    摘要: There is disclosed a negative resist composition wherein a base resin contains at least repeating units represented by the following general formula (1) and general formula (2) and has a weight average molecular weight of 1,000 to 10,000, and the compound containing a nitrogen atom as a basic component contains one or more kinds of amine compounds having a carboxyl group and not having a hydrogen atom covalently bonded to a base-center nitrogen atom. There can be a negative resist composition in which a bridge hardly occurs, substrate dependence is low and a pattern with a high sensitivity and a high resolution can be formed, and a patterning process using the same.
