  • Abstract
    A split-gate deep-trench MOSFET (DT-MOS) with its split gate self-biased to an integrated low voltage supply is proposed. Due to the split gate being biased to an approximately constant voltage, this structure has a smaller amount of gate-to-drain charge Qgd without increase in the specific on-resistance Ron, compared with the conventional DT-MOS. Numerical simulation results show that the figure of merit (FOM = Qgd ·Ron) is largely reduced, compared with that of the conventional DT-MOS.
