[Technical backstory of the invention and its problems] Conventionally, thermosetting resins have been used to stop electronic components such as diodes, transistors, and integrated circuits. This resin sealing is economically advantageous compared to the hermebook sealing method using glass, metal, or ceramic, and is therefore widely put into practical use. Among thermosetting resin compositions, epoxy resin compositions are most commonly used as sealing resin compositions in terms of reliability and cost.

This epoxy resin composition uses a curing agent such as an acid anhydride, an aromatic amine, or a novolac type phenol resin. Among these curing agents, epoxy resin compositions that use novolac type phenolic resins have excellent moldability and moisture resistance, are non-toxic, and are non-toxic compared to those using other curing agents.
Since it is inexpensive, it is widely used as a resin material for semiconductor encapsulation.

However, an epoxy resin composition using a novolak type phenol resin as a curing agent has the disadvantage that it shrinks when molded and cured Ik, and stress is applied to the element, resulting in poor reliability. However, when a wet/cold cycle test is performed on a molded product using such a resin composition, bonding wire cracks, resin cracks, and pellet cracks occur, and the function as an electronic component is impaired. The drawback was that it disappeared.
