The Literary Life of a Science Leader

Chapter 193 Neighbors engaged in lithography machines and semiconductors

evening.

Mu Jingchi drove back from school, because he was busy with a lot of things, and he also needed to hold online meetings with the entire team of major projects for research and development communication and other things.

So Mu Jingchi came back a little later this time.

When the car drove to the front of my house, I saw people having fun activities in the open space in front of my house.

After parking the car, Mu Jingchi walked down and saw two little girls dancing to the music.The little girl was about five or six years old, with cute braids. The two of them twisted their bodies from left to right, and their little hands and feet moved back and forth in sync.

There was a cheerful smile on the little face, although the dance movements were not so uniform, but both of them were very serious, looking really cute.

Looking past the two little girls, I saw a woman who was taking a video of the two little girls with her mobile phone.

Although Mu Jingchi rarely saw such scenes in this life, he had seen enough in his previous life. He was probably filming Douyin for the two little girls.

The yard of the entire villa is very large, and there is enough space in the front yard, so Mu Jingchi's parking did not affect the shooting of the three of them.

When the short song ended, the dance also ended at the same time, and the woman came over to say hello with a smile on her face.

The woman looks very young, well maintained, with a light makeup on, Mu Jingchi really can't tell the age of the other party at a glance.

Only the first feeling, looks very beautiful.

"Hello, Dr. Mu, I'm sorry to bother you." The woman came over and greeted Mu Jingchi. Her voice was very soft, with a sense of elegance from a Jiangnan water town.

"I'm a family member who lives there. My name is Ling Wanjie. I thought there was another family in this neighborhood, so I came to visit." The woman smiled very kindly, giving people a feeling of spring breeze. the other direction of the road.

"We also came over after dinner to digest food. My husband is at your house."

Mu Jingchi also showed a smile, "Thank you for your concern, we are moving here, so we should take the initiative to visit."

"It's okay, we're all neighbors, just walk around more." The woman said, beckoning two little girls over, "Ruxuan, Linglong, uncle."

"Uncle, uncle."

The two little girls' voices are very nice, and their breasts are cute.

"Hello!" Mu Jingchi squatted down and looked at the two little girls, "Welcome to my home."

"It's getting dark, let's go inside!"

Mu Jingchi led Ms. Ling and the two little girls into the house, and upon entering the door, she saw Song Xiaoyi chatting with a guest.The person chatting was also a woman, compared to Ms. Ling, she was more open-minded, as could be seen from the way she spoke to Song Xiaoyi.

Next to this woman, there were two men sitting, interjecting from time to time, looking like they were having a good conversation.

"what's the topic?"

Mu Jingchi shouted with a smile, changed his shoes at the same time, and walked in with slippers.

"We are talking about the internal facilities of this security community?" Song Xiaoyi saw Mu Jingchi coming in and immediately stood up and walked towards him, "Inside the community, there are basketball courts, football fields, and a very good cafeteria, and a kindergarten.”

"There's a whole community here!"

The reason for coming to this defense and security complex is because of Mu Jingchi. After confirming the villa, Song Xiaoyi was busy with the decoration of the facade of the house and so on.

After all, this is a national defense and security complex, Song Xiaoyi is still very relieved, so he doesn't care too much.

As Song Xiaoyi stood up, the sitting woman and the other two men also stood up at the same time.

Song Xiaoyi introduced to Mu Jingchi, "Mu, let me introduce you."

"This is Shen Fangnan, and this is Peng Xiaojie. They both live not far from each other, and are in charge of confidential projects just like you. She is Yang Yuhuan, Brother Peng's lover."

While talking, Song Xiaoyi turned her gaze to Ling Wanjie who came in behind Mu Jingchi, who said, "We met outside."

"Nice to meet you."

Mu Jingchi greeted everyone with a smile, "It stands to reason that I should be the one to visit everyone, but time is too tight and business is busy, please bear with me."

"You don't need to be so polite, everyone is doing research, and they can understand each other's situations."

The one who spoke was Peng Xiaojie, he seemed to be in good spirits, his eyes were shining, his hair was not thick, but it was not thin either.While speaking, he hugged the little girl Linglong who rushed over.

"Yeah, we are all colleagues, we know everything, and we don't have so many polite words."

After talking a few words, it was possible to get a rough idea of ​​their personalities, so we all sat on the sofa and chatted together.

The women did not come to disturb them. The three women were with the children.

Since dinner was already eaten, Song Xiaoyi didn't have to be busy in the kitchen. Song Xiaoyi took the women and children to visit the second and third floors, and then went back to the backyard to play.

"Brother Shen, Brother Peng, what project are you working on?"

After casually chatting a few words about the community and life, the three of them gradually got closer, and because Shen Fangnan and Peng Xiaojie were both older than Mujingchi, so Mujingchi was also called On brother.

"I work on lithography machines, and you, Brother Peng, work on the third-generation semiconductor silicon carbide and gallium nitride."

Mu Jingchi suddenly became respectful and stretched out his thumb, "It's amazing."

Shen Fangnan waved his hands to Peng Xiaojie, "I can't compare to you."

"We are catching up in both aspects, catching up with the progress of foreign countries. You opened up a new field of material research at a young age, and you are much stronger than us."

Mu Jingchi smiled modestly and said, "It's just luck."

"Excessive modesty is pride!" Peng Xiaojie did not admit that Mu Jingchi was lucky.

"How are Brother Shen and Brother Peng doing in terms of lithography machines, SiC and GaN? There should be a lot of results, right?" Mu Jingchi inquired a little, but this is not a state secret.

What can be said on this occasion is only some general directions, or the results made, but what is involved in confidentiality is more detailed data or craftsmanship.

"Not ideal!"

Shen Fangnan shook his head, "You should be familiar with the problems of lithography machines. There are many difficulties, and foreign countries have blocked our technology and equipment. We are still far away from the most advanced EUV7nm."

Speaking of lithography machines, Shen Fangnan was also a little depressed. The whole of China started too late in this regard.As for chips, the larger the scale and the better the performance, the cheaper it will be. Huaxia cannot use its usual low price advantage to open up the market, so it can only keep investing money in it.

"Now silicon chips seem to have entered a bottleneck. Quantum tunneling will occur after 5nm. Now everyone is looking for new materials. Although graphene and carbon nanotubes are theoretically feasible, there has been no relevant breakthrough."

"Does this leave us some time to catch up?"

Shen Fang smiled bitterly and said, "Dr. Mu, you are also a person who produces materials. You should know that other countries will come up with it at some point."

"However, even if we have time to develop, we can't catch up in other aspects!"

Although the quantum tunneling effect has caused a bottleneck in the chip's manufacturing process, it does not mean that the performance of the chip has encountered a bottleneck.

In fact, the performance improvement of the CPU mainly depends on the improvement of the logic design, and the process improvement is secondary.

In terms of technology alone, the process is not the only improvement. For example, in 2011, Intel began to use "3D transistors" to produce CPUs, which reduced CPU power consumption by half.

And now Xue Qikun, an academician of the Chinese Academy of Sciences, led an experimental team composed of the Institute of Physics of the Chinese Academy of Sciences and the Department of Physics of Tsinghua University, which has also overcome the quantum anomalous Hall effect, giving a new direction to the development of chip technology.

Its application in electronic devices can overcome a series of problems caused by current computer heating and energy consumption, bring another revolution to the semiconductor industry, and even make giant Galaxy computers as portable as iPads.

Mu Jingchi didn't know whether to laugh or cry, "Brother Shen, you're thinking too far. You're in charge of the research and development of lithography machines, not the entire Huaxia semiconductor industry. Don't you think too much?"

"He, it's not that he can't see that China's semiconductor industry is being harvested by foreign countries. All related semiconductor industries in South Korea, Japan, Europe and the United States are sucking blood from us."

Peng Xiaojie answered Mu Jingchi's question.

Regarding Huaxia's semiconductor industry, Mu Jingchi also has a deep sense of helplessness. Although he is not engaged in related semiconductors, Huaxia's semiconductor industry is indeed helpless.

After so many years of development, Huaxia has made great progress in many industries, some of which have narrowed the distance with foreign countries, and some have even reached the forefront of the world.

Among so many industries, the chip industry is undoubtedly very conspicuous.

The annual chip imports of more than 3000 billion US dollars really make China helpless. This is a visible gap.In high-end industries such as the mobile phone industry, the automobile industry, personal computers, and servers, chips are all monopolized by foreign countries.

This is why Huawei HiSilicon has boosted morale so much after it produced the Kirin chip!
"Sorry, couldn't help it!"

Shen Fang raised his emotions hard, "Every time we talk about lithography machines, it is always inevitable to involve the chip industry. There is no way."

As he spoke, he laughed again.

"If there are material talents like you in China's semiconductor industry and open up a research direction for semiconductor materials, maybe we can achieve cornering overtaking, and even if we can't, it will give us more time to develop."

Although they are all materials, the materials Mu Jingchi works on have little to do with semiconductor materials, they are in different directions, and the theory of dislocation cannot be applied to semiconductor materials.

"Actually, my material research can be regarded as a roundabout strategy!"
