Abstract
Structures for a field-effect transistor and methods of forming a field-effect transistor. A sidewall spacer is arranged adjacent to a sidewall of a gate electrode, a source/drain region is arranged laterally adjacent to the sidewall spacer, and a contact is arranged over the source/drain region and laterally adjacent to the sidewall spacer. The contact is coupled with the source/drain region. A section of an interlayer dielectric layer is laterally arranged between the contact and the sidewall spacer.
