Abstract:
Packaged photosensor ICs are made by fabricating an integrated circuit (IC) with multiple bondpads; forming vias from IC backside through semiconductor to expose a first layer metal; depositing conductive metal plugs in the vias; depositing interconnect metal; depositing solder-mask dielectric over the interconnect metal and openings therethrough; forming solder bumps on interconnect metal at the openings in the solder-mask dielectric; and bonding the solder bumps to conductors of a package. The photosensor IC has a substrate; multiple metal layers separated by dielectric layers formed on a first surface of the substrate into which transistors are formed; multiple bondpad structures formed of at least a first metal layer of the metal layers; vias with metal plugs formed through a dielectric over a second surface of the semiconductor substrate, interconnect metal on the dielectric forming connection shapes, and shapes of the interconnect layer coupled to each conductive plug and to solder bumps.

Claim (Index 1):
A method of forming a packaged photosensor array comprising:\n fabricating a first integrated circuit having a plurality of bondpads; forming vias through a semiconductor of the first integrated circuit to expose a first layer metal of the plurality of the plurality of bondpads; depositing conductive metal plugs in the vias; after depositing the conductive metal plugs in the vias, depositing and masking an interconnect metal coupled to the conductive metal plugs; depositing a solder-mask dielectric over the interconnect metal and forming openings therethrough; forming solder bumps attached to the interconnect metal at the openings in the solder-mask dielectric; and bonding the solder bumps to conductors of an integrated circuit package.
