TSMC's Nvidia Focus Lets China's SMIC Gain Ground in Chips 2026

TSMC's intense focus on Nvidia and advanced nodes has inadvertently opened the door for China's SMIC to gain ground in the semiconductor market. While TSMC, Intel, and Samsung battle for 2nm supremacy, Chinese foundries are capitalizing on the less glamorous but high-volume mature chip segment.

TSMC's Nvidia Obsession and the Advanced Node Race

TSMC has been pouring resources into advanced process nodes to meet the insatiable demand from Nvidia and other AI chip designers. This strategic focus, while lucrative, has led to what some analysts call a "neglect" of other markets, particularly mature nodes.

The advanced node race is incredibly expensive. Producing chips at 2nm and below requires massive capital investment and cutting-edge technology. TSMC, Intel, and Samsung are all in a fierce battle to lead this segment, but it represents only about 20% of the global chip market.

China's SMIC: The Quiet Giant of Mature Chips

Semiconductor Manufacturing International Corp (SMIC) has emerged as the cornerstone of China's semiconductor industry. Alongside Huawei, SMIC is spearheading the government's plan to reduce dependence on foreign chips.

SMIC's strategy is clear: focus on volume over sophistication. While the world's leading foundries chase nanometer supremacy, SMIC and other Chinese foundries are dominating the mature node market, which serves a wide range of applications from consumer electronics to automotive.

This approach is paying off. China's integrated circuit exports surged to over $43 billion in January and February, a 21.8% increase year-over-year. This growth indicates that China is becoming a major player in the global chip supply chain, albeit in less advanced technologies.

Why Mature Nodes Matter

Mature nodes, typically 28nm and above, are essential for many industries. They are used in power management, sensors, microcontrollers, and radio frequency components. The demand for these chips is stable and growing, especially with the rise of IoT and electric vehicles.

By focusing on mature nodes, SMIC avoids the high costs and technical challenges of advanced nodes while still capturing a significant portion of the market. This strategy also aligns with China's goal of self-sufficiency in semiconductors.

The Impact on the Global Semiconductor Landscape

The shift in focus has several implications. First, it reduces the global reliance on TSMC for mature node chips, which could alleviate supply chain pressures. Second, it allows China to build up its domestic semiconductor ecosystem, reducing vulnerability to export controls.

However, this doesn't mean China is catching up in advanced technology. The gap in cutting-edge chips remains wide, and the US and its allies continue to lead in that arena. But in the mature node segment, China is becoming a formidable competitor. The background to this story is set out in SMIC Matches TSMC Chip Density Without EUV Machines, Redefining Foundry Race.

What to Watch Next

As TSMC continues to prioritize advanced nodes for Nvidia and other AI customers, SMIC and other Chinese foundries are likely to expand their mature node capacity. This could lead to oversupply in some segments, but it also positions China as a key supplier for industries that don't require the latest technology.

For companies reliant on mature chips, diversifying suppliers to include Chinese foundries could be a strategic move. However, geopolitical tensions and export restrictions may complicate such decisions. Context on how this played out before sits in Intel's Master Plan to Challenge TSMC by 2027: Can It Succeed.
