Abstract
[해결수단] 플렉시블 기판(10)은, 폴리이미드 필름(11)과, 폴리이미드 필름(11)의 표면에 형성되어 있는 하지 금속층(12)과, 하지 금속층(12)에 중첩하여 형성되어 있는 구리 도체층(13)을 포함하여 구성되어 있다. 하지 금속층(12)은, 크롬 함유 합금층(14)을 포함하고 있다. 그리고 이 크롬 함유 합금층(14)이, 폴리이미드 필름(11)과 접하는 제1 금속층(14a)과, 제1 금속층(14a)에 중첩하도록 위치하는 제2 금속층(14b)을 가지고, 제1 금속층(14a)에 있어서의 크롬의 중량 퍼센트가, 제2 금속층(14b)에 있어서의 크롬의 중량 퍼센트보다 크다. 이 구성에 의해, 제1 금속층(14a)에 대한 구리의 확산을 억제할 수 있고, 내열 필 강도의 저하를 억제할 수 있다. 또한, 플렉시블 기판(10)의 제조 비용을 억제할 수 있다.
Description
도 2는 본 발명의 제1 실시형태에 따른 플렉시블 기판의 단면도이다.
도 3은 본 발명의 제1 실시형태에 따른 플렉시블 기판의 TEM에 의한 원소 맵핑의 측정도이다. (도 A) 과열 수증기 처리 후의 Cr 원소의 분포 상태를 나타내는 도면이다. (도 B) 과열 수증기 처리 전의 Cr 원소의 분포 상태를 나타내는 도면이다. (도 C) 과열 수증기 처리 후의 Cu 원소의 분포 상태를 나타내는 도면이다. (도 D) 과열 수증기 처리 전의 Cu 원소의 분포 상태를 나타내는 도면이다.

Claims (2)
- 폴리이미드 필름과,
상기 폴리이미드 필름의 표면에 형성되어 있는 하지(下地) 금속층과,
상기 하지 금속층에 중첩하여 형성되어 있는 구리 도체층을 포함하여 구성되어 있고,
상기 하지 금속층은, 크롬 함유 금속층을 포함하고 있고,
상기 크롬 함유 금속층은, 상기 폴리이미드 필름과 접하는 제1 금속층과, 상기 제1 금속층에 중첩하도록 위치하는 제2 금속층을 가지며,
상기 제1 금속층에 있어서의 크롬의 중량 퍼센트가, 상기 제2 금속층에 있어서의 크롬의 중량 퍼센트보다 큰 것을 특징으로 하는 플렉시블 기판. - 제1항에 있어서, 상기 크롬 함유 금속층은 니켈 크롬 합금층인 것을 특징으로 하는 플렉시블 기판.
