Global Semiconductor Supply Chain

What is Global Semiconductor Supply Chain?

The Global Semiconductor Supply Chain refers to the complex, interconnected network of companies, processes, and logistics involved in the design, manufacturing, assembly, testing, and distribution of semiconductors also known as microchips or integrated circuits worldwide.

Historical Background

The semiconductor industry originated in the mid-20th century, with significant advancements in the US. Over decades, the supply chain became highly globalized and specialized, with different stages of production concentrated in various countries, driven by cost efficiencies and technological expertise. Taiwan, South Korea, and the US emerged as key players.

Key Points

7 points
  • 1.

    Highly specialized and capital-intensive industry, with distinct stages: design (e.g., US), fabrication/foundry (e.g., Taiwan, South Korea), assembly, testing, packaging (ATP) (e.g., Southeast Asia), and equipment/materials (e.g., Japan, Netherlands).

  • 2.

    Dominated by a few key players: TSMC (Taiwan Semiconductor Manufacturing Company) holds over 50% of the global foundry market share, especially for advanced chips.

  • 3.

    Semiconductors are critical components for almost all modern electronic devices, from smartphones and computers to cars and and defense systems.

  • 4.

    The supply chain is vulnerable to disruptions from geopolitical tensions, natural disasters, trade wars, and pandemics (e.g., COVID-19 chip shortage).

  • 5.

    High barriers to entry due to immense R&D costs, specialized talent, and complex manufacturing processes.

  • 6.

    Strategic importance has led many countries to pursue reshoring or friend-shoring initiatives to build domestic capabilities and diversify supply.

  • 7.

    Taiwan's role is particularly crucial for cutting-edge chips (7nm and below).
