The Silicon Island Legacy: Five Decades of Taiwan’s Semiconductor Industry
I. Industrial Development Trajectory: Four Key Phases of Transformation
1. Incubation Phase (1970–1985) — Laying the Technological Foundation
The establishment of the Industrial Technology Research Institute (ITRI) in 1973 marked the beginning of Taiwan’s semiconductor legacy. Through technology transfer from RCA in the United States and the dispatch of engineers for overseas training, a group of so‑called “seed engineers” returned to Taiwan and laid the groundwork for process technologies and talent development.
Ø Key Milestones:
Establishment of ITRI and the Electronics Research and Service Organization (ERSO).
Execution of the RCA technology transfer program.
Formal establishment of the Hsinchu Science Park in 1980.
2. Growth Phase (1985–2000) — A Revolution in Business Models
The founding of Taiwan Semiconductor Manufacturing Company (TSMC) in 1987 by Dr. Morris Chang introduced the world’s first pure‑play foundry model. This innovation allowed fabless IC design companies to focus exclusively on design without bearing the enormous capital burden of fabs, fundamentally reshaping the global semiconductor industry.
Ø Key Milestones:
Establishment of TSMC and the definition of the pure‑play foundry positioning.
Formation of a vertically specialized semiconductor supply chain.
Mainstream wafer sizes advanced from 6‑inch to 8‑inch.
3. Expansion Phase (2000–2020) — A Global Manufacturing Powerhouse
Taiwan gradually took the lead in advanced process technologies. With the explosive growth of smartphones and mobile communications, companies such as MediaTek, UMC, and ASE formed a comprehensive industrial cluster. Taiwan became the heart of global electronics manufacturing, securing world leadership in wafer fabrication and packaging and testing.
Ø Key Milestones:
Process nodes progressively surpassing global competitors.
Rapid growth in demand for mobile communications and consumer electronics chips.
Packaging technologies advancing toward heterogeneous integration such as SiP and PoP.
4. Leadership Phase (2020–Present) — A Global Strategic Hub and the “Silicon Shield”
With the mass production of 3 nm and the advancement toward 2 nm technologies, TSMC has reached the pinnacle of semiconductor manufacturing, becoming the core supplier for global AI and high‑performance computing (HPC) supply chains. As semiconductors are now regarded as strategic resources, Taiwan’s manufacturing capacity and technological leadership are not only economic pillars but also a critical “silicon shield” safeguarding global supply‑chain stability and security.
Ø Key Milestones:
Global leadership in 3 nm and 2 nm advanced processes.
CoWoS advanced packaging emerging as a key enabler for AI chips.
Taiwan becoming an indispensable “strategic security anchor” in geopolitics.
II. Core Competitive Advantages: Why Taiwan?
Taiwan’s pivotal role in the global semiconductor industry does not stem from a single company or a single process‑node breakthrough, but rather from the long‑term accumulation of a highly mature manufacturing ecosystem. Since the establishment of the pure‑play foundry model, Taiwan’s semiconductor industry has focused strictly on process technologies, deliberately avoiding product‑level competition with its customers. This has enabled global IC design houses to entrust their most advanced and critical products to Taiwan based on a foundation of deep trust. This model has successfully attracted leading international customers to commit long‑term wafer volumes, creating a virtuous cycle among scale, yield improvement, and process learning speed—forming an industrial foundation that is extremely difficult to replicate or displace. Building upon this foundation, Taiwan has developed the world’s most dense and complete semiconductor cluster, encompassing IC design, wafer fabrication, advanced packaging and testing, as well as equipment, materials, and fab engineering services. The high degree of geographic and industrial clustering enables rapid cross‑company and cross‑disciplinary collaboration to address the complex challenges encountered during process development and mass production. This significantly shortens learning curves and trial‑and‑error cycles. For highly complex technologies such as advanced nodes and heterogeneous integration, this real‑time collaborative capability has become an indispensable competitive advantage.
Supporting these industrial strengths is a long‑standing and coherent coordination mechanism among government, academia, and industry. Through institutional platforms such as ITRI and the National Science and Technology Council (NSTC), academic and research institutions undertake high‑risk early‑stage process development and pilot validation that are difficult for production‑oriented industries to pursue independently. This division of labor not only reduces uncertainty in technological evolution but also ensures that key process and equipment technologies are thoroughly validated before entering mass production, forming a structural, institutionalized competitive advantage for long‑term industrial development.

IV. Future Outlook
With the rapid advancement of artificial intelligence (AI) and high‑performance computing (HPC), semiconductors are no longer merely key components supporting industrial operations; they are increasingly becoming strategic resources tied directly to national competitiveness and technological security. Leveraging continued leadership in advanced process technologies and a comprehensive ecosystem spanning design, manufacturing, packaging and testing, materials, and equipment, Taiwan will continue to play an indispensable role in driving global digital transformation and technological innovation. Looking ahead, semiconductor technologies will evolve toward greater complexity and deeper system integration. Key directions include the continued advancement of sub‑2 nm processes and three‑dimensional integrated circuits (3D ICs) to address fundamental limits in performance, power consumption, and density. Through heterogeneous integration and advanced packaging, system‑level performance will be enhanced while manufacturing flexibility is improved. At the same time, compound semiconductors such as GaN and SiC will see accelerated deployment in high‑power, high‑frequency, and automotive applications.
Emerging applications—including AI, automotive electronics, quantum technologies, and advanced sensing—will continue to drive demand for leading‑edge processes and innovative system architectures. Within this development landscape, academic and research institutions will play a critical role in forward‑looking process R&D, key equipment validation, and pilot production, serving as essential pillars supporting the industry’s transition to the next generation of semiconductor technologies.
