GoKawiilJiangsu Pacific Quartz clears CXMT qualification for chipmaking components
Chinese high-purity quartz maker Jiangsu Pacific Quartz, which already supplies furnace tubes and wafer boats to Lam Research and Tokyo Electron, has had its quartz components certified by a Chinese DRAM producer believed to be CXMT for 300mm wafer production. The materials meet the 4N5–5N purity level needed for semiconductor process equipment, giving China a more domestic supply chain for chipmaking consumables.
