Patent number: 9096939Abstract: An electrolysis transistor for providing high-density electrochemistry and products utilizing the same, and high-efficiency electrolysis and electrochemical processes is disclosed. The electrolysis transistor may comprise an electrolyte, one or more working electrodes for transferring charge to or from said electrolyte, and one or more gate structures for altering electrode over-voltage and modifying the barrier at the electrode-electrolyte interface, reducing the voltage necessary for electrolysis. An electrochemical or photo-electrochemical cell may incorporate one or more of these electrolysis transistors.Type: GrantFiled: May 29, 2008Date of Patent: August 4, 2015Assignee: Transphorm, Inc.Inventors: Umesh Mishra, Rakesh Lai, Likun Shen, Lee McCarthy, Primit Parikh

Patent number: 8890314Abstract: An electronic component includes a high voltage switching transistor encased in a package. The high voltage switching transistor comprises a source electrode, a gate electrode, and a drain electrode all on a first side of the high voltage switching transistor. The source electrode is electrically connected to a conducting structural portion of the package. Assemblies using the abovementioned transistor with another transistor can be formed, where the source of one transistor can be electrically connected to a conducting structural portion of a package containing the transistor and a drain of the second transistor is electrically connected to the second conductive structural portion of a package that houses the second transistor. Alternatively, the source of the second transistor is electrically isolated from its conductive structural portion, and the drain of the second transistor is electrically isolated from its conductive structural portion.Type: GrantFiled: October 25, 2013Date of Patent: November 18, 2014Assignee: Transphorm, Inc.Inventor: Yifeng Wu

Publication number: 20140273422Abstract: A diode is described with a III-N material structure, an electrically conductive channel in the III-N material structure, two terminals, wherein a first terminal is an anode adjacent to the III-N material structure and a second terminal is a cathode in ohmic contact with the electrically conductive channel, and a dielectric layer over at least a portion of the anode. The anode comprises a first metal layer adjacent to the III-N material structure, a second metal layer, and an intermediary electrically conductive structure between the first metal layer and the second metal layer. The intermediary electrically conductive structure reduces a shift in an on-voltage or reduces a shift in reverse bias current of the diode resulting from the inclusion of the dielectric layer. The diode can be a high voltage device and can have low reverse bias currents.Type: ApplicationFiled: May 28, 2014Publication date: September 18, 2014Applicant: Transphorm, Inc.Inventor: Yuvaraj Dora

Patent number: 7795642Abstract: III-nitride devices are described with recessed gates. In some embodiments, the material around the gates is formed by epitaxially depositing different III-nitride layers on a substrate and etching through at least the top two layers in the gate region. Because adjacent layers in the top three layers of the structure have different compositions, some of the layers act as etch stops to allow for precision etching. In some embodiments, a regrowth mask is used to prevent growth of material in the gate region. A gate electrode is deposited in the recess.Type: GrantFiled: April 14, 2008Date of Patent: September 14, 2010Assignee: Transphorm, Inc.Inventors: Chang Soo Suh, Ilan Ben-Yaacov
