Abstract:
1. A method of manufacturing a nanodot using a self-ordered template, the method comprising: performing a first anodizing to form a first alumina layer having an array of a plurality of channels on a template containing an aluminum layer; etching the first alumina layer to a predetermined depth and forming a plurality of concave portions, each of which corresponds to the bottom of each channel of the first alumina layer, on the aluminum layer; performing second anodizing to form a second alumina layer having an array of a plurality of channels corresponding to the plurality of concave portions on the aluminum layer; forming a mask layer that covers a processing object layer on a substrate where the processing object layer has been formed; performing compression molding on the mask layer using the second alumina layer in the template and transferring the profile of the channel array in the second alumina layer to the mask layer; and etching the mask layer and the underlying processing object layer and transferring the compression molded profile of the mask layer to the processing object layer.
