Middle East Conflict Disrupts Semiconductor Supply Chain with Chemical Shortages

• April 23, 2026

Expanding tensions and military conflict between the United States and Iran have begun to impact the global semiconductor supply chain, extending far beyond initial concerns over raw material shortages like natural gas and helium. Industry sources highlight emerging difficulties faced by Asian chip makers, particularly in Japan and South Korea, where essential chemical supplies for lithographic processes are becoming scarce.

Critical Chemicals Under Strain Amid Conflict

The semiconductor manufacturing process relies heavily on advanced chemicals used during lithography, a crucial step in defining fine circuit patterns on silicon wafers. These specialized substances are often sourced through complex international supply chains that are sensitive to geopolitical disruptions.

With the ongoing military actions in the Middle East, routes and logistics critical for delivering these chemicals have faced disturbances. Companies in Asia are now confronted with tightening inventories, putting pressure on production capacities and potentially slowing down chip output.

While natural gas and helium supplies remain important to raw material availability, the shortage of these lithography chemicals adds an additional layer of complexity to an already fragile industry sector. Both Japanese manufacturers and South Korean firms are reported to be taking precautionary measures to mitigate the impact but the extent and duration of these shortages remain uncertain.

The semiconductor industry, still recovering from past supply chain shocks, now faces this new challenge that could influence global technology markets. Chipmakers might need to adjust production schedules, seek alternative chemical sources, or accelerate development of more resilient supply networks.

The continuing conflict in the Middle East illustrates how geopolitical strife can ripple through highly interconnected high-tech industries, reminding stakeholders of the vulnerabilities inherent in globalized manufacturing systems.

Ongoing conflict in the Middle East is causing shortages of key chemicals vital to chip manufacturing in East Asia.
