    摘要: In a method of forming a thin layer (e.g., a charge trapping nitride layer) of a semiconductor device (e.g. a charge trapping type non-volatile memory device), the nitride layer may be formed on a first area of a substrate. A blocking layer may be formed on the nitride layer. An oxide layer may be formed on a second area of the substrate while preventing or reducing an oxidation of the nitride layer by a radical oxidation process in which oxygen radicals react with the second area of the substrate and the blocking layer in the first area of the substrate. The nitride layer may ensure sufficient charge trapping sites and may have a uniform thickness without oxidation thereof in the radical oxidation process.

    摘要: In a method of manufacturing a semiconductor device, a polysilicon layer doped with impurities is formed on a front side and a backside of a substrate. An insulation layer is formed on the substrate having the polysilicon layer to cover the polysilicon layer on the backside of the substrate. The insulation layer on the front side of the substrate is partially etched to partially expose the front side of the substrate. An oxidation process using oxygen radicals is then carried out to form an oxide layer on the exposed front side of the substrate Thus, when the oxidation process is carried out, the insulation layer prevents impurities in the polysilicon layer on the backside of the substrate from being outgassed. As a result electrical characteristics of the transistor formed on the front side of the substrate may not be deteriorated.
