  • Methods of forming nano-devices using nanostructures having self-assembly characteristics
    Patent number: 7977177
    Abstract: Provided are methods of forming nano-devices. One of the methods includes forming a nano-scale self-assembly material layer on a substrate formed of at least one layer, forming a mask layer on the self-assembly material layer, performing a surface treatment process on the substrate using the mask layer as a mask, and removing the self-assembly material layer. Accordingly, it is possible to fabricate nano-devices through a nano-scale substrate patterning process, ion implantation process and etching process, without using a light source.
    Type: Grant
