Tianyu Xinghai, Ma Tian's office.

I saw Ma Tian sitting in his place, waiting for Xia Wei and the others to arrive, and Nie Zhenyuan made an appointment to meet him today.

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

Last night, when he wanted to follow a man's instinct to 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 now, so he directly kicked Ma Tian out of the room.

Then, Li Runqi, who closed the door, lay on the bed again, covering his face and snickering, his face flushed.

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

confirmed the relationship in a daze, but after confirming the relationship, he became shy, and Ma Tian also felt wonderful.

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

"Let him in!"

In a moment, Ma Tian saw Nie Zhenyuan, whose eyes were red and swollen but who was in good spirits.

Last night, Ma Tian had a pleasant barbecue party, but Nie Zhenyuan, who caught the plane to Xiang City, was tormented every second, and he couldn't wait to see Ma Tian at dawn as soon as possible.

For Xia Wei, the chip thing is like a fish in the throat, so that they can't eat well and sleep well.

"Mr. Ma, I am honored and happy to see you again!" Nie Zhenyuan came in and greeted him warmly, as if he was looking at a savior.

"Sit down, Mr. Nie!" Ma Tian glanced at Nie Zhenyuan, and there was a smile on the corner of his mouth, he could see that Nie Zhenyuan's state was not good, it seemed that Xia Wei was really tormented during this time.

"Let's talk about your Xia Wei, you don't have to keep it secret in front of me." Ma Tianzhengse said.

Tianyu Xinghai has long been a famous brand in China, and it is almost a prefix with the word "Zhong", so there is no need for Xia Wei to hide it from him.

Nie Zhenyuan naturally knew this, and said unreservedly that Xia Wei's contract for the purchase of chips was broken, and most of the high-precision chips in the mobile phone were refused to be manufactured by companies such as TSMC.

Ma Tian listened carefully and did not interject a word.

It wasn't until Nie Zhenyuan finished speaking that Ma Tiancai asked a question: "By the way, they have so many companies united, don't you notice it at all?" ”

Ma Tian doesn't believe that they are a piece of iron, such a big team and a team from different countries will always have flaws, it stands to reason that Xia Wei should not be so passive.

"Xia Wei was acted, and they were well disguised." Nie Zhenyuan sighed and talked about their internal summary.

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

To sum up, it is Xia Wei that some people are blinded by the strength on the surface, and the "wind and rain" of several years have made some people raise their heads and look down on their opponents.

In the past two years, I thought that I was the master if I had money, and I strongly guided the right to speak in front of the suppliers, thinking that the suppliers would not betray them, after all, who would not get along with the money.

When those supplier companies join forces to break out of goods and refuse to cooperate, they will be stupid, and the arrogance of the past will be returned by others, and even stabbed.

Ma Tian shook his head, and he was also a little glad that he played a good chess hand (at the end of chapter 104) back then, not only did he not enter high-precision electronic products, but instead let Xia Wei attract firepower in front and secretly jungle himself.

Thinking of this, Ma Tian also saw that Nie Zhenyuan was becoming more and more pleasing to the eye, Xia Wei is really a good company.

"Mr. Ma, that's roughly the case. At present, our inventory plus return to the factory may be enough to support our shipments for half a year, and we must find a replacement within half a year, otherwise we can only reduce production until finally we come up with our own chips in the summer. ”

Nie Zhenyuan didn't think that Xia Wei would collapse this time, he always firmly believed that even if there were no foreign high-precision chips, Xia Wei would be able to find a replacement for himself if he gave Xia Wei 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 domineering.

"There's no need to find other alternatives, Tianyu Xinghai will help you this time! You come with me! After speaking, Ma Tian got up and walked outside, followed by Nie Zhenyuan.

The two of them came to a secret elevator that went straight underground, and then walked inside.

This elevator goes straight to the bottom of the Tianyu Star Sea, and then the two of them take a small subway.

Nie Zhenyuan was stunned for a moment, the building under Tianyu Xinghai Company is really mysterious, and it feels like a special base in the movie.

After getting off the small subway, the two got on an elevator again, which can also be seen how secret Ma Tian is from the lithography machine department!

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

The two of them entered the dust room, and then put on dust jackets before entering the room, where many scientific researchers in white clothes were busy.

Seeing Ma Tian, a man in blue came to Ma Tian and greeted: "Mr. Ma!" ”

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

Ma Tian nodded and said, "Let's take our guests to see our latest fruits." ”

"Please!" Wang Xinghua gestured to Nie Zhenyuan with his hand, and then took the lead to walk 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 our company's latest research and development product TN-0902, which can already process 9nm chips." ”

After speaking, he said to a white cloth next to the console: "Xiao Lu, take a protosilicon lithography and show it." ”

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

After a while, the machine sounded a slight starting sound.

Wang Xinghua nodded, and said to Ma Tian and Nie Zhenyuan: "You may have to wait a few minutes to see the finished product we just experimented with." ”

Ma Tian also said to Nie Zhenyuan: "The highest precision requirement for your main chip is 7nm, at present, Tianyu Xinghai has been able to achieve 9nm, and I will work hard to break through to 7nm in the next six months, as for what chip you want, you have to design it yourself!" ”

Xia Wei was sure that he knew what chips he needed for his own system, and Ma Tian didn't think about acting on his behalf.

“9nm？” Nie Zhenyuan's heart became excited, he knew that Ma Tian still had something, although it was not the 7nm in the surprise, but 9nm was only the last order of magnitude away from 7nm.

And there is still half a year to make a breakthrough, let Ma Tian, the great god, make a breakthrough!

"Thank you so much, Mr. Ma, I 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 indescribable.

There is both the excitement of solving Xia Wei's current predicament, and the dreamy feeling of feeling too relaxed, the two feelings are superimposed, which can only make him hold Ma Tian's hand and shake there all the time.

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

The role of the lithography machine is mainly to expose the silicon wafer, in simple terms, here can be summarized in three main sentences What happens in the lithography machine:

1. Photomask: The lens set and the silicon wafer table will be precisely aligned and leveled.

2. Light source shines: You can think of it as a laser flashlight that emits several lightes.

3. Move the workpiece table: let the silicon wafer be exposed in an orderly manner.

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

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

For example, lenses. The ZEISS lens, with a surface undulation of no more than 0.05nm, is the proud work that can be said to be the closest to a three-body water drop in the earth's civilization, and the flatness has reached the atomic level.

The difficulty coefficient is extremely high, and design, materials, processes, and assembly are all indispensable.

Produced by ZEISS Mooni, ZEISS is the exclusive supplier of optical components for ASMAIL, which accounts for about 26% of ASMAIL's product costs.

"Exclusive" means irreplaceable, and "26%" means extremely costly.

It can also be seen from here that this lens is hanging more.

Of course, this technology was broken by Ma Tian and others, because he didn't want to pay Zeiss company.

Another example is alignment. The dual-workpiece table system, which needs to be synchronized and exposed, is one of the magic weapons of Acemael to defeat the lithography machine manufacturers in the island country, and now it is also one of the magic weapons for Tianyu Xinghai to defeat the lithography machine manufacturers in the island country.

Another example is the most important light source, the sympathetic light waves emitted when extreme ultraviolet light, driven by a 60-kilowatt laser, blasts liquid tin into plasma.

It is a special light source (Chapter 122) developed by Ma Tian according to the paper "A New High-precision Laser Processing Exploration" awarded to him by the system at 10 million impact value, and it will take at least 5 years for normal enterprises to develop this technology.

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

All in all, it is not unreasonable for the lithography machine to be called the pinnacle of human machinery, and the price can reach 1 billion, which is definitely worth the money.

After a few minutes, the processed wafers come out of the lithography machine and enter the next process, baking, or post-baking.

The purpose of this step is to compensate for the lack of exposure intensity by heating the photochemical reaction in the photoresist to fully complete it.

At the same time, it can also reduce the circle of lines caused by the standing wave effect after the lithography machine develops.

After drying, the previously exposed part is dissolved and removed, and the pattern on the photomask appears on the photoresist, which is then rinsed with deionized water.

Finally, the roast is carried out again, but this time it is called "solid film baking", of course, this is for the wet process, if it is a dry etching with plasma, this step can be omitted.

After so many steps, it came to the observation accuracy and measurement, which is the most intuitive achievement of Ma Tian to show this time - the lithography accuracy display.

The 9nm process is definitely not enough to see with an ordinary optical microscope, and everyone also came to the atomic force microscope table.

The staff in white put the silicon wafer that had just been processed several steps on the microscope table, and everyone could check the accuracy on it through the instrument.

The measurement results of 9nm are impressively displayed on the big screen.

Nie Zhenyuan didn't think that Ma Tian would lie to him for a long time, that is to say, Tianyu Xinghai really has the technology of lithography 9nm precision chips.

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