Abstract:
1. A manufacturing method of a semiconductor device comprising: preparing a sealing resin material, which is made of a kneaded thermosetting resin composition containing a filler, including a solid foreign matter having an acetone insoluble matter, the sealing resin material comprising particulates of the kneaded thermosetting resin composition pulverized with the solid foreign matter; setting a semiconductor chip mounted on a circuit substrate and electrically connecting to the circuit substrate in a sealing apparatus comprising a pair of compression molds; supplying the sealing resin material into the sealing apparatus in which the semiconductor chip mounted on the circuit substrate is set; heating and fluidizing the sealing resin material; pressurizing the fluidized sealing resin material while heating by the compression molds to cover the semiconductor chip by the fluidized sealing resin material; and thermosetting the fluidized sealing resin material while maintaining a pressurization to seal the semiconductor chip by the cured sealing resin material, wherein the kneaded thermosetting resin composition containing the filler is pulverized with the solid foreign matter so that a maximum diameter of the solid foreign matter is smaller than a thickness T and larger than or equal to a maximum diameter of the filler, wherein the thickness T is a thickness of the cured sealing resin material formed on the semiconductor chip.
