When I am reborn, I just want to be a top student

2017 12 Month 12 Day.

This day may seem ordinary, but it is definitely an extremely important day for the domestic semiconductor industry.

Because the core technology theory of the lithography factory will be verified on this day.

If the verification is successful, it will mean that the global semiconductor industry will undergo an earth-shaking change.

ASML leads the world with EUV extreme ultraviolet lithography machines.

Although ASML's market value is not as high as that of some Internet companies, its importance is extremely extraordinary.

If the lithography factory proposed by Wang Donglai can break through ASML’s patent restrictions.

With China's capabilities, it is entirely possible to make chips very cheap.

China wants to improve its international status, strengthen its international voice, and replace the Bald Eagle Federation as the leader of the international order.

Naturally, we cannot follow the same path as the Bald Eagle Federation.

This can only be achieved through peaceful development and mutual benefit and win-win results.

To achieve this, we must make contributions in the international arena.

The most significant effect is the breakthrough in the field of technology, which has driven the development of productivity.

Therefore, the higher-ups attach so much importance to Wang Donglai’s lithography factory project and provide such strong support.

This technical verification has attracted the attention of leaders.

Relevant leaders will also be present in person.

Tang City.

High-tech Park.

This is a newly planned park with very high standards.

Although it is said that the purpose is to attract high-tech companies from all over the country to settle here, everyone knows that this place is specially set aside for Galaxy Technology.

Many of Galaxy Technology’s projects are placed here.

Just one thing can show how much Tangdu values ​​Galaxy Technology. In order to ensure the foundation stability of the lithography factory, even the original subway route was changed.

At the same time, in order to ensure convenient transportation, a special bus line was opened.

There is absolutely no doubt about the support for Galaxy Technology.

Originally, according to the above meaning, we were unwilling to make it public.

It will only be announced to the public if there are no problems with the technical verification.

If there is a problem, keep it secret to avoid the news being made public and causing adverse effects.

However, Wang Donglai refused.

First of all, the technical verification has been tested many times in advance and no problems have occurred.

Secondly, Wang Donglai knew very well that there was no problem with this plan at all.

Finally, Wang Donglai also wanted to take this opportunity to invite domestic and foreign semiconductor giants to see this scene with their own eyes.

Commonly known as rolling up your sleeves and flexing your muscles!
After all, Wang Donglai is the core figure of this project. In the face of his proposal, the superiors did not insist and agreed to do it according to Wang Donglai's idea.

As a result, there was a technology verification ceremony that shocked both home and abroad.

Quite a few people came to participate in this technology verification ceremony.

Representatives from major domestic manufacturers attended the event.

Most of the teams are led by the boss himself.

And foreign giant companies also sent people here.

The specifications are not as high as those of domestic manufacturers.

Qualcomm, Samsung, Nvidia, TJD, ASML...

Either he is the head of the China region, or a technical expert who flew directly from overseas.

Wang Donglai had no interest in talking to these people.

Just leave this kind of thing to other people and busy yourself with your own things.

2018 is coming soon. After the beginning of the year, he will carry out space rocket launch missions and will be busy.

Launching twenty rockets within a year to build an experimental space station belonging to Galaxy Technology in space, and building the space station at a higher altitude, places extremely stringent overall technical requirements.

Not only that, Galaxy Technology has such a large business, and even though it has Wa's assistance, he still has to make the final decision on the direction, so it naturally cannot be easy.

It was not until the day of technical verification that Wang Donglai rushed over from the scientific research base in Jiuquan.

"Good leadership."

After Wang Dong arrived at the command room, he greeted Minister Jia.

Logically speaking, as the highest-ranking leader present, Minister Jia should have been the last to appear and give a speech.

However, Minister Jia did not do so.

Not only did he arrive a little early, he also refused to speak.

Because he was well aware of the importance of this technical verification.

As long as there are no problems with the technical verification and it is proved that the lithography factory can indeed be built and is practical, then this will be the best news for him.

Just a speech and leadership aura are completely unimportant.

If the technical verification fails, the high-profile speech will become a problem.

Instead of doing this, it is better to just hide and wait for the results to come out.

"Academician Wang, I heard that you have been very busy recently."

"Not only has he traveled all over the world, but he has also built photolithography factories and developed space rockets. He is truly a model worker!"

Minister Jia naturally knew about Wang Donglai's schedule over the past few months.

He even knew about the research and development of the War Skull System and the Thousand-Armed Guanyin System.

It is precisely because he knows this that he took the risk and came to participate in this technical verification.

This is equivalent to standing up for Wang Donglai and expressing one's support.

Minister Jia is well aware of this.

As for why no general manager came from Tangdu City and Qin Province, it was because Galaxy Technology was already deeply bound to Tangdu and Qin Province, and there was no need to do these superficial works.

In this way, Minister Jia naturally became the highest-ranking leader present.

"Thank you for your praise, I am just doing what I can do."

Wang Donglai remained humble and responded calmly.

"At your age, you have made so many achievements and you can still remain so calm. This is rare among the younger generation. You seem more like an older generation of scientific researcher."

Minister Jia sighed with emotion and then changed the subject, saying, "Academician Wang, I am just a spectator today. You are the person in charge of this project. You will arrange the next steps. I will just wait for the good news of success."

Minister Jia's tone was very gentle, without any of the arrogance of a leader, and the meaning he revealed was extremely clear, without taking the spotlight.

Wang Donglai was not surprised and nodded immediately.

Just start giving orders according to the previous plan.

Because this is just an experimental simulation for technology verification, the equipment here has been expedited and assembled in the past few months.

In other words, this is a temporary venue.

Therefore, Wang Donglai didn’t take it too seriously.

He neither went out to make polite speeches to the visitors nor made any mobilization before the battle.

He directly ordered the staff: "Let's start!" With Wang Donglai's order.

The power switch closed immediately.

The radiation light source also gradually began to operate.

The birth of a chip goes through many processes.

Photolithography is a crucial link in chip manufacturing.

Photolithography technology was first used in 1958 and enabled the manufacture of planar transistors, which is also the most important module in the IC manufacturing process.

The process of photolithography is to spread a photoresist on the surface of a silicon wafer and then transfer the pattern on the mask to the photoresist. It is the process of temporarily "copying" a device or circuit structure onto a silicon wafer.

Photolithography accounts for almost one-third of the total silicon wafer processing cost.

Photolithography accounts for 40% to 50% of the tape-out time and determines the minimum feature size of the wafer.

Semiconductor silicon wafers go through a series of processes such as cleaning and photoresist coating before photolithography, and there are also processes such as development and cleaning after photolithography.

Naturally, it is impossible to start the technical verification this time from the very beginning.

The early materials have naturally been prepared long ago, and the single crystal silicon rods have been cut into thin slices.

In this regard, domestic monocrystalline silicon and wafers have also made certain breakthroughs.

It is worth mentioning that the one used this time is produced by Shanghai Xinsheng Semiconductor.

As for the designer Zhang Rujing, he also resigned from Shanghai Xinsheng Semiconductor this year and joined Galaxy Technology.

In addition to Zhang Rujing, many bigwigs such as Liang Song have also joined.

The joining of these bigwigs also greatly helped Wang Donglai to make breakthroughs in this area.

Otherwise, it can only be accomplished so smoothly if we develop robots, adopt a dark factory model, and use Wa to take over everything.

If this were done, the artificial intelligence that would be displayed would be too amazing, so Wang Donglai never thought about it that way.

Fortunately, with the participation of these big guys, research and development in this area has made great progress.

Part of the reason why Wang Donglai can say that technical verification can be carried out by the end of the year is because of these bigwigs.

This time, the lithography factory project attracted malicious targeting from overseas semiconductor giants, so it was transformed from being manufactured solely by Galaxy Technology to being conquered by the whole country.

In many places, it also disrupted Wang Donglai's design.

At the same time, it also saved Wang Donglai a lot of effort.

After all, no matter how backward the domestic semiconductor technology is, it is still there.

The technology in some niche areas is only slightly inferior to the international top level.

After these technologies were integrated and improved by Wang Donglai, the level they demonstrated has caught up with the international advanced level.

Just like the chip to be tested this time, it is a Surge chip independently developed by Xiaomi.

Xmi has invested a lot of money and manpower in this.

However, the results were not ideal.

Lei Jun was even ready to cancel this R&D project.

This just happened to happen.

At that time, Lei Jun was the first to stand up and express his support for Galaxy Technology and oppose the unfair cooperation of foreign semiconductor giants. Even if it was out of consideration for Xiaomi's own interests, he also owed a favor to Galaxy Technology.

Wang Donglai is a grateful person.

So, this plan was made.

Helped Lei Jun develop the Surge chip and master the 7nm process.

"Boss, this is Xiaomi's Pengpai chip. In February of this year, Xiaomi launched the Pengpai S2, which uses a 1-nanometer process and has a maximum main frequency of 28 GHz."

"However, looking at the world, this level of technology is actually quite backward."

"Currently, ASML has come a long way in developing 7nm technology, and the gap is very obvious."

"For this technical verification, I made a bold decision, which was to try the 7nm process."

"All the steps, equipment and technologies used in this technical verification are 100% domestically produced."

"The EDA design software was developed by us, as was the photoresist, the packaging design solution, and the etching technology."

"In addition, during this step, we also mastered some manufacturing details."

“For example, dielectric ion water cleaning technology, photolithography alignment technology, exposure technology, etc.”

"I can say without any modesty that if the technical verification is successful this time, it means that we have completely completed the localization of the semiconductor industry chain and have become a semiconductor powerhouse."

"Relying on our strong productivity and industrial chain integration capabilities, our products will have great cost advantages and occupy a larger market share."

Minister Jia doesn't know much about the technology in this area. After all, many of the things here are beyond the reach of experts in this field and he has never been exposed to them.

That's why Wang Donglai explained it to Minister Jia.

The working principles of lithography factories and lithography machines are roughly the same, but when it comes to the specific manufacturing process, there are big differences.

The lithography machine is small and sophisticated.

The photolithography factory was like a huge brick flying.

There is a huge gap between the two in the number of chip processes.

The latter is more than ten times the former.

And this time, Wang Donglai did not place too many wafers.

In addition to the 7nm process, 14nm, 28nm, etc. are also planned.

The main focus of a lithography factory is higher efficiency, so when doing technical verification, this must naturally be taken into consideration.

As long as the chip defect rate and final performance meet the standards this time, it can be officially announced that the lithography factory technology has been successfully verified.

at this time.

Everyone who was participating in this technical verification outside was also extremely nervous.

We were divided into two teams, domestic and foreign.

The former naturally hopes to succeed, while the latter undoubtedly hopes that the verification will fail completely.

From each other's perspective, there is nothing wrong with this.

"What a ridiculous farce!"

Jin Taiyang from Samsung suddenly sneered in the conference room.

"I noticed that your country did not adopt our technology this time. Not only did it not adopt our equipment, but it also did not adopt the technology and equipment of other countries."

“I just can’t imagine how this project got through.”

"A photolithography machine has more than 100,000 parts and components, and they are made from the most advanced technologies from all over the world."

"Bearings from Sweden, valves from France, light sources from the Bald Eagle Federation, lenses and process flow from Germany, optical technology from Sakura Country, our distribution technology, and so on."

"Each of these technologies is at the world's leading level."

"From a technical perspective, I don't think China can overcome so many technical difficulties at once in such a short period of time."

"The photolithography process is an extremely delicate job. If there is even a slight problem, the final result will not be ideal."

"I think it's very likely that we'll make this trip in vain."

Jin Taiyang stood up, his expression revealing a bit of disdain for the lithography factory, and said in a cold and sarcastic voice.

This statement immediately attracted the recognition of foreign giants and the rebuttal of domestic manufacturers. (End of this chapter)
