Abstract:
1. A method of forming an image sensor package, comprising: providing a first substrate with opposing first and second surfaces and a plurality of image sensors formed thereon, wherein each image sensor includes a plurality of photo detectors formed on or in the first substrate and a plurality of first contact pads formed at the first surface of the first substrate which are electrically coupled to the photo detectors; forming trenches into the first substrate first surface that extends partially through the first substrate, wherein each of the trenches is disposed between two of the plurality of image sensors; forming a plurality of conductive traces each extending from one of the first contact pads and into one of the trenches; dicing the first substrate into multiple separate image sensor assemblies along dicing lines in-between the image sensors, wherein each of the image sensor assemblies includes one of the image sensors; mounting one of the image sensor assemblies to a printed circuit board, wherein the printed circuit board includes a second substrate with opposing first and second surfaces, an aperture formed through the second substrate, one or more circuit layers, and a plurality of second contact pads electrically coupled to the one or more circuit layers, wherein the first substrate of the one image sensor assembly is at least partially disposed in the aperture; and wherein the mounting includes electrically connecting each of the plurality of conductive traces of the one image sensor assembly to one of the second contact pads.
