A molding apparatus for molding semiconductor components includes a pair of opposing mold chases having mating mold cavities. The mold cavities are configured to retain polymer release films and also includes a movable pot having a reservoir for retaining a preform of molding compound, and a plunger for moving the molding compound into the mold cavities. The movable pot is mounted for axial movement within a chamfered opening in one of the mold chases. The movable pot is configured to clamp onto release films to prevent wrinkling of the release films, and seepage of the molding compound under the release films. A system for molding semiconductor components includes the molding apparatus, a pot drive mechanism for moving the movable pot, a plunger drive mechanism for moving the plunger, and a clamping mechanism for clamping the mold chases together.

1. A molding apparatus for molding semiconductor components comprising:a mold chase comprising a surface and a plurality of mold cavities proximate to the surface configured to retain a release film and to form molded portions on the components; and a movable pot and a plunger configured to inject a molding compound into the mold cavities, the pot mounted for axial movement relative to the mold chase and comprising a clamping surface, the pot movable from an open position in which the clamping surface is spaced from the surface of the mold chase, to a closed position in which the clamping surface clamps the release film to the surface of the mold chase.
