摘要: A method for forming a resist pattern, includes forming a lower layer film, forming an intermediate film on the lower layer film, forming a photoresist film containing a photoacid-generating agent on the intermediate film, exposing the photoresist film, and developing the photoresist film. The lower layer film contains at least any one of a free acid, a thermoacid-generating agent, and a photoacid-generating agent, on a substrate to be treated.
