Chapter 85 Witness history, the 14nm Qingzhou processor comes out!
"Chief Lin, the cleaning of photomask No. 1 has been completed!"
"The cleaning of photomask No. 2 has also been completed!"
"Report to Chief Lin, After repeated confirmation, no dust was found on the surface of the first set of photomasks, and trial production can be carried out!"
"Chief Lin, the parameters of the 20-nanometer process lithography machine have been debugged, please give instructions!"
The Magic City of Dragon Kingdom.
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.
Beside 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. You see, we are Shouldn’t we try to mass-produce chips?”
His tone was gentle, not like the gentleness of an elder to a junior, but the tone of a student meeting his teacher.
No one knows what Feng Chengming and the Loongson International engineers have been through during this period, to think that they would treat a young man in his early twenties like this.
Lin Tian took out his mobile phone and looked at the date, muttering to himself: "December 6th, no more, no less, it took exactly 50 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 several 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.
Let’s be blunt.
You have 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 eat and drink 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 a backward version of the device, or not buy it at all.
If Longguo wants to develop, and the local enterprises in Longguo 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 ASML company 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.
It was already December 6th, and there were only 6 days left before December 12th. He had to hurry up and deliver the Qingzhou processor chip before the 9th.
When he heard that the Dutch engineer had left today, Lin Tian stood up and glanced around the engineers of Loongson International and said:
"Pay attention, I only teach once. How much you can learn and how much you can master is up to you." It’s my own talent.”
In terms of talent, all the engineers here are geniuses, and they are the top talents from various provinces in the Dragon Kingdom.
“Okay Chief Lin!”
“Chief Lin, I have a poor memory, can I record it?”
“If we can master the key points of multiple exposure technology, then It’s equivalent to breaking through the theoretical 7-nanometer chip technology!”
“Let’s start, Chief Lin!”
The engineers all agreed.
In fifty days, from an unknown young man to the honorary chief of lithography of Loongson International, although there is no official announcement, this is already a tacit fact.
Lin Tian only did one thing to impress so many geniuses and even academicians, and that was not only did he operate smoothly during the tape-out, but he also had solid theoretical knowledge and could answer all aspects of the problem. The photomask was 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 understand, Chief Feng.”
Loongson International’s engineers 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 photolithography machine area, you must wear dustproof clothing. Any trace of dust may affect the final production.
Dozens of engineers from Loongson International followed closely behind.
……
The other side.
Meeting room at Loongson International Headquarters.
With two big bags under his eyes and gray temples, Qu Cheng poured tea and said with a smile: "Mr. Rabitz, try the authentic Lao Ban Zhang brought by my trustee."
Beside him, Gao Yongming was assisting and said: "Mr. Qu is so grand. I have collected this old class seal for ten years, right?"
Qu Cheng glanced at him, He said calmly: "Exactly ten years."
Sitting opposite, blond, blue-eyed and thin, Rabiz was surprised and thanked in broken Chinese: "Although I don't understand tea, I have collected ten Year, then this must be a good thing."
"That's natural."
Qu Cheng replied calmly.
After hearing this, Rabbits also picked up the tea cup and tasted it carefully: "Hmm... the aroma of the tea is so strong, and there is a sweet taste after drinking it. This is what you Longguo people call Hui Gan. Really?”
“Yes, this is the kind of return that only authentic Lao Banzhang has.”
Qu Cheng said.
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 twenty yuan was said to be authentic Lao Ban Zhang.
“Ah!”
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'll order a photolithography machine from you." Qu Cheng said calmly.
Seeing that he was getting to the point, Gao Yongming also stated his purpose: "We want to order another lithography machine with a 20-nanometer process."
"Oh? Do 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 taking orders for 20 nanometers. Oh, by the way, do you think a 14 nanometer EUV lithography machine can..."
< br>Before he finished speaking, Rabitz interrupted: "I'm sorry, Mr. Gao, I can't have the final say on the EUV lithography machine. 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 task of the two is very simple, which is to delay enough time.
We will probably be done waiting for another Dutch engineer to take over the shift, so just delay it as hard as we can now.
……
Chip production workshop.
Inside the 20nm process lithography machine.
The first photomask has been installed, and the lithography machine lens 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 20 nanometer chips, photolithography has been completed by now. Directly sent for cutting and packaging inspection.
However, when using DUV lithography machines to produce 14-nanometer chips, one exposure cannot meet the demand at all, and a second exposure is required.
"Take out the first photomask and install the second photomask." Lin Tian looked at Feng Chengming and said.
Feng Chengming immediately complied.
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 to align the wafers. If the two If there is a deviation in the first point, the second exposure will damage the circuit pattern left by the first exposure, so be more careful."
After confirming that there was no problem, he looked at Feng Chengming and said: "Second. Apply the photoresist first and perform the second exposure step.”
“I understand.”
Feng Chengming 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 hundreds of thousands.
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 being 300 yuan, damaging a wafer is equivalent to a loss of 150,000 yuan.
Of course.
14nm Qingzhou processor will be more expensive!
As the lithography machine is started, deep ultraviolet light with a wavelength of 193 nanometers is continuously exposed, and the mobile platform at the bottom is also constantly moving to make up for the shortcomings of the first exposure of the circuit pattern.
A few minutes passed.
Wafer secondary exposure 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. He could not see any overlap in the pattern, but he still needed to test it.
"Expedited to send for cutting test."
Feng Chengming looked at the engineer beside him, winked and said: "Xiaolong, you take it for cutting test."
< br>“Me?”
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 that 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 said: "Then let me give it a try."
However, the seemingly simple steps caused the academician to fail several times. The difficulty is far more difficult than imagined. If there is a slight deviation, more than half of the chips will be lost directly.
"Be careful and take your time."
Lin Tian was not in a hurry, anyway, it was not his money that was wasted.
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..."
"Ha!"< br>
Lin Tian sneered, raised his head slightly and said, "My eyes are rulers. They are all experiences. Learn from them."
Another half an hour passed.
The engineer who ran to cut the wafer was currently walking in walking mode, quickly approaching 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!"
"Oh my God. ! Is this true? ”
“Is it possible to run?”
“I feel like I’m witnessing history, can someone pinch me?”
"Hahaha! Overtaking on a curve!"
The engineers exclaimed, and even Feng Chengming couldn't help but be moved, and quickly asked: "Is the power consumption excessive? How much has the performance improved compared to 28 nanometers? ?"
"The maximum operating power consumption is 18W, but it is certain that it is at least 50%!"
The scene was in an uproar.
The engineers could no longer hold back 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?
The West restricts photolithography machines?
Can the restrictions be overcome?
However, Lin Tian remained as calm as ever, without any disturbance at all.
14nm chip…
This is 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 lightly: "All the packaging and testing, if there is no problem, we will give it to you as quickly as possible. Longxing Technology will send it over. Remember, the speed must be fast and there should be no delay.”
"You, go and package the chip."
Feng Chengming continued to arrange for engineers to do it, while he himself continued to familiarize himself with wafer alignment and explore experience.
……
Dragon Kingdom Deep City.
SEG Technology Park.
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."
" It can not only 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 OK if you choose the optional product.”
“It’s good, it’s 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 back clip-on radiator, which focuses on giving users multiple choices.
Like playing games?
The radiator must be arranged.
Before 2015, Chen Xing had arranged radiators for users, which was far ahead of his 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 invested.
Now everything is ready, all it needs is that the processor chip is in place.
If the 14nm 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 10th, it’s still not too late.
Even if it is a new machine application, Chen Xing has enough connections to speed up the review. After all, he knows many academicians now.
“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.
Is it possible that...
Is it 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 to see the light through the clouds. He could not catch up with the Double Eleven Singles' Day. However, he could bring something to the Longguo mobile phone market during the Double Twelve e-commerce shopping festival. The little technology is shocking!
Let me report the results. Thousands of orders have been made and will be updated by 10,000 words in the next thirty 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 all the readers who follow up and give monthly recommendation tickets. Thank you.
