Abstract

유전적으로 적층되고 순차 가공된 2개의 회로판(100)의 선택 부위를 금속화시키는 방법을 포토데피니션에 의해 수지 A(204)를 노출하는 것을 포함한다. 수지 A(204)는 수지 전반에 걸쳐 균일하게 혼합된 Cu2O 입자(300) 10중량% 또는 그 이하를 함유한다. 회로판(100)을 환원 용액으로 분무시켜 우세하게는 Cu0또는 CuH의 촉매 섬(301)을 형성한다. 그 다음, 회로판(100)을 무전해 도금하여 수지 A가 노출되어 있는 콘덕터, 패드, 바이어를 형성한다. 환원 용액은 1급 환원제, 2급 환원제 및 포착제를 함유한다. 환원 용액의 pH는 바람직하게는 10 또는 그 이상이다. 1급 환원제는 바람직하게는 붕소수소화물이다. 2급 환원제는 바람직하게는 요오드화물이며 포착제는 킬레이트화제, 바람직하게는 EDTA이다.
