  • Patent number: 8138266
    Abstract: A semiconductor-encapsulating resin composition includes a curing agent and a compound (A) having a plurality of glycidyl ether groups. When ion viscosity of the resin composition is measured under conditions of a measurement temperature of about 175° C. and a measurement frequency of about 100 Hz, minimum ion viscosity appears at about 5 seconds or later and within about 40 seconds from a measurement starting point. The minimum ion viscosity is at least about 4.0 and at most about 7.0. A maximum slope of the ion viscosity appears at about 10 seconds or later and within about 60 seconds from the measurement starting point. The maximum slope is at least about 2.0 and at most about 6.0.
