Abstract

본 발명은 반도체소자의 초저접합 형성방법에 관한 것으로, 반도체기판에 소자분리절연막, 게이트산화막, 게이트 전극을 형성하고, 상기 반도체 기판의 활성영역에 제1절연막을 소정두께 형성한 다음, 상기 활성영역에 불순물 이온의 일정량을 일정한 주입에너지로 주입하여 불순물 이온주입영역을 형성하고, 상기 제1절연막을 제거한다음, 상기 반도체기판을 단시간 급속 열처리하고, 전체표면상부에 층간절연막인 제2절연막과 평탄화층인 제3절연막을 연속적으로 형성한 다음, 상기 반도체기판을 튜브 열처리하여 불순물 이온주입영역을 초저접합인 소오스/드레인 접합영역으로 형성함으로써 종래기술과 동일한 이온주입 및 튜브 열처리 조건으로 훨씬 얕으며, 낮은 면저항과 접합누설전류를 갖는 접합을 형성하여 반도체소자의 수율을 향상시키고, 단시간 급속 열처리를 통해 점결함을 제거하여 후속 층간절연막 평탄화를 위한 튜브 열처리 온도 및 시간을 선정하는데 제약을 완화시킴으로써 공정여유도를 확보하여 반도체소자의 특성을 향상시키고 그에 따른 반도체소자의 신뢰성 향상 및 고집적화를 가능하게 하는 기술이다.
