Model Answer
The global semiconductor supply chain is highly interdependent and concentrated, with production dominated by a few large players. This structure has evolved over decades, bringing innovation and cost savings, but also creating vulnerabilities.
Market Concentration: A handful of companies control more than 50% of the global semiconductor market. Companies such as Samsung, Intel, and Qualcomm are major players in chip production, making the supply chain dependent on a few firms. This concentration limits competition and increases the risk of disruption if any of these companies face operational challenges.
Geographical Division: Different countries and regions specialize in distinct parts of the semiconductor supply chain, contributing to global interdependence. For instance:
Collaboration in R&D: The semiconductor industry is one of the most research and development-intensive sectors. Major firms often collaborate to drive innovation. For example, ASML, Intel, Samsung, and TSMC teamed up to develop extreme ultraviolet (EUV) lithography, a technology crucial for producing advanced chips.
Risks and Vulnerabilities in the Semiconductor Supply Chain
Several risks and vulnerabilities stem from the interdependence and concentration of the semiconductor supply chain.
Natural Disasters: The geographic concentration of manufacturing in regions like Taiwan and the USA exposes the supply chain to disruptions caused by natural disasters. For example, in 2021, a severe winter storm in the USA and a drought in Taiwan led to significant supply shortages.
Geopolitical Tensions: Countries with strategic control over semiconductor technologies may impose export controls, impacting global access. In 2023, the US, Japan, and the Netherlands imposed restrictions on semiconductor equipment exports to China, raising concerns over supply chain stability.
Global Pandemics: The COVID-19 pandemic highlighted how pandemics can disrupt both supply and demand in the semiconductor industry. Factory shutdowns and surges in demand for electronic devices created significant supply shortages.
Conclusion
While the specialized and concentrated semiconductor supply chain has delivered substantial value, it also presents risks that need to be managed through policies that balance the benefits of scale with resilience to disruptions. The vulnerabilities, such as natural disasters, geopolitical tensions, and pandemics, must be addressed to ensure continued stability and growth in this critical industry.
