摘要: A method for fabricating a large-area nanoscale pattern includes: forming multilayer main thin films isolated by passivation layers; patterning a first main thin film to form a first main pattern; forming a first spacer pattern with respect to the first main pattern; and forming a second main pattern by transferring the first spacer pattern onto a second main thin film. By using multilayer main thin films isolated by different passivation films, spacer lithography capable of reducing a pattern pitch can be repetitively performed, and the pattern pitch is repetitively reduced without shape distortion after formation of micrometer-scale patterns, thereby forming nanometer-scale fine patterns uniformly over a wide area.
