  • Annular segmented MOSFET
    Publication number: 20050116295
    Abstract: An annular segment MOSFET structure has reduced drain electric fields for a given applied voltage and dimensional sizing for improved reliability from damage by reducing high energy hot carriers laterally traversing the channel by reducing the intensity of electric fields in the MOSFET structure by creating diverging electric field lines with decreased electric field strength at the drain, while enabling compact integrated layouts of multiple MOSFETs within a square area of surface silicon.
