Abstract
본 발명의 한 실시 양태는 반도체 웨이퍼를 1차 온도로 유지된 에칭제로부터 제거하는 단계와, 반도체 웨이퍼를 1차 온도보다 적어도 5℃ 더 저온인 2차 온도에 있는 린스 용액으로 린스하는 단계로 이루어진 웨이퍼 위의 절연체 층의 에칭을 급작스럽게 중단하는 방법이다. 바람직하게는, 절연체 층은 TEOS, BPSG, PSG, 열성장 산화물 및 그 중 어느 것의 배합물로 이루어진다. 바람직하게는, 1차 온도는 대략 25℃이고 2차 온도는 대략 0 내지 5℃이거나, 또는 1차 온도는 대략 70 내지 90℃이고 2차 온도는 대략 10 내지 30℃이다. 바람직하게는, 에칭제는 완충되거나 또는 완충되지 않은 HF 산으로 이루어지고, 린스 용액은 탈 이온수로 이루어진다. 바람직하게는, 2차 온도는 1차 온도보다 적어도 15℃ 더 저온이다.
