Still In Bluestar, How Did The Rabbit Start the Starcraft?

On March 10, after the coordination of all parties, Li Qiu immediately divided the group according to the lithography machine assembly technology obtained by his own analysis.

The researchers who joined Li Qiu's domestic lithography machine project this time are three academicians from the Academy of Engineering from the top optoelectronic research institutes in China alone.

And the three academicians of the Academy of Engineering are not just as simple as representing three people. Behind them, there is the scientific research force of their entire group, such as several professors and associate professors, researchers, postdoctoral fellows, doctoral students...

The scientific research team represented by an academician of the Academy of Engineering alone exceeds nearly 100 people.

Coupled with various other optoelectronic experts and engineers, this lithography machine project even gathered tens of thousands of related talents in Longguo.

However, the lithography machine alone has more than 10 functional parts, more than 3,000 lines, and dozens of subsystems, so although these tens of thousands of expert engineers may sound like a lot, but for a large-scale project like a lithography machine, it is actually in the Even if you have enough people.

The functional parts of Li Qiugen's lithography machine parts and the parts that these expert engineers are good at are divided into 400 assembly groups, who are then responsible for their independent module assembly tasks.

Of course, when the assembly task of very few groups reaches a bottleneck or an unsolvable problem, Li Qiu will also provide them with corresponding ideas.

As for Li Qiu himself, he began to lead the project team of the 019 Institute to conquer the core parts of the lithography machine.

Longguo is a big industrial country, and most of the more than 100,000 parts involved in the lithography machine can be produced in Longguo.

However, regarding the core optical lens, optical light source, workpiece table, and high numerical aperture lens and other more than 1,000 components, Longguo has no technology and no factories and enterprises to produce.

These require Li Qiu to lead the team to overcome the difficulties.

When Li Qiu was busy, as a cooperative unit of 1-nanometer military-grade chips, the Second Academy of Aeronautics also began to upgrade its own military chip production process.

In order to ensure that as long as Li Qiu's 920 has completed the 1-nanometer lithography machine and chip drawings, the second aviation institute can immediately start chip production.

On August 10th, a full five months had passed since the project was first developed.

With the efforts of tens of thousands of people, the 400 independent organizational module groups divided by Li Qiu finally succeeded and completed their respective tasks.

During these five months, Li Qiu led the project team of the 019 Academy to successfully develop the most difficult core parts. Li Qiu also designed the most important PTZ algorithm for the lithography machine to manufacture and etch chips.

Windmill Country, or in other words, all lithography machines now generally adopt the design concept of dual-head synchronization. After obtaining the technical analysis in the game, Li Qiu resolutely adopted the design of eight-head synchronization in order to improve the working accuracy of the lithography machine. Way.

The so-called dual-head synchronization is to synchronize the two worktables inside the lithography machine, and the synchronization error between the two worktables must be less than 5 nanometers.

Although the design of Li Qiu's eight gimbal allows the lithography machine to maximize the accuracy when entering the etching, in the traditional sense, the synchronous operation of the eight worktables also increases the error.

In order to solve this problem, Li Qiu directly used eight extremely precise gyroscopes to achieve the synchronization of the eight gimbal.

He designed an independent control code for each gimbal, and added eight codes to operate together, and used a precise algorithm to control the gyroscope, which realized the problem of solving the error.

When all these problems were solved, the 1nm lithography machine finally entered the final assembly link.

That is, 400 individual modules are assembled into the final overall lithography machine.

However, at this time, this project will no longer be carried out in the 019 Institute. The entire lithography machine weighs more than 200 tons. After the final assembly, it will be put into production directly (ccca) instead of dismantling it and re-organizing it in the factory.

Next, the entire project team will be collectively transferred to a large newly built factory in River Norte, where the final assembly will be completed.

On August 13, all the R&D and engineering assembly personnel of the entire project team came to the large dust-free workshop in the North River semiconductor chip production factory.

Originally, the annual power consumption of a lithography machine was also more than 2 billion kWh. The construction of this factory site is a very test of power supply.

But now the whole country of Longguo has achieved nuclear fusion power supply, so there is no such worry at all.

On August 14, the overall assembly of the world's first 1-nanometer precision lithography machine officially began.

This process will last at least 20 days to a month, and it is also the most tiring stage.

But at this point in the project, the tens of thousands of people on the project team were all very excited.

All the staff of the entire project team are suffocating in their hearts, vowing to bring out the domestic lithography machine.

"Chen Lao, Liu Lao, Zhu Lao, I have to ask you three to work hard for another month!"

In front of the monitoring station in the main control room, Li Qiu said apologetically as he looked at the three academicians of the Academy of Engineering.

This project is based on the progress of the military project. The speed of the project is much faster than that of ordinary scientific research projects. During this period, many young people cannot bear it, let alone the three old academicians.

"General Manager Li is serious. You have far more burdens and difficulties to overcome than us."

"And being able to develop a domestic lithography machine to a world-class level, or even a world-leading level, is a lifetime dream of us optoelectronic researchers. 99

"We would also like to thank Chief Engineer Li who is about to realize our dream!

Academician Chen responded to Li Qiu.

"That's right, we and the team we brought in this short half-year period really opened our eyes. 35

"Under your guidance, Mr. Li, during this period, we have solved more difficult problems on the high-precision lithography machine than in the previous decades. 35

"I am very confident in this final assembly link, we will definitely succeed!

Academician Liu nodded and said with great agreement.

"Then the four of us will each be responsible for one area, monitor the assembly group data in each area, and review the actual operation report in each area once a day."

Li Qiu said.

Now that the final assembly process has begun, the lithography machine is a machine composed of more than 100,000 parts, and each screw in the final assembly process has a detailed standard process.

Therefore, in this link, they need to keep their eyes on them all the time. If there is any non-standard place in each area, the work of the day must be scrapped and restarted.

Only with high requirements and high precision, can the success of the lithography machine assembly be achieved in the end!

On September 5, after more than 20 days of assembly work, the general assembly work of the project team led by Li Qiu was finally completed.

The next step is to carry out the final power-on simulation stage to check the true accuracy of the lithography machine after successful assembly.

[The estimated remaining time for technical analysis of the suspended battleship: 17353 days!]

After such a long time, the technical analysis of the suspended battleship is almost halfway through.

But it took so much time for just a 1-nanometer military-grade chip, which was something Li Qiu had not thought of before.

Fortunately, Li Qiu has already designed a 1-nanometer chip. As long as the lithography machine completes the power-on simulation and successfully completes the etching of the 1-nanometer chip, the project is officially completed.

After two days of repairs, Li Qiu finally decided to conduct the final power-on simulation test.

After the two-day break, all the staff of the entire project team were waiting for this moment with a full spirit and an extremely nervous mood.

"It's finally here. If this project can be successful and I can see the success of the domestic 1-nanometer chip, even if I die, I will have no regrets in my life!

Chen Lao suddenly burst into tears, took out a handkerchief and touched the corner of his eyes.

It took seven months to assemble the lithography machine with an estimated precision of 1 nanometer. He always felt that he was living in a dream during this time.

"Yeah, seeing that people from all walks of life are contributing to the country and making remarkable achievements."

"How many times has the Institute of Optoelectronics, which developed domestic lithography machines, made the Chinese people and national enterprises feel the deep helplessness and despair? 35

"I am willing to trade my life for the success of this project!"

Academician Liu also said with some excitement.

And just when they were full of emotion, news suddenly came from the front to the general control room:

"Report to the commander-in-chief, all parts are tested normally, the power supply is up to standard, and the lithography machine can be powered on at any time!"

"Report to the commander-in-chief, the silicon wafer has been prepared, and the ASTM test purity is 6 9!""

"Report……"

At this moment, everything is ready.

"Power up, 1nm chip, test!"

At nine o'clock in the morning, Li Qiu firmly gave the order.

Although usually high-precision lithography will be tested with low-precision chip design solutions first, because the old chip design solutions will be more mature.

But Li Qiu is extremely confident in this lithography machine, which has been devoted to seven months of hard work.

For the first power-on simulation, the 1-nanometer chip design solution with the highest accuracy in the world and at least ten years ahead of the world was directly used for testing.

After Li Qiu issued an order and the lithography machine was officially running, everyone in the entire factory clenched their fists tightly, waiting for the result.

And this stop is more than five hours!

During this period, except for the sound of machines running, the entire factory did not even have the sound of anyone talking.

Everyone's heart was extremely nervous at this moment.

Until two o'clock in the afternoon, the first domestically produced 1-nanometer chip wafer was successfully trial-manufactured.

"Quick, send it to the middle test!"

Academician Chen covered his heart a little too excitedly and said to the engineer on site.

Whether the various circuits etched out of the chip are successful or not can not be judged by the human eye, and the results must be known through relevant tests.

At this time, everyone's heart felt like it was almost jumping to the throat.

An hour later, the good news came again, the 1nm chip wafer was successfully tested!

This means that the 1nm lithography machine is successful!

At the same time, it also indicates that Longguo will soon have a domestic chip with a precision of 1 nanometer!

"Success!"

I don't know who made the first hysterical roar, and then the entire factory was directly drowned out by the roar.

Everyone is using this method to vent the uncontrollable excitement in their hearts, as well as the extremely high pressure during this period of time!

"Success?"

"Li Qiu, I've only been on a business trip for more than half a year, yet you actually succeeded in making a 1-nanometer chip for our 019 Institute?"

At this time, the hospital leaders and Lieutenant General Wang Hang rushed to the factory belatedly, covered their ears and came to the general control room, looking at Li Qiu in disbelief.
