【1】Why Semiconductors Become National Strategy
The reason is clear.
Without semiconductors,
・AI servers
・Communications infrastructure
・Weapons systems
・Automobiles
・Industrial machinery
would all stop.
In other words, semiconductors are the foundational infrastructure of modern society.
【2】The Concentration of Manufacturing in Taiwan
The world’s leading-edge logic manufacturing is concentrated in Taiwan.
TSMC in particular has an overwhelming presence.
TSMC has
・The world’s most advanced nodes
・Enormous production capacity
・Major fabless customers.
For this reason, geopolitical risk in Taiwan is directly linked to the global economy.
【3】The U.S.-China Semiconductor Rivalry
The center of today’s semiconductor geopolitics is the competition between the United States and China.
The United States has imposed
・Export controls on advanced equipment
・EDA restrictions
・Export restrictions on AI chips, and more.
The aim is to curb China’s development of advanced semiconductors.
【4】The Impact of Export Controls
Export controls have a major impact on the supply chain.
Examples:
・A ban on exporting EUV equipment to China
・Export restrictions on AI chips
・Restrictions on advanced manufacturing equipment
As a result, the semiconductor industry is showing a tendency toward technology blocs.
【5】Semiconductor Support Policies in Each Country
National support for the semiconductor industry is increasing rapidly.
Representative examples:
・United States: CHIPS and Science Act
・EU: Chips Act
・Japan: Semiconductor support policies
・China: National semiconductor fund
The aim is to secure domestic manufacturing capacity.
【6】The Risk of Supply Chain Fragmentation
The semiconductor supply chain is extremely complex.
For example, it is an international division-of-labor structure of
・Materials (Japan)
・Equipment (USA, Japan, Europe)
・Manufacturing (Taiwan, South Korea)
・Design (USA)
If any one part stops, the whole stops.
【7】Natural Disaster Risks
Semiconductor supply is also affected by natural disasters.
Examples:
・Earthquakes
・Water shortages
・Power outages
Semiconductor factories require
・Large amounts of water
・A stable power supply.
【8】Logistics Risks
Semiconductors depend on
・Air freight
・Precision transport.
If international logistics stop,
・The supply of components
・Product shipments
come to a halt.
This problem became apparent during the pandemic.
【9】Moves Toward Supply Diversification
In recent years, companies have been diversifying their supply.
Examples:
・Building fabs in the United States
・Attracting fabs to Europe
・Bringing manufacturing back to Japan
The aim is to secure supply stability.
【10】Semiconductors and Economic Security
Semiconductors are at the center of economic security.
Countries are strengthening
・Technology protection
・Export controls
・Investment restrictions.
Companies also need to take political risks into account.
【11】The Future of Semiconductor Geopolitics
Future focal points:
・Taiwan risk
・U.S.-China technology competition
・Competition in national subsidies
・Supply chain restructuring
The semiconductor industry has become an industry of technology + politics.
【12】Summary
・Semiconductors are a national strategic technology
・Concentration in Taiwan is the biggest risk
・The U.S.-China semiconductor rivalry is intensifying
・Export controls are affecting the industry’s structure
・Countries are strengthening domestic manufacturing
