Abstract: A semiconductor photomultiplier (SPM) device is described. The SPM comprises a plurality of photosensitive elements, a first electrode arranged to provide a bias voltage to the photosensitive elements, a second electrode arranged as a biasing electrode for the photosensitive elements, a plurality of quench resistive elements each associated with a corresponding photosensitive element, a plurality of output loads each having a capacitive load operably coupled to a resisitive load in a parallel configuration between first and second nodes; each first node is common to one of the photosensitive elements and the corresponding quench element; and a third electrode coupled to the second nodes of the output loads to provide an output signal from the photosensitive elements. The outputs loads fully or partially correct an overshoot of an output signal on the third electrode.

Abstract: The present disclosure relates to a process of manufacturing a photomultiplier microcell. The process comprises providing an insulating layer over an active region; and implanting a dopant through the insulating layer to form a photosensitive diode in the active region. The insulating layer once formed is retained over the active region throughout the manufacturing process.
