The Science Fiction World of Xueba - Chapter 458

Pang Xuelin quietly entered Xu Baiqing’s office.

Xu Baiqing was wearing reading glasses and was writing something at his desk.

Pang Xuelin coughed hard.

Xu Baiqing raised his head and looked at Pang Xuelin. He immediately smiled and said: “You are a little guy, and finally you are willing to come back. I haven’t seen you staying at school for another day after the start of the school. You won’t leave this time!”

Pang Xuelin said with a smile: “I will not leave until the winter vacation this time!”

Xu Baiqing knew that Pang Xuelin ’s subtext was that he had to leave next year, and he could n’t help but sigh: “You see how good our school ’s style of study is because your kid is famous, and now many students discuss your entrepreneurial history every day, and I wish I could become You are like this. “

Pang Xuelin laughed and said: “Senior man, this is not to be blamed on me. You can see that I haven’t stolen or robbed me. The start-up capital was still working hard to help Warwick, and the development of CVD is not a simple matter. It ’s not just me who blows up a video decoding chip. At present, no one except me can get it. “

Of course, Xu Baiqing also knew the truth here, saying: “Don’t tell me this, you and the students in the school, you happen to be back, I will arrange it in two days, you will do two reports in the school, Now you can be regarded as a role model for students at Lanta University, which is beyond reason. “

Pang Xuelin had no choice but to cry with a smile.

After a moment of contemplation, Pang Xuelin said again: “Senior man, when I come back this time, I want to ask the school for help.”

“what’s up?”

Xu Baiqing looked up at Pang Xuelin Road.

Pang Xuelin said: “I want to do integrated circuits, but now there are not many talent reserves in this area in China. I hope you will introduce it to me.”

“Engaged in integrated circuits?”

Xu Baiqing couldn’t help but widen his eyes.

China’s integrated circuit industry, not to mention this era, even in the real world, is still far behind Western countries.

Of course, in the real world, Pang Xuelin has found a path to overtake in a corner.

In the Qiantang laboratory, Li Changqing is leading a team to develop carbon nanotube chips, and has already achieved considerable results.

However, in this world, the research of carbon nanomaterials has just started, and there are many basic problems that need to be solved. Therefore, Pang Xuelin can only start with silicon-based chips to defeat Western countries in an upright manner.

In fact, historically, it is not too late for the development of China’s integrated circuit industry.

In 1947, Bell Labs of the United States invented semiconductor point contact transistors, and in 1949 developed germanium alloy transistors.

The Institute of Applied Physics of the Chinese Academy of Sciences also developed a germanium alloy transistor in 1956.

In 1954, the United States developed a silicon alloy transistor.

China Beijing Electron Tube Factory also developed silicon alloy transistors in 1958.

In 1958, Texas Instruments and Fairchild respectively developed semiconductor monolithic integrated circuits. In 1959, the United States invented planar lithography technology and successfully developed planar diffusion transistors. In 1960, the United States adopted planar technology to develop integrated circuits, and has since embarked on a mass production road.

The Institute of Semiconductors of the Chinese Academy of Sciences also developed planar tubes in 1963, and several units are also developing planar tubes. Immediately afterwards, a number of research institutes in China developed integrated circuits in 1965, including the Institute of Semiconductors of the Chinese Academy of Sciences, Hebei Semiconductor Institute (abbreviated as 13 institutes), Beijing Institute of Radio Technology (abbreviated as Shahe Institute of Devices), etc. In December 1965, 13 institutes first identified a DTL type digital circuit using dielectric isolation at the product appraisal meeting.

After the research unit, the factory also developed integrated circuits on the basis of the production of planar transistors. The north is the Beijing Electron Tube Factory (774 Factory), and the south is the Shanghai No. 5 Component Factory. The latter held a product appraisal meeting at the end of 1966 and identified a TTL digital circuit using the internationally common PN junction isolation technology.

It can be seen from this that in the 1950s and 1960s, in the initial stage of semiconductor transistors and integrated circuits, China was only 4 to 7 years away from the United States, and the difference was not very far.

However, for well-known reasons, by the 1970s, the gap between the development of the integrated circuit industry between China and the United States began to widen.

Throughout the 1970s, China could only produce all kinds of small-scale integrated circuits (including digital circuits and linear circuits) on its own to supply various industrial departments and research institutes of the Academy of Sciences to develop and produce various electronic complete machines, including industrial applications and defense military demand.

It was not until 1978 that Shanghai’s 878 factory built China’s first 2-inch line, lagging the world for 12 years, and in 1980 it built China’s first 3-inch line, lagging the world for 8 years.

In the field of computer chips, China has made a strategic mistake. It did not list computer chips separately for development, but regarded them as a common link in the entire computer industry chain.

That is, every time a computer is developed, China will simultaneously develop a chip to match it.

In this way, on the one hand, it caused a great waste of R & D resources. On the other hand, because of the low computer output in that era and the limited demand for chips, it has dragged down the development of the entire integrated circuit industry.

In the 1980s, China began to shift from self-reliance to technology introduction.

However, whether it was the 742 factory or the later Huayue Company, the development was not successful.

By the end of the 1980s, China Electronics News created a column discussion: Where did China’s integrated circuits go?

After experts, professors and government officials published articles and discussed extensively, the Chinese integrated circuit industry began to move towards Sino-foreign joint ventures, so there were 908 projects and 909 projects.

In February 1990, the Ministry of Machinery and Electronics Industry recruited personnel from various units to prepare proposals for 1 micron integrated circuit projects. The project was established in August of that year and was named “908 Project”.

The 908 project was undertaken by the newly established Huajing Group Company.

However, due to project approval and funding availability, it was not completed until the end of 1997, which lasted 8 years.

Huajing introduced a 6-inch chip production line from Lucent Corporation of the United States and circulated two products of 0.9 micron CMOS process. It passed the acceptance of the external contract until January 1998, which was 13 years behind the United States.

The 909 project was proposed by the Ministry of Electronics Industry in 1995, and it plans to invest 10 billion yuan to build an 8-inch 0.5-micron chip production line ~ www.mtlnovel.com ~ a joint venture between Huahong Microelectronics and NEC in 1999. On February 23, the ultra-large scale integrated circuit chip production line of the 909 project was officially launched. This is China’s first 8-inch chip production line, 11 years behind the world.

…

In fact, the reason why these attempts are unsuccessful has a great relationship with the high capital, high technology and high talent threshold of the integrated circuit industry.

Especially in the era when China’s economy is still underdeveloped, it is basically impossible to spend big money on big things.

Although Xu Baiqing is not engaged in semiconductors, as a condensed matter physicist, he is well aware of the current plight of China’s integrated circuit industry.

Not to mention, just now, there are not many universities in China that offer microelectronics majors. The number of graduates per year is only two or three hundred, which includes those who choose to go abroad.

With such a weak talent pool, how can China’s integrated circuit industry develop?
