Chinese High-Purity Quartz Gains Qualification for DRAM Manufacturing

Jiangsu Pacific Quartz has obtained qualification for high-purity quartz materials and components in domestic DRAM manufacturing, according to Tom's Hardware. The company already supplies high-purity quartz to chipmaking-tool producers including Lam Research and Tokyo Electron, the article says. High-purity quartz is used in semiconductor manufacturing equipment and consumables, making local qualification relevant to efforts to reduce supply-chain exposure in China's chip industry. The article cites an analyst's view that the domestic DRAM manufacturer may be CXMT, but it does not state that the company confirmed this identification. The supplied material does not disclose the qualified material volume, customer name, production impact, or whether the qualification will replace imports. The development is a materials-supply-chain signal rather than evidence of an immediate increase in DRAM output.
