My technology affects the whole world

Tianyu Xinghai, Ma Tian's office.

I saw Ma Tian sitting blankly in his seat, waiting for the arrival of Xia Wei and others. Nie Zhenyuan made an appointment with him today.

However, Ma Tian's mind kept thinking about what happened last night.

Last night, when he wanted to follow the man's instinct and take the next step, he was rejected by the shy Li Runqi, saying that he didn't want Ma Tian to see her ugly appearance, so he kicked Ma Tian out of the room.

Then, Li Runqi, who closed the door, lay on the bed again, covering her face and laughing, her face turning red.

Mr. Lao She once said that a girl's blush is better than a long confession. That touch of plateau red is the most memorable appearance of a girl in the hearts of men. Unfortunately, Ma Tian did not see it.

He vaguely confirmed the relationship, but after confirming the relationship, he became shy. Ma Tian also felt strange.

"Mr. Ma, Mr. Nie is already waiting in the lobby." The secretary's voice came, interrupting Ma Tian's thinking.

"Invite him in!"

In a moment, Ma Tian saw Nie Zhenyuan, whose eyes were red and swollen but who was working hard.

Last night, Ma Tian had a pleasant barbecue party, but Nie Zhenyuan, who had to catch a plane to Hunan City, was suffering every second and wished he could see Ma Tian earlier at dawn.

For Xia Wei, the chip issue was like a lump in their throats, making them unable to eat or sleep well.

"Mr. Ma, I'm honored and happy to see you again!" Nie Zhenyuan came in and greeted him warmly, as if he were looking at the savior.

"Sit down, Mr. Nie!" Ma Tian looked at Nie Zhenyuan with a smile on his face. He could see that Nie Zhenyuan was not in good condition. It seemed that Xia Wei was really suffering during this period.

"Tell me about Xia Wei, you don't have to keep it secret in front of me." Ma Tian said seriously.

Tianyu Xinghai has long been a famous brand in China, it just needs the prefix "中", so Xia Wei has no need to hide it from him.

Nie Zhenyuan naturally knew this, and told him without reservation that Xia Wei's chip purchase contract was broken, and most of the high-precision chips in mobile phones were refused to be manufactured by companies such as Moss Semiconductor Manufacturing Co., Ltd.

Ma Tian listened carefully without saying a word.

It wasn't until Nie Zhenyuan finished speaking that Ma Tiancai asked a question: "By the way, so many of their companies have joined together, haven't you noticed at all?"

Ma Tian didn't believe that they were a piece of metal. Such a big team from different countries would always have flaws. Logically speaking, Xia Wei shouldn't be so passive.

"Xia Wei was played, and they disguised it very well." Nie Zhenyuan sighed and talked about their internal summary.

They have also internally reflected on the issue of Ma Tian, ​​and many people were even held accountable, including Mr. Ren who was furious at the meeting.

To sum up, some people in Xia Wei were blinded by the apparent strength. Several years of "good weather" have made some people look at others with their heads high and look down on their opponents.

For the past two years, I have thought that I am the boss if I have money, and have strongly guided the right to speak in front of suppliers, thinking that suppliers will not betray them, after all, no one can live with money.

When those suppliers and companies joined forces to sell out goods and refused to cooperate, people became stupid, and their former arrogance was repaid in full, and even stabbed in the face.

Ma Tian shook his head, and was a little glad that he had played a good game back then (at the end of Chapter 104). Instead of entering into high-precision electronic products, he let Xia Wei attract firepower from the front and secretly farmed and developed by himself.

Thinking of this, Ma Tian became more and more pleased with Nie Zhenyuan. Xia Wei was really a good company.

"Mr. Ma, the situation is roughly like this. Our current inventory plus returns to the factory may be enough to support our shipments for half a year. We must find substitutes within half a year, otherwise we can only reduce production until we finally come up with a solution for Xia Wei Come out with your own chip.”

In the end, Nie Zhenyuan did not think that Xia Wei would collapse this time. He always believed that even if there were no foreign high-precision chips, Xia Wei could come up with a replacement if he was given two years.

This is Xia Wei, a technology company with tens of thousands of patents, hundreds of billions of funds, and a large number of talents and scientific research capabilities.

Full of confidence and domineering.

However, Ma Tian is more confident and more domineering.

"There is no need to find another substitute. Tianyu Xinghai will help you this time! You come with me!" After saying that, Ma Tian got up and walked outside, followed by Nie Zhenyuan.

The two came to a secret elevator that led directly to the underground, and walked in.

This elevator leads directly to the underground of Tianyu Xinghai, and then the two of them take a small subway.

Nie Zhenyuan was stunned for a moment. The building under Tianyu Xinghai Company was really mysterious. It felt like a special base in the movie.

After getting off the subway, the two got into an elevator. From this, we can see how secretive Ma Tian is about the lithography machine department!

After getting out of the elevator and walking a short distance, a large room like a factory with a large number of large machine tools appeared in front of you.

The two entered the dust room, then put on dust coats before entering the room. There were many scientific researchers in white clothes busy inside.

Seeing Ma Tian, ​​a man in blue came to Ma Tian and said hello: "Mr. Ma!"

It was Wang Xinghua, the lithography machine research director previously appointed by Ma Tian.

Ma Tian nodded and said, "Let's show our guests our latest fruits."

"Please!" Wang Xinghua gestured to Nie Zhenyuan with his hand, then took the lead and walked forward.

After a while, the three of them came to a machine. Wang Xinghua looked at the machine in front of him and said, "This is the latest product developed by our company, TN-0902. It can already process 9nm chips."

After speaking, he said to a man in white clothes next to the console: "Xiao Lu, take a piece of raw silicon photolithography and show it."

"Okay!" Xiao Lu nodded, stood up, took out a raw silicon wafer from the experimental table, and put it into the machine.

After a while, the machine made a slight startup sound.

Wang Xinghua nodded and said to Ma Tian and Nie Zhenyuan: "It may take a few minutes to see the finished product we just experimented with."

Ma Tian also said to Nie Zhenyuan: "The highest accuracy requirement for your main chip is 7nm. Currently Tianyu Xinghai can achieve 9nm. In the next six months, I will work hard to break through it to 7nm. As for the chip you need, you have to design it yourself." Got it!"

Xia Wei was certain that he knew what chips were needed for his own system, so Ma Tian didn't think about overstepping his authority.

"9nm?" Nie Zhenyuan became excited. He knew that Ma Tian still had something. Although it was not the 7nm that was surprising, 9nm was only one order of magnitude away from 7nm.

And there is still half a year left, so if the great master Ma Tian takes action, it may not be impossible to achieve a breakthrough!

"Thank you so much, Mr. Ma. Let me first thank you on behalf of our Xia Wei!" Nie Zhenyuan shook hands with Ma Tian vigorously, with a smile on his face. His mood at this moment was simply indescribable.

There was both the excitement of solving Xia Wei's current predicament and the dreamy feeling of being too relaxed. The two feelings superimposed could only make him hold Ma Tian's hand shaking there.

Then Ma Tian calmly pulled it out and looked at the lithography machine in front of him.

The main function of a photolithography machine is to expose silicon wafers. To put it simply, what happens in the photolithography machine can be summarized in three sentences:

1. Photomask: The lens assembly and silicon wafer worktable will be precisely aligned and leveled.

2. The light source emits light: You can imagine it as several glowing laser flashlights.

3. Move the workpiece stage: allow the silicon wafer to be exposed in an orderly manner.

In three sentences, a photolithography machine cost more than 1 billion yuan, which naturally has its own reason.

Although these three sentences are unremarkable, they contain many pinnacles of human engineering, including the black technology developed by Ma Tian System.

Such as lenses. The Zeiss lens, whose surface undulations do not exceed 0.05nm, is the proudest work of earth civilization that can be said to be closest to the three-body water droplet, and its flatness reaches the atomic level.

The degree of difficulty is extremely high, and design, materials, craftsmanship, and assembly are all indispensable.

Produced by Zeiss in Munich, Zeiss is Asmer's exclusive supplier of optical components. Zeiss's optical components for photolithography machines account for approximately 26% of Asmer's product costs.

“Exclusive” means irreplaceable, and “26%” means extremely costly.

It can also be seen from here that this lens has a lot of weight.

Of course, this technology was broken by Ma Tian and others because he did not want to pay Zeiss.

Another example is alignment. Alignment requires a dual workpiece stage system that can synchronize and expose. It is one of the magic weapons for Esmail to defeat the island country's lithography machine manufacturers. It is also one of the magic weapons for Tianyu Xinghai to defeat the island country's lithography machine manufacturers.

Another example is the most important light source - extreme ultraviolet light driven by a 60-kilowatt laser that blasts liquid tin into plasma.

It is a special light source developed by Ma Tian based on the "Research on a New High-Precision Laser Processing" paper awarded to him by the system with an impact value of 10 million (Chapter 122). For this technology, it would take a normal company at least 5 years to research it. come out.

There are many more, so I won’t give examples here.

All in all, it is not unreasonable for the photolithography machine to be called the pinnacle of human machinery. The price can reach hundreds of billions, and it is definitely worth the money.

A few minutes later, the processed silicon wafer comes out of the photolithography machine and enters the next process - baking, also referred to as post-baking.

The purpose of this step is to fully complete the photochemical reaction in the photoresist through heating, which can make up for the problem of insufficient exposure intensity.

At the same time, it can also reduce the circles of lines caused by the standing wave effect after the photolithography machine is developed.

After post-baking, the previously exposed parts are dissolved and removed. The pattern on the photomask appears on the photoresist, and then rinsed with deionized water.

Finally, bake again, but this time it is called "hard film baking". Of course, this is for wet etching. If dry etching with plasma is used, this step can be omitted.

After going through so many steps, we came to the observation accuracy and measurement, which is the most intuitive result that Ma Tian wants to show this time - photolithography accuracy display.

The 9nm process is definitely not enough to be seen with an ordinary optical microscope, so everyone also came to the atomic force microscope stage.

The staff in white clothes placed the silicon wafer that had just undergone several steps of processing on the microscope stage, and everyone could carefully check the precision on it through the instrument.

The 9nm measurement results were displayed on the big screen.

Nie Zhenyuan didn't think that Ma Tian would lie to him for a long time. In other words, Tianyu Xinghai really had the technology to photolithography 9nm precision chips.

Now as long as Xia Wei has a chip design drawing of his own, Tianyu Xinghai can help them create a chip with at least 9nm precision.
