A semiconductor device manufacturing process, forming a multilayer structure of a metal oxide (e.g., copper oxide) and a resist underlayer film on a stepped metal substrate reduces exposure reflectance from the substrate, thereby reducing standing waves of the resist pattern (defects caused by reflection) and provides a favorable rectangular resist pattern on the substrate. A pattern-equipped substrate manufacturing method includes: a step for performing an oxidation treatment on a substrate containing metal on a surface thereof to form a metal oxide film on the substrate surface; a step for applying a resist on the metal oxide film and conducting baking to form a resist film; a step for exposing a semiconductor substrate covered by the metal oxide film and the resist; and a step for developing the exposed resist film and conducting patterning.
