Title:
METHOD FOR FORMING PATTERN, RADIATION-SENSITIVE COMPOSITION, AND CLATHRATE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2021/149432
Kind Code:
A1
Abstract:
Provided are: a method for forming a pattern using a novel pattern-forming material; a radiation-sensitive composition usable as the novel pattern-forming material; and a clathrate compound suitable for use as a component of such radiation-sensitive composition. An aspect of the present invention is a method for forming a pattern which comprises a step in which a radiation-sensitive composition comprising both a polymer having a host group and a first guest compound is used to form a coating film on a substrate, a step in which the coating film is exposed to light, and a step in which the exposed coating film is developed, wherein the host group is a monovalent group formed by removing one hydrogen atom or hydroxyl group from a cyclodextrin derivative.
