  • MOSFET with self-aligned channel edge implant and method
    Patent number: 6472274
    Abstract: A MOSFET device and method, the method involves forming the MOSFET device by selectively doping bordering channel regions in the device such that, in operation, the threshold, or turn-on, voltage is equalized across the channel. The device structure comprises a self-aligned channel edge implant region for equalizing threshold voltages in the channel edge region with threshold voltages in the channel interior region, thereby virtually eliminating sub-threshold leakage current in low voltage applications.
