A resist lower layer film composition, wherein an etching speed is fast, thus an etching time period can be shortened to minimize a film thickness loss of a resist pattern and a deformation of the pattern during etching, therefore, a pattern can be transferred with high accuracy and an excellent pattern can be formed on a substrate is provided. The resist lower layer film composition comprising at least a polymer having a repeating unit represented by the following general formula (1).
