Abstract:
A method for fabricating a semiconductor device, comprising the steps of:placing a semiconductor chip having contacts over a circuit substrate having interconnecting electrodes such that the semiconductor chip contacts abut against the substrate electrodes via solder bumps,heating and fusing the solder bumps to join the semiconductor chip to the substrate,placing the substrate having the semiconductor chip mounted thereon in a cavity of a mold,feeding an encapsulated resin composition in molten state and under a pressure of 10 to 100 kgf/cm.sup.2 into the mold cavity through a gate for forcibly filling a space between said substrate and said semiconductor chip with the resin composition, andcuring the resin composition for encapsulating the space with the resin composition,said encapsulating resin composition comprising (a) an epoxy resin, (b) a phenolic resin curing agent, and (c) 50 to 85% by weight based on the entire composition of a particulate inorganic filler having a maximum particle size of up to 24 .mu.m as essential components, said composition having a melt viscosity of up to 200 poises at the molding temperature.
