FILM-FORMING COMPOSITION AND ION IMPLANTATION METHOD

摘要

There is provided an ion implantation method, a composition for forming an ion implantation film and a resist underlayer film-forming composition. An ion implantation method including the steps of: forming a film by applying a film-forming composition containing a compound including an element in group 13, group 14, group 15, or group 16 and an organic solvent onto a substrate and baking the film-forming composition; and implanting impurity ions into the substrate from above through the film and introducing the element in group 13, group 14, group 15, or group 16 in the film into the substrate. The film-forming composition is a film-forming composition for ion implantation containing a compound including an element in group 13, group 14, group 15, or group 16, and an organic solvent. In addition, the underlayer film-forming composition contains a compound having at least two borate ester groups.
