Global CVD SiC Focus Ring Market was valued at USD 102 million in 2026 and is projected to reach USD 211 million by 2034, registering a CAGR of 11.3% during the forecast period 2026–2034. Growth momentum remains aligned with expanding semiconductor fabrication capacity and the transition toward larger wafer formats and advanced plasma processing requirements.

CVD SiC focus rings are silicon carbide-based chamber components used in semiconductor manufacturing equipment, particularly plasma etch and PECVD systems. These rings help maintain plasma uniformity, stabilize process conditions, and improve etch and deposition precision across wafer surfaces. Their high thermal conductivity, plasma resistance, and mechanical durability make them essential consumable parts in advanced-node and high-volume wafer fabrication environments.
