    摘要: Methods of fabricating a semiconductor device are provided, the methods include forming a first dielectric layer, a data storage layer, and a second dielectric layer, which are sequentially stacked, on a semiconductor substrate. A mask having a first opening exposing a first region of the second dielectric layer is formed on the second dielectric layer. A gate electrode filling at least a portion of the first opening is formed. A second opening exposing a second region of the second dielectric layer is formed by etching the mask such that the second region is spaced apart from the first region. A second dielectric pattern and a data storage pattern are formed by sequentially etching the exposed second region of the second dielectric layer and the data storage layer. The second dielectric pattern is formed to have a greater width than a lower surface of the gate electrode.

    摘要: A method of filling a gap on a substrate comprises disposing the substrate, on which the gap is formed, on a susceptor in a chamber; applying a source power to the chamber to generate plasmas into the chamber; supplying a process gas into the chamber; filling a thin film into a gap by applying a first bias power to the susceptor, an amplitude of the first bias power being periodically modulated; stopping supply of the process gas and cutting off the first bias power; and extinguish the plasmas in the chamber.
