The Technology Tree of Xueba

Time flies, and it has been a full month since Xinghuo Technology purchased the Graphene Chip Research Institute from the Chinese Academy of Sciences.

Sure enough, as Academician Tian Kai said, Xingyu Technology only spent 500 million yuan to buy this research institute in a package.

During this period of time, Zhou Yu handled the company's business remotely, and has been researching graphene chips with Academician Tian Kai.

Today, he is discussing the graphene wafer production plan with Feng Yunde, and his girlfriend Chen Jin came to the institute to find him.

Zhou Yu's face was covered with black ashes, like a coal worker. He showed his white teeth, and only then did he realize that the smile on his face was getting stronger.

Chen Jin said with a distressed expression, How did you become like this?

She immediately took out the handkerchief and wiped Zhou Yu's face carefully.

It's okay, these are graphite powder, why do you have time to come here. Zhou Yu said with a smile.

Today is the weekend and I take turns off. It happens to be June 1st. I'll come to see you.

Chen Jin wiped Zhou Yu's face clean, took a plastic food box, and said, Today is your birthday, and I personally made a birthday cake for you. Children's Day birthday is easy to remember.

Zhou Yu took out the birthday cake and took a bite, the crispy taste filled his mouth.

He said happily: It's delicious, any food you make is delicious.

Pay attention to the impact, we single dogs have been hit by 10,000 critical points. Feng Yunde walked over probing, and couldn't help but say.

He is 1.7 meters tall, with a thin build, his expression is very dull, and he looks stupid.

Feng Yunde, you are not single, aren't you chasing Jiang Weiwei now? Zhou Yu teased.

He is the ultimate...dog~beast.

Chen Jin blurted out the words, but then retracted them.

Go to work! I'll go back and take care of Bajie Education Network, and we'll talk at night. Chen Jin bid farewell.

Start working, record the 1648th experiment, observe the growth plan of the graphene transistor, and see if a theoretical graphene wafer can be produced. Zhou Yu ordered loudly.

Feng Yunde's eyes became sharper, and he immediately observed the holographic image of the reactor, and judged the situation inside the reactor through the sensor output data.

This reaction furnace is his invention, and its shape is very similar to a blast furnace for ironmaking.

Graphite is ionized by a high-energy electric field at the furnace mouth to form carbon ion clusters. After the carbon ion clusters are supplemented with electrons by the electron beam in the middle layer of the reaction furnace, they become graphene molecular colloids. After passing through a special magnetic field at the bottom of the reactor, the carbon ion clusters are piled up into billions of graphene molecules. Chips made of transistors.

This is the graphene wafer growth method researched by Feng Yunde.

The graphene in the reaction furnace quickly completed the reaction. Feng Yunde took out the wafer and used the equipment to quickly judge whether the wafer met the requirements.

He shook his head in frustration and said: This experiment failed again, the processing material of the graphene chip, the graphene wafer we have failed so many times.

How soon can we manufacture graphene chips? Weiwei said that if I become a level 9 expert in the company, she will consider marrying me.

Zhou Yu thought, Jiang Weiwei wanted to escape the entanglement of the ultimate dog licking beast, and said a goal that he could hardly achieve.

We started to summarize the data of this failure. I believe that failure is the mother of success, and we will succeed soon. Zhou Yu encouraged.

He really knew that the graphene chip would be successful soon, because the technology tree in Zhou Yu's mind, the leaf of the graphene chip was about to bloom.

Zhou Yu knew that summing up some experience again, he communicated more with Feng Yunde and Academician Tian Kai, the graphene chip would definitely make a breakthrough.

After Feng Yunde sorted out the failure data of graphene wafer production, he and Zhou Yu went to find Academician Tian Kai together.

When they came to Academician Tian Kai's office, they saw that Tian Kai was sitting on a chair, with a holographic image showing a graphene chip magnified tens of thousands of times in front of him.

He is constantly adjusting the position of different transistors on the graphene chip.

This work is the most critical coding work of graphene chips and the core technology of chip design.

Tian Kai saw Zhou Yu coming, and he praised: Mr. Zhou, you are the fastest learning person I have ever met. You have only studied with me for more than a month, and you have already mastered most of the knowledge of graphene chips, which is better than I used to. The researchers who have been with them for a year have a lot of knowledge.

Genius is always different. For me, this knowledge is really not difficult, and I can learn it as soon as I learn it.

Zhou Yu showed a confident expression, thinking to himself, I have mastered more graphene chip technology than you think.

He has now learned how to pretend to be a real academic master. No matter what achievements a genius makes, others will only be surprised and will not doubt it.

Academician Tian, ​​Dr. Feng and I have designed thousands of experiments to solve hundreds of difficulties in making graphene wafers, but there are still some details that we haven't grasped well, so I come to ask you for advice. Zhou Yu said respectfully.

He then recounted the problems found in the production of graphene wafers.

Tian Kai is worthy of being an academician, and he is also an academician who studies graphene. After reading the data, he immediately found out where the experiment went wrong, and discussed with Zhou Yu and Feng Yunde how to design a better experiment.

Zhou Yu listened to Tian Kai's explanation, and the technology tree in his mind was constantly raining golden raindrops, and soon reached a critical point. The leaf of graphene chips bloomed, and he harvested the manufacturing methods of graphene chips, including the manufacturing process of graphene chips .

Academician Tian, ​​Dr. Feng, I think our theory is perfect enough, but many manufacturing failures are due to impurities mixed in the graphene. Zhou Yu said in an affirmative tone.

This is impossible. We use graphite with a purity of 99.9999%. After ionization and magnetic field screening, the purity of graphene is already very high. Feng Yunde said in disbelief.

The problem lies in the ionization step. When the graphite powder is ionized, the air is also ionized, and a large amount of impurities are mixed into the graphite ion cluster. Zhou Yu pointedly said.

Feng Yunde slapped his thigh, annoyed: Why didn't I think of such a simple problem, graphite is ionized, and air can also be easily ionized.

Come on, let's conduct an experiment in a vacuum and take a look at the results of the experiment.

Feng Yunde immediately ran out of the office after speaking, ready to test this idea.

Zhou Yu was very confident. Instead of verifying with Feng Yunde, he asked Tian Kai, Academician Tian, ​​have all the other processes of the graphene chip been completed?

Tian Kai frowned and said, The graphene chips I research are different from ordinary silicon-based chips.

Considering that the strength of Huaxia chip processing lies in etching and the shortcoming of photolithography, the processing of my design graphene chip only needs to be etched, that is, the etching accuracy should be greatly improved.

Graphene wafers are processed into graphene chips, and the wafers require three main processes: etching, coding, and packaging.

It costs 500,000 yuan to manufacture a square millimeter graphene wafer by moving the graphene transistor in the laboratory, and a total of 5 million yuan is required to complete the wafer processing.

In the past month, I have spent 500 million yuan to verify only the two processes of successful encoding and packaging. The etching process is too demanding, but the theory does not need to be changed.

For the verification chip I made in the laboratory, the etching step was slowly ground with a hydrogen atom beam.

Industrial processing is extremely difficult, and there is no etching machine with the required precision in the world.

Zhou Yu recalled the technical information etched on the technology tree, which also required the use of a 0.1-nanometer hydrogen atom beam to modify a 1-nanometer graphene transistor.

Feng Yunde pushed open the door of the office and said pleasantly: It's really the influence of impurities. Come and see the first batch of industrially processed graphene wafers coming out of the oven.

It really worked. Tian Kai stood up excitedly.

It's good to succeed. Zhou Yu stood up calmly.

On the way they went to the laboratory, Feng Yunde chattered about the process of his experiments.

After listening to Mr. Zhou's speculation, I used vacuum ionization to process a batch of graphene wafers. The graphene wafers released from the furnace have reached a usable level, but they are not theoretically perfect wafers.

I also improved the magnetic field screening method to remove most of the impurities, and I will be able to produce perfect graphene wafers.

Zhou Yu waited for the reaction in the reactor to complete, and soon the reactor officially spit out a one-square-meter graphene wafer.

After detailed testing, Feng Yunde clenched his fists and said excitedly: The graphene wafer data is perfect, our experiment is successful, and we can directly use it to process graphene chips.
