Technology company, I will become the light of China!

Chapter 83 Time is tight, stock up on parts in advance . After a night’s rest, Lin Tian couldn’t wait to go to Loongson International personally to produce the photomasks early the next morning.

Chen Xing and Qu Cheng were not in a hurry to leave the Magic City, but went to observe together.

They all wanted to see if Lin Tian was that all-powerful.

In the Loongson International Laboratory, a large number of lithography engineers came to watch with a learning attitude.

Facing the crowd of dozens of photolithography engineers watching and studying, Lin Tian didn’t have any stage fright, his eyes were calm and focused, completely different from his careless look the day before, and he started the preliminary production of the photomask in a familiar manner.

The production process of photomask is the same as that of chip production. It also needs to go through ten main steps: pattern production and conversion, exposure, development, etching, demoulding, cleaning, defect inspection, defect repair, shipping cleaning, and film sticking. It is different from chip production.

Chip production, photolithography machine exposure, and photomask cannot rely on photolithography machine exposure, but needs to use laser/electron beam direct writing method to expose Blankmask (photomask material).

When the positive photoresist is exposed, the chemical structure changes and photoacid is produced. Through the action of the developer, the exposed part of the photoresist is dissolved, while the structure of the exposed part of the negative photoresist is cross-linked, resulting in a non-soluble and stable form. The chemical structure is then retained through the action of the developer, and the exposed part is retained.

As the saying goes!

Experts will know if there is one as soon as they take action!

Lin Tian’s previous steps were completely correct, without any trace of an amateur, and the process was smooth and smooth without any delay. He was like a veteran who has experienced tens of thousands of photomask productions, and everything fell into place.

This also impressed Gao Yongming, Tang Xinyu, and all the onlookers’ lithography engineers from the bottom of their hearts. They understand lithography machines and masks. They are simply all-around geniuses!

While waiting for the etching gap for the first tape-out, Tang Xinyu, deputy chief engineer of Loongson International, rubbed his hands and couldn’t help but ask for advice:”Excuse me, Lin Gong, do you have any good way to solve the standing wave effect?

” Wave effect, during the photolithography process, a part of the light will be reflected back. This reflected light has the same frequency as the original incident light and will interfere with each other, resulting in uneven distribution of light intensity in the photoresist layer, showing alternating bright colors. Dark areas lead to tape-out failure.

How to effectively reduce the standing wave effect has always been a headache for them.

Lin Tian moved his eyes away from the equipment and said calmly:”Use TARC, BARC and other anti-reflective layer materials, or heat and bake, and use high temperature to promote the diffusion of the photosensitizer, which can make up for the uneven light intensity distribution to a certain extent. problem, a more uniform pattern profile can be obtained during the development process”

The sound was not loud, but it spread throughout the laboratory.

Loongson International’s engineers did not hesitate and immediately took out their notepads to record.

Although this”forest engineer” is young, his achievements and attainments in the field of lithography have already far surpassed everyone present.

However. at this time.

Feng Chengming, who caught the latest flight and flew back overnight, said,”If chromium oxide is used as the anti-reflective layer, can most of the standing wave effect be eliminated?”

“Um”

Lin Tian nodded and blurted out:”Using chromium oxide as an anti-reflective layer with a thickness of 20 nanometers can effectively solve the standing wave effect.”

Feng Chengming:”Why 20 nanometers?”

“The thickness of 20 nanometers can already solve most of the standing wave effects. 21 nanometers is not useful and 19 nanometers is not enough.”

Lin Tian replied calmly.

The questions and answers between the two people made Chen Xing, who was watching silently, marvel, red quality talents are indeed a bit perverted!

Chat with the Confucian scholars and answer all questions

“The old man who just spoke is the chief lithography chief of Loongson International.” Qu Cheng lowered his voice a bit and introduced.

“It turned out to be him”

Chen Xing couldn’t help but smile, this old man was so legendary.

He boasted so much that he fooled a group of academicians. If it can be proven that multiple exposure technology can be used to realize a 14-nanometer chip, then his bragging will be considered realized.

“It takes a long time to make photomasks. A single tape-out takes 1 to 3 days. I suggest Mr. Chen not to wait any longer. The company cannot live without you.”

Qu Cheng reminded him.

It takes 1 to 3 days at a time. According to Lin Tian’s calculation, the 14nm chip mask will need to go through about 50 tape-outs in total before it can be finally packaged and used.

It will take 50 days at the earliest. This time is really tight.

Since Double Eleven is too late, Chen Xing can only rely on seeing samples of the 14nm Qingzhou processor chip on Double Eleven.

Even if there is only one, he can assemble a prototype phone to facilitate his subsequent launch of a new flagship mobile phone.

After witnessing Lin Tian’s strength and realizing once again the abnormality of red-quality talents, Chen Xing also followed Qu Cheng’s suggestion:

“Well, since the tape-out time is so long, I’m going back to Shencheng tonight. Do you want to come with Mr. Qu?”

“No more”

Qu Cheng shook his head, glanced at Gao Yongming not far away and said,”Chief Gao and Bai Yan are responsible for the chip design, as well as those old guys. I’ll watch it for you here to prevent Gao Yongming from digging into it.” Sitting in a corner”

Gao Yongming:”……”

The volume of this sentence increased a lot, and it fell clearly into Gao Yongming’s ears.

Poaching?

Is he such a person?

Although…it’s true…well…there are hundreds of millions of points that he wants to dig up, but Qu Cheng’s words are too straightforward, right? He doesn’t want to lose face, right?

The corners of Gao Yongming’s eyes twitched twice, and he coughed twice and reassured:”Don’t worry, Mr. Chen, I’m not that kind of person.””

“Do not believe”

Qu Cheng glanced at him lightly.

The super level shown by Lin Tian even made him tempted. He wanted to poach the Dragon Academy. Can you, Gao Yongming, resist the temptation?

Pack!

You kid is pretty good at pretending!

Gao Yongming blushed and did not continue to quibble, but complained:”Mr. Qu, please stop sowing discord. Mr. Chen and I hit it off instantly. If I didn’t want to take advantage of him, I would have sworn sworn friends with him in Taoyuan.”

“Oh, anyway, don’t have any evil thoughts”

Qu Cheng smiled and said

loadAdv(7,3);

“I believe that Mr. Gao is not someone who likes poaching, and Loongson International has so many talents that there is no need to do so.”Chen Xing finished his words, leaving Gao Yongming with no room for maneuver.

However, he was not worried, because there was loyalty, and there was no need to worry about the talents rebelling.

As long as Chen Xing did not squeeze and let the system talents work 24 hours a day, Then the loyalty will not be reduced, and he has always been in a state of freeing up these talents.

Listening to Chen Xing’s impeccable praise, Gao Yongming did not dare to poach people. Even at this age, he still cares about his face. Yes, it will have a bad impact if word spreads.

After a few simple polite words, Chen Xing also said goodbye:”Mr. Naqu, Mr. Gao, I will go back to Shencheng Company first. If there is any progress, you can send me a message on WeChat.””

“Well, don’t worry, I’m watching over here. Qu Cheng nodded and said.

Gao Yongming was speechless and at the same time showed a hint of surprise and said,”Why don’t you stay for two more days?” We brothers haven’t had a good drink yet.”

“No, I understand Mr. Gao’s wishes. There are still things to deal with in the company.”Chen Xing responded with a smile.

“Okay, then you pay attention to safety, I will ask someone to speed up the chip progress”

“Thank you, Mr. Gao”

“Don’t be so polite, we are all allies!”

��After a few polite words, Chen Xing left the Loongson International headquarters and returned to the hotel to pack his luggage.

It was already mid-October, and there were only two and a half months until the end of December, so he had to hurry up.

Due to Apple’s”declaration of war” this time, in order to prevent the United States from causing trouble, suppliers suddenly cut off supply. Chen Xing also learned a lesson this time and stocked up on major spare parts in advance.

He wanted to stock up as much as possible on Carl Zeiss lenses, memory chips, and M series assemblies.

We also need to discuss alternatives for other parts and purchase as many as possible.

……

Peninsula Seoul.

Korean Star Group Headquarters Building.

Li Zhenzhen listened to the report of his subordinates, his eyes showed a hint of surprise, and then he murmured with a faint smile on his lips:

“I thought he was joking, but I didn’t expect that Chen Xing, you really want to enter the high-end market and compete head-on with Apple phones.”

“interesting”

She looked at the secretary and ordered:”Instruct the factory to replace all the screen assemblies supplied to Longxing Technology with our latest M7 screens.”

“good president”

The secretary immediately went to do it.

She didn’t ask why, because the secretary didn’t need to know much.

After the office door was closed, Li Zhenzhen joked lightly:”It’s really courageous. If you, Chen Xing, really do it, I don’t know what the expression of that old guy in Pou Ke will be. Will he get himself into trouble?”

What if ? self-disruption……

The curve at the corner of her mouth became more obvious.

You know, in the world’s high-end mobile phone market, only Apple can compete with Korean Star Group.

If Apple gets into trouble and launches strategies such as discounts and price reductions in Dragon Kingdom, then Korean Star Group will have room to maneuver. It can bribe World Newspapers and promote differential treatment, and maybe it can further erode its position in the United States and the West. market.

As for Wall Street?

As long as those people make money, they don’t care whether Apple is a local company.

Business competition and the law of the jungle are their wolf culture.

Of course.

The premise is that the BOSS does not end.

Because of fear, Li Zhenzhen didn’t dare to be too public, lest he would bring trouble to the big boss, but it was still possible to secretly supply an M7 screen.

……

As the direct flight from Magic City to Shenzhen City landed, Chen Xing also returned to a familiar place and asked the driver to go straight to Longxing Technology Company.

After returning to the president’s office, he didn’t pause for a moment and immediately checked his mailbox to track the progress of parts supply.

Fortunately, everything is on track!

Fifty thousand sets of Carl Zeiss lenses, with a total value of 60 million, have been loaded and shipped by sea, and are expected to arrive within a month.

Micron and Hynix collected 50,000 memory chips each of 32G, 64G, and 128G, which is equivalent to 100,000 pieces each, totaling 67 million.

There are also various small parts and chips that are already on the way.

Generally speaking, for large-scale international trade orders, the deposit paid is 60% of the purchase price. Chen Xing can still afford this amount and does not need to go to the bank to apply for a loan.

“dong dong——”

After Yao Nana learned that Chen Xing had returned from a business trip, she eagerly knocked on the door of the president’s office with her market research questionnaires for the past few days.

Although the statistical results of the online survey questionnaire have not yet been released, the offline random survey questionnaire has already produced results that can be referenced.

The people interviewed include not only students, teachers, business white-collar workers, but also evaluation bloggers.

This offline research report is still of great reference value.
