Claim:
1. An image sensing device comprising: an interconnect layer and a plurality of grid array contacts carried thereby; an image sensor integrated circuit (IC) carried by said interconnect layer and coupled to said plurality of grid array contacts, said image sensor IC having an image sensing surface; a transparent plate carried by said image sensor IC and aligned with the image sensing surface; and a cap carried by said interconnect layer and having an opening aligned with the image sensing surface; said cap having an upper wall spaced above said interconnect layer and said image sensor IC to define an internal cavity; said cap defining an air vent directly coupled between the internal cavity and an external atmospheric environment so that the internal cavity is freely and fluidly coupled to the external atmospheric environment and so that said image sensor IC remains exposed to the external atmospheric environment; said cap having an inner peripheral edge spaced from adjacent portions of said transparent plate to define the air vent.
