本発明は、耐半田ストレス性に優れた半導体封止用エポ
キシ樹脂組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an epoxy resin composition for semiconductor encapsulation that has excellent solder stress resistance.
半導体関連技術は近年の軽薄短小化傾向より実装密度を
向上させる方向で進んできた。そのためにメモリーの集
積度の向上や実装方法のスルーホール実装から表面実装
への移行が進んでいる。Semiconductor-related technology has progressed in the direction of increasing packaging density due to the recent trend toward lighter, thinner, and smaller devices. To this end, the density of memory is increasing and the mounting method is shifting from through-hole mounting to surface mounting.

J、PLCCに変わってきており、応力によるパッケー
ジクランクの発生、これらのクランクによる耐湿性の低
下等の問題がある。Therefore, the puff cage has changed from the conventional DIP type to a small and thin flat package for surface mounting, SOP, SO.
J, PLCC, and there are problems such as the occurrence of package cranks due to stress and a decrease in moisture resistance due to these cranks.
特に表面実装工程でのリードの半゛田付は時でパッケー

レス性が不充分であった。In order to solve these problems, soldering requires the addition of thermoplastic oligomers (Japanese Patent Laid-Open No. 62/1999) to alleviate the thermal shock caused by soldering.
-115849) and addition of various silicone compounds (JP-A-62-115850, 62-11665)
4, 62-128162) and silicone modification (Japanese Patent Application Laid-open No. 62-136860), these methods sometimes cause cracks in the package when soldering, resulting in damage to the package. Although it has not been possible to obtain an excellent epoxy resin composition for semiconductor encapsulation, heat-resistant epoxy P4y with excellent solder stress resistance has been developed.
In order to obtain N compositions, the use of polyfunctional epoxy resins (Japanese Unexamined Patent Publication No. 168620/1983) has been considered as a resin system, but the use of polyfunctional epoxy resins increases crosslinking density and improves heat resistance. But especially between 200°C and 300'
When exposed to high temperatures such as C, the solder stress resistance was insufficient.

る。According to the present invention, it is possible to obtain an epoxy tree JIW&[I paraboloid that has heat resistance and flexibility that could not be obtained with conventional techniques, so soldering is not subject to heat stress due to rapid temperature changes during the process. It has excellent crack resistance when exposed to heat, and has good moisture resistance, making it ideal for use in sealing, covering, and insulating electronic and electrical components, especially for highly integrated devices mounted on surface-mounted puff cages. It is suitable for large-chip IC products that require high reliability.
