Abstract
Description
상기 단위칩은 콘택홀들이 일정한 형태로 형성된 셀 어레이 영역과 그 외의 주변회로 영역을 포함할 수 있다. 상기 콘택홀들의 미개구 판단은 상기 측정된 단위칩의 표면의 포화 전압과 미리 설정되어 있는 단위칩의 포화전압간의 차이로 판단할 수 있다.
상기 단위칩은 콘택홀들이 일정한 형태로 형성된 셀 어레이 영역을 포함할 수 있다. 상기 전압 감소 현상이 발생하지 않을 경우 콘택홀들의 미개구 판단은 상기 측정된 단위칩의 표면 전압의 포화 전압과 미리 설정되어 있는 단위칩의 포화전압간의 차이로 판단할 수 있다.
