초록

첨가물의 형태가 X7R용 MLCC 유전 원료의 전기적 특성 및 미세구조에 미치는 영향을 평가하였다. Glass frit 및 산화물 형태로 제조된 첨가물을 분말 공정 조건을 달리하여 동일한 주조성에 첨가하였다. 미세구조 및 유전특성을 측정한 결과, glass 층에 dopant의 농도 구배가 존재하는 조성이 유전 특성이 가장 우수하였다. 최적 조성을 MLCC로 제작하여 유전 특성을 측정하였으며, X7R 제반 조건을 만족하였다.

Effects of additives on electrical properties and microstructure of MLCC X7R dielectrics have been investigated. The additives of glass frit or oxide form were added in the same main composition by the different powder processing conditions. As a result of the dielectric property and microstructure analysis, the composition having the glass layer with dopant concentration gradient showed the excellent dielectric properties. The MLCCs were fabricated with the excellent composition and all dielectric properties satisfied the X7R requirements.
