Rebirth of Northern Technology

Feng Yan's experiments during this period became more confident, and the technical development roadmaps she discussed with Cheng Yongxing were confirmed one by one. As long as the roadmap is mastered, several years of research will not be a problem.

Feng Yan has been experimenting with people for two weeks, and even Youtian, who has rushed back, has been dragged by her. These students who have gone abroad are very enthusiastic about participating in scientific research projects.

On the contrary, they are domestic students. Except for the few students who need to add a few more papers, they are not very enthusiastic about participating in the experiment. They are all trying to make up their English in preparation for the next step of going abroad.

Due to the rumors that "Colorful Science and Technology" was going to be handed over to Feng Yan, she was very handy in leading several groups to conduct experiments. In addition to her own IGBT project, even the scientific research topics in LED have improved.

The LED technology, which has been stagnant since the second half of last year, has been promoted again, and several important papers have been published.

IGBT, the main application is high-voltage and high-power switching. In this era, although the compulsory standard is very high, the market is not very big. After all, the market still needs to be cultivated.

But the relevant market in the low-voltage field has matured. But in the low-voltage field, MOSFETs are mainly the world.

The low-pressure market is actually not small. At least computer power supplies, notebook power supplies are a big market. Moreover, another market for MOSFETs, industrial switches, is also a very profitable market.

In this era, this market is completely monopolized by import manufacturers, and the profits are very high. It is also the right time for "Colorful Technology" to enter this field.

As Feng Yan progresses smoothly in related fields, another possibility will be revealed to everyone, that is, "Colorful Technology" also needs its own fab.

The main products of this fab are MOSFETs and IGBTs.

The LED market will not take off until the emergence of the white light source market, while MOSFETs and IGBTs can be seen immediately. Among other things, the power supply for that bunch of portable radio and cassette recorders is not a small market.

This idea was immediately approved by Qian Dezhi.

The independence of the big screen division led to a rapid decline in the importance of "Colorful Technology", which made him feel a little disappointed. Especially after the news that "Huge Hi-Tech" was preparing to build the first LCD screen, it became more obvious after it was confirmed.

If "Colorful Technology" can independently build a wafer fab, it will help the company's future development infinitely.

IGBT does not have high requirements on the accuracy of the wafer process, and is very close to LED, so its construction difficulty is much smaller than that of a fab for integrated circuits.

The second wafer fab of the Optoelectronics Department started construction in Bingcheng.

————————

As soon as the next semester of his senior year is coming, Cheng Yongxing is also facing the problem of graduation thesis.

Using LEDs and LCDs to do his undergraduate thesis, he always feels a little nondescript, and it is detrimental to his glorious image.

Therefore, after thinking about it, he picked up "Polycrystalline Silicon Solar Thin Film Battery".

Polycrystalline silicon solar cells, in this era, are not a tall subject, and many schools and scientific research institutions are tracking them. But this project can appear as a foreshadowing for the development of the Optoelectronics Department.

Solar cells are a very hot topic in the new world. More important than solar cells is the preparation of polysilicon.

In the field of solar cells, because the energy required for the preparation of polycrystalline silicon is much smaller than that of monocrystalline silicon, it occupies a monopoly in the field of solar energy. But more importantly, related technologies and equipment, monocrystalline silicon and polycrystalline silicon are shared.

With the advancement of the wafer industry, the production of wafers themselves will become a new bottleneck, just like sapphire.

These days, when Yuan Shuai came back, he was caught by him, and the two of them worked together to complete this undergraduate-level thesis.

In this paper, Cheng Yongxing neither created any new theories nor introduced any new innovations.

After finishing this small topic, he didn't care any more. Because his goal is a decent undergraduate thesis.
