    Abstract: Some implementations herein provide a semiconductor device and methods for forming the semiconductor device. A multi-layer structure of the semiconductor device includes a metal ring structure and a dielectric sidewall structure along interior sidewalls of the metal ring structure. An interconnect structure (e.g., a through silicon via interconnect structure) is along a central interior axis of the metal ring structure. A protective layer is between the interconnect structure and the dielectric sidewall structure. During a deposition operation that fills a cavity with a conductive material to form the interconnect structure, the protective layer may protect the dielectric sidewall structure from damage to improve a quality and/or a reliability of the semiconductor device.
