Claim Text:
1. A method for producing an alumina template, comprising the steps of: step A: depositing a first metal in a substrate thin film, and depositing a second metal on said first metal film to form a graphic conductive layer; step B: depositing an alumina membrane on said graphic conductive layer thin film to form an oxidization ready alumina template; step C: immersing said oxidization ready alumina template in an acid solution to anodize at least once and turn said aluminum membrane into anodic alumina, removing the barrier layer from the bottom of said anodic alumina, and forming a plurality number of holes connecting to said graphic conductive layer to form an alumina template, and wherein the anodic alumina is deposited on said graphic conductive layer such that some parts of said anodic alumina are in direct contact with said first metal, and the other parts of said anodic alumina are in direct contact with said second metal.
