Patent ID: 8263940

Claim:
A detector for detecting neutrons, comprising: a neutron reactive material adapted to interact with neutrons to be detected and release ionizing radiation reaction products in relation to said interactions with neutrons; a first semiconductor element, said first semiconductor element being coupled with said neutron reactive material and adapted to interact with said ionizing radiation reaction products and provide electrical charges proportional to the energy of said ionizing radiation reaction products; and electrodes arranged in connection with said first semiconductor element for providing charge collecting areas for collecting the electrical charges and to provide electrically readable signal proportional to said collected electrical charges, wherein said neutron reactive material is located on the same side of the first semiconducting element as the electrodes, and wherein said electrodes comprise a plurality of bump-pad areas and bump-bonding elements for connection to read-out electronics operative to receive said electrically readable signal, and further wherein said neutron reactive material is arranged between said bump-pad areas.
