发明名称 Manufacturing method for wiring
摘要 In the case in which a film for a resist is formed by spin coating, there is a resist material to be wasted, and the process of edge cleaning is added as required. Further, when a thin film is formed on a substrate using a vacuum apparatus, a special apparatus or equipment to evacuate the inside of a chamber vacuum is necessary, which increases manufacturing cost. The invention is characterized by including: a step of forming conductive layers on a substrate having a dielectric surface in a selective manner with a CVD method, an evaporation method, or a sputtering method; a step of discharging a compound to form resist masks so as to come into contact with the conductive layer; a step of etching the conductive layers with plasma generating means using the resist masks under the atmospheric pressure or a pressure close to the atmospheric pressure; and a step of ashing the resist masks with the plasma generating means under the atmospheric pressure or a pressure close to the atmospheric pressure. With the above-mentioned characteristics, efficiency in use of a material is improved, and a reduction in manufacturing cost is realized.
