Pang Xuelin quietly entered Xu Baiqing's office.

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

Pang Xuelin coughed hard twice.

Xu Baiqing raised his head at this time, and when he saw that it was Pang Xuelin, he immediately smiled and said: "You little guy, you are finally willing to come back, I haven't seen you stay in school for one more day after the start of school, this time you won't leave!" ”

Pang Xuelin said with a smile: "This time I will stay until the winter vacation, and I won't leave within the year!" ”

Xu Baiqing knew that Pang Xuelin's subtext was that he would have to leave next year, so he couldn't help but sigh and said: "You see how good our school is, just because you became famous, many students now discuss your entrepreneurial history every day, and they can't wait to be like you." ”

Pang Xuelin laughed and said: "Old man, I can't blame me, you see that I didn't steal or rob, the start-up capital is still earned by working hard to help Warwick, and the research and development of CVD is not a simple matter, a single video decoding chip, not I blow it, at present, no one in China can do it except me." ”

Of course, Xu Baiqing also knew the Tao in this, and said: "Don't tell me this, you and those classmates in the school said to go, it just so happened that you came back, I will arrange it in two days, you will make two reports in the school, and now you can be regarded as a student model of Lanzhou University, which can not be shirked." ”

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

After pondering for a moment, Pang Xuelin said again: "Old man, I came back this time because I wanted to ask the school for help." ”

"What's the matter?"

Xu Baiqing looked up at Pang Xuelin and said.

Pang Xuelin said: "I want to engage in integrated circuits, but now there are not many domestic talent reserves in this area, I hope you can help me introduce it." ”

"Engage in integrated circuits?"

Xu Baiqing's eyes couldn't help but widen.

China's integrated circuit industry, not to mention this era, even in the real world, is 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 the team to develop carbon nanotube chips, and has achieved great results.

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

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

In 1947, Bell Labs invented the semiconductor point contact transistor, and in 1949, the germanium alloy transistor was developed.

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.

The Beijing Electron Tube Factory in China also developed a silicon alloy transistor in 1958.

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

The Institute of Semiconductors of the Chinese Academy of Sciences also developed a flat tube in 1963, and many units are also developing flat tubes. Subsequently, a number of research units in China developed integrated circuits in 1965, including the Institute of Semiconductors of the Chinese Academy of Sciences, the Hebei Institute of Semiconductors (referred to as 13), the Beijing Institute of Radio Technology (referred to as the Shahe Institute of Devices), etc., and in December 1965, the 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 its own integrated circuits on the basis of the production of planar transistors. Beijing Electron Tube Factory (774 Factory) in the north and Shanghai Component No. 5 Factory in the south, the latter held a product appraisal meeting at the end of 1966 to identify a TTL digital circuit using the internationally accepted PN junction isolation technology.

It can be seen that in the fifties and sixties of the last century, in the initial stage of semiconductor transistors and integrated circuits, China was only 4~7 years away from the United States, and the difference was not very far.

However, due to well-known reasons, in the seventies of the last century, the gap between China and the United States in the development of the integrated circuit industry began to widen.

Throughout the 70s, China could only produce all kinds of small-scale integrated circuits (including digital circuits and linear circuits) on its own, and supply various industrial departments and research institutes of the Academy of Sciences to develop and produce various electronic complete machines, including industrial applications and national defense and military needs.

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

In the field of computer chips, China has made a strategic mistake by not listing computer chips separately for development, but treating them as an ordinary part of 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, and on the other hand, due to the low output of computers in that era, the demand for chips was limited, which dragged down the development of the entire integrated circuit industry.

In the 80s, China began to shift from self-reliance to technology import.

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

At the end of the 80s, China Electronics News opened a column to discuss: Where are China's integrated circuits going?

After experts, professors and government officials published a wide range of articles and discussions, China's 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 transferred personnel from various units to compile the 1-micron integrated circuit project proposal materials, and the project was approved in August of that year and named "908 Project".

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

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

Huajing introduced a 6-inch chip production line from Lucent Company of the United States, and circulated two products with 0.9 micron CMOS process, which only passed the acceptance of foreign contracts in 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 was ready to invest 10 billion yuan to build an 8-inch 0.5-micron chip production line.

On February 23, 1999, the 909 project VLSI chip production line was completed and officially put into production. This is China's first 8-inch chip production line, lagging behind the world for 11 years.

……

In essence, the reason why these attempts were unsuccessful has a lot to do with the high capital, high technology, and high talent threshold of the integrated circuit industry.

Especially in the era when China's economy was still underdeveloped, it was basically impossible to do big things with little money.

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

Not to mention, at present, there are not many colleges and universities in China that offer microelectronics majors, and there are only two or three hundred graduates every year, which also includes those who choose to go abroad.

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