    Abstract: Semiconductor devices are provided. A semiconductor device includes a substrate including a device region defined by a trench in the substrate. The semiconductor device includes a plurality of fin-shaped active regions spaced apart from each other in the device region and extending in a first direction. The semiconductor device includes a protruding pattern extending along a bottom surface of the trench. Moreover, an interval between the protruding pattern and the plurality of fin-shaped active regions is greater than an interval between two adjacent ones of the plurality of fin-shaped active regions.

    Abstract: A semiconductor device includes a first PMOS transistor, a first NMOS transistor, and a second NMOS transistor connected to an output node of the first PMOS and NMOS transistors. The first PMOS transistor includes first nanowires, first source and drain regions on opposite sides of each first nanowire, and a first gate completely surrounding each first nanowire. The first NMOS transistor includes second nanowires, second source and drain regions on opposite sides of each second nanowire, and a second gate extending from the first gate and completely surrounding each second nanowire. The second NMOS transistor includes third nanowires, third source and drain regions on opposite sides of each third nanowire, and a third gate, separated from the first and second gates, and completely surrounding each third nanowire. A number of third nanowires is greater than that of first nanowires. The first and second gates share respective first and second nanowires.

    Abstract: An integrated circuit device includes a base burying insulating film covering a lower side wall of a fin-type active region on a substrate, an isolation pattern having a top surface higher than a top surface of the base burying insulating film, and a gate line covering a channel section of the fin-type active region. The gate line has an upper gate covering an upper portion of the channel section and a lower gate protruding from the upper gate toward the substrate and filling a space between a lower side wall of the channel section and an upper side wall of the isolation pattern.
