  • Patent number: 6878617
    Abstract: Disclosed is a method of forming a copper wire on a semiconductor device capable of preventing the natural oxidation of copper. The method comprises the steps of: forming an insulation film pattern having vias and trenches on a semiconductor substrate; forming a copper wire by filling up the vias and the trenches with copper; successively forming a capping layer and a protective layer on the copper wire and the insulation film pattern; exposing the copper wire by selectively removing the capping layer and the protective layer; and forming an oxidation-prevention layer on the copper wire. According to the present invention, the natural oxidation of copper is avoided by selectively depositing aluminum on a copper wire pad, and therefore a dependable evaluation is possible from tests of reliability in a high temperature. Furthermore, since aluminum has a lower contact resistance compared with copper, dependable test results are obtained during tests of electrical characteristics.

  • Patent number: 6790383
    Abstract: A method of gasifying organic materials (carbonaceous compounds) such as coal, shredded waste tire or waste oil into gaseous fuel, carbon monoxide and hydrogen, and an apparatus therefore are provided. The method comprises the steps of supplying initial fuel gas and oxygen into a gasification reactor to produce water and carbon dioxide, supplying the organic materials into the reactor and reacting them with the water and carbon dioxide to produce carbon monoxide and hydrogen gas, discharging the carbon monoxide and hydrogen gas from the reactor, recycling a part of the carbon monoxide and hydrogen gas discharged from the reactor into the reactor, and reacting the carbon monoxide and hydrogen gas supplied into the reactor with oxygen to produce water and carbon dioxide. The method facilitates the control of temperature in the gasification reactor as well as produces fuel gas of high quality by increasing the concentration of hydrogen.
