《TAIPEI TIMES》 US ban on chip tech could hurt China

POTENTIAL SETBACK: Although Chinese chip designers and foundry firms already have US EDA software, they might be unable to update those programs under new US rules

The US’ latest ban on advanced electronic design automation （EDA） software exports to China might hinder Chinese chip companies from accessing advanced semiconductor technology, as they attempt to upgrade to 3-nanometer processes in the next three to five years, market researcher TrendForce Corp （集邦科技） said yesterday.

The US Department of Commerce’s Bureau of Industry and Security on Friday announced bans on EDA tools for gate-all-around field-effect transistors （GAAFET）, a new-generation semiconductor technology that US chipmaker Intel Corp and Samsung Electronics Co from South Korea are adopting to make 4-nanometer and 3-nanometer chips.

The bureau in a statement said that gate-all-around field-effect transistor structure is key to designing ICs used in military equipment, including defense satellites.

Chinese chip designers and foundry service providers lag behind the world’s major chipmakers in developing advanced chips, so the ban of software to design GAAFET technology should not have any substantial effect on them in the short term, the Taipei-based researcher said.

However, “Chinese chip designers will encounter difficulties in designing new-generation chips from the initial design to back-end system design,” TrendForce said in a report.

The world’s top two EDA tool suppliers — Synopsys Inc and Cadence Design Systems Inc, both based in the US — have a combined 62 percent share of the world market, while Siemens EDA, ranked third, has a 13 percent share, TrendForce data showed.

Although Chinese chip designers and foundry companies have already secured a vast amount of EDA software, the companies would still face restrictions from updating those programs for further use in designing chips, the researcher said.

Empyrean Technology Co Ltd （華大九天）, China’s biggest EDA software provider, lags far behind its US peers in terms of technology development and revenue scale, TrendForce said.

Empyrean cannot compete with US rivals in digital circuit design EDA, foundry EDA and next-generation GAAFET design software, it said.

The Beijing-based company is good at providing mature EDA technology including analog circuit and flat-panel display circuit design tools, TrendForce said.

The EDA software market is expected to expand at a compound annual growth rate of 13.8 percent to US$13.6 billion from last year to 2024, it said.

The US Bureau of Industry and Security issued an interim final rule that imposes new export controls on four technologies including additional equipment, software and technology used to produce semiconductors.

One of the four technologies is electronic computer-aided design software specially designed for the development of integrated circuits with GAAFET structure, as well as pressure gain combustion technology, the bureau said in a statement posted on its Web site.

Electronic computer-aided design software is a category of tools used for designing, analyzing, optimizing and validating the performance of integrated circuits or printed circuit boards. It is used in a variety of applications by the military and aerospace defense industries for designing complex integrated circuits, the statement said.

GAAFET technology is key to scaling to 3-nanometer and smaller technology nodes, the bureau said.

GAAFET enables faster, more energy efficient and more radiation-tolerant integrated circuits that can advance many commercial and military applications, including defense and communications satellites, it added.
