Description
본 발명은 멀티 칩 반도체 패키지에 관한 것으로서, 더 자세하게는 반도체 칩이 탑재된 반도체 패키지 내부에 또다른 반도체 칩이 탑재된 반도체 패키지를 직각으로 세워 결합할 수 있도록 하므로 기울기를 감지함과 동시에 또 다른 다양한 전기적인 신호를 외부와 상호 전달할 수 있도록 하므로 소형화 및 집적화를 실행할수 있도록 하는 멀티 칩 반도체 패키지에 관한 것이다.The present invention relates to a multi-chip semiconductor package, and more particularly, it is possible to combine a semiconductor package mounted with another semiconductor chip at a right angle inside the semiconductor package on which the semiconductor chip is mounted so as to detect a tilt and at the same time The present invention relates to a multi-chip semiconductor package capable of carrying out miniaturization and integration since electrical signals can be transmitted to and from the outside.
최근 반도체칩의 급속한 고집적화 및 소형화 추세에 따라 전자기기나 가전제품들도 소형화되고 있고, 이러한 추세에 따라 반도체패키지의 크기도 반도체칩의 크기로 축소되고 있다. 이와 같이 반도체칩의 크기로 축소된 반도체패키지로서는 여러 종류가 있으나 대표적으로 칩싸이즈(Chip size) 반도체패키지, 마이크로 볼그리드어레이(Micro ball grid array) 반도체패키지 등이 있으며, 이중에서도 상기 마이크로 볼그리드어레이 반도체패키지는 초소형의 반도체칩에 역시 초소형의 가요성회로기판을 접착하고 봉지재로 감싼 반도체패키지로서 초소형의 전자기기나 부품 등에 많이 사용되고 있다.Recently, electronic devices and home appliances are becoming smaller due to the rapid integration and miniaturization of semiconductor chips, and the size of the semiconductor packages is being reduced to the size of the semiconductor chips. As described above, there are many kinds of semiconductor packages reduced to the size of semiconductor chips, but there are representative chip size semiconductor packages, micro ball grid array semiconductor packages, and the like. The semiconductor package is a semiconductor package that is also bonded to an ultra-small semiconductor chip and is also a semiconductor package wrapped with an encapsulant, which is widely used for microelectronic devices and components.
이와 같이 소형화 및 집적화를 실행하기 위한 종래의 기술을 첨부된 도면 도 1을 참조하여 설명하면, 전자기기나 가전제품등의 기울기를 감지할 목적으로 사용하기 위해 미세한 회로기판(2)과 리드 프레임(3)만으로 이루어져 수지봉지재(1)가 둘러 싸여 있는 메인 반도체 패키지(8)의 내부에 상하로 세워진 또 다른 부 반도체 패키지(9) 반도체 칩(6)의 전기적인 신호를 상호 전달할 수 있도록 회로기판(5)을 연결하고, 회로기판(5)의 좌우측에는 외부의 전기적인 신호가 전달할 수 있도록 리드프레임(4)이 연결되어 있다.As described above with reference to the accompanying drawings of the prior art for carrying out the miniaturization and integration, the fine circuit board 2 and the lead frame (2) for use for the purpose of detecting the inclination of electronic devices or home appliances, etc. 3) a circuit board capable of mutually transferring electrical signals of another semiconductor package 9, a semiconductor chip 6, which is made up and down, in a main semiconductor package 8 surrounded by a resin encapsulant 1 only. (5) is connected, and the lead frame 4 is connected to the left and right sides of the circuit board 5 so that an external electric signal can be transmitted.
한편, 부 반도체 패키지(9)는 내부의 반도체 칩(6)을 중심으로 아래에는 회로기판(5)이 연결되어 있으며, 상기 반도체 칩(6)의 전기적인 신호가 외부와 상호 전달될 수 있도록 와이어(7)를 매개로 좌우측 끝단의 리드프레임(4)가 연결될 수 있도록 되어 있다.On the other hand, the sub-semiconductor package 9 has a circuit board 5 connected to the bottom of the semiconductor chip 6 therein, and wires are used so that electrical signals of the semiconductor chip 6 can be transmitted to the outside. The lead frame 4 at the left and right ends can be connected via (7).
이와 같이 구성된 종래의 기술은 부 반도체 패키지(9)의 반도체 칩(6)을 직각으로 세워 몰딩하기 위해 먼저 메인 반도체 패키지(8)에 회로기판(2)를 연결하고 부 반도체 패키지(9)의 몰딩작업과 트림을 실행한 후 부 반도체 패키지(9)가 직각으로 세워진 상태에서 전체적으로 몰딩작업하는 순서를 실행하였다.In the conventional technology configured as described above, in order to mold the semiconductor chip 6 of the secondary semiconductor package 9 at right angles, the circuit board 2 is first connected to the main semiconductor package 8, and the molding of the secondary semiconductor package 9 is performed. After the work and trim were executed, the entire molding operation was executed with the sub-semiconductor package 9 standing upright.
이로 인해 종래의 기술은 반도체 칩이 단일 개수만을 부착시키 되므로 기울기를 감지하는 전기적인 신호 이외의 다양한 신호를 얻어내지 못하게 되어 집적화 및 소형화할 수 없는 등의 문제점을 가지고 있다.For this reason, the prior art has a problem in that since a single number of semiconductor chips are attached, various signals other than an electrical signal for detecting a tilt cannot be obtained, and thus, integration and miniaturization cannot be achieved.
본 발명은 이와 같은 종래의 제반 문제점을 해결하기 위기 위한 것으로서 그 목적은 반도체 칩이 탑재된 반도체 패키지 내부에 또 다른 반도체 칩이 탑재된 반도체 패키지를 직각으로 세워 결합할 수 있도록 하므로 기울기를 감지함과 동시에 또 다른 다양한 전기적인 신호를 외부와 상호 전달할 수 있도록 하므로 소형화 및 집적화를 실행할 수 있도록 하는 데 있다.The present invention is to solve such a conventional problem, the object of the present invention is to detect the inclination because it can be coupled to the semiconductor package mounted with another semiconductor chip at a right angle inside the semiconductor package on which the semiconductor chip is mounted. At the same time, it is possible to carry out other various electrical signals to the outside, so that miniaturization and integration can be executed.
