Patent ID: 6879030

Claim:
A strengthened 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; at least a chip having an active surface and a non-active surface opposed to the active surface, wherein the active surface is mounted over the opening on the upper surface of the substrate, allowing a conductive area of the active surface to be exposed to the opening; a non-conductive material applied over the chip exclusive of the active surface for encapsulating peripheral side of the chip; a plurality of bonding wires formed through the opening for electrically connecting the conductive area of the chip to the lower surface of the substrate; an upper encapsulant formed on the upper surface of the substrate for encapsulating the chip and the non-conductive material; and a lower encapsulant formed on the lower surface of the substrate for encapsulating the bonding wires and sealing the opening.
