The relentless scaling of 3D NAND and EUV-based logic chips is thrusting semiconductor-grade disilane into a critical supply chain chokepoint. Technically, disilane’s role in ALD for high-k dielectrics and silicon epitaxy demands parts-per-trillion purity—directly impacting yield at sub-3nm nodes and forcing gas suppliers to overhaul purification capabilities. On compliance, expanded U.S.-Japan-Netherlands export controls now cover precursor chemicals, leaving Chinese fabs reliant on Entegris or SK Materials despite local alternatives, inflating wafer costs by 10–15%. Strategically, Korean and Japanese material firms are locking in long-term deals with Samsung, SK Hynix, and TSMC (Taiwan, China), while Chinese rivals leverage YMTC and CXMT expansions to gain footholds. Over the next 12–24 months, disilane will emerge as a hidden bottleneck; its localization pace will dictate how quickly Chinese foundries can viably scale to 2nm-class processes.
