Title:
RADIATION SENSITIVE COMPOSITION AND RESIST PATTERN FORMING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/180049
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a radiation sensitive composition which has excellent sensitivity and LWR performance. The present invention is a radiation sensitive composition which contains a polymer that has a first structural unit having an acid-cleavable group, a first compound that produces a first acid when irradiated with radiation, and a second compound that produces a second acid when irradiated with radiation, and wherein: the first acid does not substantially dissociate the acid-cleavable group under the conditions of 110°C and one minute; and the second acid dissociates the acid-cleavable group under the conditions of 110°C and one minute. In addition, this radiation sensitive composition satisfies at least one of the condition (1) and the condition (2) described below.
(1) The polymer contains a monovalent iodine atom.
(2) This radiation sensitive composition additionally contains a third compound which is other than the first compound and the second compound, and which contains a monovalent iodine atom.
