    Abstract: A pattern-forming method comprises: forming a resist underlayer film on an upper face side of a substrate; forming a silicon-containing film on an upper face side of the resist underlayer film; and removing the silicon-containing film with a basic aqueous solution. The pattern-forming method does not include, after the forming of the silicon-containing film and before the removing of the silicon-containing film, treating the silicon-containing film with a treatment liquid comprising an acid or a fluorine compound. The silicon-containing film is preferably formed a hydrolytic condensation product of a composition containing a compound represented by formula (1) in an amount of no less than 60 mol % with respect to total silicon compounds. X represents a halogen atom or —OR2, and R2 represents a monovalent organic group. SiX4  (1)
