About “Chip 4” alliance :
- The “Chip 4” or “Fab 4” alliance includes four of the world’s top producers of semiconductors: the U.S., Japan, Taiwan, and Korea.
- It represents more than 70 percent of the value of the global semiconductor industry.
- It was first proposed by the US in March 2022 as part of wider plans aimed at enhancing the "security" and "resilience" of semiconductor supply chains, including by reducing the world's reliance on chips made in China.
- It is intended to cooperate on policy implementation that would support sustainable semiconductor manufacturing in the member states’ home countries.
- Goals:
- Support industry efforts to diversify their manufacturing base in semiconductor production.
- Protect the Intellectual Property (IP) of companies in member countries.
- Develop policies regarding the export of the most advanced semiconductors and equipment.
What is a Semiconductor?
- Semiconductors are materials that have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics).
- They can be pure elements, such as silicon or germanium, or compounds like gallium arsenide or cadmium selenide.
- Due to their specific electrical properties, semiconductors serve as a foundation for computers and other electronic devices.
- Semiconductors are used in many electrical circuits because of the ability to control the flow of electrons in this material, for example, with a controlling current.
