Description
Claims (4)
- 사이목스(SIMOX) 웨이퍼의 제작방법에 있어서, 실리콘 기판(1)에 산소이온 주입공정을 통하여 손상된 실리콘 영역(2), SiO2층(3) 및 Si+SiO2 층(4)을 형성시키는 단계와, 상기 단계로부터 1차 열처리공정을 실시하여 상기 및 Si+SiO2 층(4)을 SOI막(5)으로 변화시키는 단계와, 상기 단계로부터 상기 1차 열처리 공정시 SOI막(5) 상부에 성장되는 표면 산화막(6)을 HF 식각용액으로 제거시키는 단계와, 상기 단계로부터 2차 열처리공정을 실시하여 상기 SOI막(5)내에 존재하는 산소침전물(7)을 제거시키는 단계로 이루어지는 것을 특징으로 하는 사이목스 웨이퍼의 제작방법.
- 제1항에 있어서, 상기 산소이온 주입시 1 S1018이온/cm2 이상의 고농도 산소를 200KeV 정도의 에너지로 실리콘기판에 주입하는 것을 특징으로 하는 사이목스 웨이퍼의 제작 방법.
- 제1항에 있어서, 상기 1차 열처리 공정은 1200내지 1400oC 온도, 2%O2에 Ar을 혼합한 가스분위기 상태에서 5 내지 7시간 동안 실시하는 것을 특징으로 하는 사이목스 웨이퍼의 제작방법.
- 제1항에 있어서, 상기 2차 열처리 공정은 1100 내지 1300oC 온도, 순수 H2 분위기 상태에서 30분 내지 1.5시간 동안 실시하는 것을 특징으로 하는 사이목스 웨이퍼의 제작방법.
