Abstract:
A multistack package is provided to eliminate the necessity of an additional carrier frame for supporting a thin substrate in respectively fabricating first and second packages by reducing the total thickness of a multistack package without decreasing the thickness of each package. A first opening(120h) is formed in a predetermined position of a first package(102) including a first substrate(120) and a first semiconductor chip. The first substrate has first and second surfaces(120a,120b). The first semiconductor chip is fixed to a position on the first surface of the first substrate, electrically connected to the first substrate. A second package(104) is electrically connected to the first substrate, including a second substrate(140) and a second semiconductor chip. The second substrate has third and fourth surfaces(140a,140b). The second semiconductor chip is inserted into the first opening, fixed to a position on the third surface of the second substrate while being electrically connected to the second substrate. A joint(170,180) is formed between the second surface of the first substrate and the third surface of the second substrate in the periphery of the first opening to electrically connect the first and second packages. The second semiconductor chip can be inserted into the first opening, sealed by a sealing material(168).

본 발명은 반도체 패키지의 게이트 버어(gate burr) 제거 방법에 관한 것으로, 탑 게이트 몰딩(top gate molding) 방법으로 수지 봉합부가 형성되는 반도체 패키지의 경우 수지 봉합부의 상부면에 게이트 버어가 잔존할 수 있다. 이 게이트 버어가 잔존하는 반도체 패키지를 하부 패키지로 사용하여 상부 패키지를 적층할 경우 게이트 버어로 인해 상부 패키지의 솔더 조인트(solder joint) 신뢰성이 떨어진다. 본 발명은 상기한 문제점을 해소하기 위해서, 수지 봉합부의 상부면에 잔존하는 게이트 버어 크기를 체크한 후, 체크된 정보를 바탕으로 설정된 레이저빔(laser beam)을 게이트 버어에 조사(照射)하여 제거하는 반도체 패키지의 게이트 버어 제거 방법을 제공한다. 특히 게이트 버어 제거 단계는 기존의 레이저 마킹(laser marking) 공정에서 함께 진행함으로써, 게이트 버어 제거를 위한 별도의 설비를 구비할 필요가 없고, 게이트 버어 제거 단계로 인한 반도체 패키지 제조 공정 시간이 길어지는 문제를 최소화할 수 있다. 탑 게이트 몰딩, 게이트 버어, 솔더 조인트, 적층, 멀티
