Abstract:
1. A method for packaging semiconductor devices comprising: providing a wafer having plurality of dice, each die having an imaging portion and a plurality of bonding pads; attaching an optical cover sheet having a substantially uniform thickness to the wafer; removing portions of the optical cover sheet that overlie the bonding pads to expose the bonding pads on the dice, while leaving portions of the optical cover sheet that overlie the imaging portions of the dice, thereby defining a multiplicity of isolated optical covers; dicing the wafer to provide a multiplicity of singulated dice, each singulated die having an associated optical cover; mounting a plurality of the singulated dice on a substrate; electrically connecting each of the mounted dice to a portion of the substrate; encapsulating the dice, wherein the encapsulant surrounds peripheral edges of the optical cover, but the portion of the optical covers that overlie the imaging portion of their associated die remain unobstructed; and singulating the substrate to provide a plurality of singulated semiconductor packages, wherein the removing portions of the optical cover sheet that overlie the bonding pads to expose the bonding pads on the dice is accomplished by sawing.
