Chapter 414 The gap in the electronics industry is not big
Just as the chip industry in Western countries was gradually emerging, the country was in chaos during this period. Although the country did not give up research work, those talents were no longer the original group, because
Most of the older experts were sent down below to "farm fields and herd cattle."
It was from this period that the country's semiconductor industry began to stagnate. In the early days of reform and opening up, the country was still trying to revive the semiconductor industry. However, since the relevant technology had lagged behind foreign countries at this time, the fastest way to improve was to
Foreign technology was introduced, and this set of equipment at Jiangnan Radio Factory was introduced during this period.
However, the country soon discovered that the foreign exchange in its pocket was really pitiful. Once this technology was introduced, it could not introduce other technologies. At this time, the country made steelmaking and ironmaking the primary goal of the national industry, and only maintained the expansion of steel.
This project cost the island country five billion U.S. dollars, almost depleting its foreign exchange reserves over the years, and the high-investment semiconductor industry was abandoned.
Zhou Ming briefly talked about the country's development in lithography machine technology. Everyone else listened carefully and felt sorry for it. But Liu Lang was shocked when he heard it. It turns out that the country had such a period.
"brilliant".
"I didn't expect that the country had already manufactured lithography machines more than 20 years ago. If we continue to research, after 30 years, I am afraid that Chinese companies will be the only companies in the world that can manufacture lithography machines."
Thirty years later, the Chinese people always think that the country's chip technology is too backward, and money has been spent, but it still cannot improve. When the United States gets angry, the country becomes confused, but now, this is definitely not the case.
The foundation of the country's semiconductor industry is indeed strong. At least in the 1960s and 1970s, it was definitely ranked among the world's top level. Throughout the 1970s, the country was in a state of chaos, and the semiconductor industry stagnated. However, foreign technology advanced by leaps and bounds, and the gap between the two was quickly eliminated.
Pull back, it is now 1985, and the technological gap between China and foreign countries is not too big. According to Liu Lang's estimation, there is only about one generation. Unlike industrial machine tools, even second- and third-rate equipment from Germany is much better when bought domestically.
You are a generation ahead.
The gap between China and foreign countries in integrated circuits should have been completely widened in the mid-to-late 1980s, because this period was a stage of rapid development of the computer industry, and the manufacturing of integrated circuits began to follow "Moore's Law", that is, every ten years
In a few months, technology will be completely updated to a new generation, starting from the 1990s
From the early 1990s to the first ten years of the new century, the development of the integrated circuit industry has been like a big explosion in the past two decades. The process technology has also developed from a few microns to more than ten nanometers. China has been completely left behind and wants to develop again.
Trying to catch up with the distance that has fallen in the past twenty years is just as difficult as climbing to the sky.
This is a very interesting phenomenon. It symbolizes the machine tool industry of traditional industrial manufacturing. The country lags far behind foreign countries. Even Liu Lang is so smart, he feels that even if China catches up from now on, it can catch up with the island country in 20 to 30 years.
Advanced countries like the United States and Germany are very good. However, as the chip industry of the future high-tech industry, the country has started to develop very early, and even now, the gap with Western developed countries in this regard is not too big.
.
The reason Liu Lang also figured it out is that the development time of the semiconductor industry is much shorter than that of traditional industries, and there are not many talents in related fields in the West. At least in the 1950s, China's group of experts who returned from overseas
There may not necessarily be much gap than the other party, and it may even surpass the other party in some aspects. In addition, the potential of the computer industry has not been fully realized in recent years, and the development of semiconductor applications seems to have entered a bottleneck.
The 85th Five-Year Plan is a special time period. Apple's personal computer has just taken shape. Microsoft and Intel have not yet shown their claws. The chip industry seems to be silent, but this is only a superficial phenomenon, like a dormant computer.
Like a volcano, once it erupts it is unstoppable.
Fortunately, Liu Lang has appeared now. Not to mention what the future holds, at least everyone has come together to develop chips. As long as these people can persist, and as long as the country can pay attention to it, the country's chip industry will definitely be better than Liu Lang's in ten years.
His previous life was much stronger, at least it wouldn’t make Western countries pinch their necks and choke them.
Of course, many people still don't realize how big an impact the chip industry will have in the future world. Their current task is to manufacture Wanhe's chips and complete the tasks assigned by the country.
Wang Haijun is very familiar with this set of wafer equipment and knows every major component. However, when it comes to technology, he is far behind Zhou Ming. As a national expert who has witnessed the development of the national semiconductor industry from scratch, he is familiar with these dense,
The integrated circuit board that makes most people dizzy is really closer than a relative. He and Xiong Huaizhi are the same people. They are more important to their careers than their own lives, so when the equipment was dismantled, he became the protagonist.
, everyone will follow him.
"Our country's first engraving machine... Oh, Westerners call it a photolithography machine. This term is more appropriate...
Twenty years ago, we used 436nm g-line and 365nm i-line produced by mercury lamps as engraving light sources, which could meet the needs of integrated circuit production in 0.8-0.35 micron processes.
And our early... photolithography machines used contact engraving, that is, the mask was attached to the silicon wafer for engraving. Many integrated circuits inside our country's Dongfanghong satellite were burned in this way.
Yes, but this kind of engraving is easy to cause pollution and the mask life is short."
Zhou Ming looked at it carefully and muttered to himself. Obviously, the recorder in front of him no longer uses mercury lamps, but it seems that the specific light source needs to be studied.
"Professor Zhou, lithography machines now use krypton fluoride excimer lasers as light sources, which can increase the minimum process node to the level of 0.1 micron. This equipment uses scanning projection in the lithography process.
Type lithography is also a common type of lithography machine nowadays. The light source passes through the mask and is exposed on the silicon wafer in a scanning manner after being adjusted and compensated by the optical lens."
Chengxian appeared at the scene at this time. Although he is a chip designer, he also knows a lot about wafer equipment. He also went to Wanwan to train the workers there a few years ago.
Chengxian "admired" Liu Lang very much. In his eyes, Liu Lang was a giant of the era, so he was now determined to learn from Liu Lang, and naturally he would not hide this skill secretly.
"Excimer laser as a light source? It's really amazing. We only heard about this laser technology in textbooks 20 years ago. The Soviet Union seemed to be conducting research at that time. Our country's laser technology is actually also very advanced. As early as the 20th century
We started researching it years ago, but it was only used in national defense. Now Americans have applied it in production. I admire it, I admire it!"
