Officially announced by Chinese Academy of Sciences! The breakthrough of the two technologies is no less difficult than that of mask aligner.

Since entering the information age, our domestic scientific and technological level has improved rapidly, and we have mastered certain core technologies in various fields, and the gap with some developed countries is getting smaller and smaller. However, it should be noted that there is still a key technology and equipment in China that needs to be overcome urgently, which is related to the development of domestic chip industry, and that is mask aligner!

I believe everyone is familiar with mask aligner, which is an indispensable equipment in the process of chip manufacturing. It is generally recognized by the whole semiconductor industry that chips cannot be produced without mask aligner. Most people have never heard of mask aligner before, but with the influence of Huawei's chip incident, China has realized the importance of mask aligner.

The reason why Huawei's chips are restricted by American rules is that it has no manufacturing capacity and needs to be supplied by foundries containing American technology. And our country is also in a relatively weak position in the field of chip manufacturing. Although we can independently produce some low-end chips, we can't do anything about chips with advanced technologies such as 7nm and 5nm!

Because of this, after losing its foundry partner, Huawei faced the problem of chip shortage, which magnified the shortcomings of domestic technology. In fact, in chip design and packaging testing, domestic strength is excellent, and it is not lost to foreign countries at all. But let a person feel helpless, because there is no support from mask aligner, domestic chip manufacturing has never been completely overcome!

In order to further promote the development of domestic chips and help Huawei get out of the predicament, China made a decision to comprehensively lay out mask aligner. It is understood that China Academy of Sciences, the institution with the highest level of science and technology in China, has been making efforts in this direction. In the future, the whole hospital will concentrate on overcoming technologies that are easily "stuck" by foreign countries, such as mask aligner!

It can be expected that, with the support of Chinese Academy of Sciences, domestic mask aligner will make continuous progress, and this problem will be solved soon. Not only that, the Chinese Academy of Sciences recently officially announced two technological breakthroughs, which are as difficult as mask aligner! That is to say, besides mask aligner, the Chinese Academy of Sciences has also conquered two extremely difficult technologies!

The first technology is a new type of organic light-emitting diode display material, which has laid the foundation for the mass production project led by Academician Li Yadong of Chinese Academy of Sciences! Organic light-emitting diodes (OLEDs) are the main materials of various screens at present, and the market is very broad. Most of the previous market share was taken away by Samsung in Korea, and we can only get a small share in China.

Although BOE, a domestic screen manufacturer, has also studied organic light-emitting diode materials, compared with Samsung, the gap still exists. In order to make up for this gap, the Chinese Academy of Sciences has stepped in. The research team of new organic light-emitting diode materials led by Academician Li Yadong is working hard to tackle key problems. Before long, domestic organic light-emitting diode screens can replace Samsung!

Organic light-emitting diode (OLED) screen is indispensable for mobile phones, computers and other electronic products, so the research and development work of Chinese Academy of Sciences is necessary. As long as domestic screens can be recognized by people, they can occupy a larger market and gain better development space!

The second technology that the Chinese Academy of Sciences broke through was the chip, which provided a new development direction for domestic semiconductor enterprises. It is reported that in Shanghai Institute of Microsystems, Chinese Academy of Sciences, 8-inch graphene wafers have appeared and can be mass-produced! This means that domestic research on carbon-based chips is ahead of the world. If the wafer can be perfect cut, then the real carbon-based chip will be born!

For a long time, chips are made of silicon-based semiconductor materials. Although the performance in all aspects is not bad, as long as it reaches the limit, it is impossible to continue to make progress. Therefore, many countries around the world have begun to pay attention to carbon-based chips, which have stronger performance and stability. Once they break through, it will definitely lead to changes in the semiconductor industry.

Now it seems that China has made a leading position in the field of carbon-based chips. The appearance of 8-inch graphene wafers means that domestic chips may be able to "change lanes and overtake"! But even this would not be enough If domestic chips want to rise successfully, they must make continuous progress, and both carbon-based chips and silicon-based chips must be seized!

The two pieces of good news released by the Chinese Academy of Sciences are of great significance to domestic technology and can also promote the development of many domestic enterprises! I believe that in the future, China will be able to constantly break through various core technologies and achieve the goal of becoming a powerful country through science and technology. Let's wait and see!
