State of the art and technological trend for the nano-imprinting lithography equipment

나노 임프린팅 리소그래피 장비의 기술개발 동향

Classical lithography in semiconductor employs stepper technologies. Limits of this technology are clearly seen at structures below 100nm. Nano-imprinting lithography is a new method for generating patterns in submicron range at reasonable cost. In order to manufacture nano-imprinting lithography(NIL) equipment, several NIL manufacturers have been developing key technologies for realization of nano-imprinting process, recently. In this paper, we've been describe state-of-the-art and technology trends for nano-imprinting lithography equipments.
