The present invention relates to a sealing resin composition.

の点からエポキシ樹脂が最も一般的に用いられている。(Prior Art) Conventionally, methods have been used to seal electronic components such as diodes, transistors, and integrated circuits using thermosetting resins. This resin sealing is widely put into practical use because it is economically advantageous compared to hermetic sealing methods using glass, metal, or ceramic. As a sealing resin,
Thermosetting resins are used, of which epoxy resins are most commonly used because of their reliability and cost.

半導体封止材料として広く用いられている。For epoxy resins, curing agents such as acid anhydrides, aromatic amines, and novolac-type phenolic resins are used. Among these, epoxy resins using novolac type phenolic resin as a curing agent have excellent moldability and moisture resistance, are non-toxic, and are inexpensive compared to those using other curing agents, so they are used as semiconductor encapsulation materials. Widely used.
しかしながら、ノボラック型フェノール樹脂を硬化剤と

、熱膨張係数を下げて応力を下げる方法がとられるが、
その場合、充填剤を多電に混入するため成形の流動性に
劣り、ワイヤオープン等の生ずる欠点があった。However, epoxy resins using novolac-type phenolic resin as a curing agent have a drawback of being inferior in reliability with respect to moisture resistance and heat resistance, which are severe as electronic components become more dense. When molded products using such resins are subjected to hot and cold cycle tests, open bonding wires, resin cracks, and pellet cracks occur, making them unable to function as electronic components, and when moisture resistance tests are conducted, the above-mentioned problems occur. A similar phenomenon occurred, and there was also the drawback that the same function could not be achieved. In addition, in recent years, there are many insulation type packages in which the radiation fins are completely covered with sealing resin, but in this case, heat must be dissipated through the resin, so λ; 55X10-' Cal/CI -Se
c ・A rating of 'C or higher was required. However, since λ=55xlO-' cal/c+g・sec ・
In order to achieve a temperature higher than 0.degree. C., a large amount of filler must be used, which has the disadvantage of causing pinholes during molding. Furthermore, recent sealing resins have generally been formulated with low stress due to the demand for higher density semiconductors. For this reason, methods are used to reduce stress by lowering the coefficient of thermal expansion.
In this case, since the filler is mixed into the polyconductor, the fluidity of molding is poor, and there are drawbacks such as wire opening.
