Abstract:
Embodiments of the present disclosure describe techniques for revealing a backside of an integrated circuit (IC) device, and associated configurations. The IC device may include a plurality of fins formed on a semiconductor substrate (e.g., silicon substrate), and an isolation oxide may be disposed between the fins along the backside of the IC device. A portion of the semiconductor substrate may be removed to leave a remaining portion. The remaining portion may be removed by chemical mechanical planarization (CMP) using a selective slurry to reveal the backside of the IC device. Other embodiments may be described and/or claimed.
