    Date of Patent: May 12, 2015
    Assignee: STMicroelectronics International N.V.
    Inventors: Alexei Ankoudinov, Vladimir Rodov
  • Patent number: 9012954
    Abstract: An Adjustable Field Effect Rectifier uses aspects of MOSFET structure together with an adjustment pocket or region to result in a device that functions reliably and efficiently at high voltages without significant negative resistance, while also permitting fast recovery and operation at high frequency without large electromagnetic interference.

  • Patent number: 8643055
    Abstract: Semiconductor protection devices, and related methods and systems, especially devices for providing series current limiting. The device typically comprises two regenerative building blocks and/or MOSFETs connected back-to-back in series, where one of the MOSFETs/Regenerative Building Blocks has an extra voltage probe electrode that provides a regenerative signal with self-limited voltage to the other via coupling to its gate electrode.

  • Publication number: 20130328113
    Abstract: A rectifier building block has four electrodes: source, drain, gate and probe. The main current flows between the source and drain electrodes. The gate voltage controls the conductivity of a narrow channel under a MOS gate and can switch the RBB between OFF and ON states. Used in pairs, the RBB can be configured as a three terminal half-bridge rectifier which exhibits better than ideal diode performance, similar to synchronous rectifiers but without the need for control circuits. N-type and P-type pairs can be configured as a full bridge rectifier. Other combinations are possible to create a variety of devices.

  • Patent number: 8598620
    Abstract: A modified MOSFET structure comprises an integrated field effect rectifier connected between the source and drain of the MOSFET to shunt current during switching of the MOSFET. The integrated FER provides faster switching of the MOSFET due to the absence of injected carriers during switching while also decreasing the level of EMI relative to discrete solutions. The integrated structure of the MOSFET and FER can be fabricated using N-, multi-epitaxial and supertrench technologies, including 0.25 ?m technology. Self-aligned processing can be used.
