    Abstract: A semiconductor device is provided as follows. Active fins protrude from a substrate, extending in a first direction. A first device isolation layer is disposed at a first side of the active fins. A second device isolation layer is disposed at a second side of the active fins. A top surface of the second device isolation layer is higher than a top surface of the first device isolation layer and the second side is opposite to the first side. A normal gate extends across the active fins in a second direction crossing the first direction. A first dummy gate extends across the active fins and the first device isolation layer in the second direction. A second dummy gate extends across the second device isolation layer in the second direction.

    Abstract: Semiconductor devices are provided including a first fin-shaped pattern having first and second sidewalls facing one another and a field insulating film contacting at least a portion of the first fin-shaped pattern. The first fin-shaped pattern includes a lower portion of the first fin-shaped pattern contacting the field insulating film; an upper portion of the first fin-shaped pattern not contacting the field insulating film; a first boundary between the lower portion of the first fin-shaped pattern and the upper portion of the first fin-shaped pattern; and a first fin center line perpendicular to the first boundary and meeting the top of the upper portion of the first fin-shaped pattern. The first sidewall of the upper portion of the first fin-shaped pattern and the second sidewall of the upper portion of the first fin-shaped pattern are asymmetric with respect to the first fin center line.

    Abstract: A semiconductor device, including first and second fin patterns separated by a first trench; a gate electrode intersecting the first and second fin patterns; and a contact on at least one side of the gate electrode, the contact contacting the first fin pattern, the contact having a bottom surface that does not contact the second fin pattern, a height from a bottom of the first trench to a topmost end of the first fin pattern in a region in which the contact intersects the first fin pattern being a first height, and a height from the bottom of the first trench to a topmost end of the second fin pattern in a region in which an extension line of the contact extending along a direction in which the gate electrode extends intersects the second fin pattern being a second height, the first height being smaller than the second height.
