ため半導体封止材料として広く用いられている。(Prior Art) Conventionally, electronic components such as diodes, transistors, and integrated circuits have been sealed using thermosetting resin. This resin sealing is economically advantageous compared to hermetic sealing methods using glass, metal, or ceramic, and is therefore widely put into practical use. Thermosetting resins are used as sealing resins, and epoxy resin compositions are most commonly used. Epoxy resin compositions use curing agents such as acid anhydrides, aromatic amines, and novolak-type phenol resins. Among these, epoxy resin compositions using novolanc type phenolic resin as a curing agent have better moldability than those using other curing agents! 1 (It is widely used as a semiconductor encapsulation material because it has excellent moisture properties, is non-toxic, and is inexpensive.

形性に劣る欠点があった。However, epoxy resin compositions using a novolac type phenolic resin as a curing agent have the disadvantage that they shrink during molding and curing, applying stress to semiconductor elements, resulting in poor reliability. When a molded article using such a resin composition is subjected to a tin-based cycle test, positive ink wire opens, resin cracks, and pellet cracks occur, resulting in a loss of functionality as an electronic component. In such cases, in order to create a composition with low stress, a large amount of inorganic filler is added to lower the coefficient of thermal expansion. SO, J (5nail 0
There was a problem that thin packages such as Utline J-1 (ead package) could not be filled sufficiently. Furthermore, in the case of highly thermally conductive resins, a large amount of inorganic filler is added to increase the thermal conductivity, which has the same drawback of poor moldability.

1勿が得られるものである。(Function) The encapsulating resin composition of the present invention uses a compound having a polyoxyalkylene glycol structure and an acid anhydride, so that its mature structure is open to hardening of epoxy and grease-resistant. However, the polyoxyalkylene glycol structure tends to have low stress. As a result, a sealing resin composition 1 having high thermal conductivity, excellent molding fluidity, low stress, and good moisture resistance can be obtained.
