Patent ID: 7169645

Claim:
A method of forming package assemblies for optically interactive electronic devices comprising: providing a wafer of semiconductor material having a plurality of optically interactive devices formed thereon, wherein each optically interactive device comprises an image sensitive area disposed on a front surface of the wafer and at least one bond pad adjacent to a peripheral edge of the image sensitive area; bonding a transparent cover to the front surface of the wafer with an adhesive material, wherein the transparent cover extends over the plurality of optically interactive devices; sectioning the transparent cover around the peripheral edge of the image sensitive area of each optically interactive device such that a portion of the transparent cover remains over the image sensitive area of each optically interactive device and the at least one bond pad of each optically interactive device is exposed; cutting the wafer to separate the plurality of optically interactive devices from one another; attaching the plurality of optically interactive devices to a first surface of an interposer; electrically connecting the at least one bond pad of each optically interactive device to at least one attachment pad of a plurality of attachment pads on the first surface of the interposer; forming a layer of encapsulant material over the first surface of the interposer to cover the plurality of optically interactive devices, wherein the portion of the transparent cover remaining over the image sensitive area of each optically interactive device is exposed through the layer of encapsulant material; and cutting the interposer and the layer of encapsulant material at locations between the plurality of optically interactive devices to form a plurality of individual package assemblies.
