Abstract
Apparatus and method for fabricating a backside illuminated photodiode array is described which does not use epoxy, and therefore has better transmission characteristics. The method uses indium or other coldweldable metal to fasten the detectors to the transmissive substrate. Because the indium is opaque in the waveband of detector sensitivity, it also forms an optical mask for each detector element.
