Abstract
A blocked impurity band detector having a high fill factor is comprised of a radiation detecting layer and an overlying blocking layer which are interposed between a plurality of rear contact regions and a frontside common electrical contact layer. Disposed over the surface of the frontside contact layer is a layer of metalization formed as a substantially transparent grid. Radiation enters the detecting layer through the grid, contact layer, and blocking layer. Each of the rear contact regions is conductively coupled to an end of a metallic conductor, or via, which is disposed through an insulating substrate. The opposite end of each of the metallic conductors exits the back surface of the substrate and is adapted for connection to an integrated circuit readout device.
