Abstract

In this research, developed full-scan photoresist coating system(FPCS) can improve the efficiency of the photoresist coating system essential for spinner equipment in nano semiconductor manufacturing process. The devices developed in this research, which can be swiftly replaced in case abnormal state element changes or wafer manufacturing defect occurs, are anticipated to improve module yield as well as real-time monitoring on the state element in order to prevent the complex process defect due to the photoresist miss coating.

본 연구에서는 Nano급 반도체 생산공정에서 필수적인 스피너(spinner) 설비의 감광액 도포(photo resist coating)시스템의 효율을 획기적으로 개선할 수 있는 새로운 완전스캔(Full-scan) 방식의 감광액 도포시스템(FPCS : Full-scan Photo-resist Coating System)을 개발하였다. 또한, 감광액의 미 도포로 인한 복합적인 공정불량을 예방하기 위하여 실시간(real-time)으로 상태요소들을 감시할 뿐만 아니라 상태요소의 비정상적 변화나 웨이퍼 가공불량이 발생할 경우 해당 유니트(unit)를 정지시킴과 동시에 원격지에 있는 엔지니어에게 경보를 전송함으로써 즉각적인 대처가 가능할 수 있도록 개발하였다.
