    摘要: In a method of manufacturing a floating gate of a non-volatile semiconductor memory, a pattern is formed on a substrate to have an opening that exposes a portion of the substrate. A first preliminary polysilicon layer is formed on the pattern and the exposed portion of the substrate to substantially fill the opening. A first polysilicon layer is formed by partially etching the first preliminary polysilicon layer until a first void formed in the first preliminary polysilicon layer is exposed. A second polysilicon layer is formed on the first polysilicon layer.

    摘要: In an exemplary embodiment of the invention a method of forming a gate oxide layer of a semiconductor device uses deuterium gas. The method includes introducing a semiconductor substrate, and depositing an insulating layer on the semiconductor substrate by supplying an oxidation reaction gas and a deuterium gas to the semiconductor substrate. Thus, a high quality gate oxide layer can be formed and resistance to degradation from the hot carrier effect can be improved. Further, when the method is applied to a tunnel oxide layer process of a flash memory, problems such as an increasing dispersion of the threshold voltage can be mitigated.
