Abstract: A method for forming a fine pattern includes forming an etching target material layer on a substrate, forming a first photoresist layer on the etching target material layer, forming a metal pattern on the first photoresist layer, the metal pattern having a plurality of lines and thin film lines alternately arranged, the lines having predetermined linewidth and thickness and are spaced apart from each other by a predetermined distance, exciting surface plasmons in the metal pattern by light irradiation to produce a surface plasmon resonance that exposes a fine first pattern shape in the first photoresist layer, forming a first photoresist pattern by removing the metal pattern and developing the first photoresist layer, and etching the etching target material layer by using the first photoresist pattern as a mask.

Abstract translation: 形成精细图案的方法包括在基板上形成蚀刻目标材料层，在蚀刻靶材料层上形成第一光致抗蚀剂层，在第一光致抗蚀剂层上形成金属图案，金属图案具有多条线，薄 膜线交替布置，线具有预定的线宽和厚度并且彼此隔开预定距离，通过光照射激发金属图案中的表面等离子体激元，以产生表面等离子体共振，其在第一 光致抗蚀剂层，通过去除金属图案和显影第一光致抗蚀剂层形成第一光致抗蚀剂图案，并且通过使用第一光致抗蚀剂图案作为掩模来蚀刻蚀刻目标材料层。
