Abstract:
1. A method of manufacturing a neutron detector, the method comprising: forming a first wafer by at least forming an oxide layer on a substrate, forming an active semiconductor layer on the oxide layer, and forming an interconnect layer on the active semiconductor layer; forming at least one electrically conductive pathway extending from the interconnect layer through the active semiconductor layer and the oxide layer; forming a circuit transfer bond between the interconnect layer of the first wafer and a second wafer; after forming the circuit transfer bond, removing the substrate of the first wafer; after removing the substrate of the first wafer, depositing a bond pad on the oxide layer of the first wafer, the bond pad being electrically connected to the electrically conductive pathway; after removing the substrate of the first wafer, depositing a barrier layer on the oxide layer of the first wafer; and after depositing the barrier layer, depositing a neutron conversion layer on the barrier layer.
