A detector for electromagnetic radiation, pixel structure with high sensitivity using such detector and method of manufacturing such detector

(57) A summary and subject All the electric charge careers formed by radiation in the semiconductor offer the semiconductor device for electromagnetic radiation detection which are collected all over collecting junction or a domain, and is not brought together in junction or the domain of readout circuitry. Solution means Between the radiation detection volume in a semiconductor, and a domain or junction equipped with readout circuitry, It has an effective barrier, although it is small, and it does not have a barrier between the domain or junction prepared in order to collect the electric charge careers generated by radiation to a semiconductor board and this semiconductor board, or has a low barrier.
