Abstract
본 발명은 분리된 다이패드를 이용한 반도체 칩 패키지 및 제조 방법에 관한 것으로, 연장된 타이바들을 갖는 패드리스 리드프레임은 시탬핑(stamping)법에 의해 제작되고, 분리된 다이패드의 하부면은 식각(etching)법에 의해 딤플(dimple)이 형성되고, 열압착 방법에 의해 다이패드와 연장된 타이바들이 접착됨으로써, 리드프레임의 제조에 있어서 대향 생산 및 저렴한 단가를 실현하는 동시에 다이패드의 평탄도를 유지할 수 있으며, 딤플의 형성이 용이한 장점이 있다.The present invention relates to a semiconductor chip package and a manufacturing method using a separate die pad, wherein a padless lead frame having extended tie bars is manufactured by a stamping method, and the bottom surface of the separated die pad is etched. Dimples are formed by the etching method, and the die pads and the extended tie bars are bonded by the thermocompression method, thereby achieving opposing production and low cost in the manufacture of the lead frame, and at the same time flatness of the die pads. It can be maintained, there is an advantage that the formation of the dimple is easy.
