Abstract: 본 발명은 이동통신 단말기의 키 입력 장치 및 방법에 관한 것으로, 종래 이동통신 단말기의 키패드 입력 방법은 시각에 의존하는 방법을 기본으로 하기 때문에 시각이 약한 장애인이나 노령층 사용자가 이용하기 어려운 문제점이 있었다. 또한, 시각에 의존하지 않고 입력하기 위해서는 키패드에 형성된 돌기와 캐패드 구조를 촉감을 통해 확인하는 방법 뿐이므로 감각이 둔한 사용자는 용이한 사용이 어려운 문제점이 있으며, 특히 운전중과 같이 비 시각적으로 키 입력을 실시해야 하는 경우에는 키 입력이 어려운 문제점이 있었다. 이와 같은 문제점을 감안한 본 발명은 이동통신 단말기의 키 주변 혹은 키 내부에 광센서를 다수 부착하여 사용자의 움직임을 감지할 수 있도록 하고, 키패드입력 모드로서 광센서를 이용한 키 입력 모드를 선택할 수 있도록 하는 것으로 사용자 손가락이 소정의 키 근처에 접근하는 경우 해당 키의 번호를 음성으로 출력하여 사용자가 키를 구별하여 입력을 실시할 수 있도록 함으로써 시력이 약한 장애인이나 노령 사용자들이 용이하게 키를 조작할 수 있으며, 운전 중 이동통신 단말기 사용이 보다 안전해질 수 있고, 키패드를 발광시킬 필요가 없으므로 전력을 줄일 수 있는 효과가 있다.

Abstract: 본 발명은 플립 칩 패키지의 오목형 솔더 범프 구조 및 그 제조 방법에 관한 것으로서, 가운데가 오목한 오목형 솔더 범프 구조는 칩과 기판 사이의 언더필 공정이 가능할 만큼의 범프 높이를 가지면서 솔더 범프의 크기나 솔더 범프간 거리의 영향을 받지 않으므로 미세 피치의 플립 칩 패키지를 구현할 수 있다. 본 발명에 따르면, 반도체 칩의 칩 패드 위에 금속 기둥을 형성하고 금속 기둥의 표면에 솔더를 도금한 후, 솔더가 미리 도포된 기판의 기판 패드 위에 솔더가 도금된 금속 기둥을 위치시키고 솔더를 리플로우하면, 용융 솔더의 표면 장력에 의하여 가운데가 오목한 형태의 오목형 솔더 범프가 형성된다.
