The Impact of Water Shortages on Semiconductor Firms

The semiconductor industry, represented by giants like Taiwan Semiconductor Manufacturing Company (TSMC), is facing a growing risk of water shortages as processing technology continues to advance. Companies like TSMC play a crucial role in manufacturing semiconductor chips that are integral to everyday consumer devices such as smartphones and TVs. However, the chip making process requires a significant amount of water to cool machinery and maintain the cleanliness of wafer sheets.

A direct correlation exists between water usage and chip sophistication in the semiconductor industry. Fabs, which are semiconductor fabrication plants, rely on ultrapure water to rinse wafers between each processing step. As semiconductor technology advances and becomes more sophisticated, the number of fabrication processes increases, leading to higher water consumption. For instance, TSMC experienced a significant rise in water consumption per unit when it migrated to 16-nanometer process nodes in 2015.

Potential Disruptions in the Global Tech Supply Chain

Given TSMC’s dominant position in advanced chip manufacturing, any water-related disruptions to its operations could have a ripple effect across the global tech supply chain. The report by S&P Global Ratings highlights the importance of water security for semiconductor firms’ credit profiles. Mishandling of water resources could not only disrupt operations but also impact financial performance and customer relationships.

Strategies for Mitigating Water Shortage Risks

To address the challenges posed by water shortages, semiconductor firms like TSMC may need to adopt strategic measures. For example, TSMC could prioritize the production of more advanced chips over lower-margin mature chips when faced with limited water supply. This shift in focus could potentially boost the company’s earnings and ensure its sustainability in the long run.

The semiconductor industry is expected to witness a steady increase in water consumption due to capacity expansion and the demands of advancing process technology. Chipmakers worldwide already consume a significant amount of water, with the industry’s consumption levels matching that of a city like Hong Kong. As such, water security is poised to become a critical factor in assessing semiconductor firms’ credit profiles and overall viability.

The semiconductor industry’s reliance on water poses a significant challenge as technology advances and water resources become increasingly strained. Companies like TSMC must proactively address water shortage risks to safeguard their operations, financial performance, and customer relationships in the face of growing environmental concerns.
