A two-dimensional, periodic array of nano-sized holes was fabricated in an indium tin oxide (ITO) layer, deposited onto a glass substrate with nanoimprint lithography. As a result of a thermally curing imprint process, hole array patterns with a diameter of 130 nm and a pitch of 520 nm were formed on the ITO surface with a near zero residual layer. After inductively coupled plasma etching process of ITO using the imprinted polymer pattern as an etch mask, a tapered-hole array pattern was fabricated on the ITO layer, thereby producing a prominent diffusion phenomenon in the near ultraviolet region.
