Patent ID: 7465603

Claim:
A wafer level package method for optical-electronic devices, comprising the steps of: providing a substrate, whose surfaces have a plurality of optical sensitive areas and a plurality of bonding pads, the bonding pads providing electrical communications from each optical sensitive area to the exterior; providing a transparent layer, whose surfaces have a plurality of conductive circuits, each of which corresponds a bonding pad on the substrate; connecting the substrate surfaces to the transparent layer surfaces, so that the bonding pads are connected to the conductive circuits; dividing the substrate into a plurality of chips, each contains at least one optical sensitive area and corresponding bonding pad; forming a protection layer on each of the chips and exposing part of the conductive circuit; forming a conductive film on the protection layer, so that the conductive film is connected to the exposed conductive circuit; and dicing the transparent layer to form a chip level semiconductor package unit.
