SemiAnalysis: Naura Technology accelerates the localization of China's etching sector, holding the leading market share in Changxin Memory's ICP etching market.

Independent semiconductor and AI research firm SemiAnalysis noted in a report that China’s localization process for etching equipment is accelerating, with progress clearly outpacing that of deposition equipment. Data shows that year-to-date, etching equipment imports among China’s front-end equipment have dropped 18% year-over-year, while deposition equipment imports have risen 3% year-over-year. SemiAnalysis believes this indicates that China’s domestic substitution in the etching sector has achieved substantial breakthroughs. Financial results from global etching leaders corroborate this judgment: Applied Materials’ China revenue fell 16% year-over-year in fiscal 2025, while Tokyo Electron’s China revenue dropped 18% year-over-year in fiscal 2026. SemiAnalysis points out that North Huachuang is a key driver of this trend; channel research shows it holds the leading share in the ICP etching market at ChangXin Memory. As ChangXin continues expanding production, North Huachuang is expected to further consolidate its market share and scale up its revenue.
