摘要:
A wafer-level camera sensor package includes a semiconductor substrate with an optical sensor on a front surface. Through-silicon-vias (TSV) extend through the substrate and provide I/O contact with the sensor from the back side of the substrate. A glass cover is positioned over the front surface, and the cover and substrate are embedded in a molding compound layer (MCL), the front surface of the MCL lying coplanar with the front of the cover, and the back surface lying coplanar with the back of the substrate. Surface-mount devices, electromagnetic shielding, and through-wafer-connectors can be embedded in the MCL. A redistribution layer on the back surface of the MCL includes bottom contact pads for mounting the package, and conductive traces interconnecting the contact pads, TSVs, surface-mount devices, shielding, and through-wafer-connectors. Anisotropic conductive adhesive is positioned on the front of the MCL for physically and electrically attaching a lens array.
