In recent years, semiconductor devices have been produced using a resin encapsulation method, which is more easily mass-produced and cheaper than the conventional hermetic seal method. Most of the encapsulants used for resin encapsulation are silicone-based or epoxy-based thermosetting molding materials, and epoxy-based molding materials are particularly common. Semiconductor devices encapsulated with these epoxy-based molding materials has the disadvantage that it is slightly less reliable than conventional hermetically sealed products (semiconductor products sealed with glass, metal, ceramic, etc.).

In recent resin-sealed semiconductor devices, the semiconductor elements tend to be higher density and larger than before, and the package structure of the molded product also tends to be smaller and thinner.
Even higher reliability (excellent crack resistance, moisture resistance, and high temperature operability) is required. However, when such high-density, large-sized semiconductor devices are molded against soil using conventional epoxy molding materials, cracks may occur in the device after molding, or cranks may occur in the molding resin. Sometimes. In some cases, similar cracks may occur during reliability tests (thermal shock resistance tests, moisture resistance tests, high temperature operation tests, etc.) after molding.
