Abstract

마이크로 전자 디바이스, 양호하게는 반도체 디바이스에서 와이어 접속을 이루는 방법이 본드 패드(5)를 갖는 마이크로 전자 디바이스(7) 및 리드 프레임의 리드핑거와 같이 마이크로 전자 디바이스에 외부 접속하는 본딩 로케이션(9)를 제공하는 단계를 포함한다. 와이어(1)가 리드 핑거 및 볼(21)이 먼저 접착되었던 본드 패드(5)로 접속하기 위해 제공된다. 볼(21)은 양호하게는 금으로 제조되고 본드 패드 위의 와이어 재료와 전기적 통전하는 재료로 만들어진다. 와이어의 한 단부를 볼 본드(23)에 의해 리드 핑거에 접속되고 와이어의 다른 단부는 접속을 완결하고 본드 패드위의 룹 없이도 접속을 제공하기 위해 볼(21)에 접속된다.
