A double pattern is formed by coating a first positive resist composition onto a substrate, patternwise exposure to radiation, and development with alkaline developer to form a first resist pattern; applying heat and/or radiation to render the first resist pattern insoluble in a second solvent and in a second developer; coating a second resist composition on the first resist pattern, patternwise exposure to radiation, and development with second developer to form a second resist pattern. The resin in the first resist composition comprises recurring units of formula (1) wherein R1 is H, CH3 or CF3, m=1 or 2, n=0 or 1.
