Chapter 119 Huaxia's Chip Disaster

While the scientists were assembling the lithography machine nervously and orderly, Lu Xin had already returned to Yanggang District.

There are 10 parts in the lithography machine. Although most of them are modular groups, they only need to be assembled like building blocks, but it takes time, at least [-] days!

In fact, if Sean is allowed to assemble it alone, it can be assembled in at most 3 days.

Because the assembly method of these parts has long been deeply engraved in Sean's mind, and it can work without sleep or rest.

However, in order not to reveal his flaws, Sean needs to eat, drink, and rest like a normal human being, and then expel the crushed food in the stomach through the excretory hole when he goes to the toilet.

In the process, Sean has to take the trouble to guide some young engineers, telling them how to use the lithography machine and how to troubleshoot it in time.

These young engineers trained by Guo Jia are all geniuses in the field of lithography machines, and they all know lithography machines very well.

However, the lithography machine they know is a 28nm process lithography machine, and there is a big gap between the two, and this time the 5nm lithography machine is EUV extreme ultraviolet lithography, which is different from the DUV light source of ordinary lithography machines.

And after the lithography machine is assembled, Sean will also guide those engineers to trial production.

Only when a 5nm chip is actually produced, can Sean retire successfully!

So it will take three months at the fastest, and it may take four to five months if it is slow!
However, Lu Xin, who returned to Yanggang District, did not relax, and important figures would come to him every two days.

As a result, he could only go to Cyberworld during this period of time, only at night.

But since he decided to bring the lithography machine to the main world Huaxia, he had already expected this.

He was also mentally prepared for this.

You can't have your cake and eat it too.

Fortunately, when those big shots come, they usually bring only one driver, so they don't need to mobilize so many teachers.

November 3th, at two o'clock in the afternoon.

"Lu Xin, who is that man who came today? He looks so majestic!"

In the yard, Tong Xin gnawed on an apple and asked.

Lu Xin casually said a name.

Hearing this, Tong Xin was surprised and said, "No wonder it looks so powerful!" Lu Xin, how do you know such a big man? "

Lu Xin deliberately threatened her and said, "You can't tell, and you can't ask, maybe you will be invited to drink tea."

Tong Xin stuck out her tongue in fright, waved her hand and said, "I won't ask any more, and neither should you."

"Ok!"

Lu Xin threw away the cigarette in his hand and said, "Let's go to the Golden Harbor to see how the house is going."

He bought the Linjiang unfinished villa building in the southwest of the university town and redeveloped it.

He is going to build a garden villa in a Jiangnan water town, with pavilions, pavilions, pavilions and gardens.

Of course, this is only the exterior. The interior of the house still needs to combine Chinese and Western styles. It must be modern and simple, but also ancient and down-to-earth.
The main structure of the house here has been completed, but the previous developer's capital chain was broken and was seized by the court. It took more than a year and nearly two years to go through the process, and it was just auctioned a year ago.

But because the price is too high, and the national housing prices and land prices have reached their peak, all of which are in sideways trading, no one dares to invest money in this field at this time.

So it failed two auctions, and he finally bought it at a reserve price of 1.25 million.

In addition to Wei Jin, Lu Xin and the four went to Golden Harbor in the bodyguard's car.

……

After inspecting the construction site, everyone went to a high-end private club to drink tea, take a shower, and listen to a musical.

The owner of this club is very capable, and will invite powerful singers to sing every now and then.

Today's invitation is Deng Ziqi, a young singer who Lu Xin likes very much.

I came over and sang three songs, one "Bubble", one "You Are Not Really Happy", and one "Like You".

"Looking at the lonely evening light is that sad memory..."

Following Deng Ziqi's singing, the audience listening to the song also hummed along.

Wei Jin also liked Deng Ziqi very much, and even ran to him and sang with Deng Ziqi.

Deng Ziqi took her to the stage to sing together.

Unexpectedly, Wei Jin sang very well, with a unique sense of innocence, which is very recognizable.

It was the first time Lu Xin heard Wei Jin sing, and his eyes lit up.

"I hope you will know now, it is my sincere voice..."

On the stage, Deng Ziqi took Wei Jin's hand and raised it high, then followed closely to look at the audience and said, "Let's come together... I like you, your eyes are charming, and your laughter is even more charming..."

"Ok?"

Lu Xin froze for a moment, and found that besides the singing voices of the two people on the stage, there was a third voice singing beside his ears, so he turned his head to look for it.

As a result, it happened to meet Tong Xin's bright eyes.

Seeing Lu Xin looking at her, Tong Xin not only did not avoid his eyes, but instead looked at him firmly with a pair of beautiful eyes, and sang loudly with her pink mouth: "Maybe again, caress you..."

Just as Lu Xin was about to turn his head, Tong Xin couldn't help it anymore, reached out to hug his head, and quickly kissed him on the face.

After letting go of her hand, Tong Xin's delicate face was already flushed, and even her ears were flushed.

"Lu Xin, I like you!"

If it weren't for Lu Xin's keen five senses now, ordinary people wouldn't be able to hear them. He leaned over and smiled in Tong Xin's hot ear, "Cousin, why didn't you tell me earlier? I like you too, and I haven't dared to confess my love to you. .”

"what……"

Tong Xin was surprised and delighted by Lu Xin's words.

She has always liked Lu Xin, but since Lu Xin is her cousin-in-law, she can only keep this feeling in her heart.

Originally, she thought that as time passed, this relationship would gradually turn into family affection, but as she got along day and night, she found that she liked Lu Xin more and more, to the point where she couldn't sleep at night.

Today, she took this opportunity to pluck up the courage to confess to Lu Xin, and she was willing to go all out, and she was mentally prepared. If Lu Xin didn't accept it, then she would choose to leave Shenghai and go to Hong Kong Island.

As for her cousin Wei Jin, she can't control that much anymore, at worst, she will serve her husband like Queen E and Nv Ying.As long as Wei Jin is willing.

She had prepared for the worst, but unexpectedly, she waited for the best.

Two people go in both directions!
Just as she was about to say something, she saw her cousin Wei Jin stepping off the stage from the corner of her eye. She quickly got up and ran towards the entrance of the studio, almost bumping into the staff.

Lu Xin couldn't help laughing to himself.

Wei Jin who came over happily asked, "Hey, why did Miss Xinxin go?"

Lu Xin touched her head with a smile: "She's going to pee."

"Oh~" Wei Jin then happily asked: "Brother Lu Xin, do I sing well?"

Lu Xin nodded and praised, "You sing very well. Have you practiced singing?"

Wei Jin didn't understand modesty at all, nodded and said, "That's right! I can also play the piano and the violin."

"Wow, so powerful..."

Lu Xin was really surprised.

He always thought that Wei Jin had a simple mind, so she developed motor skills, but he didn't expect that she had musical skills.

Lu Xin praised again: "My wife, you are really amazing!"

Wei Jin moved his head closer, then raised his head and pouted, saying, "I want to kiss."

"it is good!"

Lu Xin rewarded her with a kiss.

"No, I want more!"

Lu Xin then kissed her again.

Wei Jin was as happy as a three-year-old child, giggling.

After listening to the song, I went to drink tea, only to see my cousin Sven picking up girls.

Relying on his pretty face and sharp tongue, Cousin Sven made the beauty laugh out loud.

Seeing Lu Xin and the others approaching, Cousin Sven stood up very gentlemanly, took out a business card from his pocket and handed it to the beautiful woman opposite, smiled and said a few words, then turned and left gracefully.

And the beauty glanced at the business card, and then followed the back of cousin Sven.

It seems that the beauty has fallen.

……

……

The assembly time of the lithography machine was slower than Lu Xin imagined.

Originally thought it was a month at most, but it actually took 15 days to install it all.

No way, the lithography machine is just one of the components. In fact, the entire chip manufacturing equipment is very, very large.
Of course, it also includes explaining various technical principles.

At 3:30 am on March 8, the lithography machine was officially assembled.

Witnessed by hundreds of lithography machine scientists, engineers and related leaders in dust-free suits, Zhang Xuebo, head of the lithography machine expert group of Huaxia Academy of Sciences, pressed the power switch with his own hands.

All the electronic indicators of the equipment are all on, and the self-test program is entered in the next second.

Everyone nervously looked at the data on the big screen.

Rows of green √ symbols were quickly swiped across the computer.

The 1-minute self-test passed successfully!

This means that this 5nm lithography machine is ready for trial production.

"Clap clap clap..."

There was thunderous applause at the scene, and it lasted for a long time. Everyone's face was full of excitement.

Many people had already burst into tears but didn't know it, and applauded vigorously.

They have been waiting for this day for too long!
However, at this time, it is still a small step away from Huaxia Chip's real breakthrough of the blockade.

One last small step.

Chips have another name called "integrated circuits".

To use an analogy, the huge circuit network of all the transmission lines and residential power lines of the State Grid in China is concentrated in the third ring of Kyoto, which can be called an integrated circuit.

And before producing chips, what is the first thing you need to do?That's right, it is to design an integrated circuit diagram.

This is also a very, very complex high-tech. After the design is completed, it needs to be verified. If there are bugs in the circuit diagram, it needs to be modified. When all the verification and testing are completed, the mass production test can be performed.

The purpose of the mass production test is to screen the quality of the chip, if the yield rate is not up to the standard, it cannot be produced.

While mass production testing is good or bad, it is necessary to increase the time for mass production testing, because the machines for testing are leased, which is similar to digging out national defense optical cables, and you have to collect money by the second, so the cost of testing is also very, very high. .

The foundry TSMC does not help you do these tasks, you need to do it yourself. Their lithography machines are only responsible for producing according to the circuit diagram you designed.

Huawei HiSilicon is doing this job, which is very technically difficult and requires a lot of manpower, material and financial resources.

The key is not necessarily success, otherwise it would not be HiSilicon's turn, and foreign companies have already succeeded.

Without a lithography machine, it is like a clever woman without rice. No matter how awesome the chips you design, what can you do even if you beat Qualcomm, Broadcom, and Nvidia? Without a lithography machine to produce for you, everything is equal to 0 .

Now they finally have a lithography machine.

As long as a 5nm chip is successfully produced, they can directly turn the table: Europe and the United States, I went to Nimal Gobi!
