    摘要: In methods of manufacturing semiconductor devices, a preliminary gate oxide layer is formed on a substrate. A surface treatment process is performed on the preliminary gate oxide layer that reduces a diffusion of an oxidizing agent in the preliminary gate oxide layer to form a gate oxide layer on the substrate. A preliminary gate structure is formed on the gate oxide layer. The preliminary gate structure includes a first conductive layer pattern on the gate oxide layer and a second conductive layer pattern on the first conductive layer pattern. An oxidation process is performed on the preliminary gate structure using the oxidizing agent to form an oxide layer on a sidewall of the first conductive layer pattern and on the gate oxide layer, and to round at least one edge portion of the first conductive layer pattern.

    摘要: In a method of manufacturing a semiconductor device including a polysilicon layer on which a heat treatment is performed in hydrogen atmosphere, a preliminary polysilicon layer is formed on a semiconductor substrate. Fluorine (F) impurities are implanted onto the preliminary polysilicon layer, so that the preliminary polysilicon layer is formed into a polysilicon layer. A main heat treatment is performed on the polysilicon layer, thereby preventing a void caused by the fluorine (F) in the polysilicon layer. A subsidiary heat treatment is further performed on the polysilicon layer prior to the main heat treatment, thereby activating dopants in the polysilicon layer. Electrical characteristics and performance of a semiconductor device are improved since the void is sufficiently prevented in the polysilicon layer.

    摘要: In a method for forming a gate in a semiconductor device, a first preliminary gate structure is formed on a substrate. The first preliminary gate structure includes a gate oxide layer, a polysilicon layer pattern and a tungsten layer pattern sequentially stacked on the substrate. A primary oxidation process is performed using oxygen radicals at a first temperature for adjusting a thickness of the gate oxide layer to form a second preliminary gate structure having tungsten oxide. The tungsten oxide is reduced to a tungsten material using a gas containing hydrogen to form a gate structure. The tungsten oxide may not be formed on the gate structure so that generation of the whiskers may be suppressed. Thus, a short between adjacent wirings may not be generated.
