    摘要: There is disclosed a resist top coat composition, comprising at least a polymer that has an amino group or a sulfonamide group at a polymer end and that is represented by the following general formula (1); and a patterning process comprising: at least, a step of forming a photoresist film on a substrate; a step of forming a resist top coat on the photoresist film by using the resist top coat composition; a step of exposing the substrate; and a step of developing the substrate with a developer. There can be provided a resist top coat composition that makes it possible to provide more certainly rectangular and excellent resist patterns when a top coat is formed on a photoresist film; and a patterning process using such a composition.
