Chapter 163 We want to make progress so much!
When the words "SOC God Chip is completed" fell, it was no less than a heavy hammer hitting the hearts of everyone present.
“It’s done!”
A photolithography engineer repeated it.
In a flash.
Warm applause and cheers erupted in the clean room of the lithography machine.
“Bah bang bang——”
“It’s done! Domestic SOC chip!”
“Using a 48nm DUV lithography machine to create a 14nm SOC system-on-chip, we succeeded! ”
“Hahaha, far ahead!”
"I feel like I have witnessed history, and the historians of the Dragon Kingdom will definitely record that today, January 20, 2015, the God chip that officially competes with Snapdragon chips, Orion chips, and Apple A-series chips came out. This is the first Domestic SOC system-on-chip! "
"Oh my God! I finally felt the sentence in the textbook, one small step for me, one giant step for the world. This chip is one small step for us. But it is a big step in the development of Longguo Chip!”
The engineers in the clean room lamented that there are not many opportunities to witness history, and it may be the only one in this life.
No one here expected that Longguo Semiconductor Chip could develop so rapidly in just one year.
In early 2014, Longguo’s mobile phone technology companies were strangled by Gaotong, threatening to share patented technology with them and increase the sales price of Snapdragon chips by 70%.
Why does it dare to open its mouth like a lion?
Two words, monopoly!
Orion and Apple chips are internally supplied chips, and Longguo manufacturers can only choose chips from Snapdragon and MediaTek.
On the one hand, there are high-end performance chips, and on the other hand, there are inferior chips that have not yet completely transformed and cannot be used in the copycat market. Gaotong Company is actually a monopoly.
Because of monopoly, it is unscrupulous.
No matter which country you are in, as long as a certain industry or field is monopolized, the most upstream company will have absolute pricing power. You must accept whatever price others say.
Don’t accept?
Then the only option is slow death!
With the official advent of the SOC God chip that can fully compete with Snapdragon chips, the Sword of Damocles that has been hanging over the heads of Dragon Kingdom manufacturers for several years has finally been destroyed. Now they can look up to the sky. A long roar:
"Dragon Kingdom Chip, stand up!"
The cheers lasted for several minutes, and Chen Xing could not hide his excitement.
For Longguo Semiconductor Chip, this is a leap forward, but for Longxing Technology Company, it is crucial and a powerful tool to challenge the West.
When the cheers subsided slightly, Chen Xing's breathing became rapid, and he looked at Feng Chengming and said, "Mr. Feng, I would like to ask, what is the yield rate of a single 12-inch semiconductor silicon wafer?"
The yield rate of semiconductor silicon wafer production is related to the cost of a single chip.
The diameter of a 12-inch semiconductor silicon wafer is 30CM. If the die is cut according to the size of 1.6×1.6CM, 232 die chips can be cut out. If the yield is 95%, then 221 die can be produced. About 100 finished chips.
At present, Shin-Etsu Chemical Group and Shenggao Group occupy a total of 62% of the global semiconductor silicon wafer market. Their quotations for 12-inch semiconductor silicon wafers range from 3,000 to 5,000 RMB.
According to the top price of 5,000 yuan, even if the yield rate is 100%, and not counting processing costs, the cost price of 232 pure bare dies will be 21 yuan. If the yield rate is 90%, then the cost price will be 21 yuan. The price will increase by 3 yuan to 24 yuan. If you sell one million mobile phones, you will have to spend an additional 3 million yuan!
Therefore, after confirming that the production was successful, Chen Xing couldn't wait to ask about the yield rate of semiconductor bare chips. This is related to the cost price and is also a part of profit improvement.
“We haven’t tested everything yet. Now that Mr. Chen has spoken, we will conduct urgent testing to see what the yield rate is.”
Feng Chengming responded with a smile.
He left the equipment control area, came to the machine that cut the bare wafers, and brought in all the wafers that had not yet been tested for testing.
"Good product."
"Good product."
"Good product."
Because there are already examples of chip parameters, the equipment detection speed is also very fast , the chip will pass directly without defects.
Duan Yongping thought of something and said with some confusion: "No, the maximum operating power consumption is 15W. I remember Mr. Chen said in your press conference that the operating power consumption of the SOC God chip is 16W. How can there be a deviation?" < br>
He only heard that the actual chip deviated from the design parameters, causing power consumption to increase, but he had never heard of a decrease in power consumption.
Strange!
So weird!
Chen Xing and Ren Guofei are tacitly understanding that they have not chosen to show off the new semiconductor silicon wafer technology.
Even if I say it, I won’t say it now. Although the engineers present are bound by the contract, who can guarantee that they will not betray the "domestic alliance" in exchange for profits?
There is a saying in "Das Kapital" that when the profit reaches 100%, some people dare to take risks; when the profit reaches 200%, they dare to risk the guillotine; and when the profit reaches 300 %, they will trample all laws in the world.
The more these "outsider" engineers know, the higher the risk of betraying the domestic alliance. Never underestimate the darkness of human nature.
Chen Yong was also very nervous. He laughed and said: "It is a good thing that the chip reduces power consumption. It uses less power to do more things and can also effectively reduce heat generation. No matter how it is reduced."
“Having said that, even if the power consumption is reduced, the number of calculations is increased. Isn’t this a bit strange?”
Duan Yongping looked at the 450 billion operations per second and continued to be confused.
He vaguely remembered Chen Xing saying that the SOC God chip has 400 billion operations per second. Only by connecting a second independent chip can the number of operations be pushed to 700 billion. But what about the extra 50 billion now? ghost?
The 450 billion operations per second is almost catching up with the 500 billion operations per second of the Apple A9s Bionic chip.
Power consumption decreases and computing power increases. How do you explain this?
It is impossible to name "God". God is really secretly working to add a BUFF to this batch of chips, right?
Chen Yong still waved his hand and said nervously: "Maybe there is an error in the EDA software simulation verification. In any case, this is a good thing. If you make a mistake, you will be wrong, hahaha!"
"Maybe God really shows his spirit."
Ren Guofei joked with a smile.
Already approaching the age of seventy, he has never been as relaxed as he is today, and he can't help but joke with other bosses.
“The results are out.”
While several bosses were chatting, Feng Chengming had already calculated the die data.
After a half-second pause, he announced the specific yield rate: "A 12-inch semiconductor silicon wafer can cut out 232 SOC God chips, of which 3 are scraps, 8 have poor circuit performance, and the remaining chips All qualified. ”
Of the 232 chips, 11 failed, which is equivalent to a yield rate of 95%, which is already an extremely high level in the industry.
The most important thing is that this semiconductor silicon wafer has been exposed and etched four times, and the difficulty has skyrocketed several times.
“Such a high yield rate.”
Ren Guofei’s eyes flashed with surprise. He thought 80% would be good, but he didn’t expect it to be 95%!
Duan Yongping and Chen Yong were also surprised. The latter stuttered a little: "How much more?"
"95%!"
Feng Chengming confirmed again. With a yield rate of 95%, Chen Yong was so excited that he was trembling with excitement. The 48nm DUV lithography machine produced 14nm chips with a yield rate of 95%. This is simply turning waste into...
No!
This is turning a treasure into a treasure!
Nowadays, Kunpeng Company is engaged in infrastructure construction and Rice Company operates overseas markets. In addition to harvesting the star economy, blue and green factories may also increase investment in chip production.
Expand the business scope, cooperate with Longxing Technology Company, and jointly share the cake in the semiconductor field, the future is bright!
Chen Xing silently calculated the cost of the chip in his mind. Since it is a self-produced semiconductor silicon wafer, it is equivalent to using the manufacturer's price to produce it.
The cost of a 12-inch semiconductor silicon wafer is about 800 yuan. Based on 221 dies with a 95% yield rate, the price of a single die is 3.6 yuan.
If a series of production costs such as photoresist, packaging, and photolithography machine production are added, the cost price of a single SOC God chip should be around 7 yuan, and the maximum will not exceed 10 yuan.
10 yuan for a 14nm chip, what is this concept?
Take the original Kaitian baseband chip as an example. TSMC charges 32 yuan for each OEM chip. This is still a 28nm chip. If it is a 14nm process chip, it is no exaggeration to say that they dare to Charge 50 yuan!
10 yuan and 50 yuan, the cost price has dropped by a full 40 yuan, which is equivalent to a profit increase of 40 yuan. It can be seen how profitable localization is. This piece of cake is definitely enough for everyone.
Just as everyone was immersed in the joy of high yield, Lin Tian interrupted: "Don't be too happy too early. If I do it, I can achieve a 95% yield rate, but you guys..."
< br>He glanced at Feng Chengming and the lithography engineers of the blue and green factory, and continued: "In less than ten days and a half, if you damage hundreds of semiconductor silicon wafers, you may not be able to get in."
Feng Chengming: "... ..."
Blue and Green Factory Engineer: "..."
Although it is the truth, it hurts people's self-esteem too much.
"This yellow hair has started again." Chen Xing sighed secretly in his heart. Although Lin Tian was technically excellent, as marked on his attribute panel, he was too arrogant.
IQ is sufficient, but EQ is worrying.
However, because of Chen Xing’s platform and seeing Lin Tian’s photolithography skills, Chen Yong was not angry because his photolithography engineer was belittled. Instead, he humbly asked for advice:
< br>"Chief Lin, do you have any way to help everyone get started with photolithography quickly?"
The words just finished.
Engineers from the blue and green factories echoed.
"Chief Lin, please teach us. We will accept you as our teacher. From now on, we will serve you tea and water, and introduce you to people."
"Is there a shortcut? Brother Lin."< br>
“I really want to ask for advice, I want to make progress so much.”
Feng Chengming’s old face was also brave, and he echoed: “Yes, Chief Lin, we all want to make progress too much, you must Teach us, and if you have anything to do in the future, we will definitely handle it for you.”
Who doesn’t want to make progress among scientific researchers?
Once you master the core technology, it will be a meteoric rise, and you may even be included in the history books.
"I'm telling you very clearly." Lin Tian looked at the humble look of everyone, paused for a moment and continued: "There is no shortcut to quadruple exposure. You can only practice slowly and by feeling. But, I have You can rest assured here that within two months, all of you will be photolithography masters.”
His words are equivalent to a promise, a promise to teach them all.
Although Feng Chengming is old, his reaction speed is not slow at all. He quickly said: "I will feel relieved if Chief Lin teaches in person. I have some basics in lithography. You can teach me first. I Then teach other kids.”
The word "little friend" really means relying on one's old age and showing off one's old age.
Do other lithography engineers dare to say no?
Not to mention that Feng Chengming is older, but the key is that he is still an academician of the Dragon Academy of Sciences. Who dares to compete with him for the position of "disciple of photolithography"?
The lithography engineers of the blue and green factory do not dare to compete for the position of the top disciple. The lithography engineers of the blue and green factory will not give up the position of the second disciple or the third disciple.
"Since Mr. Feng is first, then I will be second. I also hope that Chief Lin will not dislike my stupid talent."
"I have had a good memory and learning ability since I was a child. Extremely strong, what about me being the third?”
“Then I am the fourth!”
“No, no, I am the fourth, my photolithography skills are better than yours!”
>
"Zhang Laosan, you are probably itchy? When did you get better at photolithography than me? When I was in school, my grades were always higher than yours!"
"Going to school is going to school. Now that I have entered society, Angkor, times have changed, so I have to learn the fourth one!”
The lithography engineers in the blue and green factory were all talking and arguing over the ranking.
In the field of photolithography technology, there is now an unfathomable teacher teaching them, and each of them wants to make progress too much.
However.
That’s when.
Chen Xing raised his volume several times and said, "Everyone, stop for a moment. I will definitely teach you the quadruple exposure technology, but the top priority now is to produce the open-space baseband chip first."
"Because I will ship 1 million units of Longxing X2 mobile phones on the 25th, and will also sell 50,000 units of Bright X1 and 50,000 units of Geek X1. As for the current chip production, SOC God Chip is not in a hurry and will continue mass production first. Sky baseband chip.”
After being reminded, everyone also realized that the most urgent need now is the Sky baseband chip, not the SOC God chip.
The output of 100,000 pieces per day can fully meet the delivery demand.
Hearing this, Lin Tian also pressed his hands and said lightly: "Did you hear it? My president has spoken. He will produce Kaitian baseband chips first. When the shipping period has passed, I will I’ll teach you the quadruple exposure technique step by step.”
“Then I’ll stay and help.”
Feng Chengming didn't plan to leave either, thinking he had to learn how to leave again.
He did not want to miss this once-in-a-lifetime teaching opportunity.
After other lithography engineers heard this, some of them were already quick to move production materials to prepare for chip production.
To leave a good impression on Chen Xing, isn’t this an indirect way of establishing a good relationship with Lin Tian? Humanity and sophistication are so crucial!
A moment later.
They all started working independently.
Feng Chengming glanced at the bare chips, then looked at Chen Xing and said, "Mr. Chen, are these bare chips packaged and packaged now, or will they be packaged and shipped to your factory later?"
"Encapsulate it now."
Chen Xing responded with a smile, then looked at CEOs Ren Guofei and Duan Yongping and said, "How about you guys go to my production factory? Witness the launch of the first Geek X1? "
"Haha, I can't refuse Brother Chen's invitation. Let's go to Longxing Technology's production factory together?" Ren Guofei looked to his side. Several bosses said.
"That's just right."
Duan Yongping also smiled and responded quickly: "Not only can we witness the launch of Geek X1, but we can also visit the scale of the factory."
"Don't mention it yet. , I haven’t gone in to see it, then we can set off, right?”
Chen Yong agreed.
"What about me?"
Feng Chengming asked quickly, his eyes showing hope.
Chen Xing saw that they were all interested in Geek X1 and invited him again: "Then let's go there together. If we encounter any problems, we can work out a solution together."
