Latest Patents

One of his latest patents is for a heterojunction diode with low turn-on voltage. This high-speed diode is formed by a heterojunction between a layer of doped semiconductor material with a narrow bandgap energy of not more than about 0.4 eV, and a layer of oppositely doped semiconductor material with a substantially wider bandgap energy. The device operates with a lower turn-on voltage than previously attainable, despite potential lattice mismatches that can produce strain and substantial lattice dislocations in the low bandgap material. The materials selected for this invention include InAs for the narrow bandgap material, InGaAs for the wider bandgap material, and InP for the substrate.

Another significant patent involves an electrical junction device with a lightly doped buffer region. This invention allows for precise location of an electrical junction between a highly p-doped semiconductor material and a more lightly n-doped semiconductor material. The buffer region is designed to establish an electrical junction at its interface with the n-doped material, ensuring a known and repeatable emitter-base turn-on voltage when applied to heterojunction bipolar transistors.
