According to media reports, on August 12 local time, the US Department of Commerce's Bureau of Industry and Security announced that starting August 15,Adding diamond and gallium oxide semiconductor materials, ECAD (EDA) software necessary for GAAFET architecture integrated circuits, and pressure-gain combustion technology for gas turbine engines to the commercial control list,Control their exports.

It is understood that GAAFET is a more advanced technology compared with FinFET. FinFET technology can achieve up to 3nm, while GAAFET can achieve 3nm and below. Gallium oxide and diamond are the fourth generation semiconductor materials.

EDA is an indispensable part of chip IC design, is a widely used advanced form of technology, belongs to the upstream industry of chip manufacturing,It covers all processes of IC design, wiring, verification and simulation. EDA is known in the industry as “ The mother of chips. .

In other words, the U.S. ban will limit the export of EDA software to China, which can be used in the design of advanced semiconductor process chips of 3nm and below. The move will limit the breakthrough of Chinese chip designers into advanced processes of 3nm and below.

At present,The global EDA software is mainly monopolized by Cadence, Synopsys, Mentor and other three American enterprises.With more than 70% OF THE GLOBAL MARKET share, it can provide complete EDA tools, covering the whole or most of the integrated circuit design and manufacturing process.
