ABSTRACT:
A wire-bondable image sensor having an integral contaminant shadowing reduction structure is described. In one aspect, an image sensor includes a substrate that has a side supporting at least one imaging area and at least one wirebonding area. Light detectors are constructed and arranged to receive light through the imaging area. Bond pads are exposed in the wirebonding area for connecting to respective bond wires. A contaminant shadowing reduction structure on the imaging area has an exposed contaminant displacement surface over the imaging area and separated from the imaging area by a distance of at least 300 μm. The contaminant shadowing reduction structure is substantially transparent to radiation within an operative wavelength range specified for the image sensor. Methods of making the above-mentioned image sensor also are described.
