Abstract

본 발명은 LCD모듈 실장방법에 관한것으로, 특히 기판 부착시 범프 또는 와이어를 형성하지 않고, 이방성 접착제를 이용하여 IC칩 LCD 또는 보드에 실장함으로써 경박단소형화의 모듈을 형성할 수 있는 LCD모듈 실장방법에 관한 것으로, 반도체 IC를 LCD소자 또는 보드에 부착시키는 공정에서 있어서 종래의 범프 형성을 부착시키는 공정을 배제하고, 기존의 금속 전극부의 소정 부분을 절연 패턴을 이용하여 노출시키고, IC칩과 LCD 또는 보드 사이에 도전형 볼을 포함한 이방성 도전성 접착제 삽입하여 실장함으로써 범프 형성공정의 배제로 기술적 난이도를 줄일 수 있고, 절연층으로 IC의 도전 영역의 폭을 원하는 대로 노출시킬 수 있고, 와이어 본딩 공정의 배제로 경박단소한 모듈을 구성할 수 있으며, 금속 대 금속의 본딩시 오정렬을 방지할 수 있어 소자의 신뢰성을 향상시킬 수 있다.The present invention relates to a method for mounting an LCD module, and in particular, without mounting bumps or wires when attaching a substrate, an LCD module mounting method capable of forming a thin and thin module by mounting on an IC chip LCD or board using an anisotropic adhesive. In the step of attaching the semiconductor IC to the LCD element or board, except for the step of attaching the conventional bump formation, to expose a predetermined portion of the existing metal electrode portion using an insulating pattern, IC chip and LCD or By inserting and mounting an anisotropic conductive adhesive including a conductive ball between boards, the technical difficulty can be reduced by eliminating the bump forming process, and the width of the conductive region of the IC can be exposed as desired with an insulating layer, and the wire bonding process is eliminated. It is possible to configure a light and simple module, and to prevent misalignment when bonding metal to metal. It is possible to improve the reliability.
