  • Abstract
    A new silicon-on-insulator (SOI) power MOSFET structure is proposed, in which buried oxide step structure (BOSS) is replaced by a buried oxide double step (BODS). Numerical simulations are performed to demonstrate that higher breakdown voltages are obtained resulting from a higher electric-field peak introduced near the BODS, and higher impurity concentration is depleted due to thin-film SOI than that in the conventional SOI and BOSS structure.
