1. Background: A Shifting Semiconductor Landscape
Semiconductors, or microchips, are the heart of modern technology. They are found in a wide range of devices, from smartphones and cars to household appliances and advanced defense systems. As technology continues to evolve, the demand for chips is growing rapidly, with emerging industries such as artificial intelligence (AI) and electric vehicles (EVs) pushing the boundaries of chip design and functionality.
In recent years, the global semiconductor supply chain has been fraught with disruptions, with geopolitical tensions between the U.S. and China exacerbating concerns about dependency on foreign-made chips. The U.S. has long been a leader in the design and innovation of cutting-edge chips, but China has made significant strides in chip manufacturing, aiming to become self-sufficient in the sector and reduce its reliance on U.S. technology.
At the heart of the latest investigation is a focus on "legacy chips," which are semiconductors produced using older manufacturing techniques compared to the most advanced chips used in AI, high-performance computing, and other next-generation technologies. While China remains behind global leaders like Taiwan’s TSMC in producing the most advanced chips, it has become a key player in manufacturing legacy chips at scale.
2. The U.S. Probe: A Deep Dive into Legacy Chinese Semiconductors
The U.S. government’s new investigation focuses on legacy chips, which, although not as advanced as state-of-the-art semiconductors, play a crucial role in various industries. These chips are used in everyday products like automobiles, home appliances, telecommunications infrastructure, and the electrical grid. The investigation will look into China’s policies and practices concerning the production of silicon carbide substrates and other wafers used in semiconductor fabrication.
The U.S. Trade Representative (USTR) initiated the probe under the Trade Act of 1974, specifically utilizing the Section 301 provision. Section 301 allows the U.S. government to investigate unfair trade practices and impose tariffs or other trade restrictions on countries deemed to be engaging in such practices. In this case, the U.S. government has raised concerns about China’s "non-market policies" and "industrial targeting" in the semiconductor sector, which could harm competition and create vulnerabilities in the global supply chain.
3. The U.S. Concerns: National Security and Economic Stability
The main concerns behind the U.S. investigation are national security and economic stability. China's dominance in semiconductor manufacturing, even in the legacy chip segment, presents risks to the U.S., especially given the critical nature of chips in key industries like defense, telecommunications, and energy.
China’s semiconductor industry has long been seen as an extension of the state, with the Chinese government providing significant subsidies and other forms of support to domestic chipmakers. This has raised concerns in the U.S. about "market distortion" and the unfair advantages that Chinese companies may gain through government intervention. Critics argue that such practices undermine competition and lead to over-reliance on Chinese-made chips, creating potential national security risks.
The U.S. also fears that China’s growing semiconductor capabilities could make it more difficult for American companies to maintain their technological edge, particularly in key sectors like AI and advanced computing. While legacy chips are not the focus of cutting-edge innovation, their widespread use in critical infrastructure makes them an essential part of the global technology ecosystem.
4. China’s Response: Pushback and Countermeasures
China’s reaction to the U.S. investigation has been swift and forceful. Beijing has consistently pushed back against U.S. efforts to curb China’s technological rise, viewing such actions as attempts to stifle China’s economic development and limit its access to cutting-edge technology. In response to the Section 301 probe, China may seek to challenge the U.S. actions through international trade organizations such as the World Trade Organization (WTO).
Furthermore, China may explore retaliatory measures, including imposing tariffs on U.S. goods, restricting access to Chinese markets for American companies, or increasing support for its domestic semiconductor industry. Beijing has already made substantial investments in its semiconductor sector, with the goal of achieving self-sufficiency and reducing its reliance on foreign-made chips.
5. Legacy Chips vs. Cutting-Edge Chips: Understanding the Difference
It is important to distinguish between legacy chips and cutting-edge semiconductors. Legacy chips are produced using older manufacturing technologies, typically using nodes larger than 5 nanometers (nm). These chips are less powerful compared to the latest chips used in AI, supercomputing, and other high-tech applications. However, legacy chips still play a crucial role in everyday devices and infrastructure.
While China may not yet be able to produce the most advanced semiconductors, it has become a significant player in the production of legacy chips. Chinese companies such as SMIC (Semiconductor Manufacturing International Corporation) have been able to ramp up production of legacy chips, leveraging older manufacturing nodes that are less costly to produce. This has allowed Chinese firms to dominate the market for chips used in automobiles, telecommunications, and other industrial applications.
In contrast, cutting-edge chips are at the forefront of technological innovation. These chips, produced using advanced manufacturing techniques, are smaller, faster, and more powerful. Companies like Taiwan’s TSMC, South Korea’s Samsung, and the U.S.’s Intel and Nvidia lead the global race in producing the most advanced semiconductors. These chips are essential for applications like AI, data centers, autonomous vehicles, and high-performance computing.
6. Geopolitical Tensions and the U.S.-China Tech War
The semiconductor industry is at the center of a broader geopolitical struggle between the U.S. and China, often referred to as the "tech war." This ongoing battle is about more than just chips; it is about technological supremacy and control over the future of industries that will define the 21st century.
The U.S. has long been the leader in semiconductor design and innovation, but China is determined to catch up. In recent years, Beijing has invested heavily in its semiconductor sector, aiming to reduce its dependence on foreign-made chips and secure its technological future. This has led to a series of confrontations between the two superpowers, with the U.S. taking steps to limit China’s access to advanced technologies.
The U.S. has already imposed significant restrictions on China’s access to advanced semiconductor manufacturing equipment, particularly from companies like ASML (Netherlands) and Applied Materials (U.S.). These restrictions have hindered China’s ability to produce state-of-the-art chips, particularly those with nodes smaller than 5 nm, which are crucial for AI and other cutting-edge applications.
