Abstract: The present invention description relates to a technology for calibrating an assembly error in a laser range finder, and more specifically, to a software technology for calibrating an assembly error between a laser component and an optical component. According to one aspect of the proposed invention, in order to calibrate a difference between a position of a center of a captured image and a position of a laser point due to an assembly error, the laser point is positioned at a center of a preview screen image output on a display of a laser range finder.

Abstract: Provided are a hardmask composition including a polymer including a structural unit represented by Chemical Formula 1 and a structural unit represented by Chemical Formula 2, and a solvent, a hardmask layer manufactured from the hardmask composition, and a method of forming patterns from the hardmask composition, wherein the definitions of Chemical Formula 1 and Chemical Formula 2 are as described in the specification.

Abstract: 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.
