Abstract
Improved corrosion resistance for direct X-ray imaging detectors is obtained by providing a pixelated, electrically conductive barrier layer between the X-ray sensitive material and the pixel electrodes. Each barrier layer can cover part or all of its corresponding pixel electrode. In cases where pixel electrodes makes contact to underlying circuitry through vertical vias, it is preferred for the barrier layers to cover the via sections of the pixel electrodes. The barrier layers for each pixel electrode can be spaced apart from each other, or they can all be included within a continuous film on top of the pixel electrodes. Such a continuous film can be pixelated by spatially modulating its properties (e.g., thickness, doping) to significantly reduce lateral conductivity from pixel to pixel.
