Technology company, I will become the light of China!

Chapter 85 Witness history, the 14nm Qingzhou processor comes out!
"Chief Lin, photomask No. [-] has been cleaned!"

"The No. [-] photomask has also been cleaned!"

"Report to Chief Lin, after repeated confirmation, no dust was found on the surface of the first set of photomasks, and trial production can begin!"

"Chief Lin, the parameters of the 20nm process lithography machine have been debugged, please give instructions!"

Dragon Kingdom Magic Capital.

Loongson International Experimental Base.

Lin Tian was wearing a white coat and sitting on a chair with his legs crossed. In front of him was a group of busy lithography engineers.

Next to him, Feng Chengming, an academician in the field of lithography, rubbed his hands excitedly, lowered his posture and said: "Chief Lin, the photomask and lithography machine are ready. Do you think we should try mass production?" Got the chip?"

His tone was gentle, not like the gentleness of an elder to a junior, but the tone of a student meeting his teacher with respect.

No one knows what Feng Chengming and the Loongson International engineers have been through during this period, to think that they would behave like this to a young man in his early twenties.

Lin Tian took out his mobile phone and looked at the date, muttering to himself: "December 12th, no more, no less, it took exactly 6 days. The Dutch engineer didn't come today, did he?"

"Mr. Qu and the others have already sent him away."

Feng Chengming answered quickly.

Dutch engineer, given as a gift when buying a 20nm process lithography machine.

Don’t think that the Dutch ASML company is kind-hearted. It sells photolithography machines and comes with a few engineers. In fact, these people are here to supervise the operation of the machines.

Their job content is that they don't have to do anything, but Loongson International has to pay them wages, and they also have the authority to lock the equipment.

To be blunt.

You’ve spent money, but you can’t use it casually, and you can stop whenever they want.

This management model is not limited to the field of photolithography machines. The original manufacturers of high-precision machine tools, heavy machinery, automobile production equipment, etc. will all be equipped with a few engineers who work for free.

They supervise the use of the equipment. Some networked equipment also has the function of automatically locking if it is moved even a little bit. If it is locked, you need to seek help from an "original factory engineer" to unlock the equipment.

Want not to be monitored?
Either buy an outdated version of the device or not buy it at all.

But if Longguo wants to develop, and if Longguo's local companies want to develop, they have to buy it, and they can only accept such an aggrieved management model.

Because these Dutch engineers don't understand lithography, they have no idea what the fifty-day Loongson International engineering team is doing, and they don't want to understand.

The Dutch company ASML assigned them two tasks: to monitor the operation of Loongson International's 20-nanometer process lithography machine and to report on the production tasks of the lithography machine.

This means that no matter what type of chips or new technologies Loongson International produces, they cannot escape Western surveillance.

but!It is worth mentioning that the production of 14-nanometer chips does not necessarily require the use of 20-nanometer process lithography machines. 28-nanometer process lithography machines can still be produced.

The use of a 20nm process lithography machine this time was purely because Lin Tian wanted to quickly produce the first batch of 14nm Qingzhou processors and send them to Chen Xing to facilitate the subsequent new flagship launch conference.

现在已经12月6号了，距离12月12号仅剩6天时间，他必须抓紧时间生产，赶在9号前把轻舟处理器芯片送过去。

When he heard that the Dutch engineer had left today, Lin Tian stood up and glanced at the engineers of Loongson International and said:
"Pay attention, I only teach once. How much you can learn and how much you can master depends on your own talent."

In terms of talent, all the engineers here are geniuses and are the top picks from various provinces in the Dragon Kingdom.

"Okay Chief Lin!"

"Chief Lin, I have a bad memory. Can I record it?"

"If we can master the key points of multiple exposure technology, it will be equivalent to breaking through the theoretical 7-nanometer chip process!"

"Let's get started, Chief Lin!"

Engineers echoed.

In fifty days, he went from an unknown young man to the honorary chief of lithography of Loongson International. Although there was no official announcement, this was already a tacit fact.

Lin Tian, ​​who impressed so many geniuses and even academicians, only did one thing, and that was that during the tape-out, he not only performed smoothly, but also had solid theoretical knowledge, and could answer the problems encountered in all aspects. The film plate was also successfully completed under his leadership, and there were no mistakes in the whole process.

Feng Chengming took a step forward, looked at the Loongson International engineers and said, "Look carefully, Chief Lin can't always teach us here. Do you understand?"

"I understand, Chief Feng."

"I understand."

"I know Chief Feng."

Engineers from Loongson International responded one after another. Now they all want to install cameras in their eyes.

"Let's go, we're in a hurry." Lin Tian walked to the locker room.

When entering the lithography machine area, you must wear dust-proof clothing. Any trace of dust may affect final production.

Dozens of engineers from Loongson International followed closely behind.

……

the other side.

Meeting room at Loongson International Headquarters.

Qu Cheng, who had two big bags under his eyes and gray temples, poured tea and said with a smile: "Mr. Rabbits, try the authentic Lao Ban Zhang brought by my trustee."

At his side, Gao Yongming assisted and said: "Mr. Qu is so grand. I have collected this old class seal for ten years, right?"

Qu Cheng glanced at him and said lightly: "Exactly ten years."

Sitting across from him, the blond, blue-eyed and skinny Rabiz was startled and thanked him in broken Chinese: "Although I don't understand tea, but I have been collecting it for ten years, so this must be a good thing."

"That's natural."

Qu Cheng had no expression on his face and replied calmly.

After hearing this, Rabbits also picked up the tea cup and tasted it carefully: "Hmm... the aroma of tea is so strong, and there is a sweet taste after drinking it. This is what you people in the Dragon Kingdom call Hui Gan, right?"

"That's right, this is the kind of return that only authentic Lao Banzhang can have."

Qu Cheng chatted.

Gao Yongming, who was sitting on one side, wriggled his lips slightly, biting his inner lip with his teeth, using pain to reduce his smile.

Ten years old class chapter?
How can I really give you a drink?
For this freeloader, the "living surveillance camera" responsible for monitoring their use of lithography machines will be fine if they don't give you poison, and they will give you a ten-year-old class seal.

But what Gao Yongming didn't expect was that despite his age, Qu Cheng could be so damaged and still perform so well.

The industrial tea I bought for 20 yuan was said to be authentic Lao Ban Zhang.

"what!"

After drinking the second cup, Rabitz also got straight to the point: "You two are looking for me for more than just tea, right?"

"Yes, I'm looking for you to order a photolithography machine." Qu Cheng said calmly.

When Gao Yongming got to the point, he also stated his purpose: "We want to order another lithography machine with a 20-nanometer process."

"Oh? You want to expand production?"

Rabbits looked at Gao Yongming and asked.

Gao Yongming nodded, thinking about how to delay time and said: "I want to try to take orders for 20 nanometers. Oh, by the way, do you think the 14 nanometer EUV lithography machine can..."

Before he finished speaking, Rabitz interrupted: "Sorry, Mr. Gao, I can't have the final say on EUV lithography machines. You yourselves know very well who is restricting you."

"That's right. Let's continue talking about the 20-nanometer process DUV lithography machine." Qu Cheng smoothed things over.

The two men's task is simple, which is to delay for enough time.

It's probably almost done when another Dutch engineer comes to take over the shift, so just delay it as hard as you can now.

……

Chip production workshop.

Inside the 20nm process lithography machine.

The first photomask has been installed, and the lens of the lithography machine is emitting a deep ultraviolet light source with a wavelength of 193 nanometers. Each exposure will engrave the designed chip circuit pattern on the bottom wafer.

With the continuous movement of the mobile platform and the continuous exposure of the photolithography machine lens, the wafer is engraved with dense chip circuit diagrams. If it is to produce a 20-nanometer chip, the photolithography has been completed by now and can be sent directly to cutting and packaging inspection. .

However, when using a DUV lithography machine to produce 14-nanometer chips, one exposure simply cannot meet the demand and requires a second exposure.

"Take out the first photomask and install the second photomask." Lin Tian looked at Feng Chengming and said.

Feng Chengming immediately followed suit.

When the second photomask was placed into the lens of the lithography machine, Lin Tian began to calibrate it himself and explained: "Listen up, the difficult part of multiple exposure technology is the alignment of the wafer. If there is a deviation between the two points, , the second exposure will damage the circuit pattern left by the first exposure, so be careful.”

After confirming that there was no problem, he looked at Feng Chengming and said: "Apply the photoresist twice and perform the second exposure step."

"understood."

Feng Chengming heard what he was told and did as he was told. "The photoresist must be evenly distributed. This shouldn't be a problem for you." Lin Tian said calmly.

After the secondary step is ready, the lithography machine is started again and begins secondary exposure on the bottom wafer.

The steps may seem simple, but in fact any small error may cause the entire wafer to be scrapped.

If a wafer is scrapped, it is a loss of 10,000+.

Because a 12-inch wafer, also known as a silicon wafer, can cut out about 500 chips.

Based on the market price of the Snapdragon 810 processor of 300 yuan, damaging a wafer is equivalent to a loss of 15 yuan.

Of course.

The 14nm Qingzhou processor will be more expensive!
As the lithography machine starts, deep ultraviolet light with a wavelength of 193 nanometers is continuously exposed, and the mobile platform at the bottom also moves continuously to make up for the shortcomings of the first exposure of the circuit pattern.

Minutes passed.

The second exposure of the wafer is completed.

After waiting for a while, Lin Tian put on gloves and took out the wafer himself. He squinted his eyes and carefully observed the circuit pattern. There was no overlap in the pattern, but he still needed to test it.

"Expedited delivery for cutting test."

Feng Chengming looked at the engineer beside him, winked and said, "Xiaolong, take it to the cutting test."

"I?"

The engineer was stunned.

He hasn't practiced it yet. What if he can't learn multiple exposures?

Feng Chengming glared at him, as if to say, if you don't want to go, do you want me to go?

no way.

The engineer had no choice but to do so.

"Okay, I've given you a demonstration. Try it yourself. The difficulty is focused on wafer alignment."

Lin Tian took a step back and said.

As the chief executive of Loongson International, Feng Chengming naturally did his part and said, "Then let me give it a try."

However, the seemingly simple steps caused the academician to fail several times. The difficulty of alignment was far more difficult than imagined. A slight deviation caused the loss of more than half of the chips.

"Be careful and take your time."

Lin Tian was not in a hurry, it was not his money that was wasted anyway.

While Feng Chengming was still groping, an engineer stepped forward and said, "Chief Lin, why is there no deviation in your alignment? Chief Feng just..."

"Ah!"

Lin Tian sneered, raised his head slightly and said, "My eyes are rulers. They are all experiences. Learn from them."

Another half hour passed.

The engineer who ran to cut the wafer was now walking quickly towards the photolithography machine production area.

When he came to Lin Tian, ​​he could no longer hold back his excitement and said: "Success, Chief Lin, we have succeeded! 14-nanometer processor chips can really be produced through multiple exposure technology!"

"My God! Is this true?"

"Are you sure it works?"

"I feel like I've witnessed history, does anyone want to pinch me?"

"Hahaha! Overtaking on a curve!"

The engineers were amazed, and even Feng Chengming couldn't help but be moved, and quickly asked: "Is the power consumption exceeding the standard? How much has the performance improved compared to 28 nanometers?"

"It does not exceed the standard. The maximum operating power consumption is 18W. The chip performance is unknown, but what is certain is that it is at least 50%!"

"Wow!!!"

There was an uproar at the scene.

The engineers couldn't stand it any longer and applauded in unison, and the warm applause resounded throughout the chip production workshop.

From this moment on!
Who dares to say that Longguo cannot make 14nm chips?

Are Western restrictions on lithography machines?
Can it be restricted?

However, Lin Tian remained as calm as ever, without any disturbance at all.

14nm chip…

It was too easy for him.

Even if it is a 3-nanometer chip, he can produce it as long as he has designed data files and EUV lithography equipment.

"Chief Lin, look at this chip..."

Before Feng Chengming finished speaking, Lin Tian responded calmly: "All packaging and testing, if there is no problem, send it to Longxing Technology as quickly as possible. Remember, the speed must be fast, without any delay."

"You go and package the chip."

Feng Chengming continued to arrange for engineers to do the work, while he continued to familiarize himself with wafer alignment and explore experience.

……

Dragon Kingdom Deep City.

SEG Technology Park.

After changing into a T-shirt, the sunny and handsome Chen Xing was checking the results.

Since establishing the sub-brand, he has become more certain about the segmentation of the mobile phone field and focused on optimizing heat dissipation issues.

Purple cooling talent Xu Xin took out a mobile phone case and introduced it emphatically: "President, this is the radiator mobile phone case I am talking about. It is specially made for game enthusiasts."

"Not only can it protect the phone, but the built-in heat conductor will also take away heat as the small fan rotates. The disadvantage is that it is a bit thick, but it should be fine if it is sold as an optional product."

"Not bad, worth trying."

Chen Xing nodded.

Xu Xin is a purple-quality cooling talent he recruited half a month ago. It must be said that he does have a lot of ideas.

In addition to introducing the mobile phone case radiator, he also designed a traditional clip-on radiator, which focuses on giving users a variety of choices.

Like to play games?
The radiator must be installed.

Before 2015, Chen Xing had arranged radiators for users, which was far ahead of its peers.

In addition to gaming performance mobile phones, high-end business mobile phones have also been designed and the production of appearance parts has been put into production.

Now everything is ready, all it needs is the processor chip to be in place.

If the 12nm Qingzhou processor has not completed mass production before December 10th, the only option is to use the Orion processor.

Of course.

If you arrive before December 12th, it’s still not too late.

Even if it is a new machine registration, Chen Xing has enough connections to speed up the review. After all, he now knows many academicians.

"Buzz-"

The pocket phone vibrated twice.

Chen Xing took it out and saw that the notification bar showed a message from Lin Tian, ​​which made his fingers tremble slightly.

Could it be…

Are you coming?

When he suppressed his excitement, he clicked on the WeChat chat box.

[Lin Tian]: "Oh."

Two simple words are worth a thousand words.

Light boat!

It's finally here!
Chen Xing suddenly felt a sense of relief that he could see the light through the clouds. He could not catch up with the Double Eleven Singles' Day, but he could give a small technological shock to the Longguo mobile phone market during the Double Twelve e-commerce shopping festival. !
　I’ll report my results. It’s already been booked and will be updated by 30 words in the next [-] days.

　　In addition, I would like to thank Fengqing Zone for the huge reward. If you spend the money, just subscribe to read the book. At the same time, thank you to all the readers who follow the book and give monthly recommendation tickets. Thank you.
