Abstract

A composition for manufacturing a semiconductor device includes at least one carbon-based compound that includes at least one of an alkyne group and an azide group, and a solvent. A method of manufacturing a semiconductor device includes forming a feature layer on a substrate, coating the feature layer with a composition including alkyne and azide, forming a carbon-containing layer including a triazole compound by performing a heat treatment on the coated composition, forming a photoresist film on the carbon-containing layer, forming photoresist patterns by exposing and developing the photoresist film, and patterning the carbon-containing layer and the feature layer using the photoresist patterns.
