Abstract
A radiation detector which senses two wave bands and a process for making this detector. A first substrate includes a first photodetection element sensitive to a first wave band. A second substrate contains a second photodetection element which is sensitive to a second wave band. The second substrate is transparent to at least the first wave band. The two photodetection elements are positioned facing each other. The substrates are interconnected by conductive spheres.
