Abstract
A process for fabricating an X-ray spectrometer having imaging and energy resolution of X-ray sources. The spectrometer has an array of adjoining rectangularly shaped detector cells formed in a silicon body. The walls of the cells are created by laser drilling holes completely through the silicon body and diffusing n.sup.+ phosphorous doping material therethrough. A thermally migrated aluminum electrode is formed centrally through each of the cells.
