Abstract

A pattern-forming method includes applying a radiation-sensitive composition on a substrate to provide a film on the substrate. The film is exposed. The film exposed is developed. The radiation-sensitive composition includes a metal-containing component that is a metal compound having a hydrolyzable group, a hydrolysis product of the metal compound having a hydrolyzable group, a hydrolytic condensation product of the metal compound having a hydrolyzable group, or a combination thereof. A content of a transition metal atom in the metal-containing component with respect to total metal atoms in the metal-containing component is no less than 50 atomic %.
