the bore.
