(Prior Art) With the recent miniaturization of word processors, personal computers, etc., and thinning of IC1LS1 cards, semiconductor components incorporated into devices are required to be smaller and thinner than before. In order to meet this demand, methods of coating with resins such as TAB are often used to seal semiconductor elements, and epoxy resin compositions are mainly used as the resin. Furthermore, in recent years, the capacitance of devices has increased in order to improve their functionality, and as a result, the area of devices has rapidly increased. In particular, how to ensure reliability when encapsulating a semiconductor element with a size of 10 to 15 mO has become a major issue. However, in conventional liquid epoxy sealing resin compositions, the stress of the resin is large, and when a semiconductor element of 10 to 15 mlO is sealed, the thermal shock resistance and moisture resistance are insufficient.

Therefore, after dissolving the epoxy resin and other resin raw materials such as curing agent and curing catalyst in an organic solvent, a large amount of inorganic filler is added. Attempts have been made to apply resin compositions to insulating coatings for semiconductors. However, in this type of sealing resin composition, when the curing catalyst is dissolved in an organic solvent, the viscosity of the system increases and the pot life is shortened and deteriorated. In addition, viscosity becomes unstable due to volatilization of the organic solvent used, which causes deterioration in the coating performance of the sealing resin composition.
