본 발명은 3차원 적층 패키지의 제조방법에 관한 것으로, 특히 패키지를 수지봉지재통을 이용하여 만들기 때문에 와이어 본딩(WIRE BONDING)공정이 삭제되고, 하나의 수지봉지재통안에 칩단위 그대로 여러개의 칩을 넣을 수 있기 때문에 디바이스 용량 확장 및 초박형 패키지를 실현시킬 수 있을 뿐만 아니라 원가절감 및 생산성 향상에 기여하도록 한 3차원 적층 패키지의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a three-dimensional laminated package, and in particular, since the package is made by using a resin encapsulation container, a wire bonding process is eliminated, and a plurality of chips as chips are stored in a single resin encapsulation container. The present invention relates to a method for manufacturing a three-dimensional stacked package, which can not only realize device capacity expansion and ultra-thin package, but also contribute to cost reduction and productivity.

종래의 기술에 의한 패키지의 적층방법은 도 1 및 도 2에 도시한 바와 같다.The stacking method of the package according to the prior art is as shown in Figs.

도 1a는 일반적인 적층 시엘피(COLUMN LEAD PACKAGE)(10)를 도시한 것이며, 도 1b내지 도 1f는 제조공정을 도시한 것이다.FIG. 1A illustrates a typical COLUMN LEAD PACKAGE 10, and FIGS. 1B-1F illustrate a manufacturing process.

도 1b와 같이 칼럼 타입 서브스트레이트(COLUMN TYPE SUBSTRATE)(1)를 제작하여, 도 1c와 같이 그라인딩(GRINDING) 한 후, 도 1d와 같이 내부에 칩(2)을 접착시키고, 도 1e와 같이 와이어 본드 후, 도 1f와 같이 에폭시 수지(3)로 몰딩(MOLDING)을 하고, 이를 서브스트레이트의 리드(4)를 연결하여 도 2와 같이 3층으로 적층시킨다.A column type substrate 1 is fabricated as shown in FIG. 1B, and after grinding as shown in FIG. 1C, the chip 2 is adhered to the inside as shown in FIG. 1D, and the wire is as shown in FIG. 1E. After bonding, molding is performed with an epoxy resin 3 as shown in FIG. 1F, and the leads 4 of the substrate are connected to each other and stacked in three layers as shown in FIG. 2.

도면중 미설명 부호 5는 전기절연체를 나타낸다.In the drawings, reference numeral 5 denotes an electrical insulator.

종래의 기술에 의한 패키지의 적층구조는 서브스트레이트(1)에 그라인딩을 해야만하는 번거로움이 있고, 또한 다이본딩 후 와이어 본딩 및 몰드를 해야 하기 때문에 공정수가 늘어나며, 적층패키지(20)의 크기도 커지게 되는 문제점이 있는 바, 본 발명의 목적은 상기와 같은 문제점을 고려하여 안출한 것으로, 패키지를 수지봉지재통을 이용하여 만들기 때문에 외이어 본딩(WIRE BONDING)공정이 삭제되고, 하나의 수지봉지재통안에 칩단위 그대로 여러개의 칩을 넣을 수 있기 때문에 디바이스용량 확장 및 초박형 패키지를 실현시킬 수 있을 뿐만 아니라 원가절감 및 생산성 향상에 기여하도록 한 3차원 적층 패키지의 제조방법을 제공함에 있다.The stacking structure of the package according to the prior art has the inconvenience of having to grind to the substrate 1, and also increases the number of steps due to wire bonding and mold after die bonding, and also increases the size of the stacking package 20. The problem is that the object of the present invention is devised in consideration of the above problems, and because the package is made by using a resin bag container, the wire bonding process is eliminated, and one resin bag material is removed. Since multiple chips can be placed in the barrel as it is, the present invention provides a method of manufacturing a three-dimensional stacked package that not only enables device capacity expansion and ultra-thin package, but also contributes to cost reduction and productivity improvement.

A chip unit forming step of forming a 30, a resin encapsulation container forming step of forming a resin encapsulation container 40 formed therein so as to accommodate the chip unit, and transmitting an electrical signal to an inner surface of the resin encapsulation container. In order to form an electrical signal board 41 in the longitudinal direction in order to cut, the resin encapsulation container is cut to a certain size, and then the chip unit is laminated in the resin encapsulation container in accordance with the electrical signal band in order. .

상기 전기신호대(41)형성단계는 수지봉지재통(40)의 내면에 길이방향으로 신호전달 홈을 형성한 후, 상기 신호전달 홈에 금속용융액을 흘려서 굳도록 하거나, 상기 신호전달홈에 금속판을 씌우도록 한다.In the forming of the electrical signal board 41, after forming a signal transmission groove in the longitudinal direction on the inner surface of the resin encapsulation container 40, a metal melt is poured into the signal transmission groove to solidify, or the metal plate is covered with the signal transmission groove. To do that.

상기 금속용융액 및 금속판은 구리나 알루미늄 금속으로 한다.The metal melt and the metal plate are made of copper or aluminum metal.

상기 적층단계는 커팅한 수지봉지재통(40)의 하면을 아래덮개(50)로 봉한 후, 칩단위(30)를 수지봉지재통내에 적충하여 윗덮개(60)를 덮도록 함으로 완료한다.The laminating step is completed by sealing the lower surface of the cut resin encapsulation container 40 with the lower cover 50, and then filling the chip unit 30 in the resin encapsulation container so as to cover the upper cover 60.

도 3은 칩위에 전기적인 신호를 연결해 줄 수 있는 테입인 전기 신호판(32)는 범프로 압착하여 붙인 후 그위에 절연체(33)를 붙여서 전기적 신호체를 만들 수 있는 하나의 칩단위(30)를 나타낸 그림이다. 전기 신호판(32)은 기존의리드 프레임역활을 하는 것으로 절연체이며, 사방으로 돌출된 전기신호선(32a)을 구비한다.3 is an electrical signal plate 32 that is a tape that can connect an electrical signal on a chip is pressed into a bump and then attached to the insulator 33 on one chip unit 30 to make an electrical signal. The figure shows. The electric signal board 32 serves as a conventional lead frame, is an insulator, and has an electric signal line 32a projecting in all directions.

도 5는 수지봉지재를 이용하여 내부가 뚫린 사각 기둥 모양의 통(40)을 만들고, 내부에 전기적인 신호를 전달해 줄 수 있게 하기 위해 신호전달홈을 파서 구리나 알루미늄 금속을 넣는 것이다.Figure 5 is to create a rectangular columnar cylinder 40, the interior of the perforated using a resin encapsulation material, to insert a copper or aluminum metal by digging a signal transmission groove to be able to deliver an electrical signal therein.

구리나 알루미늄 금속을 넣는 방법으로는 먼저 통(40)을 만들고 내부에 신호전달홈을 딴후 구리나 알루미늄금속을 액체상태에서 흘려서 굳히는 방법과, 구리나 알루미늄 금속의 판을 상기 신호전달홈에 씌우는 방법이 있다.As a method of inserting copper or aluminum metal, first, a barrel 40 is formed and a signal transmission groove is formed therein, and then copper or aluminum metal is flowed and solidified in a liquid state, and a plate of copper or aluminum metal is covered with the signal transmission groove. There is this.

칩단위(30)를 넣을때와 칩단위를 넣은 후 쓰일 상하덮개(50)(60)는 모두 절연체로 만들어 진다.The upper and lower covers 50 and 60 to be used when inserting the chip unit 30 and after the chip unit are both made of an insulator.

수지봉지재통의 밑면 구조는 피시비(PCB)(70)에 실장할 때를 고려하여 수지봉지재통(40)의 밑면을 덮어버리면 안된다.The bottom structure of the resin encapsulation container should not cover the bottom surface of the resin encapsulation container 40 in consideration of the time when it is mounted on the PCB 70.

그래서 전기신호대(41)를 덮지않고 수지봉지재통의 밑면을 막을 수 있도록 수지봉지재통의 밑면 4각 모서리에 홈(42)을 판 후 아래덮개(50)로 압착하여 봉해버린다.Therefore, the grooves 42 are formed at four corners of the bottom surface of the resin encapsulation container so that the bottom of the resin encapsulation container is not covered without covering the electrical signal board 41, and then, the bottom cover 50 is compressed and sealed.

전체 공정을 도면을 참고로 설명하면, 도 10과 같이 만들어진 수지봉지재통(40)으로부터 필요로 하는 크기 만큼 커팅한 후, 도 11과 같이 아래덮개(50)를 덮고, 도 12와 같이 칩단위(30)를 하나씩 넣고, 도 13과 같이 윗덮개(60)를 덮으면 모든 공정이 끝나게 된다.Referring to the entire process with reference to the drawings, after cutting to the required size from the resin encapsulation container 40 made as shown in Figure 10, covering the bottom cover 50 as shown in Figure 11, as shown in Figure 12 Put 30) one by one, and cover the top cover 60 as shown in Figure 13 is finished all the process.

이때 수지봉지재통(40)의 밑면은 전기 신호대(41)로 인해 홈이 남아 있는데 여기에 솔더 볼(SOLDER BALL)(44)을 장착하여 피시비(PCB)기판(70)에 실장한다.In this case, the bottom surface of the resin encapsulation container 40 has a groove left due to the electrical signal board 41, and is mounted on the PCB 70 by mounting a solder ball 44 thereon.
