Michael W. Engel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8987705
    Abstract: Carbon nanotubes can be aligned with compatibility with semiconductor manufacturing processes, with scalability for forming smaller devices, and without performance degradation related to structural damages. A planar structure including a buried gate electrode and two embedded electrodes are formed. After forming a gate dielectric, carbon nanotubes are assembled in a solution on a surface of the gate dielectric along the direction of an alternating current (AC) electrical field generated by applying a voltage between the two embedded electrodes. A source contact electrode and a drain contact electrode are formed by depositing a conductive material on both ends of the carbon nanotubes. Each of the source and drain contact electrodes can be electrically shorted to an underlying embedded electrode to reduce parasitic capacitance.
    Type: Grant
