Chapter 33 The Problem of Carbon Nanotube Purification
Li Xiangda never expected that not only he received the email, but even Diao Yuanbai also received the email!
"Are the others..."
Sure enough, one after another called.
All that is said is one thing.
They received the email and also received Huasheng Eda!
Although some people are complacent and feel that they are the only ones and have not spread it out, Li Xiangda can guess that almost all semiconductor companies in trouble have Huasheng Eda.
Isn’t this the real-life version of the chip hero after Chicken Nuggets, French Fries, and Ice Cream?
"Mr. Li, I found the built-in document." XCMG opened the document and everyone turned their eyes over.
"The other party said that Huasheng EDA was distributed to us for free for half a year, and we would choose to cooperate after we survive this crisis. Moreover, the price given by the developer is 10% less than the price we used to cooperate with Siemens!"
Li Xiangda cried with joy, "Is God opening his eyes?"
He knew very well what Huasheng eda meant.
From the perspective of Patta alone, this is a life-saving straw!
"Mr. Li... can we do it anymore?" The employee under his command said stutteringly.
Li Xiangda committed the crime by blowing it, "Why don't you do it? His grandma, we not only have to do it this time, but also do it beautifully! Don't the three major manufacturers like to play sanctions? Although we don't have that ability, we can disgust them from other places. Contact the marketing department, and we will directly turn the market overseas this time!"
"Okay!" The people present were full of energy.
Li Xiangda once again contacted his previous brother-in-law.
After receiving the call, they all rushed over.
Diao Yuanbai has a good complexion and has solved a huge problem. How can he be in a bad mood?
"Mr. Diao, I think you still remember the content of that email."
Diao Yuanbai focused his attention, "Of course, he hopes we can unite and be united to the outside world!"
"Everyone, although we don't know who helped us behind the scenes, what I hope is that we can really do as he said, unite and be united to the outside world. After experiencing this crisis, I also figured out that the semiconductor industry is related to the entire China, not a company." Li Xiangda was strong and powerful.
Almost everyone understands how powerful Huasheng EDA developers are.
Giving up the software cost for half a year is still much lower than that of Sanwai's software, so it is not an exaggeration to say that it is doing charity.
But it is also true, making them understand that the other party did not lend a helping hand because of money, but really wanted to tie everyone together.
Huasheng Eda has appeared in the eyes of the public, and he can't stop him even if he wants to. Of course, Chen Yuan did not think about hiding anything. The countless press releases on the Internet attracted the attention of the public.
"Last night, several semiconductor companies received external assistance. A software called Huasheng eda solved the current dilemma of China. It is reported that Huasheng eda is an integrated chip design software with a minimum process that can support 1nm chip design, but its development company has not yet surfaced!"
Penguin News: "Huasheng EDA saved the domestic semiconductor industry. Who is his developer?! Download Penguin News to browse the full text."
Worship News: "Huaxia's independently developed EDA has surpassed overseas. Will the national semiconductor industry be replaced with HSDA in the future?"
uc News: "Shocked! The developer of Huasheng EDA turned out to be him..."
Among the hot searches on the entire network, the most popular keyword is Huasheng!
And netizens were also caught in endless discussions.
"We have studied Huasheng EDA in a factory. It's so awesome. The technology is better than the EDA developed by the three major manufacturers! I can only say thanks to this chip man. If he hadn't taken action, I would have been laid off."
"I'm now purely doubting whether Huasheng EDA was developed in China. This is so outrageous. Integrated EDA software, just that technology, I guess several major Western countries can't get it."
"It's exaggerated, I can only say that it can't be done in a short period of time. But brother, what do you want to express? What are the aliens given?"
"I suspect there is a conspiracy here, brothers."
"Your sister conspiracy, the West is blocking our necks, and I wish we could die. People unconditionally offer Huasheng Eda at this time. That's not life-saving? Just talk about this motivation, no matter whether he is a Chinese or not, even if he is an islander, then his cliff is on our side!"
There are more and more discussions about Huasheng, and of course, the most curious one is his developer.
At that time, Chen Yuan had just finished taking a shower and received a call from Zhang Xiaolong.
"Old Chen, you are not authentic. You can get a free trial for half a year, and the price is lower than that of our HiSilicon. I doubt you are from our side." Zhang Xiaolong quipped on the other end of the phone.
Chen Yuan wiped his head with a towel and smiled, "Brother Zhang, look at what you said, what size is our HiSilicon? It can be compared with those small businesses."
"Don't worry, I don't mean to blame you. Not only that, I admire you more and more." You must know that in Zhang Xiaolong's heart, Chen Yuan has always been a guy who has no money and will not let go. If you catch you, you will be cheated. If you don't make a big profit, you won't let go. But this time he became so generous.
He also knew that Chen Yuan was not only to help these companies, but also to make the domestic semiconductor industry flourish.
Is Chen Yuan really the kind of broad-minded person?
No, his heart is bleeding now.
Mr. Li, you must be more agitated. I will cheat you when I get fatter one day.
In the next few days, Chen Yuan stayed in the laboratory.
Although this time, more problems will surely be thrown away in the future, especially in the current situation where the situation is so tense, and every day cannot be delayed.
However, the research and development of carbon-based chips has a long way to go, and it is not as simple as Chen Yuan imagined.
The initial realization of carbon nanotubes is only a technical breakthrough, but if you want to achieve mass production in the future, you will first face a problem, that is, how to efficiently purify carbon elements in carbon nanotubes.
Chen Yuan summoned everyone, including several technical senior officials from HiSilicon.
Chen Yuan walked to the projection cloth and said seriously, "Everyone, thank you very much for your hard research during this period, but now we are facing a new problem, that is, how to purify carbon elements."
"I think you all know that carbon primer tubes are a semiconductor material with excellent performance. Connecting metal to both ends can generate a boundary voltage. This boundary voltage allows current to flow through one direction, similar to semiconductor transistors in ordinary chips."
"To make a simple analogy, a ball can roll freely on a plane, but if it is rolling on a slope, it may not be that easy."
"There may be two kinds of slopes. One is the shape of a concave character, which is the lower middle and the higher sides. If the ball wants to flow from one side to the other, it must be raised which part of the concave is raised. When the middle part and both sides are on the same horizontal plane, the ball can pass smoothly. This requires a relatively large thrust to lift the middle part. The usual method is to add an electric field above the middle part."
"The second case is the shape of a convex character, that is, the middle is high and the two sides are low. In this case, a repulsive force is needed to add to make the middle part concave and form a plane as high as the two sides, so that the ball can pass smoothly on this plane."
"One on both sides is called the source, that is, the input, the other is called the drain, the output, and there is a door in the middle. If this door cannot be opened, the current cannot pass. Once a certain voltage is applied to the door, the door can be opened easily to realize the current flow."
"Whether it is carbon nanotubes or silicon semiconductors, it uses this principle."
Chen Yuan paused for a moment and took a sip of tea.
"A carbon-based chip replaces the flow channel in the middle with carbon nanotubes. At the same time, the source and drain on both sides are no longer doped with the silicon material used in the silicon-based chips before, but a special metal. Using the boundary voltage between this special metal material and the carbon nanotube, a semiconductor transistor can be made."
"But the problem arises here. We cannot effectively purify carbon elements. If it is just a single study, we can develop the best carbon nanotubes in detail, but what if it is mass production?"
After listening to Chen Yuan's long speech, everyone present fell into thought.
No matter how good the technology is, no matter how good the carbon nanotube is, it is meaningless to make a chip if it cannot be mass-produced.
If it is stuck on purification, it is difficult to effectively implement n-type transistors and p-type transistors based on carbon nanotubes.
These are the basic parts for manufacturing integrated circuits.
"Carbon is quite lively and it is indeed very difficult to purify. However, we can try to purify and arrange carbon nanotubes based on small molecules and aqueous solvents." Academician Chen Qing expressed his thoughts.
He walked to the stage, pulled the projection cloth, opened the blackboard, and then wrote relevant data and molecular deconstruction on it with a water pen. "The principle of this purification is mainly to use small molecules to adsorb the surface of carbon nanotubes, and the purification of carbon nanotubes is achieved through chromatography or biphasic extraction."
Chen Yuan stood aside and thought. At this time, he almost like everyone else, put aside his own identity and personality and transformed into an extremely serious attitude.
"I have actually thought about this method, but the current yield is low, and the purity is generally lower than 99.9%. However, we can try to optimize it in the purification process."
"It's true." Chen Qing nodded. He didn't care whether his proposal would be accepted. In fact, this is the case when studying high-tech. Only by constantly proposing solutions and constantly trial and error can we embark on the right path.
Even though Chen Qing knew the disadvantages of this purification method from the very beginning, he still wanted to try it.
After all, he is not the only one who is struggling for this at this moment.
There is also Chen Yuan and everyone who looks at him.
