  • MOSFET with integrated field effect rectifier
    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.
    Type: Grant
    Filed: April 28, 2009
    Date of Patent: December 3, 2013
    Assignee: STMicroelectronics N.V.
