Web1 apr. 2006 · Nickel micro-gears were fabricated using optical projection lithography on copper-clad plastic substrates and nickel electroplating. Adopting low numerical-aperture projection exposure, large depth-of-focus was secured, and SU-8 resist moulds with vertical sidewalls were fabricated. WebAdvantages of Photolithography. Photolithography can create patterns with extremely small features – down to a few tens of nanometers – while also enabling incredibly precise control over feature geometry. Photolithography is also comparatively fast, capable of creating patterns over an entire silicon wafer with relatively low cost.
