What is worried about Lao Mei is that China Optical Equipment passes through massive verification, and the process of 7nm or above is fully covered!

2024-11-03 18:42:43

Chinas semiconductor field has ushered in major breakthroughs!

The T150 A light -engraved glue product launched by a technology company in Wuhan has now passed massive verification, and the process of 7nm or more is covered.This also means that in terms of chip manufacturing, China has finally mastered key materials in its own hands, completely breaking the foreign monopoly!

So have my country have reached the world -class level in terms of lithography glue technology?

Is there still a gap with developed countries in the United States?

1. Domestic photochemical glue passes through mass production verification

What is light -engraved glue?This is a polymer film material to be used in a chip manufacturing process.

A aggregation or solving reactions occur during the light engraving process, so as to leave the pattern on the silicon wafer.

Internationally, Japans optical glue technology is the strongest. As early as the 1960s and 1970s, Japan already had the independent intellectual property rights of the photoc.The technology is firmly held in hand, and it is the first to create a technical barrier in the photoresists industry. With the commercialization of Japans photoresist, industrial barriers are finally realized.

It is worth mentioning that my country ’s research in the field of lithography has actually did not lag behind Japan in the early days.

In 1962, the Chinese Academy of Sciences commissioned Beijing Chemical Plant to study lithography. In 1967, Chinas first KPR type negativeness In the next three years, my country has successively developed a variety of photoresist.And in 1972, my country even created the first light carving machine.

It can be said that the development of my countrys early in the field of semiconductor cannot be said This has a gap for decades.

Then since my country started early, the early technological research and development progress was also very good. Why did it gradually lag behind?

For the case of light -engraved glue, this is because the Japanese giant monopolized the most advanced photoresist technology, and established industry barriers to formulas and raw materials. In addition, my country at that time at that time Development is relatively backward, the scientific researchers are insufficient, and the R & D funds are also short. The size of the domestic market is very small, which greatly limits my countrys early development in the semiconductor field, so we gradually lag behind.

In these years, as my country has continued to make breakthroughs in the semiconductor field, in order to avoid being overtaken by my country, the Japanese giants have also begun sanctions on my country. Block, for example, last year, Japan limited the export of 23 semiconductor manufacturing equipment.

And my countrys main import channels for equipment and consumables are Japan in the semiconductor field. It is undoubtedly that Japan does this to completely kill the development of the Chinese semiconductor industry.

Among them, if my country still wants to develop a chip independently, it is inseparable from light -engraved glue. In this context, Chinese companies have pursued it. At the time, as domestic photoresia passed the verification of massive production, and the process technology of chips above 7nm or more, we no longer have to worry about being "stuck in the stuck" abroad.

2. How much is there a gap between China Optical Carp Hand and Japan?

However, the most advanced photoresistic process technology in foreign countries has reached 3mm, and in the next 10 years, it is expected to achieve 1Nm, so my country Optical Carving Planes and Plug -in Planes and Plug -in Planes and Plug -in Planes and Plug -in Planes and Plug -in Planes and Plug -in Planes and Glores of China and Plug -in Planes and Glipper and Plug -in Planes and Plug -in Plug -in in China The gap between Japan is still very large, and the most difficult step in my countrys enterprises in the next thing is to realize the optical glue of the 3nm process. If it can break the technical bottleneck, then the Chinese light carved glue will reach the worlds first -class level or even the leading level in the future. The remaining time is the problem.

In addition, there is no use in domestic photochemical glue. It depends on the domestic rate and market share. At the same timeIt is still necessary to create an advanced lithography machine.

Five of the worlds current five photoresistic plastic manufacturers, 4 of which are from Japan, and they hold more than 70%of the worlds market share.

and my countrys domestic photoblasting global market accounts for less than 5%, even in the domestic market, it accounts for less than 25%.

So the domestic photoretime glue market in the short term still depends on Japans import.

Not to mention that the light -engraved glue is not enough, and the industrial chain of photoresmal glue must be established.In the 1970s, a complete optical glue industry chain was created. The domestic upstream and downstream industries did not have a lack of links, and in -depth cooperation can be conducted.

Here, another difficulty that plagues the development of the semiconductor field in my country is to create an advanced lithography machine.

At this stage, the domestic production rate of my country photocride machines is less than 3%. Although some companies in my country have created a DUV light carved machine some time ago, the gap with Asto, the Netherlands is still. Very big.

Therefore, if you want to achieve the technical breakthrough of the entire industrial chain, summarize it in one sentence, it is still a long way to go.

But no matter how difficult it is, if you give up again, then in this field, you will always be "stuck neck" forever.
