Abstract:
A window-type semiconductor package, comprising:a substrate having an upper surface and a lower surface opposed to the upper surface, and formed with at least an opening penetrating through the upper and lower surfaces, wherein a tape attach area is defined on the upper surface of the substrate peripherally around the opening; an adhesive tape formed with an aperture corresponding in position to the opening of the substrate, and applied over the tape attach area and around the opening in a manner as to align the aperture of the adhesive tape with the opening of the substrate; at least a chip having an active surface and a non-active surface opposed to the active surface and mounted over the adhesive tape, wherein the active surface is larger than and completely covers the aperture and the opening, allowing a conductive area on the active surface of the chip to be exposed to the opening of the substrate and the aperture of the adhesive tape, and the adhesive tape is interposed between the active surface of the chip and the upper surface of the substrate such that the active surface of the chip, exclusive of the conductive area, is completely covered by the adhesive tape to be free of forming gaps between the chip and the substrate; a plurality of bonding wires formed through the opening of the substrate and the aperture of the adhesive tape, so as to electrically connect the conductive area on the active surface of the chip to the lower surface of the substrate by means of the bonding wires; a first encapsulant formed on the lower surface of the substrate for encapsulating the bonding wires and for filling the opening of the substrate and the aperture of the adhesive tape; a second encapsulant formed on the upper surface of the substrate for encapsulating the chip; and a plurality of solder balls implanted on the lower surface of the substrate at an area outside the first encapsulant.
