Patent ID: 7902513

Claim:
A silicon-on-insulator (SOI) neutron detector comprising: a silicon-on-insulator structure, wherein the silicon-on-insulator structure consists of an active semiconductor layer, a buried layer consisting of one selected from the group consisting of a silicon oxide, an insulator, a silicon nitride, a metal oxide, and combinations thereof, and a handle substrate; a lateral carrier transport and collection detector structure within the active semiconductor layer of the silicon-on-insulator structure; and a neutron to high energy particle converter layer to generate energetic particles above the active semiconductor layer; wherein the lateral carrier transport and collection detector structure within the active semiconductor layer of the silicon-on-insulator structure has a high immunity to gamma ray generated carriers, wherein the lateral carrier transport and collection detector structure within the active semiconductor layer of the silicon-on-insulator structure has a fast rise time neutron detector response, wherein the lateral carrier transport and collection detector structure within the active semiconductor layer of the silicon-on-insulator structure can detect either a thermal neutron or a fast neutron; wherein leakage current in the active semiconductor layer is reduced by having both the front and back surface of the active semiconductor layer either accumulated or inverted with an inversion layer.
