Abstract
본 발명은 반도체 소자의 제조공정 중 포토리소그라피 (photolithography) 공정시 2개 이상의 마스크를 연속해서 노광할 경우 상호 중첩오차를 측정할 수 있는 중청오차 측정장치에 관한 것으로, 빛이 투과되는 영역이 형성하고자 하는 패턴 및 패턴간 간격의 두배인 외부박스(1")와 빛이 투과되지 못하는 영역이 형성하고자 하는 패턴보다 소정정도 크게 형성된 내부박스(4)를 구비한 하나의 마스크와; 빛이 투과되는 영역이 형성하고자 하는 패턴 및 패턴간 간격의 두배보다 소정정도 작게 형성된 외부박스(6)와 빛이 투과되지 못하는 영역이 형성하고자 하는 패턴과 동일한 크기로 형성된 내부박스(4)를 구비한 다른 하나의 마스크가 포개어진 구조를 이룸으로써 식각공정 없이 다중마스크의 중첩오차 측정이 가능하여 공정단순화 효과를 얻을 수 있다.The present invention relates to a heavy-duty error measuring device that can measure overlapping errors when two or more masks are continuously exposed during a photolithography process of a semiconductor device manufacturing process. A mask having an outer box 1 ", which is twice the distance between the pattern and the pattern, and an inner box 4 formed to a predetermined degree larger than the pattern to which light cannot be transmitted; Another mask having an outer box 6 formed to be smaller than the pattern to be formed and the distance between the patterns by a predetermined degree and an inner box 4 formed to have the same size as the pattern to which the light-permeable region is to be formed. By forming a superimposed structure, it is possible to measure overlapping errors of multiple masks without an etching process, thereby obtaining a process simplification effect.
