Target pattern layouts that include lower and upper target patterns are designed. Each lower target pattern is combined with a upper target pattern that at least partially overlaps a top surface thereof to form combination structures. The combination structures are divided into first and second combination structures. A first target pattern is formed from the lower target pattern in the first combination structure and a third target pattern is formed from the upper target pattern in the first combination structure. The first and third target patterns are formed in first and third lithography processes, respectively. A second target pattern is formed from the lower target pattern in the second combination structure and a fourth target pattern is formed from the upper target pattern in the second combination structure. The second and fourth target patterns are formed in second and fourth lithography processes, respectively.

A method of decomposing a design layout for a double patterning process is provided. The method includes changing, by a computing system, a design layout of a first polygon type to a design layout of a curved polygon type; coloring the design layout of the curved polygon type; generating stitching shapes for preventing acute corners in stitching areas of the colored design layout of the curved polygon type; separating the design layout including the stitching shapes for preventing the acute corners into separated design layouts of curved polygon type according to colors; and changing the separated design layouts of the curved polygon type to design layouts of a second polygon type.

A method of fabricating a semiconductor device may include: alternatively stacking dielectric layers and conductive layers on a substrate to form a stack structure, forming a first photoresist pattern on the stack structure, forming a second photoresist pattern whose thickness is reduced as the second photoresist pattern extends from the center of the stack structure towards a periphery of the stacked structure by performing a heat treatment on the first photoresist pattern, etching the stack structure through the second photoresist pattern to form a slope profile on the stack structure whose thickness is reduced as the slope profile extends from the center of the stack structure towards a periphery of the stacked structure, and forming a step-type profile on the end part of the stack structure by selectively etching the dielectric layer.

A single crystalline structure includes a first insulation interlayer pattern, a first epitaxial layer pattern, a second insulation interlayer pattern, and a second epitaxial layer pattern. The first insulation interlayer pattern includes a contact hole that exposes a single crystalline seed. The first epitaxial layer pattern fills up the contact hole. The second insulation interlayer pattern is formed on the first insulation interlayer pattern and the first epitaxial layer pattern. The second insulation interlayer pattern has a trench that partially exposes the first epitaxial layer pattern and has an end disposed over an upper surface of the first epitaxial layer pattern. The second epitaxial layer pattern fills up the trench. Thus, voids are not generated in the second epitaxial layer pattern and a semiconductor device having the single crystalline structure exhibits improved reliability.

A method of forming fine patterns in a semiconductor device through a double photo lithography process. A layer to be etched and a hard mask layer are sequentially formed on a semiconductor substrate. A first photo resist pattern is formed on the hard mask layer. A first hard mask layer pattern is formed by etching the hard mask layer using the first photo resist pattern. After the first photo resist pattern is removed, a second photo resist pattern is formed on the resultant structure. A second hard mask layer pattern is formed by etching the first hard mask layer pattern using the second photo resist pattern. The layer to be etched is then etched using the second hard mask layer pattern after the second photo resist pattern has been removed, resulting in patterns have line edges without rounding.
