Abstract
A heat-reactive resist material of the invention is characterized in that the boiling point of the fluoride of the element is 200° C. or more. By this means, it is possible to achieve the heat-reactive resist material having high resistance to dry etching using fluorocarbons to form a pattern with the deep groove depth.
