Wang Haijun said with emotion while taking Liu Lang to visit.

"Mr. Liu, I can't imagine that SMIC is developing so rapidly, when I came here two years ago, everything was not like this, and now I am a little reluctant to be here!"

When Wang Haijun returned from studying in the island country, he hoped to work with Liu Lang, but Liu Lang is now developing North Industries Group, and he has no energy to engage in semiconductors, so he recommended him to SMIC.

It is an indisputable fact that SMIC's response speed to chips is indeed not fast, but the country's attention to SMIC is something Wang Haijun did not expect, and a large amount of capital and equipment investment has made the chip industry develop at a speed that surprises him.

Of course, the country's semiconductor industry is not bad, in the first days of the founding of the country some technology in the forefront of the world, but sixty or seventy years of the country into a period of chaos, related industries will lag behind, fortunately in this period of time the world's semiconductor industry development is not very fast, although the gap between the two sides is very large, but not insurmountable, as long as the country makes great efforts in a short period of time can catch up.

Nowadays, the country attaches great importance to the development of the semiconductor industry, asking for money for money and people, and the management of SMIC has several real experts in charge, who understand how to develop, and at the same time resist a lot of pressure from above, which makes Wang Haijun see hope.

"Brother Wang, the power of the country is infinite, you study in the island country, you should know how Samsung Electronics developed, didn't they just use the strength of the whole country to become what they are now in just ten years? ”

"That's right, but there is still a gap between the two, Samsung's chip technology is updated very quickly, IBM, Apple have some orders, VIE is also ready to give them some orders, our speed is not able to keep up with them. ”

Wang Haijun was still a little dissatisfied.

"That's right, after all, Samsung is the pillar enterprise of South Korea, although SMIC has very high profits, but the output value is still too small, the proportion of the two companies in the national output value can not be compared at all, South Koreans dare to invest one percent of the annual output value into the Samsung Group, can our country? If that's the case, I'm afraid that other industries will be doomed, this is an objective reason, can not be changed, can change is the people of us, as long as we adhere to the kind of passion when the founding of the country, desperate to devote ourselves to the cause, I believe that the great leader said, that is, man will conquer the sky. ”

"Man wins the .........!"

Wang Haijun silently chewed this sentence, after experiencing the study of the island country, he has always felt that science and technology lie in the foundation and investment, the foundation is strong and the natural development will be smoother, and the investment will be faster, but China is lacking in both aspects, but everyone is full of passion. Xie Xide and Zhou Ming, these older generation of scientists, led to overcome one difficulty after another, some difficulties in his opinion can not be solved at all, because the country's basic manufacturing level is too low, in the simplest way, without instruments, how do you polish those precision optical components?

It is really polished little by little with human hands, especially Huang Kun, a veteran expert, his achievements have actually exceeded most people's imagination.

This day is the learning time for all employees, and regular professional training for all employees is a fixed subject of SMIC, which is generally conducted two to three times a month, and targeted training is conducted by Huang Kun, Xie Xide, Zhou Ming, Wang Haijun and professors and experts from universities.

In a big meeting, Zhou Ming was training employees on some knowledge of semiconductors.

"Let's look at this formula, the meaning is that when the electromagnetic wave hits the ion crystal and is coupled with the long optical branch, the dispersion relationship can be solved by combining the Huang Kun equation with Maxwell's equation.

This equation is known as the Huang Kun equation in the world, yes, it was discovered by Professor Huang Kun more than 30 years ago, and now it has been recognized by the international physics community, this formula has a very great significance for the transfer of light in the crystal lattice, without this equation, the development of sensors and chips will definitely not be what it is now.

What exactly does this equation mean?

In our traditional understanding, after light enters a solid, it travels at the speed of light in a vacuum divided by the dielectric constant, and then excites optical phonons or other elements through the polarization of the electric field. However, Professor Huang Kun pointed out that this is not the case, after the light enters the solid, it interacts with the element excitation that contributes to the dielectric constant, and couples together to propagate. And for the same wave vector, there will be waves of two frequencies, in which the proportion of the electromagnetic wave and mechanical vibration component and the corresponding energy of each wave varies with frequency. In particular, the frequencies of transverse and vertical element excitation are different, and between these two frequencies, electromagnetic waves cannot propagate.

At that time, this was a completely new physical picture, completely subverting the traditional concept of light waves propagating independently and not coupling with meta-excitation.......... ”

Professor Zhou Ming is teaching the students theories, of course, the students in this conference room are all university graduates, and the workers have a lot of trouble listening to this kind of class.

As he said, the Huang Kun equation was born more than 30 years ago, which caused a huge sensation in the world, laying the foundation for the future development of semiconductor sensing, and this achievement has even reached the level of the Nobel Prize.

In 47 years, Huang Kun was already a professor in the Department of Physics at the University of Edinburgh in the United Kingdom, and cooperated with Bohr, a master of physics and Nobel laureate, to co-write the "Theory of Lattice Dynamics" Monograph, if he has stayed in the UK, there is no doubt that his name will be left in the history of the Nobel Prize, but after the founding of New China, he gave up his superior life without hesitation, returned to the motherland that was poor and white, and fought for the motherland's semiconductor industry all his life.

There is no doubt that the older generation of experts in new Chinese semiconductors, such as Huang Kun, Xie Xide and Zhou Ming, will be respected as national fathers in the future.
