The Technology Tree of Xueba

Chapter 36: Wafer manufacturing success

Few days passed, and it has been a month since Spark Technology purchased the Graphene Chip 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.

Zhou Yuyu has been processing the company's business remotely during this time, and has been studying graphene chips with Academician Tian Kai.

Today he is discussing the graphene wafer production scheme with Feng Yunde. His girlfriend Chen Jin came to the institute to find him.

Zhou Zhouyu's face was a layer of black and gray, like a coal worker. He exposed his white teeth, only to find that his smile was getting stronger.

Chen Jin said with a distressed expression: "How do you become like this?"

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

"It's okay, these are graphite powders. Why do you have time to come here?" Zhou Yu said with a smile.

"Today is my weekend off. It happens to be June 1. I'll come and see you."

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

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

He said happily: "It's delicious. You can eat anything you like."

注意 "Pay attention to the impact, our single dogs have been hit 10,000 times." Feng Yunde came forward with a probe and couldn't help saying.

He is 1.7 meters tall, with a thin figure, a dull expression, and a dull look.

"Feng Yunde, you are not a single dog, are you chasing Jiang Weiwei now?" Zhou Yu teased.

"He is the ultimate ... dog ~ beast."

Chen Jin blurted out and closed it back to his mouth.

"You work! I'll go back and watch the Bajie Education Network, and we'll talk again at night." Chen Jin said goodbye.

"Begin work, record the 1648th experiment, observe the growth plan of the graphene transistor, and see if it can produce a theoretical graphene wafer." Zhou Yu commanded loudly.

云 Feng Yunde's eyes became sharp, and he immediately observed the holographic image of the reaction furnace, and judged the situation inside the reaction furnace through the output data of the sensor.

反应 This reaction furnace is his invention, and its shape is very similar to that of an iron-making blast furnace.

Graphite is ionized by the high-energy electric field at the mouth of the furnace into carbon ion groups. After the carbon ion groups are supplemented by electrons in the middle layer of the reaction furnace, they become graphene molecular colloids, which reflect a special magnetic field at the bottom of the furnace. Wafer consisting of transistors.

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

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

He shook his head in frustration: "This experiment failed again. We have failed graphene chip processing materials, graphene wafers so many times.

多 How long before we can make graphene chips, Wei Wei said that I became a 9th-level expert in the company, and she would consider marrying me. "

Zhou Yu thought, Jiang Weiwei was to escape the entanglement of the ultimate licking dog and beast, and uttered a goal that he could hardly accomplish.

我们 "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.

真的 He really knows that the graphene chip will soon succeed, because of the technology tree in Zhou Yu's mind, the leaf of the graphene chip is about to bloom.

Zhou Yu knows to summarize some experiences again. He and Feng Yunde and academician Tian Kai have more exchanges, and the graphene chip will definitely make a breakthrough.

云 Feng Yunde sorted out the data on the failure of graphene wafer production. He and Zhou Yu went to the academician Tian Kai together.

来到 They came to the academician Tian Kai's office and saw Tian Kai sitting in a chair, displaying a graphene chip with tens of thousands of times in front of him in a holographic image.

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

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

Tian Kai saw Zhou Yu's arrival and he applauded: "Zhou Zhou, you are the person who has met the fastest learning efficiency. After only studying with me for more than a month, I have mastered most of the knowledge of graphene chips, which is more than I used to. Researchers who take a year are very knowledgeable. "

"Geniuses are always different. For me, this knowledge is not difficult, and it will be as soon as I learn it."

Zhou Zhouyu showed a confident expression and thought to myself that I have more graphene chip technology than you think.

He has now learned how to pretend to be a true learner. No matter what the genius does, others will only be surprised and not doubtful.

"Academician Tian, ​​Dr. Feng and I have designed thousands of experiments to solve hundreds of difficulties in the manufacture of graphene wafers, but there are still some details that I am not sure about. Please come to ask you." Zhou Yu said respectfully.

随后 He then repeated the problems found in the production of graphene wafers.

Putian Kai is indeed an academician or an academician of 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. The golden raindrops on the technology tree kept falling in his mind, and soon reached the critical point. The leaf of the graphene chip bloomed. He harvested the manufacturing method of the graphene chip, including the manufacturing process of the graphene chip. .

"Academician Tian, ​​Dr. Feng, I think our theory is perfect enough. Many times the manufacturing failed because of impurities in graphene." Zhou Yu said with a positive 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 incredibly.

"The problem arises in the ionization step. At the same time as the graphite powder is ionized, the air is also ionized, and a large amount of impurities are mixed into the graphite ion group." Zhou Yu saw the blood channel with a pinch.

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

快 "Hurry up, let's run the experiment under vacuum and see the results."

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

Zhou Zhouyu was very confident. He did not go to verify with Feng Yunde, but asked Tian Kai: "Academician Tian, ​​have the other processes of the graphene chip been completed?"

Putian frowned: "The graphene chip I studied is different from the ordinary silicon-based chip.

Considering that the advantages of Huaxia chip processing are etching and the disadvantages are lithography, I only need to etch the graphene chip for processing, which means that the etching accuracy must be improved a lot. UC Reading www.uukanshu.com

Graphene wafers are processed into graphene chips. The wafers need to be etched, coded, and packaged.

It takes 500,000 yuan to make a square millimeter of graphene wafers by moving graphene transistors in the lab, and a total of 5 million yuan is needed to complete wafer processing.

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

The verification chip I made in the laboratory, this step is slowly grinding with a hydrogen atom beam.

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

Zhou Zhouyu recalled the technical information etched on the technology tree, which also required a 1 nm graphene transistor to be modified with a 0.1 nm hydrogen atom beam.

云 Feng Yunde opened the door of the office and was pleasantly surprised: "It is really the influence of impurities. Let's watch the first batch of industrially processed graphene wafers come out."

"Really succeeded." Tian Kai stood up excitedly.

"Success is just fine." Zhou Yu calmly stood up.

On their way to the laboratory, Feng Yunde chattered and talked about the process of his experiment.

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

I also improved the way of magnetic field screening, removing most of the impurities, and will definitely produce perfect graphene wafers. "

Zhou Yu waited for the reactor to complete the reaction, and soon the reactor spit out a square meter of graphene wafers.

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