    • A method of producing a semiconductor- sealing-purpose epoxy resin compound by using a kneader, the latter having a suction hole disposed downstream in a direction to feed the epoxy resin compound from a kneading region, with a supply port and a delivery port disposed upstream and downstream, respectively, in the epoxy resin compound feed direction. At the same time as the volatile gas in the kneader is discharged outside the kneader through the suction hole, the epoxy resin compound is kneaded while introducing the outside air into the kneader through the openings in the supply port and delivery port. Since discharge of the volatile gas can be efficiently effected under continuous operation conditions for the kneader, the residual amount of the volatile component in the kneaded epoxy resin composition is greatly reduced; thus, generation of voids is reduced by sealing the semiconductor device by using this epoxy resin compound.
    • 通过使用捏合机制造半导体密封用环氧树脂化合物的方法,所述捏合机具有设置在从捏合区域供给环氧树脂化合物的方向的下游的吸入孔,配置有上游侧的供给口和排出口 和下游,分别在环氧树脂化合物进料方向。 在捏合机中的挥发性气体通过抽吸孔排出到捏合机外的同时,环氧树脂化合物被捏合,同时通过供给口和输送口中的开口将外部空气引入捏合机。 由于可以在连续搅拌机的操作条件下有效地进行挥发性气体的排出,因此大大降低了混炼环氧树脂组合物中挥发成分的残留量。 因此,通过使用该环氧树脂化合物密封半导体器件来减少空隙的产生。
