Packaging structure and method of an image sensor module

A packaging structure of an image sensor module, comprising:

• a transparent substrate having a first patterned conductive layer;
• an image sensor integrated circuit chip having a photosensitive active area carried on said transparent substrate and being electrically connected to said first patterned conductive layer of said transparent substrate, wherein said photosensitive active area faces said transparent substrate;
• at least one passive chip having opposing first and second sides, said first side bonded to said transparent substrate and said second side opposing said transparent substrate, and said passive chip including a bond pad on said second side;
• at least one insulating build-up film over said transparent substrate, having a plurality of conductive vias and a first surface opposing said transparent substrate, wherein a first end of at least one of said conductive vias is connected with said bond pad and a first end of at least one other of said conductive vias is connected with said first patterned conductive layer, and wherein second ends of said conductive vias are exposed on said first surface;
• and
• a second patterned conductive layer formed on said first surface of said insulating build-up film,
• wherein said image sensor integrated circuit chip and said at least one passive chip are both buried in said insulating build-up film.
