Abstract: PURPOSE: A method for forming a gate electrode is provided to reduce a leakage current and to increase a breakdown field. CONSTITUTION: A gate dielectric material, Ta2O5 film(22) is formed on a semiconductor substrate(21) and is thermally annealed at 400-900 deg.C. A metallic film like W, WNx and TiN is formed on the Ta2O5 film. After forming the metallic film, it is annealed at a temperature above 700 deg.C for above 30 seconds under N2 atmosphere. The damage of the Ta2O5 film generated in forming the metallic film is recovered by the annealing process and a VFB is reduced by reducing positive charge in an SiOx formed on the Ta2O5 film and on the bottom of the Ta2O5 film. And a gate electrode(23a) is formed by removing the metallic film and the Ta2O5 film selectively through a photo lithography process.

CONSTITUTION: In a discharge tube for an ozone generator comprising an internal electrode(12) to which a power source(10) is supplied, a grounding side of an external electrode(14), and dielectrics(18) which are interposed between the internal electrode(12) and the external electrode(14) so that the dielectrics(18) are spaced apart from the external electrode(14) in a certain distance, wherein the internal electrode(12) and the external electrode(14) are coaxially formed in a cylindrical structure, the discharge tube for an ozone generator is characterized in that the internal electrode(12) is formed in rod shape, a plurality of ventilating holes are formed on the external electrode(14), and the dielectrics(18) consist of pyrex glass or ceramic so that a single discharge tube(1) is formed, wherein a plurality of the single discharge tubes(1) are attached to the inner part of one dielectric pipe, a distance between the external electrode(14) and the dielectrics(18) is 0.5 to 2.0 mm, and the power source has a middle (700 Hz) or higher frequency.
