摘要: A method for fabricating a conducting layer pattern using hard mask of which upper surface is flattened by the use ArF exposure light source. The includes steps of: forming on semiconductor substrate; first layer, second and third in order; photoresist an source order to form predetermined pattern; etching as mask; removing stacked having patterns, whereby spire-shaped removed from pattern.
