본 발명은 반도체 패키지 제조 공정용 장치에 관한 것으로써, 특히 상기 반도체 패키지를 제조하는 과정 중 반도체칩의 실장을 위해 사용되는 접착부재의 커버 필름을 자동적으로 제거할 수 있도록 한 반도체칩 부착용 접착부재의 커버 필름 제거장치에 관한 것이다.The present invention relates to an apparatus for manufacturing a semiconductor package, and more particularly, to a semiconductor chip attaching adhesive member capable of automatically removing a cover film of an adhesive member used for mounting a semiconductor chip during a process of manufacturing the semiconductor package. It relates to a cover film removing device.

일반적으로 반도체 패키지라 함은 반도체칩을 외부 환경으로부터 안전하게 보호를 행하기 위해 패키징(packaging)함으로써 필요한 장소에 실장가능한 형태로 구성한 것으로써, 매우 다양한 종류의 반도체 패키지가 개발되었고, 또한 현재에도 계속하여 개발중에 있다.In general, a semiconductor package is formed in a form that can be mounted in a necessary place by packaging the semiconductor chip in order to safely protect it from the external environment. A wide variety of semiconductor packages have been developed and continue to be It is under development.

이와 같은 다양한 종류의 반도체 패키지 중 볼 그리드 어레이(BGA; Ball Grid Array) 패키지는 그 실장 면적을 대폭 축소한 형태의 반도체 패키지로써 그 구조는 도시한 도 1과 같다.Among these various types of semiconductor packages, a ball grid array (BGA) package is a semiconductor package having a greatly reduced mounting area, and the structure thereof is shown in FIG. 1.

즉, 다수의 솔더볼(30)이 융착된 회로기판(PCB)(20)의 상면에 반도체칩(10)이 실장되어 있고, 이 반도체칩(10)과 회로기판(20)과는 와이어(40)에 의해 전기적으로 연결되어 있으며, 상기 반도체칩(10) 및 와이어(40)는 에폭시 몰딩 컴파운드(Epoxy Molding Compound)와 같은 수지봉지재(50)에 의해 봉지되어 외부 환경으로부터 보호된다.That is, the semiconductor chip 10 is mounted on the upper surface of the circuit board (PCB) 20 in which the plurality of solder balls 30 are fused, and the semiconductor chip 10 and the circuit board 20 are connected to the wire 40. The semiconductor chip 10 and the wire 40 are electrically connected to each other, and the semiconductor chip 10 and the wire 40 are encapsulated by a resin encapsulant 50 such as an epoxy molding compound and protected from an external environment.

이와 같은 구조를 갖는 BGA 패키지의 각 제조 공정 중 반도체칩(10)을 회로기판(20)에 실장하는 다이 본딩(die bonding) 공정에 관해 도시한 도 2a 내지 도 2c를 참조하여 보다 구체적으로 설명하면 다음과 같다.The die bonding process of mounting the semiconductor chip 10 on the circuit board 20 during each manufacturing process of the BGA package having the above structure will be described in more detail with reference to FIGS. 2A to 2C. As follows.

일반적으로 반도체칩(10)은 비 전도성 재질로 이루어진 접착부재(60)에 의해회로기판(20)의 다이패드(21) 상에 부착된다.In general, the semiconductor chip 10 is attached on the die pad 21 of the circuit board 20 by an adhesive member 60 made of a non-conductive material.

이를 위해 접착부재(adhesive)(60)를 회로기판(20)의 다이패드(21) 상에 부착하는 공정을 먼저 수행하게 된다.To this end, a process of attaching an adhesive member 60 on the die pad 21 of the circuit board 20 is first performed.

이 때, 상기 접착부재(60)는 그 상면 및 저면이 각각 접착 가능한 양면 테이프로 이루어져 있고, 이 각 면에는 커버 필름(혹은, 간지(間紙)라고도 함)(61)(62)이 각각 부착되어 이 접착부재(60)가 불필요한 부분과의 접촉을 방지하고 있다.At this time, the adhesive member 60 is made of a double-sided tape which can be attached to the upper and lower surfaces thereof, respectively, and cover films (or also referred to as slippers) 61 and 62 are attached to the respective surfaces. This prevents contact with the unnecessary portion of the adhesive member 60.

따라서, 반도체칩(10)에 접착부재(60)를 부착시킬 경우에는 도시한 도 2a와 같이 접착부재(60)의 저면에 붙어 있는 커버 필름(61)을 제거한 후 다이패드(21)의 상면에 부착하게 된다.Therefore, in the case of attaching the adhesive member 60 to the semiconductor chip 10, the cover film 61 attached to the bottom surface of the adhesive member 60 is removed as shown in FIG. 2A, and then the upper surface of the die pad 21 is removed. Will be attached.

이와 같은 과정 후 도시한 도 2b와 같이 상기 접착부재(60)의 상면에 부착되어 있는 또 다른 커버 필름(62)을 제거한 후 도시한 도 2c와 같이 커버 필름(62)이 제거된 접착부재(60)의 상면에 반도체칩(10)을 실장시킴과 동시에 이 접착부재(60)에 열을 가하게 되면 상기 접착부재는 그 접착성을 발휘하면서 반도체칩(10)을 다이패드(21)의 상면에 고정시키게 된다.After such a process, as shown in FIG. 2B, another cover film 62 attached to the upper surface of the adhesive member 60 is removed, and then the adhesive member 60 in which the cover film 62 is removed as shown in FIG. 2C is illustrated. When the semiconductor chip 10 is mounted on the upper surface of the c) and heat is applied to the adhesive member 60, the adhesive member exhibits the adhesiveness and fixes the semiconductor chip 10 to the upper surface of the die pad 21. Let's go.

이후, 반도체칩(10)의 패드(11)와 회로기판(20)의 회로패턴(22) 간을 전기적으로 연결하는 와이어본딩 공정을 수행하게 됨과 동시에 여타 공정을 순차적으로 수행하면서 그 패키징을 수행하게 된다.Thereafter, a wire bonding process for electrically connecting the pad 11 of the semiconductor chip 10 and the circuit pattern 22 of the circuit board 20 is performed, and the packaging is performed while the other processes are performed sequentially. do.

하지만, 종래 전술한 바와 같이 회로기판(20)의 다이패드(21) 상에 반도체칩(10)을 부착하는 과정은 그 제조시간의 상승을 유발하게 된 문제점이 발생되었다.However, as described above, the process of attaching the semiconductor chip 10 on the die pad 21 of the circuit board 20 causes a problem in that the manufacturing time is increased.

즉, 접착부재(60)의 양면에 붙어있는 각 커버 필름(61)(62)을 제거하기 위한 사용자의 세심한 주의를 필요로 하였을 뿐 아니라 이 사용자가 개개의 접착부재(60)에 부착된 커버 필름(61)(62)을 제때 모두 제거하여야만 하였음에 따라 전술한 바와 같이 하나의 반도체 패키지를 제조하기 위한 제조시간이 오래 걸리게 된 것이다.That is, not only the user's careful attention to remove each cover film 61 and 62 attached to both sides of the adhesive member 60 but also the cover film to which the user is attached to the individual adhesive member 60 is applied. As all of the (61) and (62) had to be removed in a timely manner, the manufacturing time for manufacturing a single semiconductor package took longer as described above.

특히, 메트릭스(matrix) 상태로써 다수의 반도체 패키지를 한번에 제조하고자 할 때에는 전술한 바와 같은 문제점이 더욱 심화되어 이의 자동화가 절실히 요구되었다.In particular, when manufacturing a plurality of semiconductor packages in a matrix state at a time, the above-described problems are further exacerbated and its automation is urgently required.

즉, 메트릭스 상태에서는 다수의 반도체 패키지를 동시에 가공하여 그 패키징을 수행함으로써 전체적인 제조시간을 단축하고자 하였지만 다이 본딩 공정시 각 접착부재에 부착된 커버 필름을 각각 제거하기란 쉽게 이루어질 수 없었던 것이다.That is, in the matrix state, a plurality of semiconductor packages were simultaneously processed and packaging was performed to shorten the overall manufacturing time, but it was not easy to remove the cover films attached to the respective adhesive members during the die bonding process.

본 발명은 상기와 같은 종래 문제점을 해결하기 위해 안출한 것으로써, 반도체칩을 회로기판에 실장하기 위해 사용되는 접착부재의 커버 필름(間紙)를 자동적으로 연속하여 제거할 수 있도록 하는 커버 필름 제거장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above-mentioned conventional problems, remove the cover film to automatically and continuously remove the cover film of the adhesive member used to mount the semiconductor chip on the circuit board The purpose is to provide a device.
