摘要:
Techniques are provided herein to form semiconductor devices that include a contact over a given source or drain region that extends over the top of an adjacent source or drain region without contacting it. In an example, a semiconductor device includes a gate structure around a fin of semiconductor material that extends from a source or drain region, or one or more nanowires or nanoribbons or nanosheets of semiconductor material that extend from the source or drain region. A conductive contact is formed over the source or drain region that extends laterally across the source/drain trench above an adjacent source or drain region without contacting the adjacent source or drain region. The contact may extend along the source/drain trench through a dielectric wall (e.g., a gate cut) that extends orthogonally through the source/drain trench.
