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

A monomer, an organic layer composition, an organic layer, and a method of forming a pattern, the monomer being represented by the following Chemical Formula 1: 

Monomer, organic layer composition, organic layer, and method of forming patterns

A polymer, an organic layer composition, and a method of forming patterns, the polymer including a structural unit represented by Chemical Formula 1: 

Polymer, organic layer composition, 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 polymer includes a first moiety represented by Chemical Formula 1, and a second moiety including a substituted or unsubstituted C6 to C60 cyclic group, a substituted or unsubstituted C6 to C60 hetero cyclic group, or a combination thereof: In Chemical Formula 1, X is phosphorus (P), nitrogen (N), boron (B), or P&#x2550;O, Y1 and Y2 are independently hydrogen or a moiety including at least one substituted or unsubstituted benzene ring, provided that at least one of Y1 and Y2 is the moiety including at least one substituted or unsubstituted benzene ring, Y3 is another moiety including at least one substituted or unsubstituted benzene ring, and * is a linking point.
