Abstract

Parallel fins are formed (in a first orientation), and source/drain structures are formed in or on the fins, where channel regions of the fins are between the source/drain structures. Parallel gate structures are formed to intersect the fins (in a second orientation perpendicular to the first orientation), source/drain contacts are formed on source/drain structures that are on opposite sides of the gate structures, and caps are formed on the source/drain contacts. After forming the caps, a gate cut structure is formed interrupting the portion of the gate structure that extends between adjacent fins. The upper portion of the gate cut structure includes extensions, where a first extension extends into one of the caps on a first side of the gate cut structure, and a second extension extends into the inter-gate insulator on a second side of the gate cut structure.
