Claims (4)
- 반도체기판의 활성영역과 접촉하는 하부 전극과 그 위의 상부전극 및 상기 전극들에 내재된 고유전체 Ta2O5막으로 이루어진 커패시터의 제조 공정에 있어서,반도체 소자를 구비한 반도체기판 상부에 소자간 절연을 위한 층간 절연막의 콘택홀을 통해서 반도체 소자와 접하며 도전층으로 이루어진 하부전극을 형성하는 단계;상기 하부전극 상부면에 Ta2O5막을 형성하는 단계;상기 Ta2O5막 상부면에 NH3분위기에서 급속열공정을 실시하여 TaN막으로 이루어진 제1 상부전극을 형성하는 단계; 및상기 제 1상부전극 상부면에 도전층으로 이루어진 제 2상부전극을 형성하는 단계를 포함하여 이루어진 것을 특징으로 하는 반도체장치의 커패시터 제조방법.
- 제 1항에 있어서, 상기 TaN막의 형성을 위한 급속열공정은 650∼850℃의 온도 조건, 30∼120초의 처리 시간으로 실시하는 것을 특징으로 하는 반도체장치의 커패시터 제조방법.
- 제 1항에 있어서, 상기 TaN막의 두께는 100∼200Å으로 하는 것을 특징으로 하는 반도체장치의 커패시터 제조방법.
- 제 1항에 있어서, 상기 제 2상부전극은 불순물이 도핑된 다결정실리콘막으로 이루어지며 그 두께는 1000∼1500Å으로 하는 것을 특징으로 하는 반도체장치의 커패시터 제조방법.
