Abstract:
본 발명의 탭 패키지용 반도체칩은, 탭 패키지 제조를 위하여 필름상에 탭 실장되는 탭 패키지용 반도체칩이다. 이 탭 패키지용 반도체칩은, 필름에 부착되는 제1 면 및 반대되는 제2 면을 갖는 칩 본체와, 칩 본체의 제1 면에서 상부, 하부 및 측부에 각각 배치되는 복수개의 칩 패드들을 구비한다. 칩 본체는 중심부분에 배치되는 중심영역을 기준으로 양 방향으로 가장자리에 이르기까지 구별되는 복수개의 영역들을 가지며, 칩 패드들 중 인접한 칩 패드들 사이의 간격은 복수개의 영역들에서 서로 다르다. 이에 따르면 실장공정 중에 가해지는 열로 인한 열변형 현상이 발생하더라도 반도체칩의 칩패드와 필름의 패드 사이의 오정렬이 발생하는 것을 억제시킬 수 있다.
