Abstract

본 발명은 적층형 세라믹 커패시터(Multi-layer Ceramic Capacitor, MLCC)의 제조방법에 관한 것으로, 좀 더 구체적으로는 상기 MLCC의 최상부 및 최하부층을 제외한 내부층은 일반적인 {Pb(Mg1/3Nb2/3)O3}x-{Pb(Zn1/3Nb2/3)O3}y-{BaTiO3}z의 조성물로 구성하고 (상기 조성식에서 0.625≤x≤0.875, 0≤y≤0.375, 0≤z≤0.04) 최상부 및 최하부층은 상기 조성물에 대하여 2~6wt%의 Pb0를 첨가한 물질로 구성하여 적층형 세라믹 커패시터를 제조하는 방법에 관한 것이다.
본 발명에 의핸 만들어진 제품은 1100℃이하의 저온에서 소결할 수 있기 때문에 적층형 세라믹 커패시터로 사용할 경우 내부전극의 가격을 크게 낮출수 있고 유전율이 12,000이상이고 유전손실이 낮을 뿐 아니라 치밀한 구조를 갖기 때문에 높은 신뢰성을 얻게 된다. 또한 소결과정에서 생기는 Pb0의 휘발에 의한 제품의 휨이나 제품내의 특성불균질을 억제하는 효과가 크기 때문에 수율 및 특성의 안정화에 크게 기여할 것이다. 또한 Pb0 분압조절을 위한 분위기 분말 및 밀폐소결의 필요성이 없어짐으로 작업공수를 줄여 생산성을 향상시키는 장점이 있다.
