Director Zhang personally handled the No. 3 Institute ID for Jiang Fan to facilitate his future entry and exit!

And he also gave his contact information to Jiang Fan!

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

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

Afterwards, Mr. Qiao took Jiang Fan to the chip laboratory!

The chip laboratory is divided into two parts, one is the study of lithography machines, and the other is the study of silicon wafers, the material of the chip!

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

He said to a huge machine!

"Jiang Fan, this is the lithography machine for making chips!"

"Uncle Qiao, how accurate is this lithography function to this nanometers?"

“21 nanometers!”

"21 nanometers? That's so bad!"

Jiang Fan couldn't help but frown and said!

"It was only bought from Beautiful Country for 1 billion. Currently, this machine is the most sophisticated lithography machine in Long Country..."

As Mr. Qiao said, a look of ashamed appeared on his face!

Chip technology is the shortcomings of Long Kingdom, such as high-performance chips required for mobile phones, computers, TV series, etc. Long Kingdom can only rely on imports!

The reason why Piaoliang Country chose chips for this economic sanction is to consider this issue!

In the commercial field, the most precise chips independently developed by Longguo have only reached 27 nanometers!

These rough low-performance chips can only be used in some simple devices!

The precision of a chip ultimately depends on the precision of the lithography machine.

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

Jiang Fan briefly checked it. This old lithography machine is far from the 7-nanometer lithography machine rewarded by the system 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 have no use value at all!

The reason why the beautiful country bought the eliminated garbage to the Long Country.

They are sure that Long Guo could not study a more precise lithography machine according to the principles of this old lithography machine!

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

The beautiful country not only earned money from the Long Country, but also deliberately misled the Long Country's research direction on lithography machines!

It's really a pity!

However, Jiang Fan did not immediately point out the problem of lithography machines. He needed to understand the research institute and the overall situation clearly before making 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?"

Mr. Qiao 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 looked familiar!

I saw that she had delicate facial features, slightly raised corners of her eyes, looking a little charming.

Especially her proud breasts, although she was wearing work clothes, she could already see her convex figure!

When she saw Mr. Qiao, she said in confusion!

"Uncle, have you been back from a pain in your back? Why are you here again?"

Jiang Fan next to him instantly knew who she was!

She is Qiao Shan’s niece Qiao Yifei!

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

He even had nosebleeds!

But then again, it was precisely because of Qiao Yifei that Jiang Fan received the system rewarded stay up late capsule, allowing him to stay up late to do research!

Moreover, when he is able to be with Chu Ruoxi again, Jiang Fan mistakenly thought that the online name Little Wild Cat was Qiao Yifei.

By chance, they made them successful.

If that is the case, Qiao Yifei will still be his noble person!

Jiang Fan said politely to Qiao Yifei!

"Senior Sister Qiao Yifei, you are here too!"

Only then did Qiao Yifei notice that Jiang Fan, wearing a white research suit, looked carefully and said in surprise!

"Jiang Fan? You... why did you come here!"

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

When Qiao Yifei heard this, she felt a little excited.

Since the last time she went to Longke, she saw Jiang Fan’s outstanding performance in the New Year’s Traditional Challenge, and his figure often appears in her mind!

Although her best friend Xia Xiaoyu told her that Jiang Fan had a girlfriend, she still had a little bit of a sense of unexplained feelings for Jiang Fan!

Sometimes she wonders herself that a woman who has had more than ten boyfriends would be moved by a boy who was just eighteen years old?

After these days, she has almost forgotten Jiang Fan!

But who knew that Jiang Fan suddenly appeared in front of her again, and the small flame that was about to be extinguished by her suddenly started to burn again!

"Yifei, why are you stunned? Didn't you hear me shouting twice?"

Qiao Shan said angrily.

"Ah! I...I just wanted to experiment with the data!"

Qiao Yifei quickly argued that she was not thinking about experimental data, it was clearly just thinking about Jiang Fan again!

"If you are too tired, go back and rest. This silicon wafer purification technology cannot be successful in one day or two!"

"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 know each other, so I won't introduce it! Tell Jiang Fan about how far has the silicon wafer research in the laboratory been studied?"

"Um!"

Qiao Yifei responded with great help, but with her uncle, she could not show too much enthusiasm!

So she restrained her emotions and said!

"Little Brother Jiang Fan..."

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

He really couldn't stand it. When Qiao Yifei called his name, he added the suffix of "little brother"!

When Qiao Yifei heard Jiang Fan's words, for some reason, she made up some pictures in her mind, and finally couldn't help but cover her mouth and laughed!

Qiao Shan saw Qiao Yifei covering her mouth and laughing, and said bluntly!

"You have to be serious when working, do you know?"

Qiao Yifei was scolded by Qiao Lao and immediately restrained her smile.

So I told Jiang Fan seriously about silicon wafers!

"Currently, the purity of silicon element extraction in our institute is 98.99%, but it is still a bit unstable..."

"The highest purity of silicon wafers on Blue Star is 99.99% of the Beautiful Country. Currently, we are still 1% different from them..."

Jiang Fan knew very well that although he was only 1% purity, the required technical content was very high.

And the later it goes, it is very difficult to break through 0.1%!
