Fabrication of submicron metallic grids with interference and phase-mask holography

Abstract

Complex, submicron Cu metallic mesh nanostructures are made by electrochemical deposition using polymer templates made from photoresist. The polymer templates are fabricated with photoresist using two-beam interference holography and phase mask holography with three diffracted beams. Freestanding metallic mesh structures are made in two separate electrodepositions with perpendicular photoresist grating templates. Cu mesh square nanostructures having large (52.6%) open areas are also made by single electrodeposition with a photoresist template made with a phase mask. These structures have potential as electrodes in photonic devices. KeywordsAmes Laboratory, Physics and Astronomy RightsCopyright 2011 Society of Photo-Optical Instrumentation Engineers.
