An image sensor package cover with an opaque epoxy silk-screened into it. This epoxy is patterned to the appropriate size, for a particular sensor, to form an integral light shield on the cover, while simultaneously covering to the package. This masks the internal light reflections as well as the prior art methods of using a separate light shield, but eliminates a separate component and the costly labor required to assemble such a product. Such a configuration can be applied to a linear or area type image sensor.
[ What is claimed is:] [1.] An assembly for an image sensor comprising:an image sensor package having an internal cavity;an image sensor contained within the internal cavity that is electrically coupled to a plurality of connector pads within the internal cavity;a plurality of photodetectors contained on the image sensor; anda transparent cover for the image sensor package, the cover having an integrated light shield formed from an opaque material silk-screened on the cover such that there is an aperture within the light shield over at least the photodet...
