The Story of TSMC

A structural look at how a Taiwanese company became essential infrastructure for the global technology industry.

Introduction

TSMC manufactures chips it does not design. This foundry model, invented by TSMC's founder Morris Chang, transformed the semiconductor industry. Before TSMC, chip companies needed their own factories. After TSMC, they could focus on design while outsourcing manufacturing to a specialist.

Today, TSMC manufactures the majority of the world's most advanced chips. Apple's processors, AMD's CPUs, Nvidia's GPUs, and countless other leading products are made in TSMC's facilities. This concentration of essential capability in a single company creates both extraordinary value and significant strategic concern.

Understanding TSMC's arc reveals how the foundry model created an industry structure that concentrates manufacturing expertise, and how accumulated capability creates advantages that would require decades to replicate.

The Long-Term Arc

What was TSMC's founding foundry concept?

TSMC was founded in 1987 with a revolutionary concept: a semiconductor company that only manufactured, never designed. This pure-play foundry model enabled chip designers to exist without factories. Morris Chang, who conceived the idea, recruited Taiwanese government support to establish the company.

Early success came from serving fabless chip companies—design firms that could not afford their own manufacturing. TSMC provided these companies access to manufacturing capabilities that would otherwise be impossible. The foundry model proved viable, then essential.

How did TSMC build scale and technology leadership?

Through the 1990s and 2000s, TSMC grew by continuously advancing manufacturing technology while serving an expanding customer base. Each technology generation required billions in investment. TSMC made these investments, steadily pulling ahead of competitors who could not match the spending.

The virtuous cycle became apparent: more customers funded more R&D, which produced better technology, which attracted more customers. Scale and technology leadership reinforced each other. Competitors fell behind as the investment requirements exceeded their capabilities.

How did TSMC reach leading-edge dominance?

By the 2010s, TSMC had established clear leadership in advanced manufacturing processes. The company offered the smallest transistors, the best yields, and the most manufacturing capacity at leading-edge nodes. Chip designers who needed the best technology had limited alternatives.

Samsung remained a competitor but also a complex case—as both foundry and chip designer, Samsung competed with some of its potential customers. Intel's manufacturing stumbled, losing the leadership position it had held for decades. TSMC's pure-play focus proved advantageous.

What is TSMC's modern structural position?

Today, TSMC manufactures more than 90% of the world's most advanced logic chips. The company's technology leadership continues extending. Facilities in Taiwan contain production capabilities that exist nowhere else. This concentration has made TSMC essential infrastructure for global technology.

Geopolitical attention has intensified. The United States, Europe, and Japan have all encouraged TSMC to build facilities in their territories. National semiconductor strategies now account for TSMC's position. The company has become strategic infrastructure beyond its commercial role.

Structural Patterns

• Pure-Play Focus — Manufacturing without designing avoids competing with customers. Chip designers share designs with TSMC without fearing competition, enabling trust that integrated competitors struggle to establish.
• Scale Advantages — High fixed costs and low marginal costs favor the largest producer. TSMC's volume enables investment and efficiency that smaller foundries cannot match.
• Technology Leadership — Leading-edge manufacturing attracts customers who need the best. This demand funds continued advancement, extending leadership.
• Capital Intensity as Barrier — New foundries cost tens of billions of dollars. This capital requirement deters entry and protects established positions.
• Manufacturing Expertise — Decades of experience produce yield optimization and process refinement that cannot be quickly replicated. Know-how accumulates.
• Customer Dependency — Chip designers who outsource manufacturing become dependent on their foundry. Switching involves risk and delay.

Key Turning Points

1987: Company Founding — Morris Chang's foundry concept created a new industry structure. This innovation enabled the fabless semiconductor companies that would later include Nvidia, AMD, and Qualcomm.

2010: 28nm Leadership — Achieving leadership at the 28nm process node marked TSMC's emergence as the clear technology leader. This node's success attracted the volume that funded continued advancement.

2016: Apple iPhone Contract — Becoming the exclusive manufacturer of Apple's processors demonstrated TSMC's capability and reliability. The Apple relationship provided revenue stability and technology partnership.

2020: 5nm Production — Reaching 5nm process technology extended TSMC's lead. Competitors struggled to match this capability, widening the technology gap.

2020s: Geopolitical Focus — Government attention to semiconductor supply chain security elevated TSMC's strategic importance. The company became central to national technology strategies worldwide.

Risks and Fragilities

Geographic concentration in Taiwan creates strategic vulnerability. Most of TSMC's advanced production occurs in Taiwan. Regional tensions, natural disasters, or other disruptions could affect global chip supply. This concentration concerns customers and governments worldwide.

Competition from Intel and Samsung continues. Intel is investing heavily to recover manufacturing leadership. Samsung pursues advanced processes and foundry business. While TSMC leads currently, sustained competitive investment creates ongoing pressure.

Capital intensity requires continuous investment. Each technology generation costs more than the last. TSMC must continue spending billions annually to maintain leadership. Any failure to invest appropriately could erode position.

What Investors Can Learn

1. Focus can create advantage — TSMC's pure-play model enables customer relationships that integrated competitors cannot establish.
2. Scale and technology reinforce each other — Volume funds investment; investment attracts volume. This cycle builds compounding advantages.
3. Capital intensity creates barriers — Industries requiring massive investment deter entry and protect leaders who have already invested.
4. Manufacturing expertise accumulates — Know-how developed over decades cannot be quickly replicated. Time creates advantages.
5. Concentration creates strategic importance — Essential capabilities concentrated in one company attract government attention and geopolitical concern.
6. Geographic concentration creates risk — Operations concentrated in one location expose companies to regional disruptions.
