Novel thiobarbituric acid derivatives, polymer including repeating unit derived therefrom, bottom anti-reflection coating composition containing the same and process for forming resist pattern using the composition

The present invention relates to novel thiobarbituric acid derivatives, a polymer comprising a repeating unit derived from the same, a bottom anti-reflective coating (BARC) composition containing the same, and a process for forming resist patterns using the same. Specifically, the present invention relates to a BARC composition comprising thiobarbituric acid derivatives or a polymer comprising a repeating unit derived from the same, which prevents the reflection at an underlying layer in a lithographic process, and has fast dry etching rate, and thus is useful for semiconductor ultrafine patterning; and to a process for forming resist patterns using the same.COPYRIGHT KIPO 2017
