The phenol novolak type curing agent can be obtained by a well-known method of reacting phenol with formaldehyde.

The other curing agent is not particularly limited as long as it reacts with the epoxy resin, but a relatively less coloring agent is preferred for optical semiconductor encapsulation. Preferable examples include acid anhydrides such as hexahydrophthalic anhydride, and novolak resins obtained by a condensation reaction of cresol, xylenol, resorcin and the like with formaldehyde.

The mixing ratio of the curing agent is preferably set such that the equivalent of the curing agent is in the range of 0.5 to 1.5 with respect to 1 equivalent of the epoxy resin, and particularly preferably 0.7 to 1.0. If the equivalent of the curing agent is less than 0.7, the releasability will be poor, and if it exceeds 1.0, the moisture absorption will increase and the reliability tends to deteriorate.

In the epoxy resin composition, a curing accelerator is usually used for accelerating the curing. The curing accelerator is not particularly limited as long as it has an action of accelerating the reaction between the epoxy resin and the curing agent, but a relatively less colored one is preferred. Preferred examples include organic phosphine-based curing accelerators such as triphenylphosphine and diphenylphosphine; imidazole-based curing accelerators such as 2-methylimidazole, 2-phenyl-4-methylimidazole and 2-phenylimidazole; Examples include tertiary amine-based curing accelerators such as 8-diazabicyclo (5,4,0) undecene-7, triethanolamine and benzyldimethylamine, and organic salts such as tetraphenylphosphonium / tetraphenylborate. These may be used alone or in combination.

The mixing ratio of the curing accelerator is preferably 0.05 to 1.0% by weight based on the whole sealing resin. If the amount of the curing accelerator is less than 0.05% by weight, the gelation time tends to be slow, and the curing workability tends to be significantly reduced.
This is because curing proceeds rapidly, and as a result, heat generation may increase, causing cracks and foaming.

The epoxy resin composition according to the present invention contains a release agent. As the release agent, for example, natural carnauba-based, higher fatty acid, polyethylene-based wax and the like can be used, and they may be used alone or in combination of two or more. Specifically, carnauba wax, stearic acid, montanic acid, carboxyl group-containing polyolefin and the like are preferably used. These may be used alone or in combination. The mixing ratio of the release agent is preferably 0.05 to 1.5% by weight of the whole composition. When a fatty acid amide is used as a release agent, mold stains are less likely to occur. When the cured resin material in the sealed part absorbs moisture, the absorbed moisture expands rapidly due to the thermal shock of soldering when the electronic component is mounted on the motherboard, causing cracks to occur inside the cured resin and increasing reliability. In general, an inorganic filler is blended in the epoxy resin composition because a problem of lowering may occur. As inorganic fillers,
Although not particularly limited, fused silica, crystalline silica,
Alumina and the like can be mentioned. These may be used alone or in combination. The compounding ratio of the filler is preferably 65 to 90% by weight of the whole composition.

The epoxy resin composition of the present invention can be produced by uniformly mixing the above-mentioned components with a mixer or the like, and then kneading the mixture with a roll, a kneader or the like. The order of compounding the components is not particularly limited. More specifically, the epoxy resin composition of the present invention is, for example, a three-roll or the like after melt-mixing or melt-mixing an epoxy resin, a curing agent, a curing accelerator, a release agent, a filler, and other components. The mixture can be produced by cooling and solidifying the mixture, pulverizing the mixture, and, if necessary, compressing the mixture into tablets. When the property is liquid at room temperature, it can be produced by dissolution mixing or melt kneading. (Encapsulation of a semiconductor device) The epoxy resin composition thus obtained is prepared by transfer molding a tablet in the case of a solid using a mold, and casting, potting, printing in the case of a liquid.
