China's premiere memory-maker YMTC plans two additional Wuhan fabs using homegrown chipmaking tools — Phase 3 crosses 50% domestic tooling threshold

China's Yangtze Memory Technologies (YMTC) is expanding its memory production with plans for two new fabs in Wuhan, in addition to the Phase 3 plant set to be completed this year. Each new plant will have the capacity to produce 100,000 wafers per month, doubling YMTC's current output. With over 50% of Phase 3's equipment sourced domestically, YMTC is testing the viability of Chinese chipmaking tools for high-volume 3D NAND production. The company aims to increase DRAM and NAND production, with a focus on developing through-silicon via packaging for high-bandwidth memory. Despite challenges, YMTC holds a significant share of the global NAND market and is projected to grow further by 2028.
