Method for making three-dimensional structures. A template is provided having
at least two conductive regions separated by a non-conductive region. The template
is disposed in an electrolyte in an electrodeposition cell and a voltage is established
between one of the conductive regions and an electrode in the cell. Material is
deposited on the one of the conductive regions connected to the voltage and subsequently
bridges to the other conductive region with material deposition continuing on both
of the at least two regions. The non conductive region may be a gap and the gap
dimension is selected to regulate height differences between the at least two conductive regions.
