Description

반도체 패키지{Semiconductor package}Semiconductor Package {Semiconductor package}

본 발명은 반도체 패키지에 관한 것으로서, 보다 상세하게는, 열이나 외력에 의한 반도체 패키지의 형상 변형을 방지할 수 있는 반도체 패키지에 관한 것이다.The present invention relates to a semiconductor package, and more particularly, to a semiconductor package capable of preventing the shape deformation of the semiconductor package due to heat or external force.

오늘날 반도체 산업은 경량화, 소형화, 고속화, 다기능화, 고성능화되고 높은 신뢰성을 갖는 반도체 제품을 저렴하게 제조하는 방향으로 추진되고 있다. Today, the semiconductor industry is moving toward the manufacture of semiconductor products with light weight, miniaturization, high speed, multifunction, high performance and high reliability at low cost.

일반적인 반도체 제품은 웨이퍼 조립 공정을 거쳐 집적회로가 형성되고 절단된 반도체 칩들을 리드프레임 또는 인쇄회로기판 등과 같은 전기적 연결 매체에 부착한 후, 와이어 본딩, 몰딩, 트림/포밍 등의 공정들을 포함하는 여러 단위 공정들을 수행하는 방법을 통하여 반도체 패키지의 형태로 형성된다. A general semiconductor product is a wafer assembly process, the integrated circuit formed and cut semiconductor chips are attached to an electrical connection medium such as a lead frame or a printed circuit board, and then various processes including wire bonding, molding, trim / forming, and the like. It is formed in the form of a semiconductor package through a method of performing unit processes.

상기 반도체 패키지는 상술한 제조 과정 및 사용 과정 중 발생하는 열이나 외력에 의하여 상기 반도체 패키지의 형상 변형이 불가피하게 유발되며, 상기 반도체 패키지의 변형은 반도체 패키지를 구성하는 반도체 칩의 구성 등에도 큰 영향을 미칠뿐만 아니라 주변과의 전기적인 연결부에도 영향을 미쳐 전기적인 단락을 발생시키는 등 상기 반도체 패키지의 수명 및 신뢰성에 큰 영향을 미치게 된다. The semiconductor package is inevitably caused to deform the shape of the semiconductor package by heat or external force generated during the manufacturing process and use process, the deformation of the semiconductor package has a great influence on the configuration of the semiconductor chip constituting the semiconductor package, etc. In addition to this, it affects the electrical connection with the surroundings, thereby causing an electrical short, which greatly affects the lifetime and reliability of the semiconductor package.

상기 반도체 패키지의 변형은 상기 반도체 패키지 및 반도체 칩을 구성하는 각 물질 간의 열팽창 계수의 차이에 의해 대표적으로 발생한다. 즉, 상기 반도체 패키지를 형성하는 몰드와 기판 간의 열팽창 계수 차이 및 반도체 칩을 구성하는 절연막은 대부분 열이나 외력에 의해 쉽게 변형되는 고분자 재료로 이루어지기 때문에 이들 물질 간의 열팽창 계수 차이에 의해 상기 반도체 패키지의 변형이 발생한다.The deformation of the semiconductor package is typically caused by the difference in the coefficient of thermal expansion between the materials constituting the semiconductor package and the semiconductor chip. That is, since the difference in thermal expansion coefficient between the mold and the substrate forming the semiconductor package and the insulating film constituting the semiconductor chip are mostly made of a polymer material which is easily deformed by heat or external force, Deformation occurs.

한편, 종래에 사용되고 있는 반도체 패키지의 경우에는 상기 열이나 외력에 의해 발생하는 상기 반도체 패키지의 형상 변형에 대하여 수동적인 대응만을 진행하였다. 즉, 상기 반도체 패키지에 가해지는 열이나 외력에 대하여 상기 반도체 퍄키지가 일정 한계치 이내까지만 그 형상을 유지할 수 있도록 상기 반도체 패키지의 사이즈 등을 조절하면서 반도체 패키지를 제조하였다. On the other hand, in the case of a semiconductor package used in the related art, only passive response has been made to the shape deformation of the semiconductor package generated by the heat or external force. That is, the semiconductor package was manufactured while controlling the size of the semiconductor package and the like so that the semiconductor package could maintain its shape only within a predetermined limit with respect to heat or external force applied to the semiconductor package.

또한, 종래 반도체 패키지는 온도순환시험(Thermal cycle test), 낙하 및 벤딩 시험(Bending test)등과 같은 상기 열이나 외력 시험에 대하여 형상을 유지시키기 위하여 적절한 형태의 구조를 갖도록 제조된다. In addition, the conventional semiconductor package is manufactured to have a structure of a suitable shape in order to maintain the shape against the heat or external force test, such as the thermal cycle test, drop and bending test (Bending test).

그러나, 상기 시험을 통과하기 위해서 상기 반도체 패키지를 적절한 형태로 조합함에 따라 상기 반도체 패키지는 제작상 많은 제약 조건이 발생되고, 이로 인해, 반도체 패키지의 제조에 한계가 발생하게 되었다.However, as the semiconductor package is combined in an appropriate form to pass the test, the semiconductor package is subject to a lot of constraints in manufacturing, which causes a limitation in the manufacture of the semiconductor package.

또한, 상기 시험의 한계치를 극복하는 반도체 패키지의 구조는 이상적인 시험 조건에 대응하여 형성된 것으로서 갑작스러운 열이나 외력과 같은 충격에는 불량을 유발하게 된다. In addition, the structure of the semiconductor package that overcomes the limit of the test is formed in response to the ideal test conditions, causing a failure in the impact such as sudden heat or external force.

According to the present invention, the shape memory alloy may be disposed in the molding part of the semiconductor package to penetrate the molding part in a horizontal direction, thereby preventing deformation of the semiconductor package due to external heat or external force.

이에 따라, 반도체 패키지의 크기 및 형태의 큰 변화없이 외부에서 가해지는 열이나 외력에 대응할 수 있는 반도체 패키지를 형성할 수 있으며, 반도체 패키지의 형태 변형을 방지할 수 있음에 따라 반도체 패키지의 불량을 감소시킬 수 있고 신뢰성을 향상시킬 수 있다.

In detail, the present invention has a plurality of straight forms so as to penetrate the molding in the horizontal direction in the molding formed on the semiconductor chip constituting the semiconductor package, and the shape reverts to the shape before the shrinkage and deformation by heat and current Place the memory alloy.

따라서, 외부에서 가해지는 열이나 진동과 같은 외력에 의해 형태 변형이 발생하는 부위에 형상기억합금을 배치시킴으로써 반도체 패키지의 형태 변형을 방지할 수 있다. Therefore, the shape deformation of the semiconductor package can be prevented by disposing the shape memory alloy at a portion where shape deformation occurs due to external force such as heat or vibration applied from the outside.

이에 따라, 반도체 패키지의 크기 및 형태의 큰 변화없이 외부에서 가해지는 열이나 외력에 대응할 수 있는 반도체 패키지를 형성할 수 있으며, 반도체 패키지의 형태 변형을 방지할 수 있음에 따라 반도체 패키지의 불량을 감소시킬 수 있고 신뢰성을 향상시킬 수 있다. Accordingly, it is possible to form a semiconductor package that can cope with heat or external force applied from the outside without a great change in the size and shape of the semiconductor package, and to prevent the deformation of the semiconductor package, thereby reducing defects of the semiconductor package.

Accordingly, it is possible to form a semiconductor package that can cope with heat or external force applied from the outside without a great change in the size and shape of the semiconductor package, and to prevent the deformation of the semiconductor package, thereby reducing defects of the semiconductor package. Can improve the reliability.
