A novel concave-structure MOSFET named a double lightly doped drain concave (DLC) structure was developed for sub-half-micron MOSFETs which can operate at a 5-V supply voltage. This structure has an impurity profile of n+-n--p--p along the side wall of the groove. It has been shown that the DLC MOSFET has excellent characteristics, such as (1)high drain sustaining voltage, (2)a reduced short-channel effect, (3)high current drivability, and (4)high reliability. The high current drivability provides high-speed switching.
