Techniques are provided herein to form semiconductor devices arranged between a gate cut on one side and a deep backside via on the other side. A row of semiconductor devices each include a semiconductor region extending in a first direction between corresponding source or drain regions, and a gate structure extending in a second direction over the semiconductor regions. Each semiconductor device may be separated from an adjacent semiconductor device along the second direction by either a gate cut or a deep backside via. The gate cut may be a dielectric wall that extends through an entire thickness of the gate structure and the deep backside via may include a conductive layer and a dielectric barrier that also extend through at least an entire thickness of the gate structure. Each semiconductor device may include a gate cut on one side and a deep backside via on the other side.
