Preparing of silicon photomultipliers and their application

The application of avalanche photo detectors in various sectors is widely discussed in the last decade. Positive qualities are low power consumption, high efficiency of the registration of photons of impact resistance, and price range. Compact array of avalanche photodiodes are required in a number of devices of medical and scientific destination. Many matrix of silicon diodes are manufactured on a monolithic semiconductor substrate, which are used as general electrode for supplying of voltage to the device. Description of technologies of the creation of new micro pixel in avalanche photodiodes has been presented in this work. Pixel density gives a chance increases the efficiency of the registration of photons.
