    摘要: Methods and apparatus for packaging a backside illuminated (BSI) image sensor or a BSI sensor device with an application specific integrated circuit (ASIC) are disclosed. A bond pad array may be formed in a bond pad area of a BSI sensor where the bond pad array comprises a plurality of bond pads electrically interconnected, wherein each bond pad of the bond pad array is of a small size which can reduce the dishing effect of a big bond pad. The plurality of bond pads of a bond pad array may be interconnected at the same layer of the pad or at a different metal layer. The BSI sensor may be bonded to an ASIC in a face-to-face fashion where the bond pad arrays are aligned and bonded together.
