    Abstract: A photoresist composition contains: a polymer comprising a first compound and a second compound; a photoacid generator; and a solvent. The first compound has a unit structure, which includes: hydrogen or an alkyl group; and at least one of hydrogen, a hydroxyl group, an alkyl group, an heteroalkyl group, a cycloalkyl group, an heterocycloalkyl group, an aryl group, and an heteroaryl group. The second compound has a unit structure, which includes at least one of hydrogen, a hydroxyl group, an alkyl group, an heteroalkyl group, a cycloalkyl group, an heterocycloalkyl group, an aryl group, and an heteroaryl group.

    Abstract: An apparatus for planarizing a substrate may include a supporting plate, an injection mechanism and a controller. The supporting plate may be configured to receive the substrate including a coating layer formed on the substrate before a hardening process. The supporting plate may have at least one of a function for controlling a temperature of the substrate, a function for rotating the substrate and a function for vibrating the substrate. The injection mechanism may inject a gas having a set temperature and a set pressure to the coating layer of the substrate to horizontally planarize the coating layer. The controller may control a movement, a temperature and a pressure of the injection mechanism, and the temperature control, the rotation control and the vibration control of the supporting plate.
