Abstract
A tunnel field-effect transistor has a stacked structure including a second active region, a first active region, and a control electrode. The first active region includes a first-A active region and a first-B active region between the first-A active region and a first active region extension portion. A second active region exists below the first-A active region, and the second active region does not exist below the first-B active region. Where an orthographic projection image of the second active region and an orthographic projection image of the first active region overlap with each other is defined as L, and a length in a Y direction of the first active region is defined as L, when an axial direction of the first active region is defined as an X direction, and a stacked direction of the stacked structure is defined as a Z direction, L<Lis satisfied.
