Method to assemble nano-structure on a substrate and nano-molecule device comprising nano-structure formed thereby

摘要

A method of selectively positioning nanostructures on a substrate is provided which includes: a first step of forming a photoresist pattern on the substrate and then control the line width of the photoresist pattern in a nano unit to form a nanometer photoresist layer; a second step of forming a protective layer for preventing adsorption of a nano-material in a patter-unformed area on the substrate on which the nanometer photoresist layer has been formed; a third step of removing the photoresist layer formed on the substrate; a fourth step of forming a positively-charged or negatively charged adsorbent layer in the area from which the photoresist layer has been removed; and a fifth step of applying a nano-material-containing solution charged in the opposite polarity of the adsorbent layer to the substrate on which the adsorbent layer has been formed.
