Semiconductors are the lifeblood of modern technology, powering everything from smartphones to artificial intelligence systems and military defense systems. Taiwan, a small island country, is at the center of this industry, with it dominating most of the world’s chip production. But how did Taiwan get so powerful, and why is its semiconductor industry a U.S.-China hot button?
The 1970s–1980s: Taiwan’s Early Bet on Semiconductors
Government-Led Industrial Shift
In the past, Taiwan was a place for cheap manufacturing, but in the 1970s, the government began to shift its focus to high-tech-based industries, and particularly to semiconductors. In 1974, the Industrial Technology Research Institute (ITRI) was established to provide the necessary skills for laying the ground for Taiwan’s chip industry.
U.S. Assistance in Taiwan’s Semiconductor Growth
The United States partnered with Taiwan for the acquisition of semiconductor technology from RCA and for training engineers abroad. These engineers returned with knowledge used by Taiwan to develop its own semiconductor ecosystem.
The 1980s–1990s: TSMC and The Foundry Model
The Birth of TSMC
Taiwan Semiconductor Manufacturing Company (TSMC) was established in 1987 with government backing. TSMC was different from conventional chipmakers in that it invented the “pure-play foundry” business model— manufacturing only, but not designing chips.
This enabled fabless firms such as NVIDIA, Qualcomm, and Apple to design chips and have them produced by TSMC. The model changed the industry and made Taiwan an indispensable player in semiconductor manufacturing.
Outpacing Competitors
During the 1990s, Taiwan surpassed Japan and South Korea in terms of efficiency and innovativeness. Despite their own manufacturing of microchips, providing flexibility and rapid scalability like TSMC’s by its foundry model, Intel and Samsung also designed chips.
The 2000s–2020s: Taiwan’s Semiconductor Dominance
Market Leadership
Taiwan now controls over 60% of the global semiconductor foundry market. TSMC produces alone:
- 90% of the world’s leading-edge chips (5nm & 3nm nodes)
- Apple iPhone chips, NVIDIA graphics chips, AMD processors, and Tesla AI chips
- Leading-edge semiconductors years ahead of Intel and Samsung
AI and GPUs: Taiwan’s Critical Role
As AI is exploding, there are demands for high-performance GPUs. TSMC manufactures advanced AI chips powering:
- ChatGPT and AI models
- Self-driving vehicles (Tesla, Waymo, etc.)
- Supercomputers and military applications of AI
Any disruption of Taiwan’s chip supply would severely impede worldwide AI development.
The U.S.-China Semiconductor Battle
Why Taiwan is a Geopolitical Flashpoint
America counts on Taiwan for world-class semiconductors, but China is eager to monopolize this important technology. But:
- America has restricted China’s access to Taiwan’s world-class chips, crippling Huawei and China’s AI ambitions.
- China is spending billions on domestic semiconductor manufacturing (SMIC) but is still several years behind Taiwan.
Could China Seize Taiwan for Its Chip Industry?
China has been saying for a long time that Taiwan is theirs and therefore ma
y use force, but a coerced occupation would:
- Spell all-out war with the U.S. and its allies
- Break Taiwan’s semiconductor machinery
- Hurt China’s own tech industry instead of furthering it
Taiwan’s semiconductor industry is more than a high-tech hub—it’s an issue of global security.
The U.S. Response: The CHIPS Act and Supply Chain Shift
To reduce reliance on Taiwan, the U.S. passed the CHIPS and Science Act (2022), investing $52 billion in domestic semiconductor production. Some of the key initiatives are:
- New TSMC facilities in Arizona to bring cutting-edge chip production to the U.S.
- Increased collaboration with Japan, South Korea, and Europe to diversify supply chains.
Conclusion: Taiwan’s Chip Industry Shapes the Future
- Taiwan’s semiconductor dominance is no accident—it’s the product of decades of investment, innovation, and global partnership.
- TSMC’s foundry model revolutionized the business, and Taiwan is now irreplaceable to the world’s technology landscape.
- The U.S.-China semiconductor battle puts Taiwan at the center of global tensions.
- The future of AI depends on Taiwan’s advanced chips, making it the most strategically important tech hub on Earth.
Semiconductors are the new oil—whoever controls them controls the future.
