Abstract
Disclosed are an apparatus having a planarized substrate and a method of manufacturing the same. A coating layer is formed on a concave-convex substrate used for the apparatus and cured, thereby planarizing the concave-convex substrate.
Claims20
A method of manufacturing an apparatus, the method comprising:
- preparing a substrate;
- forming a coating layer comprising polyamic acid co-polymer on the substrate to planarize the substrate;
- and,
- forming a plurality of thin films on the coating layer.
