Abstract:
A method of manufacturing semiconductor devices in a molding machine including an upper die and a lower die, in one of which a plurality of cavities corresponding to resin-molded parts of the semiconductor devices are matrically arranged, the method comprising the steps of:covering inner faces of said cavities and a parting face of one of said dies, which contacts a substrate of the semiconductor devices, with release film, which is easily peelable from said dies and resin for molding, said release film being fixed on the inner faces of said cavities by sucking air through air sucking holes, which are respectively opened in the inner faces of said cavities, when the inner faces of said cavities and the parting face of said die are covered with said release film; clamping the substrate with said dies; filling the resin in said cavities; and forming the semiconductor devices by cutting the molded substrate.
