The semiconductor device includes a gate-all-around transistor having one or more dielectric regions that include or more dielectric gases. The dielectric regions may include a first dielectric region between epitaxial regions (e.g., source/drain regions) and a first portion of a gate structure of the gate-all-around transistor. The dielectric regions may further include a second dielectric region between a contact structure of gate-all-around transistor and a second portion of the gate structure. By including the dielectric regions in the gate-all-around transistor, a parasitic capacitance associated with the gate-all-around transistor may be reduced relative to another gate-all-around transistor not including the dielectric regions.
