Abstract

Official abstract text for this publication.

Provided by the present invention is a method including: (1) forming a resist underlayer film on the upper face side of a substrate to be processed using a composition for forming a resist underlayer film, the composition containing (A) a compound having a group represented by the following formula (1); (2) forming a resist coating film by applying a resist composition on the resist underlayer film; (3) exposing the resist coating film by selectively irradiating the resist coating film with a radiation; (4) forming a resist pattern by developing the exposed resist coating film; and (5) forming a predetermined pattern on the substrate to be processed by sequentially dry etching the resist underlayer film and the substrate using the resist pattern as a mask.
