1. A method of making an electrochemical-deposition printhead, the method comprising steps of:
forming deposition anodes by filling openings with a conductive material, the openings extending from a top surface to a bottom surface of a substrate that comprises an insulating material; and
coupling the deposition anodes to a backplane, wherein the backplane comprises:
a grid control circuit, comprising an array of row traces, an array of column traces, a row driver circuit, electrically coupled to the row traces, and a column driver circuit, electrically coupled to the column traces;
a power distribution circuit; and
deposition-control circuits, aligned with a deposition grid, wherein each of the deposition-control circuits is electrically coupled to the power distribution circuit, an associated one of the row traces, and an associated one of the column traces.
