Nickel stamps with micro and nano-scale relief features on their surfaces have been fabricated using proton beam writing coupled with nickel sulfamate electroplating. A focused beam of sub-micron 2.0 MeV protons was used to direct-write 3D patterns into spin coated PMMA resist, and a single step nic
