Patent ID: 8003426

Claim:
A fabrication method for a package structure of an optical device, comprising: providing a wafer, having a plurality of chips and a plurality of first cutting lines for separating the chips, and each of the plurality of chips having an optical device and a plurality of chip connection pads; dispensing a sealant to each of the plurality of chips of the wafer, and enclosing the optical device of the chip; providing a cover substrate, having a plurality of covers and a plurality of second cutting lines for separating the covers, each of the plurality of covers is corresponding to the optical device of the chips, and each of the plurality of covers is a lens or an optical filtering plate; disposing the cover substrate over the wafer and aligning the cover substrate with the wafer, so that each of the plurality of covers the optical device of the corresponding chip; curing the sealant; cutting the wafer and the cover substrate along the first cutting lines and the second cutting lines, so as to form a plurality of pre-package structures, wherein each of the pre-package structures comprises the chip, the sealant and the cover; providing a substrate strip, having a plurality of substrates, wherein each of the plurality of substrates has a plurality of first connection pads; affixing the pre-package structures to the substrates of the substrate strip; electrically connecting the chip connection pads of the chips to the substrates by a plurality of bonding wires; molding an encapsulant over the substrates, so as to package the pre-package structures and the bonding wires; and cutting the substrates and the encapsulant, for forming the package structure of the optical device.
