KLA Corporation, onsemi, and Nova Shares Are Falling, What You Need To Know - The Globe and Mail

Recent reports that SK Hynix is slowing its high-bandwidth memory (HBM) expansion triggered a sharp sell-off in the semiconductor sector, sparking concerns over AI chip demand. Although the move is dr... Read original →

SK Hynix’s HBM capacity moderation reflects capital efficiency—not demand erosion—but triggered a sector-wide selloff due to market misreading. Technically, delayed TSV and advanced packaging tool orders hurt KLA and Nova’s near-term visibility, while NVIDIA’s Blackwell Ultra deployments risk bandwidth bottlenecks if HBM supply tightens, potentially pushing customers toward LPDDR5X and compromising FP64 performance. Geopolitically, U.S.-Dutch export controls on ASML’s EUV tools have already inflated fab allocation costs for foundries in Taiwan, China and Hong Kong, China. Samsung may seize HBM3E share, while Micron deepens vertical ties with Microsoft and Alphabet. Over the next 12–24 months, the industry will pivot from blind capacity expansion to precision alignment of compute and memory bandwidth—favoring IDMs and equipment makers with heterogeneous integration mastery.
