Tantalum CMP Slurry Market Growth to Accelerate by 2035 Driven by GAA Transistor Adoption - News and Statistics - IndexBox

According to IndexBox's market analysis report, the tantalum CMP slurry market is expected to accelerate growth by 2035, primarily driven by the widespread adoption of GAA (Gate-All-Around) transistor... Read original →

The mass adoption of GAA transistors below the 3nm node is triggering structural demand for tantalum-based CMP slurries. Technically, GAA’s intricate nanosheet stacking demands ultra-precise metal planarization, raising purity and slurry formulation thresholds—forcing material suppliers into tighter co-development with equipment makers. On compliance, escalating U.S. export controls on advanced tools compel fabs in Taiwan, China; South Korea; and mainland China to pre-secure critical materials, inflating supply chain security costs. In market positioning, Cabot Microelectronics and Fujimi are expanding capacity, while Chinese players like Anji Microelectronics risk being confined to low-end segments without breakthroughs in high-purity tantalum powder synthesis. Over the next 18 months, as AI chip volumes surge and 2nm R&D accelerates, tantalum CMP slurry will shift from a consumable to a process bottleneck—granting pricing power to suppliers mastering atomic-level surface control.
