    Abstract: The present disclosure provides a semiconductor detector. The semiconductor detector comprises: a detector crystal including a crystal body, an anode and a cathode; a field enhance electrode for applying a voltage to the detector crystal; an insulating material disposed between the field enhanced electrode and a surface of the detector crystal. The semiconductor detector further comprises a field enhanced electrode circuit board having a bottom connection layer in contact with the surface of the detector crystal and a top layer opposite to the bottom connection layer, wherein the top layer is connected to a high voltage input terminal of the semiconductor detector, and an insulating material is provided between the bottom connection layer and the detector surface of the detector crystal.
