Abstract: Provided are a method for manufacturing a nano-pattern including: increasing a temperature of a self-assembling material applied on a substrate through light irradiation to form a self-assembly pattern, and a nano-pattern manufactured thereby. More particularly, the present invention relates to a method for manufacturing a nano-pattern capable of implementing various circuit patterns through simple dragging without using a photoresist pattern or chemical pattern in advance, implementing the nano-pattern on a substrate having a three-dimensional structure such as a flexible substrate as well as a flat substrate, and performing a process without a specific environmental restriction. In addition, the present invention relates to a method for manufacturing a nano-pattern capable of forming a large-area self-assembly pattern within a very short time, that is, several to several ten milliseconds (ms) by instantly irradiating high-energy flash light to instantly perform thermal annealing.

Abstract: The present invention relates to a device for a physical unclonable function having unique characteristics, and the device for a physical unclonable function according to the present invention includes a nano-pattern corresponding to a self-assembled structure. As the device for a physical unclonable function according to the present invention has a PUF pattern based on a self-assembled structure formed by spontaneous phase separation behavior of a block copolymer having non-deterministic characteristics, the device for a physical unclonable function may have unclonable unique characteristics.
