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.

Organic layer composition and method of forming patterns

A method of producing a layer structure includes forming a first organic layer by applying a first composition including an organic compound on a substrate having a plurality of patterns, applying a solvent on the first organic layer to remove a part of the first organic layer, and applying a second composition including an organic compound on a remaining part of the first organic layer and forming a second organic layer through a curing process.

Method of producing layer structure, layer structure, and method of forming patterns

A polymer includes a structural unit represented by Chemical Formula 1 and an organic layer composition including the same. wherein in Chemical Formula 1, A is a carbon cyclic group including at least one hetero atom, B is one of groups in Group 1, where Arto Ar, Rto R, L and m are as defined in the specification and * is a linking point. When the carbon cyclic group includes at least two hetero atoms when the carbon cyclic group includes a pentagon cyclic moiety and the pentagon cyclic moiety includes a nitrogen atom (N) as a hetero atom, and the at least two hetero atoms are the same or different:
