What is Chip 4″ or “Fab 4?

The “Chip 4” or “Fab 4” alliance is a group of countries aiming to cooperate on semiconductor (chip) production and supply chains.


  • The alliance consists of the United States, Japan, South Korea, and Taiwan.
  • These countries are powerhouses in the semiconductor industry:
  • The US has major chip design companies like Intel, AMD, and Nvidia.
  • Japan is a leader in chipmaking materials and equipment.
  • South Korea boasts memory chip giants like Samsung and SK Hynix.
  • Taiwan is home to the world’s largest contract chip manufacturer, TSMC.


  • The primary objective is to strengthen the global semiconductor supply chain and reduce reliance on any single country (often seen as an allusion to China).
  • This includes:

Boosting domestic chip production: The alliance aims to encourage member countries to invest in building more chip fabrication plants (fabs) within their borders.

Collaboration on research and development (R&D): Working together to develop next-generation chip technologies.

Securing critical materials and equipment: Ensuring a stable supply of raw materials and equipment needed for chip production.

Protecting intellectual property (IP): Safeguarding the intellectual property rights of member countries’ chip companies.


  • Enhanced Security: A more diversified chip supply chain could lessen the risk of disruptions caused by geopolitical tensions or natural disasters.
  • Technological Advancement: Collaboration on R&D could accelerate innovation in the semiconductor industry.
  • Economic Growth: Increased domestic chip production can create jobs and boost the economies of member countries.


  • Geopolitical Tensions: Navigating complex geopolitical relationships between member countries, particularly regarding China.
  • Balancing Competition and Collaboration: Member countries are also competitors in the chip market, so striking a balance between cooperation and competition is crucial.
  • Implementation: Translating goals into concrete actions and ensuring all members are committed to the alliance’s objectives.

Current Status:

  • The alliance is still in its early stages. The first official meeting of senior officials was held in September 2022.
  • The success of the Chip 4 alliance will depend on the member countries’ ability to overcome these challenges and effectively implement their collaborative efforts.

Overall, the Chip 4 alliance represents a significant development in the global semiconductor industry. Whether it can achieve its goals of a more secure and resilient supply chain remains to be seen.
