    摘要: A heat-treatment apparatus includes a quartz heat-treatment tube having a vertically set axis in which a heat-treatment gas is supplied from its lower portion, and a quartz cap to be mounted on an upper opening portion of the heat-treatment tube. An opening is formed in a central portion of the cap, a quartz rod is inserted through the opening along the axis of the heat-treatment tube, and semiconductor parts to be heat-treated are held by the rod. A first exhaust duct is formed in a side surface of the heat-treatment tube at a position higher than at least the semiconductor parts held by the rod and exhausts the heat-treatment gas in the heat-treatment tube. A ring-like chamber open toward the inner surface of the cap is formed in the outer circumferential surface of the heat-treatment tube in a position close to the upper opening surface, and a second exhaust duct communicates with this chamber. The chamber communicates with the opening portion formed in the cap in the outer circumferential portion of the rod and communicates with the interior of the heat-treatment tube, thereby exhausting an external air drawn from the opening together with the heat-treatment gas in the heat-treatment tube.

    摘要: According to the present invention, when a wiring layer using copper is formed, an interlayer insulation film is formed on a semiconductor substrate having a conductive portion of an element. A contact hole, which is connected to at least the conductive portion, is formed in the interlayer insulation film. A wiring groove is formed in the surface of the interlayer insulation film including a region where the contact hole is formed. A barrier metal having a tungsten carbide film on its surface is formed on the surface of the interlayer insulation film and in the wiring groove and contact hole in contact with the conductive portion. A copper film is then formed on the barrier metal in contact with the tungsten carbide film. After that, the contact hole and wiring groove are completely filled with the copper film by heat treatment. An excess portion is removed from the copper film except in the contact hole and wiring groove thereby to form a copper buried wiring layer. Thus, the copper film is formed in contact with the tungsten carbide film and the wettability of copper to the barrier metal is improved, accordingly, the copper wiring layer can be increased in reliability.

    摘要: In a method for forming a high aspect ratio structure using copper in an ultra high-speed device, the degree of copper burying is heightened. A high aspect ratio structure, such as a fine connecting hole, is formed in a layer insulating film on a silicon substrate. Then, after a CVD-TiN film is formed to have a thickness of 10 nm on the insulating film, a copper film having a thickness of 1 .mu.m is formed. In this case, the highly pure copper film is formed by controlling film-forming conditions so as to set oxygen and sulfur concentrations in the film equal to a fixed level or lower. Thus, during its burying in the connecting hole, the surface diffusibility and fluidity of the copper film heated by means of laser irradiation are facilitated.
