A manufacturing method of a semiconductor package includes the following steps of: Providing a lead frame including a plurality of leads, each of the leads having an outer lead portion, an inner lead portion and a terminal. Forming a first insulation layer on the inner lead portions and terminals. Forming a die pad on the first insulation layer. Attaching a semiconductor die to the die pad. Forming a plurality of wires for bonding pads of the semiconductor die to corresponding outer lead portions. Finally, forming a molding compound for encapsulating the lead frame, first insulation layer, die pad, semiconductor die, and wires. Furthermore, this invention also discloses a semiconductor device manufactured by utilizing the method.

Semiconductor package and manufacturing method thereof

A packaged semi-conductor substrate includes a package encapsulant pouring area, a layout provided on the substrate, a layer of solder mask deposited on the layout, and a film provided on the solder mask. When the package encapsulant is pouted into the package encapsulant pouring area, the package encapsulant is isolated from the solder mask by the film. An adhering force between the film and the package encapsulant is greater than an adhering force between the film and the mask such that the film is degated along with the package encapsulant in the pouring channel during a degating procedure of the pouring channel after a pouring procedure of the package encapsulant. Thus, the film and the package encapsulant are not residual on the substrate.

Packaged semiconductor substrate

A semiconductor packaging device includes a printed circuit board substrate, a mold gate formed on a periphery of the printed circuit board substrate through which a package encapsulant is poured to enclose electric elements mounted on a side of the printed circuit board, and a layer of non-metallic material covered on the side of the printed circuit board substrate in the mold gate area. The package encapsulant, after hardened, is bonded with the layer of non-metallic material, and the bonded package encapsulant/the layer of non-metallic material is degatable from the mold gate.
