China advances domestic quartz supply for chipmaking, but US monopoly persists

China has made progress in securing a domestic supply chain for semiconductor manufacturing components, with Jiangsu Pacific Quartz receiving approval for its high-purity quartz materials. These components are used in chipmaking equipment produced by companies like Lam Research and Tokyo Electron, and have now passed qualification for use in DRAM manufacturing by a domestic Chinese manufacturer, likely CXMT. However, China has not yet overcome the monopoly held by US-based companies, specifically Sibelco and The Quartz Corp. in Spruce Pine, North Carolina, for the specialized crucibles required to grow silicon wafers with the highest purity levels.
