US Patent 7723787 SOI MOSFET device with reduced polysilicon loading on active area

Silicon-on-insulator (SOI) devices with reduced polysilicon loading on an active area uses at least one dielectric layer resistant to silicidation to separate at least one body contact region from source/drain regions, thus reducing gate capacitance and improving device performance. The SOI devices may be used in full depletion type transistors or partial depletion type transistors.
