Making micro-wires with different heights

A method of making a transparent conductor structure, comprising:

• providing a transparent conductor precursor structure including a transparent substrate, a first precursor material layer formed over the transparent substrate and a second precursor material layer formed on the first precursor material layer;
• forming within a first transparent conductor area a plurality of electrically connected first micro-wires in the first and second precursor material layers;
• forming within a second transparent conductor area a plurality of electrically connected second micro-wires in either the first precursor material layer or the second precursor material layer, the second micro-wires electrically connected to the first micro-wires;
• and
• wherein the height of at least a portion of the first micro-wires is greater than the height of at least a portion of the second micro-wires, and wherein the total area occupied by the first micro-wires is less than 15% of the first transparent conductor area and the total area occupied by the second micro-wires is less than 15% of the second transparent conductor area;
• and
• further including:
• forming the one or more first micro-wires and a portion of each of the one or more second micro-wires in a first step and forming the remainder of the one or more first micro-wires in a second step after the first step;
• forming the first precursor material layer by depositing first precursor material in the first transparent conductor area and in the second transparent conductor area;
• pattern-wise processing the first precursor material;
• forming the second precursor material layer by depositing second precursor material in the first transparent conductor area;
• and
• pattern-wise processing the second precursor material.
