Director Zhang personally applied for Jiang Fan’s certificate for Research Institute No. 3 to facilitate his future access!

And he even gave his contact information to Jiang Fan!

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

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

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

The chip laboratory is divided into two parts of research, one is the research of photolithography machines, and the other is the research 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 a photolithography machine for making chips!"

"Uncle Qiao, how precise is this photolithography machine in nanometers?"

"21 nanometers!"

"21 nanometers? So bad!"

Jiang Fan couldn't help but frown and said!

"I only bought this from Beautiful National Flower for 1 billion. This machine is currently the most sophisticated photolithography machine in the Dragon Kingdom..."

Mr. Qiao said, with a look of shame on his face!

Chip technology is Longguo’s shortcoming. For high-performance chips needed for mobile phones, computers, TV series, etc., Longguo can only rely on imports!

The reason why the beautiful country chooses chips for this economic sanctions is to take this issue into consideration!

In the commercial field, the most precise chip currently independently developed by Longguo has reached 27 nanometers!

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

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

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

Jiang Fan briefly checked and found that this old lithography machine was very different from the 7-nanometer lithography machine that the system rewarded in his mind. They were not at the same level at all!

Moreover, the parts in this photolithography machine are also very old and have no use value at all!

The reason why Beautiful Country resold the discarded garbage to Long Country.

They were sure that Long Guo would not be able to develop a more precise photolithography machine based on the principles of this old photolithography machine!

Because the lithography machine has reached within 15 nanometers, its design principles have undergone tremendous changes.

Beautiful Country not only made money from Long Country, but also intentionally misled Long Country’s research direction on photolithography machines!

It’s really heartbreaking!

However, Jiang Fan did not immediately point out the problem with the lithography machine. He needed to first understand the overall situation of the institute before making a specific plan!

When Mr. Qiao was introducing the design theory of this photolithography machine to Jiang Fan, Jiang Fan interrupted him directly!

"Uncle Joe, 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 nearby laboratory!

At this time, there is a scientific researcher in the laboratory, wearing a white scientific research uniform and doing research!

When the researcher turned around, Jiang Fan discovered that she was actually a female researcher, and she looked familiar!

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

Even though she is wearing work clothes, you can already see her curvy figure!

When she saw Mr. Qiao, she said doubtfully!

"Uncle, isn't your back pain gone? Why is it here again?"

Jiang Fan next to her instantly knew who she was!

She is Qiao Yifei, Qiao Shan’s niece!

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

It even gave him a nosebleed!

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

Moreover, he is now able to be with Chu Ruoxi again because Jiang Fan mistakenly thought that the online name of Little Wildcat was Qiao Yifei.

By a combination of circumstances, they succeeded.

If that's the case, Qiao Yifei is still his noble person!

Jiang Fan said to Qiao Yifei out of politeness!

"Senior Qiao Yifei, you are here too!"

Only then did Qiao Yifei notice that Jiang Fan was wearing a white research uniform. She took a closer look and said with some surprise!

"Jiang Fan? You...why are you here!"

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

When Qiao Yifei heard this, she felt a little excited for no reason.

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

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

Sometimes she wonders to herself, how can a woman who has had more than ten boyfriends fall in love with a boy who has just turned eighteen?

It turned out that after these days of self-repair, she had almost forgotten about Jiang Fan!

But who would have thought that Jiang Fan suddenly appeared in front of her again, and the small flame that she had almost extinguished would suddenly burn again!

"Yifei, why are you in a daze? Didn't you hear me after you shouted twice?"

Qiao Shan said angrily.

"Ah! I...I just thought about the experimental data again!"

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

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

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

Qiao Yifei said quickly, she finally met Jiang Fan, how could she go back right away?

"Okay, you and Jiang Fan already know each other, so I won't introduce you! Can you tell Jiang Fan how far the laboratory's silicon wafer research has gone?"

"Um!"

Qiao Yifei responded eagerly, but with her uncle here, she couldn't be too enthusiastic!

So she controlled her emotions and said!

"Little brother Jiang Fan..."

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

He really couldn't stand it, so when Qiao Yifei called his name, she added the suffix "little brother"!

When Qiao Yifei heard Jiang Fan's words, she didn't know why, but some pictures came up in her mind, and in the end she couldn't help covering her mouth and laughing!

Seeing Qiao Yifei covering her mouth and laughing, Qiao Shan said rudely!

"You have to be attentive when working, you know?"

Qiao Yifei was scolded by Mr. Qiao and immediately stopped smiling.

So I told Jiang Fan seriously about silicon wafers!

"Currently, the purity of silicon extracted by our institute is %, but it is still a little unstable..."

"The company with the highest purity of silicon wafers on Blue Star is Niu Niali. Currently, there is still a 1% technology gap between us and them..."

Jiang Fan knows very well that even though the purity is only 1%, the technical content required is very high.
Chapter completed!
