2. Description of the Related Art In a thin IC card module or the like, a semiconductor bare chip is directly sealed with a liquid epoxy resin. That is, after bonding the semiconductor bare chip on the insulating substrate and wire bonding with a gold wire or the like,
A predetermined dam frame is provided, and epoxy resin is poured into the dam frame for sealing. On the other hand, when the product thickness is relatively unrestricted, the bare chip is potted with a liquid epoxy resin having a large thixotropy and sealed without providing a dam frame. Epoxy resin for bear chip encapsulation is required to have insulating properties, heat resistance, moisture resistance, etc., low linear expansion coefficient and low impurity ion concentration in order to reduce warpage of the substrate. is there. At present, two-part or one-part epoxy resins are used, but the two-part type has poor workability, and the one-part type has a drawback that it cannot be cured at low temperature because it lengthens the stock life. there were.
