Abstract

See full text

A method for forming an ultra-low density three-dimensional thin film structure made of a solid thin film, including: radiating ultraviolet rays of different patterns in respective predetermined directions to a liquid photosensitive resin bulk so as to harden a portion of the resin bulk; removing the liquid photosensitive resin which is not hardened so as to form a solid photosensitive resin structure; coating the surface of the solid photosensitive resin structure with a thin film; removing the thin film from the outermost surface of the resin bulk so as to expose the solid photosensitive resin; and removing the solid photosensitive resin structure.
