Abstract
A radiation-sensitive composition includes particles including a metal oxide as a principal component, and an organic solvent. A metal atom constituting the metal oxide includes a first metal atom that is a zinc atom, a boron atom, an aluminum atom, a gallium atom, a thallium atom, a germanium atom, an antimony atom, a bismuth atom, a tellurium atom, or a combination thereof. A percentage content of the first metal atom with respect to total metal atoms in the radiation-sensitive composition is no less than 50 atomic %. A pattern-forming method includes applying the radiation-sensitive composition to form a film on a substrate, exposing the film, and developing the film exposed.
