Structures for a field-effect transistor and methods of forming a structure for a field-effect transistor. A gate structure is formed over a channel region of a substrate. A first source/drain region is positioned in the substrate adjacent to a first sidewall of the gate structure, a second source/drain region is positioned in the substrate adjacent to a second sidewall of the gate structure, and an extension region is positioned in the substrate. The extension region includes first and second sections that each overlap with the first source/drain region. The first and second sections of the extension region are spaced apart along a longitudinal axis of the gate structure. A portion of the channel region is positioned along the longitudinal axis of the gate structure between the first and second sections of the extension region.
