Abstract:
1. A method for manufacturing a plurality of microelectronic imaging units, comprising: providing an imager workpiece having multiple image sensor dies, the image sensor dies having image sensors configured to detect energy over a target frequency range and corresponding lens devices positioned proximate to the image sensors, the image sensors including dark pixels; attaching at least one transmissive element to the workpiece via standoffs so that the lens devices are positioned between the corresponding image sensors and the at least one transmissive element while the image sensor dies are connected to each other via the imager workpiece, the at least one transmissive element being transmissive over at least part of the target frequency range and the standoffs being positioned to cover the dark pixels in the image sensors; and separating the image sensor dies from each other after attaching the at least one transmissive element.
