    Abstract: A semiconductor device includes a first transistor and a second transistor. The first transistor includes a first nanowire extending through a first gate electrode and between first source and drain regions. The second transistor includes a second nanowire extending through a second gate electrode and between a second source and drain regions. The first nanowire has a first size in a first direction and a second size in a second direction, and the second nanowire has a second size in the first direction and substantially the second size in the second direction. The first nanowire has a first on current and the second nanowire has a second on current. The on current of the first nanowire may be substantially equal to the on current of the second nanowire based on a difference between the sizes of the first and second nanowires. In another arrangement, the on currents may be different.

    Abstract: A fin field effect transistor includes a first fin structure and a second fin structures both protruding from a substrate, first and second gate electrodes on the first and second fin structures, respectively, and a gate dielectric layer between each of the first and second fin structures and the first and second gate electrodes, respectively. Each of the first and second fin structures includes a buffer pattern on the substrate, a channel pattern on the buffer pattern, and an etch stop pattern provided between the channel pattern and the substrate. The etch stop pattern includes a material having an etch resistivity greater than that of the buffer pattern.

    Abstract: Tunneling field effect transistors are provided. The tunneling field effect transistor includes a source region, a drain region, and a channel region disposed between the source region and the drain region. The channel region includes a first region adjacent to the source region and a second region adjacent to the drain region. A first energy band gap of the first region is lower than a second energy band gap of the second region, and the first region has a direct energy band gap.
