Abstract
A device includes a substrate, a vertical stack of nanostructure channels over the substrate, a gate structure wrapping around the nanostructure channels, and a source/drain region on the substrate. The device further includes a source/drain contact in contact with the source/drain region. The source/drain contact includes a core layer of a first material. A source/drain via is over and in contact with the source/drain contact. The source/drain via is the first material. A gate via is over and in electrical connection with the gate structure. The gate via is the first material.
