ABSTRACT:
A process for producing an array of solid state radiation detectors includes depositing on a substrate one or more layers of silicon-based materials and then depositing a metal layer overlying silicon-based substance. The metal layer is formed into an array of metal layer regions, and then the metal layer is used as a mask to remove exposed adjacent silicon-based substance layers thereby forming an array of silicon-based substance layers that are aligned with the array of metal layers for forming an array of photosensitive sensing devices. The process of the present invention reduces the number of microlithography steps that are used in forming an array of layered amorphous silicon photosensitive devices.
