Abstract
A semiconductor energy detector having a region for detection and charge accumulation/transfer where a two-dimensional pixel array is formed on a surface of a semiconductor substrate on which energy rays become incident, is characterized in that the region for detection and charge accumulation/transfer comprises a plurality of transfer electrodes formed in each pixel, and an excess charge removing means arranged in correspondence with one of the transfer electrodes in each pixel.
