초록

최근 RFID, 유연디스플레이, 태양전지, 전자 종이 등의 소자를 프린팅 방식을 이용하여 생산하려는 연구가 활발하게 진행 되고 있다. 이런 방식이 기존의 노광기술과 식각기술에 의존하는 반도체 공정에 비해 가격 경쟁력에서 우수하기 때문이다. 특히 RFID, 유연디스플레이, 태양전지, 전자 종이 등은 유연성과 대량생산을 필요로 하기 때문에 롤투롤(roll to roll)공정과 같은 저가격화, 대형생산화에 관심이 집중되고 있다. 이 롤투롤 기술을 사용하기 위해서는 인쇄 패턴의 빠른 구현, 표면 균일도, 두께 등의 높은 인쇄 품질이 보장 되어야 한다. 본 연구는 실험계획법(Design of Experiment)을 적용하여 인자들의 주효과와 교호작용 효과를 분석하고, 롤투롤 전자인쇄 시스템에서 닙 롤의 특성에 따른 인쇄 품질의 영향과 인쇄 품질의 향상 방안을 찾기 위한 매칭기술을 제안 하였다.

Currently, active research is being performed on printing of electronic devices such as RFID devices, flexible displays, solar cells, and e-paper. This technique has several advantages over existing technologies such as lithography and etching. In particular, RFID devices, flexible displays, solar cells, and e-paper require flexibility and a mass production system. Thus, attention is being focused on the roll-to-roll process. High quality should be guaranteed in the roll-to-roll printed electronics systems, and good thickness and roughness qualities must be ensured. Experimental design was applied to this problem to analyze the main effects and interaction effects of various factors. Matching technology between the nip roll characteristics and the quality of the print pattern in roll-to-roll printed electronics systems was proposed to improve the printing quality.
