Abstract
Spatially selective electrochemical deposition of a metal (Ni) into the ordered nanohole-array structure of anodic porous alumina was performed using a microelectrode. A patterned deposit consisting of fine Ni cylinders of 70 nm diameter was obtained in the hole-array structure with spatial resolution on the order of tens of micrometers, and its size was in good agreement with that of the microelectrode used as a tip.
