Abstract: 반도체 패키지의 제조방법을 제공한다. 먼저, 반도체 칩들 및 상기 반도체 칩들 사이에 위치하는 스크라이브 레인을 구비하는 반도체 기판을 제공한다. 상기 스크라이브 레인 내에 트렌치를 형성한다. 상기 트렌치 내에 광분해성 고분자를 충전한다. 상기 광분해성 고분자가 충전된 기판의 배면을 그라인딩한다. 상기 기판의 전면(front surface)에 광을 조사하여 상기 광분해성 고분자를 분해시킨다. 따라서, 반도체 기판을 백 그라인딩한 후 추가적인 절단 공정을 수행하지 않더라도 상기 반도체 칩들을 용이하게 분리할 수 있다. 그 결과, 백 그라인딩에 의해 얇아진 반도체 칩의 에지에 칩핑 또는 크랙이 발생하는 것을 막을 수 있다.

Abstract: A method for fabricating a thin semiconductor package is provided to obtain a slim semiconductor chip with high intensity, by degrading photodegradable polymers by projecting light on a surface of a semiconductor substrate for separating semiconductor chips, thereby protecting an edge of the semiconductor chip from chipping or cracks, without performing an additional sawing process. A method for fabricating a thin semiconductor package comprises the steps of: preparing a semiconductor substrate(10) having a plurality of semiconductor chips(C), and a scribe lane disposed between the semiconductor chips; forming a trench within the scribe lane; disposing a mask on the substrate for exposing the trench; filling photodegradable polymers within the trench exposed by the mask; removing the mask for exposing the front surface of the substrate; attaching a protective tape on the exposed front surface; back-grinding the back side of the substrate filled with the photodegradable polymers; attaching a mounting tape(17) onto the grinded back side; degrading the photodegradable polymers by projecting light(L) on the front surface of the substrate; and washing the substrate after projecting light.

Abstract: A semiconductor device package is provided to embody a direct access test with respect to each semiconductor chip by overcoming the unstability of a bonding wire in stacking a plurality of semiconductor chips. A substrate pad(111a,111b) is formed on one surface of a substrate(110). At least one memory chip(140,150) is stacked on the substrate, including a memory chip pad(141,151) connected to a common pin to which a common signal is applied. An interposer chip(130) is stacked on the substrate, including a connection wire connected to the memory chip pad. The common pin of each memory chip goes by way of the memory chip pad to be electrically connected to the connection wire. A logic/analog chip(120) is stacked on the substrate, including a bypass circuit part(125) which electrically interconnects or blocks the connection wire and the substrate pad. Each memory chip has a chip select pin for a direct access test. The chip select pin is electrically connected to the substrate.
