Rebirth of Northern Technology

Ji Xuetong has returned to the LED experiment team these days. Her TOFEL test has been completed and the results have not yet come out, but she thinks it is enough. And want to continue to improve, it is very difficult.

At present, the most important thing is to add the number of papers. This seems to be less difficult.

Ji Xuetong was originally a student in the Department of Electronics, and joined the Boy Scouts with the help of Sister Luo. She had good luck and signed her name on two papers shortly after joining.

Later, she successfully changed her major with Cheng Yongxing and became classmates with these two signed third-author papers.

But the classmates did not increase her chances of contact with the diamond king and the fifth, except for a few class activities, that one rarely appeared among the students.

Ji Xuetong is a bold girl, in other words, careless, not very patient and careful in doing things.

This makes her suffer from the results of the experiment. Up to now, she has been rubbing against the second author and the third author, and none of the first author has been found. This is rare in the Boy Scouts.

In the group, even junior students are now publishing papers and signing first authors.

After Ji Xuetong returned to the LED laboratory, she found that most of the busy people in the laboratory were schoolboys and schoolgirls.

The new laboratory has been moved to the side of the LED company's production line, with a lot more rooms. Each room does its own independent subject, and the confidentiality is greatly enhanced.

Ji Xuetong turned around and found Ye Jing and Feng Yan who were discussing in a small meeting room.

Cheng Yongxing didn't care much about LED research and development, so Ye Jing took on the main task assignment, especially the LED laboratory.

During this time, she also ran on both ends. Not long after returning to the company from Spring City, she met two acquaintances.

The first is Feng Yan, who just came back from abroad.

Cheng Yongxing had already said hello first. Feng Yan will take over the scientific research department of the LED company in the future.

Compared with Feng Yan, Ye Jing is only temporarily helping here, and after a while, she will completely return to Spring City. This meeting can be regarded as a handover.

Ye Jing is very polite to these former testing students. According to Cheng Yongxing's temper, if this group of people hadn't run out, it would not be the second echelon's turn.

So the two of them have been discussing the next tasks of the research team together.

Colorful technology needs to face the LED retail market, and some things that have not been paid attention to before have also been paid attention to.

For example, cost.

There are two aspects to cost, one is the cost of raw materials, and the other is the yield. These parameters and indicators that were not particularly concerned during the monopoly period have all been taken seriously.

In addition, with the gradual opening of the LED light source market, the proportion of white LEDs in the company's products will also increase. Correspondingly, the company's scientific research focus will gradually change.

As Ye Jing graduates, the Boy Scouts will gradually split up.

Some members of the Boy Scouts will face graduation. Some of these members will be transformed into full-time researchers in Duohua Company.

The remaining members of the Boy Scouts in school are diverted. Although some of them are still in school, they are treated as full-time employees and begin to receive salaries.

The other part degenerates into an amateur research group and will gradually be marginalized.

The stage of relying on school students for research and development has passed. The Boy Scouts, as an organization, ceased to exist.

Ji Xuetong's request was resolved by talking to the two strong women.

Her purpose is the first author's paper, not really an experiment or a project. "Colorful Technology" has a lot of resources. For a large number of unpublished papers, just find one that is close to decryption and ask her to sign the name.

The Optoelectronics Department has established absolute authority in the LED and LCD industries. As long as the papers submitted by Optoelectronics, they are unimpeded in various international journals.

Feng Yan was forced to come back this time.

She spent half a year in school comfortably, leisurely, and very happy. During this period of time, her social circle has expanded a lot, and she is very popular wherever she goes.

Not only has her value not decreased during this period, but she has also moved higher and higher, and has established contacts with many companies. If she wants to do a project, a lot of funds and projects will flood in. This is the opposite of Hao Yunli's quest for projects and funds everywhere.

Since her life was very comfortable, she wanted to just hang on like this. But with Hao Yunli's big paper, her good days suddenly ended.

Hao Yunli published a paper in SCIENCE that shocked the world, at least it shocked the Edward Lab.

Hao Yunli had an opportunity to be published in a top CNS journal before, but Professor Wang gave up in order to grab time.

This time she finally got her wish.

Moreover, this paper is not an ordinary top-level paper. According to Professor Edward's evaluation, this is a paper with Nobel Prize potential!

This has caused many laboratories and institutions that repeatedly bargained with Hao Yunli some time ago regretted it.

The Edward Lab also had the opportunity to keep Hao Yunli. Although Professor Edward doesn't say anything now, his eyes on Feng Yan have changed. Not only him, everyone put their hopes on Feng Yan.

With the same background and similar scientific research experience, Feng Yan even has the support of the industry. Everyone was dissatisfied with her inaction for several months.

Hao Yunli has become a legend in the University of Pittsburgh and Edward Lab. Some of her past achievements, such as the total number of papers she published, are also talked about by everyone.

Correspondingly, the expectations of Feng Yan have also been raised by more than one grade.

Feng Yan couldn't resist this pressure and simply returned to Bingcheng.

After discussing with Ye Jing, she went to Cheng Yongxing. But as soon as the two met, she was assigned a new task.

IGBT. InsulatedGateBipolarTransistor, insulated gate bipolar transistor, has a wide range of applications, including frequency conversion, voltage transformation, switching power supply, etc. In later generations, its application scenarios include rail transit, electric vehicles, etc.

In 1992, IGBT was not a new concept.

In 1979, MOS gate power switching devices appeared as the pioneer of the IGBT concept.

As soon as this technology appeared, it attracted the attention of semiconductor manufacturers around the world. Many companies invented this device almost simultaneously and independently, and at the beginning, each company called it differently.

With the passage of time, IGBT technology has matured day by day, some new manufacturing processes (DMOS) have been adopted, and various structures have been tested by various manufacturers and have achieved some achievements.

As time entered the 1990s, with the gradual maturity of large-scale integrated circuit technology, some processes used in semiconductor production will soon be introduced by IGBT researchers.

The vertical structure (3D) of silicon chips has brought huge changes to the design of IGBTs.

In the mid-1990s, there have been many technological breakthroughs in the structure of the IGBT.

Among the more famous ones are NPT-IGBT (transmissive) and LPT-IGBT (weak penetration). In this wave, the most important technology is CSTBT. So far, the fifth-generation IGBGT is officially mature.

Cheng Yongxing has been staring at this technical direction for a long time, because its economic value is very large, not even weaker than LED, but it has been suffering from no staff.

With the passage of time, the window for the introduction of these technologies is slowly closing.

Therefore, as soon as Feng Yan came back, he was immediately arrested.
