High aspect ratio gratings fabricated by electrodeposition

A method is provided for making gratings of gold or other metal in silicon substrates. The disclosed method may achieve high aspect ratios. According to the disclosed method, a silicon wafer is through-etched. A seed layer of metal is vapor-deposited on one side of the wafer, and a layer of metal is electrodeposited on the seed layer. The electrodeposited metal plugs the trenches and provides a conductive surface for subsequent electrodeposition. The trenches are then filled by electrodeposition from within the trenches, so that the walls of the metal grating grow on the metal plugs.
