Description

스택 패키지{STACK PACKAGE}Stack Package {STACK PACKAGE}

본 발명은 스택 패키지에 관한 것으로, 보다 상세하게는, 수직적(Vertical) 스택 구조와 수평적(Planar) 스택 구조를 동시에 구현한 스택 패키지에 관한 것이다.The present invention relates to a stack package, and more particularly, to a stack package which simultaneously implements a vertical stack structure and a horizontal stack structure.

반도체 산업에서 집적회로에 대한 패키징 기술은 소형화에 대한 요구 및 실장 신뢰성을 만족시키기 위해 지속적으로 발전 되고 있다. 예컨대, 소형화에 대한 요구는 칩 크기에 근접한 패키지에 대한 기술 개발을 가속화시키고 있으며, 실장 신뢰성에 대한 요구는 실장 작업의 효율성 및 실장 후의 기계적·전기적 신뢰성을 향상시킬 수 있는 패키징 기술에 대한 중요성을 부각시키고 있다. In the semiconductor industry, packaging technology for integrated circuits is continuously developed to meet the demand for miniaturization and mounting reliability. For example, the demand for miniaturization is accelerating the development of technologies for packages that are close to chip size, and the demand for mounting reliability highlights the importance of packaging technologies that can improve the efficiency of mounting operations and mechanical and electrical reliability after mounting. I'm making it.

또한, 전기·전자 제품의 소형화와 더불어 고 성능화가 요구됨에 따라, 고용량의 반도체 모듈을 제공하기 위한 다양한 기술들이 연구 개발되고 있다. In addition, as miniaturization of electric and electronic products and high performance are required, various technologies for providing a high capacity semiconductor module have been researched and developed.

고용량의 반도체 모듈을 제공하기 위한 방법으로서는 메모리 칩의 고집적화를 들 수 있으며, 이러한 고집적화는 한정된 반도체 칩의 공간 내에 보다 많은 수의 셀을 집적해 넣는 것에 의해 실현될 수 있다. As a method for providing a high capacity semiconductor module, there is a high integration of a memory chip, which can be realized by integrating a larger number of cells in a limited space of the semiconductor chip.

그러나, 이와 같은 메모리 칩의 고집적화는 정밀한 미세 선 폭을 요구하는 등, 고난도의 기술과 많은 개발 시간을 필요로 한다. 따라서, 고용량의 반도체 모듈을 제공하기 위한 다른 방법으로서 스택(Stack) 기술이 제안되었다. However, such high integration of the memory chip requires a high level of technology and a lot of development time, such as requiring a fine fine line width. Therefore, a stack technology has been proposed as another method for providing a high capacity semiconductor module.

상기와 같은 스택 기술은 스택 된 2개의 칩을 하나의 패키지 내에 내장시키는 방법과 패키징 된 2개의 단품의 패키지를 스택하는 방법이 있다. 그러나, 상기와 같이 2개의 단품의 패키지를 스택하는 방법은 전기·전자 제품의 소형화되는 추세와 더불어 그에 따른 반도체 패키지의 높이의 한계가 있다.The stack technology described above includes a method of embedding two stacked chips in one package and stacking two packaged packages. However, the method of stacking two single packages as described above has a limit of height of the semiconductor package with the trend of miniaturization of electrical and electronic products.

따라서, 하나의 패키지의 2∼3개의 반도체 칩들을 탑재시키는 스택 패키지(Stack Package) 및 멀티 칩 패키지(Multi Chip Package)에 대한 연구가 최근 들어 활발하게 진행되고 있다. Therefore, research on a stack package and a multi chip package in which two or three semiconductor chips of one package are mounted has been actively conducted in recent years.

그러나, 자세하게 도시하고 설명하지는 않았지만, 전술한 종래 기술의 경우에는, 기판 상에 반도체 칩들이 수직적으로 스택됨에 따라 반도체 칩과 기판 간을 부착시키거나, 또는, 수직적으로 스택되는 상기 각 반도체 칩 간을 부착시키는 접착층의 두께와 상기 반도체 칩 자체의 두께 마진으로 인해 전체 패키지의 두께를 증가시게 된다.However, although not shown and described in detail, in the above-described prior art, as the semiconductor chips are vertically stacked on the substrate, the semiconductor chips and the substrate are attached to each other, or between the vertically stacked semiconductor chips. The thickness of the entire package is increased due to the thickness of the adhesive layer to be attached and the thickness margin of the semiconductor chip itself.

예컨대, 상기와 같은 접착층 한 개의 두께가 약 150㎛이고, 상기 반도체 칩의 각 두께가 50㎛인 경우에 있어서, 상기와 같은 접착층 및 상기 반도체 칩을 8개 스택하여 스택 패키지를 제작할 경우, 전체 패키지의 두께는 약 1.5㎜가 되게 된다.For example, in the case where the thickness of one adhesive layer is about 150 μm and the thickness of each of the semiconductor chips is 50 μm, when the stack of eight adhesive layers and the semiconductor chips is stacked to manufacture a stack package, the entire package The thickness of will be about 1.5 mm.

이와 같이 상기와 같은 접착층 두께 및 반도체 칩 자체의 두께로 인해 전체 패키지의 두께가 증가하게 되며, 더욱이, 이러한 두께는 양산성 측면에서 패키지로 서의 가치가 없게 된다.As described above, the thickness of the entire package is increased due to the thickness of the adhesive layer and the thickness of the semiconductor chip itself, and furthermore, such thickness is not valuable as a package in terms of mass productivity.

본 발명은 용량을 향상시킴과 아울러, 전체 패키지의 두께를 감소시킨 스택 패키지를 제공한다.The present invention provides a stack package that improves capacity and reduces the thickness of the overall package.

상기 제1 및 제2반도체 칩들은 각각 동일하거나 또는 서로 상이한 종류로 이 루어진 것을 특징으로 한다.Each of the first and second semiconductor chips may be the same or different types.

본 발명은 내부에 다수의 반도체 칩 간을 스택하는 스택 패키지 형성시, 플래나 구조 및 수직적 스택 구조를 동시에 구현함으로써, 종래의 수직적 구조만을 갖는 스택 패키지보다 그의 용량을 향상시키면서도, 전체 패키지의 두께를 감소시킬 수 있다.According to the present invention, when a stack package stacking a plurality of semiconductor chips therein, the planar structure and the vertical stack structure are simultaneously implemented, thereby improving the capacity of the entire package while improving its capacity than the stack package having only the conventional vertical structure. Can be reduced.
