Abstract:
A multilayer resist process pattern-forming method includes providing an inorganic film over a substrate. A protective film is provided on the inorganic film. A resist pattern is provided on the protective film. A pattern is provided on the substrate by etching that utilizes the resist pattern as a mask. A multilayer resist process inorganic film-forming composition includes a compound, an organic solvent, and a crosslinking accelerator. The compound includes a metal compound that includes a hydrolyzable group, a hydrolysate of a metal compound that includes a hydrolyzable group, a hydrolysis-condensation product of a metal compound that includes a hydrolyzable group, or a combination thereof. The compound includes at least one metal element belonging to Group 6, Group 12, or Group 13 of the Periodic Table of the Elements.
