Claims (3)
- 쌍극자 트랜지스터용 콜렉터의 제조방법에 있어서, 실리콘 기판(21)에 고농도의 불순물이 주입된 서브콜렉터(22)와 시리콘 콜렉터(23) 및 절연막(24)을 순차적으로 형성하는 제1공정과; 상기 절연막(24) 및 상기 실리콘 콜렉터(23)를 패터닝(patterning)하여 상기 서브콜렉터(22) 위에 활성영역을 정의한 후, 상기 실리콘 콜렉터(23)의 양측면에 측벽막(25)을 형성하는 제2공정과; 고융점 금속박막을 증착하고 열처리하여 상기 서브콜렉터(22)상의 정의된 활성영역 이외의 영역에만 선택적으로 실리사이드(26)를 형성시킨 후, 상기 측벽막(25)과 상기 절연막(24) 위에 잔류하는 금속박막을 제거하는 제3공정과; 상기 기판 상부의 전면을 충분히 피복할 수 있을 정도의 두께로 산화막(27)을 도포하는 제4공정과; 상기 산화막(27)을 평탄화하고 상기 절연막(24)을 제거하는 제5공정으로 구성되어 콜렉터 기생저항을 크게 줄여 초고주파 응답특성이 우수한 쌍극자 트랜지스터용 콜렉터 제조방법.
- 제1항에 있어서, 상기 제2공정에서의 상기 고융점 금속 박막은 티타늄(Ti), 텅스텐(W), 몰리브덴(Mo), 코발트(Co), 탄탈륨(Ta), 지르코늄(Zr), 바나듐(V), 니오븀(Nb) 및 크롬(Cr) 중의 어느 하나로 구성된 것을 사용하여 선택적 금속 실리사이드(26)를 형성하는 것을 특징으로 하는 쌍극자 트랜지스터용 콜렉터 제조방법.
- 제1항에 있어서, 상기 측벽막(25)을 형성하는 제2공정에 있어서 단층구조의 질화막(Si3N4) 대신 산화막(SiO2)/질화막 혹은 산화막/질화막/산화막과 같은 다층구조를 이용하여 상기 측벽막(25)을 형성할 수 있는 것을 특징으로 하는 쌍극자 트랜지스터용 콜렉터 제조방법.
