    摘要: A method of manufacturing a semiconductor device which is excellent in high-temperature high-humidity reliability without decreasing moldability and curability is provided. The method includes sealing a semiconductor element in resin using a semiconductor-sealing epoxy resin composition; and then performing a heating treatment. The semiconductor-sealing epoxy resin composition contains (A) an epoxy resin of formula (1): wherein X is a single bond, —CH2—, —S— or —O—; and R1 to R4, which may be the same as or different, are each —H or —CH3, (B) a phenolic resin, (C) an amine-based curing accelerator, and (D) an inorganic filler. The heating treatment is performed under heat treatment conditions defined by a region in which a relationship t≧3.3×10−5 exp(2871/T) is satisfied where t is heat treatment time in minutes and T is heat treatment temperature in ° C. and where 185≦T≦300.

    摘要: Copolycondensation of a hydroxyl group-containing naphthalene and xylene with an aldehyde compound gives a polyhydroxy aromatic compound. The hydroxyl group-containing naphthalene comprises at least one of naphthols and dihydroxynaphthalenes. In the polyhydroxy aromatic compound, the proportions of the naphthalene unit and xylene unit are 95 to 50:5 to 50 (mole percent), and each molecule contains 2 to 20 naphthalene units. The polyhydroxy aromatic compound is useful as an epoxy resin curing agent. Reaction of the polyhydroxy aromatic compound with an epihalohydrin gives an epoxy resin. An epoxy resin composition can be prepared from the epoxy resin and a curing agent. The epoxy resin composition suited for use as an IC encapsulant gives a cured product having a high glass transition temperature, high heat stability, high mechanical strength, and low moisture absorbing ability, hence good moisture resistance, owing to the presence of xylene in its molecular skeleton, thus cracking is avoided even during soldering treatment. The composition is therefore suitable as an IC encapsulant.

    摘要: Copolycondensation of .alpha.-naphthol and .beta.-naphthol with an aldehyde compound gives a poly-hydroxynaphthalene compound having an average molecular weight of 300 to 2,000. This compound is useful as a curing agent for epoxy resins and as a precursor of epoxy resins. Epoxy resin compositions include (1) compositions comprising an epoxy resin and the poly-hydroxynaphthalene compound as a curing agent and (2) compositions comprising an epoxy resin obtained by reacting the poly-hydroxynaphthalene compound with an epihalohydrin and a curing agent. The epoxy resin compositions of the invention are characterized in that the cured resins have a high glass transition temperature and high heat stability and high moisture resistance, scarcely allowing package cracking even in soldering treatment. Therefore the compositions are suited for use in encapsulating semiconductors.
