Abstract: At least one of a corner portion of the semiconductor chip, a corner portion of the sealing member, and a portion in which two neighboring gold wires are spaced at a larger distance than any other two neighboring gold wires adjacent to the two neighboring gold wires is configured such that one electrode and another electrode adjacent to it are arranged in such a way that the space between one gold wire connected to one electrode and another gold wire connected to another electrode and adjacent to one gold wire is substantially equal to the diameter of these gold wires when one gold wire has been displaced toward another gold wire due to a flow of a resin at a time of sealing with the resin.

Abstract: By removing a fraction of fine particles having a particle size of less than 2 &mgr;m from starting inorganic filler particles having a mean particle size of 10-50 mm and adding thereto particles having a mean particle size of 0.1-2 &mgr;m and a specific surface area of 3-10 m2/g (BET), there is obtained a particulate inorganic filler having a mean particle size of 5-40 &mgr;m. When a large amount of the inorganic filler is loaded in an epoxy resin composition, the composition maintains a low melt viscosity enough to mold and is effective for encapsulating a semiconductor device without causing die pad deformation and wire deformation. The encapsulated semiconductor device is highly reliable.

Abstract: In an epoxy resin composition comprising an epoxy resin, a curing agent, and at least 70% by weight of an inorganic filler, at least one of the epoxy resin and the curing agent has such a molecular weight distribution as to provide an average dispersity Mw/Mn of less than 1.6, a two-nucleus compound content of less than 8% by weight and a seven- and more-nucleus compound content of less than 32% by weight. When the composition is cured at 180.degree. C. for 90 seconds into a primary product having Tg1 and the primary product postcured at 180.degree. C. for 5 hours into a secondary product having Tg2, the relationship: (Tg2-Tg1)/Tg2<0.1 is satisfied. The composition is fast-curing and effectively moldable and cures into a reliable product without a need for postcure.

Abstract: In an epoxy resin composition comprising an epoxy resin, a curing agent, and 80-90 wt % of a particulate inorganic filler, fine particles having a particle size of less than 3 .mu.m account for 10-40 wt % of the inorganic filler, and the inorganic filler has a specific surface area of less than 2.5 m.sup.2 /g as measured by a nitrogen adsorption BET method. The inorganic filler satisfies that when a blend of a bisphenol F type liquid epoxy resin having a viscosity of 30-45 poises at 25.degree. C. as measured by Gardner-Holdt method with 75 wt % of the inorganic filler is measured for viscosity at 25.degree. C. by means of an E type viscometer, the viscosity at a shear rate of 0.6 s.sub.-1 is less than 50,000 poises and the ratio of the viscosity at a shear rate of 0.6 s.sup.-1 to the viscosity at a share rate of 10 s.sup.-1 is less than 2.5/1. The epoxy resin composition has a low melt viscosity enough to mold on semiconductor devices without die pad and wire deformation.
