Chinese universities have made another meritorious service, and the United States is doomed to fail with the progress of "* semiconductors".
Although China is the world's largest consumer of chips, a small chip has choked the necks of many Chinese companies.
Because although China has become a major producer of mobile phones, computers, TVs and other products, the best channel for chips is still foreign, because the West has dominated the basic technology for the production of chips.
A small chip, but contains the world's cutting-edge technology, in the network, microelectronics, materials, chemistry, machinery, mathematics and physics and other disciplines, all need to master cutting-edge technology, although Chinese companies have the strength to design high-end chips, but there are serious deficiencies in production.
Taking materials science as an example, the top materials are basically monopolized by the United States and Japan, these two countries occupy the upstream of the United States and Japan's ** chain, which can directly restrict the development of China's semiconductor industry.
This means that in the field of semiconductor materials, our country has no chance;In fact, in recent years, China has accelerated its progress in key semiconductor technologies and achieved significant research results.
In February this year, the 46th Institute of China Electronics Technology officially announced that China's first 6-inch gallium oxide single crystal was successfully prepared, reaching the highest international level, which will strongly support the practical process of gallium oxide materials in China and the development of related industries.
Not long after, there was good news from China's universities: the campus of Xi'an University of Posts and Telecommunications suddenly announced a breakthrough in the field of semiconductor materials, and successfully prepared high-quality gallium oxide epitaxial wafers on 8-inch wafers, which marked important progress in China's research on ultra-wideband semiconductors.
So, are gallium oxide epitaxial wafers really like semiconductor materials, and what are the practical applications?
It is understood that gallium oxide is an ultra-wideband semiconductor material, which has great potential for application in the field of power devices and photovoltaics.
Xi'an University of Posts and Telecommunications has developed gallium oxide epitaxial wafers, which are the most advanced semiconductor materials, compared with previous generations of materials, gallium oxide is characterized by higher breakdown field strength and lower bonding strength, which has a good effect on improving energy conversion.
In addition, gallium oxide materials have excellent chemical properties and have high advantages in industrial applications, which makes it possible to break through the limitations of Moore's law in a new direction.
The current chip production process has fallen into a bottleneck, and the traditional silicon crystal material is difficult to make a higher specification process level due to its high hardness and difficult production, because the limit of Moore's law is not so easy to break.
To break Moore's Law, the best way is to start with new materials, new processes and other fields, and find shortcuts in new directions, which has a much greater chance of breaking Moore's Law than traditional materials.
China first developed a 6-inch gallium oxide single crystal in gallium oxide materials, and then made significant progress in the field of 8-inch materials, which proves that China's gallium oxide material preparation technology is gradually maturing, and the next focus is to break through the preparation technology of 12-inch wafers.
If we have the strength to expand the production scale of 12-inch wafers, we will greatly increase the production capacity of gallium oxide material wafers, which can be widely used in more fields in the future, and will also play an important role in the development of the domestic semiconductor industry.
Now, China's achievements in the field of semiconductors continue to be reported this year, and now we have made progress in the key area of materials, so we have higher expectations for the future of China's semiconductor industry.
The good news about China has also been publicized by many foreign countries, the US sanctions are failing, as predicted by Bill Gates, the more sanctions against China, the more it can inspire China's determination to be self-reliant.
Judging from the current situation, China is indeed accelerating its research and development, and its progress in many fields is self-evident.
There is no doubt that the US blockade of Chinese companies will soon be completely lifted, which is the general trend, as long as Chinese technology companies and first-class universities work together, it is possible to build China's own semiconductor industry chain.
In my opinion, in the short term of three to five years, and the long term of eight to ten years, China will definitely be able to keep up with the pace of the West in the field of semiconductors, and now is the final stage of the speed race, as long as Chinese companies work hard, they will definitely be able to achieve results.
Are you optimistic about China's development opportunities in the semiconductor field?
