반도체소자 밀봉용 에폭시수지 조성물Epoxy Resin Composition for Semiconductor Device Sealing

본 발명은 리드프레임 위에 유기접착제로서 접착된 고집적 반도체 소자를 온도, 습도, 빛, 열 및 충격등의 외부적 환경요인으로부터 보호하기 위하여 사용하는 반도체소자 밀봉용 에폭시 수지 조성물에 관한 것이다.The present invention relates to an epoxy resin composition for sealing a semiconductor device, which is used to protect a highly integrated semiconductor device bonded as an organic adhesive on a lead frame from external environmental factors such as temperature, humidity, light, heat and impact.

IC와 LSI패키지는 전기, 전자부품 및 세트기 소형, 박형화됨에 따라 매우 급속하게 다양화 되고 있다. 특히, 칩의 크기는 점점 커짐에도 불구하고 패키지는 점점 박형화, 소형화되고 많은 핀 수를 갖는 패키지로 변화하여 가고 있다. 실장방식도 표면실장방식으로 변화되고 있으며, 최근에는 두께 1mm 정도의 TSOP(Thin Small Out-Line Package)가 등장하여 실용화되고 있다. 이것은 향후 기억소자 분야의 주된 형태로 예상되며 이러한 패키지의 변화에 대응하여 반도체 소자 밀봉용 수지 조성물도 또한 종래의 기술보다 더 엄격한 저응력화, 고내열화 및 고내습성화가 동시에 요구되고 있다.IC and LSI packages are rapidly diversifying as they become smaller and thinner in electrical, electronic components and setters. In particular, although chips are getting larger, packages are becoming thinner, smaller, and have a larger number of pins. The mounting method is also being changed to the surface mounting method, and recently, a TSOP (Thin Small Out-Line Package) having a thickness of about 1 mm has been introduced and practically used. This is expected to be the main form in the field of memory devices in the future, and in response to such package changes, the resin composition for semiconductor element sealing is also required to be more stringent than the prior art in terms of low stress, high heat resistance and high moisture resistance.

일반적으로는 저압성형용 에폭시 수지 조성물이 이용되고 있으며, 에폭시 수지, 노블락형 페놀 수지 경화제, 이미다졸 또는 포스핀계의 경화촉진제등으로 구성된 종래 수지 조성물은 내습성이 나쁘기 때문에 알루미늄전극등의 부식으로 인해 특성이 열화거나, 고온시에 전기특성이 저하되어 누설전류가 증가함으로 인해서 반도체 소자의 기능이 떨어지는 등의 문제점이 있었다.Generally, a low pressure epoxy resin composition is used, and a conventional resin composition composed of an epoxy resin, a noblock-type phenolic resin curing agent, an imidazole, or a phosphine-based curing accelerator is poor in moisture resistance, and therefore, due to corrosion of an aluminum electrode or the like. There is a problem that the semiconductor device is degraded due to deterioration of characteristics or an increase in leakage current due to a decrease in electrical characteristics at high temperatures.

특히, 반도체 소자를 부착시킨 기기자체는 고온의 조건하에서 사용되는 경우가 많고, 그와같은 조건하에서는 더욱 신뢰성을 보장 받을 수 없기 때문에 80-150℃에서 바이어스전압을 인가하여 신뢰성을 평가하는 가속시험이 일반적으로 행해지고 있다.In particular, since the device itself with the semiconductor device attached is often used under high temperature conditions, and the reliability cannot be guaranteed under such conditions, an accelerated test for evaluating reliability by applying a bias voltage at 80-150 ° C. is required. It is usually done.

따라서, 본 발명의 목적은 고온전기 특성 및 내열성을 향상시킨 신규한 반도체 소자 밀봉용 수지 조성물을 제공하는데 있다.Accordingly, it is an object of the present invention to provide a novel semiconductor element sealing resin composition having improved high temperature electrical properties and heat resistance.
