    摘要: A method of forming a fin field effect transistor on a semiconductor substrate includes forming a fin-shaped active region vertically protruding from the substrate. An oxide layer is formed on a top surface and opposing sidewalls of the fin-shaped active region. An oxidation barrier layer is formed on the opposing sidewalls of the fin-shaped active region and is planarized to a height no greater than about a height of the oxide layer to form a fin structure. The fin structure is oxidized to form a capping oxide layer on the top surface of the fin-shaped active region and to form at least one curved sidewall portion proximate the top surface of the fin-shaped active region. The oxidation barrier layer has a height sufficient to reduce oxidation on the sidewalls of the fin-shaped active region about halfway between the top surface and a base of the fin-shaped active region. Related devices are also discussed.

    摘要: A method for performing an erase operation in a memory cell. A first voltage and a second voltage are applied to the source and drain regions, respectively, for a predetermined erase time; and the first and second voltages are switched with each other between the source and drain regions at least one time for the erase time. Thereby, hole is easily injected to the source and drain regions and a channel lateral surface, and a uniform and high-speed erase operation is archived.

    摘要: A method is provided for driving a nonvolatile memory device. The method includes selecting first write drivers based on a predetermined current, performing a first program operation on resistive memory cells corresponding to the first write drivers, verifying whether the resistive memory cells have passed or failed in the first program operation and sorting information regarding failed bit memory cells that failed in the first program operation, selecting second write drivers based on the sorted failed bit memory cell information, and performing a second program operation on resistive memory cells corresponding to the second write drivers.
