## How to use this dossier

Read for a causal chain, not a hero story: inherited problem → contribution → mechanism → downstream capability → limit. Then close the page and complete the reconstruction exercise from memory.

## 1. Historical orientation

Morris Chang (born 1931) is an engineer and executive who founded Taiwan Semiconductor Manufacturing Company in 1987 after a career at Texas Instruments and work in Taiwan's technology institutions. TSMC committed to being a pure-play foundry: it manufactures chips designed by customers rather than competing with them through a branded product line. Contract semiconductor manufacturing existed before TSMC, so 'invented the foundry' is too absolute; Chang's achievement was making the dedicated model trusted, technologically leading, and economically scalable. The result separated capital-intensive fabrication from chip design and enabled many fabless companies, while also creating geographic and supply-chain concentration.

## 2. The problem inherited

Advanced fabrication plants demanded enormous investment, preventing small design teams from building chips and making potential customers wary that an integrated manufacturer might appropriate or compete with their designs.

## 3. The central contribution

Chang established a neutral, dedicated foundry business whose process technology, confidentiality, design interfaces, and pooled production capacity let independent firms bring chip designs to market.

## 4. Reconstruct the mechanism

1. Publish process design rules, device models, libraries, and qualification targets that customers can design against.
2. Aggregate orders from many fabless customers to keep expensive fabrication equipment utilized across product cycles.
3. Fabricate customer layouts through controlled wafer processes, measure yield, and feed manufacturing data back into process improvement.
4. Maintain customer neutrality and protect design information so firms can outsource production without funding a fab or empowering a product rival.

## 5. What changed downstream

- The fabless–foundry split lowered entry barriers for specialized chip companies.
- TSMC became a central manufacturing platform for mobile, graphics, networking, and AI processors.
- Shared process ecosystems connected electronic-design automation, intellectual-property blocks, packaging, and manufacturing.

## 6. Attribution, limits, and uncertainty

- Foundry services and merchant fabrication had precedents; TSMC industrialized a dedicated model rather than creating it from nothing.
- TSMC's results depend on engineers, suppliers, public policy, customers, and a highly skilled workforce, not founder action alone.
- Concentration improves scale but produces geopolitical, disaster, energy, water, and systemic supply risks.

## 7. Reconstruction lab

Model two chip startups choosing between a $15 billion shared fab and separate fabs under uncertain demand. Calculate utilization and unit cost across three scenarios, then add confidentiality and supply-concentration risks that a cost-only model misses.
