A method of producing a layer structure and a method of forming a pattern, the method of producing a layer structure including coating a first composition on a substrate that has a pattern thereon; curing the coated first composition to form a first organic layer; applying a liquid material to the first organic layer to remove a part of the first organic layer; and coating a second composition on remaining parts of the first organic layer; and curing the coated second composition on the remaining parts of the first organic layer to form a second organic layer: wherein the first composition and the second composition each independently include a solvent, and a polymer including a structural unit represented by Chemical Formula 1,*A-B*.&#x2003;&#x2003;[Chemical Formula 1]

Method of producing layer structure, and method of forming patterns

An organic layer composition includes a first compound having a thermal shrinkage ratio of about 10% to about 70%, a second compound having a smaller thermal shrinkage ratio than the first compound, and a solvent, and an organic layer obtained by curing the organic layer composition and a method of forming patterns using the organic layer composition are disclosed. A method of measuring the thermal shrinkage ratio is described in the detailed description.
