Aiming at GAAFET, is the "disconnected" EDA in the United States this time really serious?

Strictly speaking, although various media rendered the US "disconnected" EDA, from the official text of the Industrial and Security Agency of the US Department of Commerce, saying that "disconnection" is actually not accurate. The specific wording should be restricted exports. The meaning of the two words is different. Naturally, there will be vague space.

There is a knowledge point here, not only the Chinese chip company needs EDA software, but also foreign companies that set up R & D centers in China also need EDA software. Among them, Intel and Qualcomm are the most typical.

If the EDA is "disconnected", what should those American semiconductor companies, South Korean semiconductor companies, and Japanese semiconductor companies in China, which are highly dependent on the Chinese market? Therefore, the use of "disconnection" to describe the United States this time is not accurate.

In addition, not all EDAs are affected, mainly based on GAAFET's EDA software, and exports will face more restrictions.

GAAFET is a new transistor structure. It is a simple popular science. Most of our mobile phone chips now use the FinFET transistor structure. In your own physical limit, encountering quantum tunnels, etc. to destroy the stability of the transistor.

As a result, GAAFET came into being. As a new transistor structure, the industry hopes to use it to break through the physical limit of FinFET and promote the further development of advanced process processes.

At present, Samsung is the fastest semiconductor company to develop GAAFET. In June this year, Samsung announced that it has produced a 3nm chip based on GaaFet, and his first customer is legendary from China.

To be honest, the United States is currently limited to GAAFET -based EDA software exports, in fact, it is "advanced". The entire semiconductor industry has entered the GAAFET era. There are about two or three years. The market impact will be more than two or three years, which is equivalent to giving us a certain buffer time.

Having said that, although the United States is playing new tricks, it is impossible to work immediately, but these precious time will be the key time we vigorously develop software and hardware, catch up, and break through shackles.
