Beyond oil, the conflict disrupts supply chains for materials like sulfur and helium, which are essential for producing copper, cobalt, and components used in semiconductor manufacturing. This creates a significant, non-obvious risk to the global tech industry.

Despite geopolitical tensions, Taiwan's world-leading semiconductor fabs are completely dependent on specialty gases imported from mainland China. An export restriction on a single chemical, like NF3, could shut down the entire Taiwanese chip industry, an often-overlooked vulnerability.

While the CHIPS Act successfully incentivizes fab construction, it fails to address the underlying chemical supply chain. Unlike China's holistic 'Big Fund,' this oversight means new US-based fabs will be totally reliant on imported specialty gases, undermining the goal of supply chain security.

The purity requirements and chemical sets ('recipes') for manufacturing a chip are first developed by equipment manufacturers, not fabs. Fabs like TSMC then receive and optimize these recipes, creating a dynamic between the toolmaker's guarantee and the fab's continuous improvement process.

The extreme energy intensity of advanced chipmaking creates a critical vulnerability. In Taiwan, the world's leading chip producer, a single major manufacturer uses up to 10% of the country's total power. This high-stakes dependency is amplified by Taiwan's limited LNG storage of only about one and a half weeks.

Over 90% of the world's sulfur is a byproduct of oil refining. This sulfur is crucial for producing sulfuric acid, a key chemical in semiconductor manufacturing. Therefore, disruptions to oil shipping or refining create a hidden material supply chain risk for the tech industry, beyond just energy costs for power.

Counterintuitively, the most common safety incidents in semiconductor fabs involve asphyxiation from nitrogen, a benign gas used in massive quantities for creating clean environments. Its ubiquity as a utility gas makes it a more frequent, silent hazard than the more exotic and dangerous process chemicals.

The seemingly delicate process of chip manufacturing is, at the atomic level, an extremely violent one. This violence requires the most reactive, and therefore most lethal, chemicals for processes like etching and deposition. The danger is a direct specification of the job.

Semiconductor fabs are prevented from stockpiling many critical, hazardous gases by strict on-site storage permits. This creates a reliance on a just-in-time, hyper-reliable supply chain, making any disruption an immediate and existential threat to production.
