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 big project team to communicate with R&D and other things.

So this time Mu Jingchi came back a little later.

When the car drove to the front of the house, I saw that there were people in the open space in front of the house doing happy activities.

After parking the car, Mu Jingchi walked down and saw two little girls dancing dynamically to the music. The little girl looked like she was about five or six years old, with cute pigtails, and the two of them writhed their bodies left and right, and their little hands and feet also moved left and right in sync.

The little face is full of cheerful smiles, and although the dance moves are not so uniform, both of them are very serious, and they look really cute.

Looking over the two little girls, I saw the woman who was holding a mobile phone and shooting a video for the two little girls.

Although Mu Jingchi rarely sees such a scene in this life, he has seen enough in his previous life, and he should be 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 the parking of Mu Jingchi did not affect the shooting of the three of them.

When the song was over and the dance was over, the woman greeted her with a smile on her face.

The woman looks very young, well-maintained, and wears light makeup, and Mu Jingchi really can't tell the other party's age at a glance.

Only the first feeling, looks beautiful.

"Hello Dr. Mu, I take the liberty of interrupting. The woman walked over and greeted Mu Jingchi, her voice was very glutinous, and she had a sense of grace in the water town of the south of the Yangtze River.

"I am a family member who lives over there, my name is Ling Wanjie, and I thought that there was another family in this community, so I came to visit. The woman smiled very kindly, giving people the feeling of a spring breeze, and pointed in the other direction along the road as she spoke.

"We also had dinner to eat, and my husband was at your house. ”

Mu Jingchi also smiled, "Thank you for your concern, we are here and should take the initiative to visit." ”

"It's okay, everyone is a neighbor, just move around. As the woman spoke, she beckoned and invited the two little girls over, "Ruxuan, Linglong, call uncle." ”

"Uncle, uncle. ”

The two little girls' crisp voices are very good, and they are cute and cute.

"Hello!" Mu Jingchi half-squatted down and looked at the two little girls, "Welcome to my house." ”

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

Mu Jingchi led Ms. Ling and the two little girls into the house, and when they entered the door, they saw Song Xiaoyi chatting with the guests. The person chatting is also a woman, and she is more hearty than Ms. Ling, which can be seen from the way she talks to Song Xiaoyi.

Next to the woman, two other men were sitting, interjecting from time to time, looking like they were having a good time.

"What are you talking about?"

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

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

"It's a whole community here!"

I came to this national defense and security community because of Mu Jingchi, and after confirming the villa, Song Xiaoyi was busy with the decoration of the façade of the house, and he really didn't completely look at the entire community.

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

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

Song Xiaoyi introduced Mu Jingchi, "Mu, I'll introduce you." ”

"This is Shen Fangnan, this is Peng Xiaojie, they both live next door not far away, and they are the same as you are the person in charge of the confidential project. She is Yang Yuhuan and Brother Peng's lover. ”

Song Xiaoyi, who was speaking, turned her gaze to Ling Wanjie, who came in behind Mu Jingchi, and the latter said, "We have met outside. ”

"Fortunately, fortunately. ”

Mu Jingchi greeted everyone with a smile, "It stands to reason that I should be visiting you, but the time is too tight and the affairs are busy, so please bear with me." ”

"Don't be so polite, everyone is engaged in research, and we can understand each other's situation. ”

It was Peng Xiaojie who spoke, he seemed to be in good spirits, his eyes were bright, and his hair was not thick, but it was not sparse. As he spoke, he picked up the little girl Linglong who rushed over.

"Yes, we are all peers, we all understand, and we are not so polite. ”

After saying a few words, I almost figured out the external personalities of several people, so everyone sat on the sofa together and chatted.

The women didn't come to disturb them, and the three women were with the children.

Because he had already eaten dinner, he didn't have to be busy in the kitchen, so Song Xiaoyi took the woman and the child to the second and third floors for a walk, and then returned to the backyard to play.

"Brother Shen, Brother Peng, what are you doing?"

casually chatted a few words about the topic of the community and the topic of life, and the three of them slowly got closer, and because Shen Fangnan and Peng Xiaojie were both older than Mu Jingchi, Mu Jingchi also called his brother.

"I'm doing lithography machines, and you, Brother Peng, are doing third-generation semiconductors, silicon carbide and gallium nitride. ”

Mu Jingchi suddenly stood in awe and stretched out his thumb, "Amazing." ”

Shen Fangnan waved his hand to Peng Xiaojie, "It's not comparable to you." ”

"We're catch-ups on both fronts, catching up with progress abroad. You've opened up a whole new field of materials research at a young age, and you're much better than we are. ”

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

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

"Now in terms of lithography machine and SiC and GaN, how are Brother Shen and Brother Peng doing? There should be a lot of achievements, right?" Mu Jingchi inquired a little, this is not a state secret.

What can be said in this case is just some general directions, or the results made, but what touches on the secret is more detailed data or process and so on.

"Not ideal!"

Shen Fangnan shook his head, "You should also know a little about the problem of lithography machine, there are many difficulties, and foreign countries have blocked our technology and equipment, and it is still far from the most advanced EUV7nm." ”

Speaking of lithography machines, Shen Fangnan's mood was also a little low, and the whole Huaxia started too late in this regard. And the larger the scale of the chip, the better the performance, the cheaper, Huaxia can not use the consistent low price advantage to open the market, so it can only keep investing money in it.

"Now silicon chips seem to have entered a bottleneck, after 5nm there will be a quantum tunneling effect, and now everyone is looking for new materials, graphene and carbon nanotubes, although theoretically feasible, but there has been no relevant breakthrough. ”

"There's still time for us to catch up, right?"

Shen Fangnan smiled bitterly, "Dr. Mu, you are also engaged in materials, you should know when other countries will come out." ”

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

Although there is a bottleneck in the chip manufacturing process due to the quantum tunneling effect, 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.

For example, in 2011, Intel began to use "3D transistors" to produce CPUs, which reduced CPU power consumption by half.

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

When applied to electronic devices, it can overcome a series of problems caused by the current computer heating and energy consumption, bring another revolution to the semiconductor industry, and even make the giant galaxy computer as portable as an iPad.

Mu Jingchi couldn't laugh or cry, "Brother Shen, you're thinking too far, you're in charge of the research and development of lithography machines, and you're not in charge of the entire Huaxia semiconductor industry, so you're thinking too much, right?"

"He, it's not that he can't see that the Huaxia semiconductor industry is being harvested abroad, and all the related semiconductor industries in South Korea, Japan, Europe and the United States are sucking blood on us. ”

Peng Xiaojie answered Mu Jingchi's question.

For Huaxia's semiconductor industry, Mu Jingchi also has a deep sense of helplessness, although he is not engaged in related semiconductors, but Huaxia's semiconductors are indeed very helpless.

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

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

The annual chip import of more than 300 billion US dollars really makes China helpless, which is a visible gap. In the mobile phone industry, the automobile industry, personal computers, servers and other high-end industries, chips are monopolized by foreign countries.

This is also the reason why Huawei's HiSilicon Semiconductor has boosted morale so much after making Kirin chips!

"Sorry, I can't help it!"

Shen Fang's difficulty was to mention his emotions, "Every time I talk about the problem of lithography machines, it is inevitable that it will be involved in the chip industry, and there is no way." ”

As he spoke, he laughed again.

"If we have material talents like you in the semiconductor industry in China and open up a research direction for semiconductor materials, maybe we can still achieve corner overtaking, and even if we can't, we will have more time to develop. ”

Although they are all materials, the materials that Mu Jingchi is engaged in 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!"
