    摘要: A pattern is formed by (1) coating a first positive resist composition onto a substrate, baking, patternwise exposing, PEB, and developing to form a first positive resist pattern including a large area feature, (2) applying a resist-modifying composition comprising a basic nitrogen-containing compound and heating to modify the first resist pattern, and (3) coating a second positive resist composition thereon, patternwise exposing, and developing to form a second resist pattern. The large area feature in the first resist pattern has a film retentivity of at least 50% after the second pattern formation.
