Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 특징에 따른 적층 필름 콘덴서를 제조하는 시스템을 나타낸 계층도,
제2도와 제3도는 각 콘덴서를 제조하고 제조한후를 각각 나타낸 개략적 측단면도.
Claims (4)
- 콘덴서에 이루어진 주변 절단 측면을 통하여 콘덴서 외부에 노출된 유전체층과 필름 전국의 두 주변모서리가 서로 교대로 적층되는 다수의 유전체층과 대응하는 수의 필름전극으로 이루어지고 각 유전체층이 각 필름전극용 물질보다 더 낮은 자외선 레이저 비임을 갖는 물질로 이루어지는 적층 필름 콘덴서의 제조방법으로 이 방법이 콘덴서의 주변 절단측면에 인접하여 위치하는 필름 전극의 주변 모서리를 우선 제거하기 위하여 주변 절단 측면에 자외선 레이저 비임을 방사하는 단계로 이루어짐을 특징으로 하는 제조방법.
- 제1항에 있어서, 자외선 레이저 비임이 0.4㎛ 이하의 파장을 가짐을 특징으로 하는 제조방법.
- 제1항에 있어서, 자외선 레이저 비임이 엑시더 레이저 비임임을 특징으로 하는 제조방법.
- 제1항에 있어서, 자외선 레이저 비임이 맥동 자외선 레이저 비임임을 특징으로 하는 제조방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
