The Rise of Taiwan Semiconductor Manufacturing Company
Historical Background
On the northwest coast of Taiwan, nestled between mudflats teeming with fiddler crabs and sweet-scented persimmon orchards, sits the world’s most important company that you’ve probably never heard of. Taiwan Semiconductor Manufacturing Co., or TSMC, is the world’s largest contract manufacturer of the semiconductor chips—otherwise known as integrated circuits, or just chips—that power our phones, laptops, cars, watches, refrigerators and more. Morris Chang, who founded Taiwan Semiconductor Manufacturing Company in 1987, focused the company on chip manufacturing, not design. He did so at the invitation of the Taiwanese government, which was eager to boost the island’s economy at the time.
Key Milestones
TSMC got its start thousands of miles away from Arizona’s arid desert—on the northern coast of Taiwan. Through the vision and leadership of its founder Dr. Morris Chang, TSMC pioneered the pure-play semiconductor foundry business model. TSMC has since remained one of the world’s largest dedicated foundries with fabrication facilities (“fabs”) and subsidiaries spanning Asia, Europe and North America.
Global Impact
TSMC is a critical enabler of today’s technology industry, having fundamentally reshaped the semiconductor landscape in 1987. Its clients include Apple, Intel, Qualcomm, AMD and Nvidia. TSMC, which makes most of its chips in Taiwan, was under pressure to expand its global manufacturing capacities. This expansion is crucial as TSMC continues to play a pivotal role in the global tech ecosystem.
Inside the Clean Room: The Heart of Chip Fabrication
The cleanroom area at TSMC is approximately double the size of an industry standard logic fab. This meticulously controlled environment is where the magic of chip fabrication happens. TSMC is just absolutely critical to the semiconductor ecosystem, controlling the most complicated part of the process. Visitors must don head covers, dust-free jackets, pants, and shoes before passing through an “air shower” to remove errant particles.
Clean Room Protocols
For this reason, TSMC’s foundry is meticulously controlled. All visitors must don head covers, dust-free jackets, pants, and shoes before passing through an “air shower” to remove errant particles.
Advanced Machinery
The extreme ultraviolet lithography machines that TSMC uses each cost around $175 million. Larger fabs will have 20 of them. Creating a chip takes around 1,500 steps, each with 100 to 500 variables. Even if each step’s success rate is 99.9%, that means less than a quarter of the final output is usable.
Worker Experiences
TSMC workers in the “clean room” where fabrication of chips takes place in the company’s Hsinchu headquarters. A worker enters a “clean room” at chipmaker TSMC’s headquarters in Hsinchu, Taiwan, on Sept. 10. The transistor in a 3-nm node is just 1/20,000th the width of a human hair. Were you to enlarge a foot-long wafer of semiconductor to the size of the continental U.S., the required patterning for these chips would still be only the width of a thumbnail.
The Science Behind Semiconductor Manufacturing
Materials and Components
The key component in semiconductor manufacturing is silicon, which is essentially purified sand. The magic happens in how it is processed. The transistor in a 3-nm node is just 1/20,000th the width of a human hair. This level of precision requires advanced materials and components to ensure the highest quality and performance.
Fabrication Process
The fabrication process involves several intricate steps:
- Wafer Production: Silicon wafers are produced and polished to a mirror finish.
- Photolithography: Patterns are transferred onto the wafer using light exposure.
- Etching: Unwanted material is removed to create the desired circuit patterns.
- Doping: Impurities are added to modify electrical properties.
- Metallization: Metal layers are added to form electrical connections.
Technological Innovations
Technological innovations are crucial for advancing semiconductor manufacturing. Companies like TSMC partner deeply with firms like ASML to understand the complexities of the machinery involved. These partnerships are essential for mastering the optics and light refraction techniques required for mass production. The latest generation of chip manufacture, such as 3-nm chips, is expected to be up to 15% faster and use far less power.
Challenges in Maintaining Semiconductor Quality
Quality Control Measures
Maintaining the quality of semiconductors is a monumental task, especially given the unbelievably complex and specialized nature of chip manufacturing. The transistor in a 3-nm node is just 1/20,000th the width of a human hair. Were you to enlarge a foot-long wafer of semiconductor to the size of the continental U.S., the required patterning for these chips would still be only the width of a thumbnail. This level of precision necessitates rigorous quality control measures to ensure that each chip meets the required standards.
Impact of Diversification
Making chips is so complex that diversifying the location of fabs will make it more difficult to maintain quality. The key component may only be silicon—or purified sand—but the magic happens in how it is processed and manufactured. Diversification introduces variables that can affect the consistency and quality of the final product. This is one of the biggest challenges with semiconductor manufacturing today.
Future Challenges
The semiconductor industry has contracted even as the chips themselves have grown more prevalent and pivotal. Other than TSMC, the only firm capable of commercially producing today’s most advanced 5-nanometer (nm) chips is South Korea’s Samsung Electronics. However, TSMC is building a new fabrication plant—or “fab”—across 22 football fields of land in southern Taiwan to produce groundbreaking 3-nm chips, expected to be up to 15% faster and use far less power. This latest generation of chip manufacture presents new challenges in maintaining quality, especially as the industry continues to evolve.
TSMC’s Global Influence and Market Control
Market Share and Competitors
TSMC is a $660 billion giant that has allowed “fabless” chip designers such as Nvidia and Apple to flourish. As the world’s semiconductor epicenter, Taiwanese foundries account for 67 percent of the global market and TSMC alone has a market share of 53 percent. Samsung and Intel are still trailing behind the Taiwanese company.
Strategic Partnerships
TSMC has fundamentally reshaped the semiconductor landscape since 1987. Through the vision and leadership of its founder Dr. Morris Chang, TSMC pioneered the pure-play semiconductor foundry business model. The company has since remained one of the world’s largest dedicated foundries with fabrication facilities (“fabs”) and subsidiaries spanning Asia, Europe, and North America.
Economic Impact
TSMC is a critical enabler of today’s technology industry. The scarcity of chips has thrust TSMC from a largely anonymous services company to the center of a global tussle over the future of technology. The firm will play an outsize role in determining what the world looks like at the end of this decade. Some foresee an emerging dystopia, driven by a worsening climate crisis and rising geopolitical tensions between China and the U.S.
