What Hormuz Exposed About Our Semiconductor Supply Chain

The recent closure of the Strait of Hormuz has once again highlighted the fragility of the global semiconductor supply chain. Following Iranian strikes that shut the strait since March 4th, helium pri... Read original →

The Hormuz closure laid bare the semiconductor industry’s hidden vulnerability to rare gases. Helium isn’t just a coolant for EUV tools or a leak-detection agent—it’s essential for high-yield HBM and advanced DRAM production. With Qatar’s Ras Laffan offline, Samsung and SK Hynix face acute supply constraints, forcing trade-offs between yield stability and ramp speed. Air cargo disruptions further delay metrology tool deliveries from ASML and KLA, amplifying defect risks. Geopolitical risk has now migrated upstream—from fabs to materials—undermining decades of just-in-time orthodoxy. Over the next 12–24 months, leading IDMs will fast-track helium recycling and regionalize gas sourcing. Simultaneously, the U.S. and EU may weaponize critical material controls, accelerating the fragmentation of the global chip ecosystem.
