Abstract

본 발명에 따르면 MOSFET 제조공정에서 드레인 및 소오스영역이 형성될 실리콘 기판을 식각시킨 후에 이온주입을 실시하여 드레인 및 소오스영역을 형성시켰기 때문에 채널이 기판표면보다 아래에 형성되어 핫 케리어 효과를 예방한다.

Claims (1)

  1. 제1도전형을 갖는 실리콘 기판위에 필드영역과 액티브영역을 한정한 후 상기 액티브영역의 소정부분에 게이트와 캡게이트 절연막을 형성하는 공정과, 게이트와 필드영역사이의 액티브영역의 상기 실리콘 기판을 소정깊이까지 식각한 후 상기 식각된 실리콘 기판내에 제1도전형과 반대되는 극성을 갖는 저농도의 제2도전형을 갖는 이온주입을 실시하여 저농도의 드레인 및 소오스영역을 형성시키는 공정과, 상기 게이트의 양측에 측벽을 형성시킨 후 상기 고농도의 드레인 및 소오스영역내에 고농도의 제2도전형을 갖는 이온주입을 실시하여 고농도의 드레인 및 소오스영역을 형성시키는 공정을 순차적으로 실시함을 특징으로 하는 MOSFET 제조방법.
