    Abstract: Uniform nitride film and oxynitride film are formed by low-temperature and high-speed nitriding, not dependent on nitriding time and nitriding temperature of nitriding reaction. A solid dielectric is arranged on at least one opposing plane of a pair of counter electrodes under a pressure of 300 (Torr) or more. A nitrogen gas including an oxide of 0.2% or less is introduced between the pair of counter electrodes so as to apply a magnetic field, and N2 (2nd p.s.) or N2 (H.I.R.) activated species plasma is obtained. The plasma is brought into contact with an object to be processed and the nitride film/oxynitride film is formed on the surface of the object to be processed. ® KIPO & WIPO 2007

    Abstract: A method for fabricating a flash memory device is provided to improve a breakdown voltage characteristic and a leakage current characteristic by forming an oxynitride layer by a nitride process using plasma. An oxide layer is formed on a semiconductor substrate. A nitride process using plasma is performed to transform the oxide layer into an oxynitride layer(104) wherein N2 gas or mixture gas of N2 gas and Ar gas is used. A post heat treatment is performed within 12 hours after the nitride process using plasma is performed.

    Abstract: A method for manufacturing a nonvolatile memory device is provided to compensate the edge of a tunnel oxide layer and to prevent a side and an upper portion of a floating gate from being excessively oxidized by using a nitridation and a thermal oxidation on the tunnel oxide layer. An isolation layer is formed on a substrate. The isolation layer is composed of a first portion for filling a trench of the substrate and a second portion protruded from an upper surface of the substrate. A tunnel oxide layer(140) is formed on the substrate between isolation layers. A floating gate(145) is formed on the tunnel oxide layer. The first and the second portions of the isolation layer are partially removed to expose a side of the floating gate and the tunnel oxide layer to the outside. A nitridation process is performed on the tunnel oxide layer. A thermal oxidation process is then performed on the tunnel oxide layer.
