Patent ID: 7901586

Claim:
A method of manufacturing a nanodot based on a self-ordered nanochannel-array, the method comprising: performing first anodizing on an aluminum substrate to form a first alumina layer having a channel array formed by a plurality of cavities; etching away the first alumina layer to form a plurality of concave portions on the aluminum substrate, wherein each concave portion corresponds to the bottom of each channel of the first alumina layer; performing second anodizing on the aluminum substrate to form a second alumina layer having an array of a plurality of channels corresponding to the plurality of concave portions on the aluminum substrate; forming a mask layer on a processing object layer, wherein the processing object layer is formed on another substrate; transferring a profile of the channel array of the second alumina layer to the mask layer through compression molding; and etching the mask layer so that the profile is transferred to the processing object layer.
