Technology: To go to college, turn in controlled nuclear fusion

Director Zhang

personally handled the certificate of the No. 3 Research Institute for Jiang Fan, so that he could enter and exit

in the future! He also gave Jiang Fan his contact information

! "Jiang Fan, if you have any needs in the laboratory in the future, you can find me!"

"Thank you, Director Zhang!" Jiang Fan thanked him!

The chip laboratory is divided into two parts of research, one part is the research of the lithography machine, and the other part is the research of the silicon wafer, the material of the chip!

Qiao Lao took Jiang Fan to the lithography machine laboratory first.

He said

to a huge machine, "Jiang Fan, this is a lithography machine for making chips

!" "Uncle Qiao, how many nanometers can this lithography machine be precise?"

"21 nanometers!" "21 nanometers? so bad!"

Jiang Fan couldn't help frowning and said!

"

This is still from the beautiful country to spend 1 billion to buy back, and this machine is currently the most sophisticated lithography machine in the Dragon Kingdom...

Qiao Lao said, a touch of shame appeared on his face! Chip

technology is the shortcoming of the Dragon Kingdom, such as mobile phones, computers, TV dramas, and so on, the high-performance chips needed by the Dragon Kingdom can only rely on imports

! The reason why the beautiful country chose chips for this economic sanction is to take this problem into account!

In the commercial field, the most sophisticated chip independently developed by the Dragon Kingdom has only reached 27 nanometers

These crude low-performance chips can only be used in some simple equipment! The

precision of the chip depends on the precision of the lithography machine in the final analysis.

If the precision of the lithography machine can only reach 21 nanometers, then the highest performance of the developed chip will reach 21 nanometers.

Jiang Fan took a brief look, this old lithography machine is very different from the 7-nanometer lithography machine that the system rewards in his mind, and it is not of the same magnitude

at all! Moreover, the parts in this lithography machine are also very old, and there is no use value at all!

The reason why the beautiful country resells the eliminated garbage to the dragon country.

They affirmed that Long Guo would not be able to develop a more precise lithography machine at all according to the principle of this old

lithography machine! Because the lithography machine has reached less than 15 nanometers, its design principle has undergone tremendous changes.

Not only did the beautiful country earn money from the dragon kingdom, but also deliberately misled the dragon kingdom about the research direction of

the lithography machine! However, Jiang Fan did not immediately point out the problem of the lithography machine, he needed to understand the research institute and the current overall situation clearly, and then make a specific plan

! When Qiao Laozheng introduced the design theory of this lithography machine to Jiang Fan, Jiang Fan directly interrupted him!

Uncle Qiao, can you take me to see the silicon wafer equipment?" Qiao

Lao was not angry at Jiang Fan's interruption, but took

Jiang Fan to a laboratory next to him! At this time, there was a scientific researcher in the laboratory, wearing a white scientific research uniform, doing research

! When the scientific researcher turned around, Jiang Fan found that she was actually a female researcher

, and she looked a little familiar! I saw that her facial features were exquisite, the corners of her eyes were slightly raised, and she looked a little charming.

Although she was wearing work clothes, she could already see her convex and concave figure

! When she saw Qiao Lao, she said suspiciously

! "Uncle, didn't you go back with back pain, why did you come again!"

Jiang Fan next to her instantly knew who she

was! She was Qiao Shan's niece

Qiao Yifei! At the beginning, Qiao Shan specially asked Qiao Yifei to accompany him to visit the campus of Huaqing University in order to let Jiang Fan go to Huaqing University!

He also had a nosebleed

! But then again, it was precisely because of Qiao Yifei that Jiang Fan received the system reward for staying up late, so that he could usually stay up late to do research!

And now he can be with Chu Ruoxi again, it was Jiang Fan who mistakenly thought that the online name Little Wild Cat was Qiao Yifei.

By mistake, they were made.

If he said that, Qiao Yifei would still be his nobleman

!Jiang Fan said to Qiao Yifei politely!"Senior Sister Qiao Yifei, you are also here!" Qiao Yifei

noticed that Jiang Fan, who was wearing a white research uniform, took a closer look and said with some surprise! "

Jiang Fan

? Why did you come here!

" "Jiang Fan, I brought it here, and I will study chip technology with us in the future!"

Qiao Yifei was inexplicably a little excited when she heard this.

Since the last time she went to Longke, she saw Jiang Fan's outstanding performance in the Freshman Traditional Challenge, and his figure often appeared in her mind!

Although her best friend Xia Xiaoyu told her that Jiang Fan had a girlfriend, she still had some indescribable feelings for Jiang Fan in her heart!

She sometimes wondered to herself, a woman who had talked about more than ten boyfriends, would be tempted by a little boy who had just turned eighteen years old

Originally, after all these days of self-repair, she had almost forgotten

Jiang Fan! But who knows, Jiang Fan suddenly appeared in front of her again, the kind of small flame that was about to be extinguished by her, this will suddenly burn again!

"Yifei, what are you in a daze? Didn't you hear two shouts?"

Qiao Shan said angrily.

"Ahh

I was thinking about the experimental data just now!" Qiao Yifei hurriedly quibbled, where did she think about the experimental data, it was clear that she was thinking about Jiang Fan's things again!

"If you are too tired, go back and rest, this silicon wafer purification technology is not a day or two can be successful

!" "No, no, I'm not tired at all

!" Qiao Yifei hurriedly said, she finally saw Jiang Fan, how could she go back immediately!"

Okay, you and Jiang Fan have both met, so I won't introduce you! You tell Jiang Fan, to what extent is the current research on silicon wafers in the laboratory?"

"Hmm

!" Qiao Yifei couldn't ask for it, but with her uncle here, she couldn't be too enthusiastic

! So she restrained her emotions and

said! "Jiang Fan's little brother..."

"Senior Sister Qiao Yifei, you can just call me Jiang Fan!" Jiang Fan said helplessly!

He really couldn't stand it, when Qiao Yifei called his name, he added a suffix of 'little brother

'! Qiao Yifei heard Jiang Fan's words, he didn't know why, he made up some pictures in his mind, and finally couldn't help but cover

his mouth and laugh! Qiao Shan saw Qiao Yifei covering his mouth and laughing, and said unceremoniously!

"You have to be attentive and serious when you work, you know?"

Qiao Yifei was reprimanded by Qiao Lao, and immediately restrained his smile.

So I talked to Jiang Fan seriously about silicon wafers!

"At present, the purity of silicon element extraction in our research institute is 98.99%, but it is still a little unstable..."

And the further you go, the more difficult it is to break through 0.1%!
