Abstract
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.
