Simulation: Great Power Technology

Ye Zhou followed Chen Hao into the conference room. He recognized many familiar faces among the attendees, including Wang Qinsheng, a grandfather of the domestic semiconductor industry.

Seeing him come in, everyone stood up and motioned to him, Ye Zhou stood there awkwardly, not knowing what to say for a while.

Finally, Wang Qinsheng broke the silence.

"Young and promising! I couldn't believe it before. After listening to your conversation records in the past two days, whether it is thinking or technology, it has surpassed our old men by too much.

"Old lady Wang praised me..."

Ye Zhou said quickly and politely.

"It's not a compliment! We focus on seeking truth from facts in our research. We have been working on the things you have come up with for almost a lifetime, but until now, we haven't come up with a complete technology."

"Since you took it out, you can afford this honor!"

"However, having said that, I think there is still a lot of incomprehension in your vision. Come, sit down, and let's have a good chat..."

While talking, Wang Qinsheng pointed to the seat beside him and signaled Ye Zhou to go over. Ye Zhou couldn't refuse, so he walked over to sit next to him.

"The design concept that you proposed in the manufacturing process of the lithography machine to replace the traditional double synchronization through the six-head synchronization is very novel! However, I did not understand part of the collaboration algorithm of the one-way three-head synchronization, and now I am also I just did it according to your idea, I don't know if it works or not, can you give me a brief explanation?"

The so-called synchronization actually refers to the synchronization of the two workbenches inside the lithography machine. The two workbenches must always move at the same speed, and the error must be controlled within 2nm. When entering the sub-nanometer level etching, The synchronization rate is required to be less than one hundredth of a nanometer.

The idea that Ye Zhou extracted from the simulator is to change the traditional mode of the dual worktable and use six precision gyroscopes to achieve the synchronization of the six gimbal. Very small errors caused by pauses.

However, to do this, the cooperation between each gimbal is required to be extremely precise, and an independent control code must be set for each gimbal, and the six sets of control codes need to be related to each other, which requires extremely high algorithms.

Fortunately, after absorbing the relevant knowledge of eda, Yungui's understanding of the algorithm has reached a certain depth. At this time, he chose a few key points in the design to explain clearly to Wang Qinsheng, which made him nod again and again.

"To be honest, I don't really understand it. I'm really unprofessional in terms of algorithms, but according to your explanation, it should work in theory. Let's try it out."

"Yes, this is not the topic of today. The main thing we want to discuss is the issue of quickly building a factory and putting it into production. Come on, Xiao Chen, organize a meeting."

Hearing Wang Qinsheng's words, Chen Hao nodded, turned on the projection screen in the middle of the conference room, and said:

"Let me introduce you to the current progress."

"After 16 days of preparation, our preliminary preparations for the key components of the chip have been basically completed, and the remaining difficulties will continue to be improved in the construction. Now we need to do two things."

"First, expand the existing production capacity, produce key equipment including but not limited to lithography machines, etching machines, and ion implanters, and complete the assembly."

"Second, we must use these equipment to build a fab at a specific location and complete the production and inspection of the first batch of domestic chips."

"Both of these goals must be completed within the next 20 days, and no more than 30 days at the latest."

"So, from now on, we need to start the infrastructure work, and a series of infrastructure projects, including plant facilities, need to be completed within 6 days. This time the infrastructure construction will be modularized, and several large domestic infrastructure companies have received urgent Order, the team will break ground as soon as we determine the site."

"What we want to determine today is the question of location."

"The previous materials about the difficult points of site selection have been sent to you, so I won't repeat them. Now we have three potential options. Next, please discuss these three sites."

Ye Zhou flipped through the materials on the table, which described the pros and cons of the three sites in detail.

The first is located near the largest hydropower station in China, with abundant power resources, tight security and high security.

The second is located in a small town in the southwest, with a limited power supply, but there is an independent hydropower station that can be requisitioned. It is also located in the 100,000-strong mountain, and it is highly concealed. The only disadvantage is that the traffic is too congested, which has a great impact on efficiency.

The third is the construction in the urban area, the risk of leakage is high, but the human and equipment resources are abundant, which can greatly improve the efficiency.

After a brief look at the material, others have already started a discussion.

"I think it is more appropriate to choose the vicinity of Sandouping Hydropower Station, where there are abundant power resources, high security level, developed transportation, and convenient transportation of various materials. After the completion of the first stage of construction, there is no problem with subsequent expansion."

"Although Sandouping Hydropower Station has advantages, you must know that other people's satellites are staring at that place all the year round. Once we have a large-scale action, the other party can easily guess our intentions, which will trigger a chain reaction of leaks. I My personal suggestion is urban construction, as long as the confidentiality work is done well, there will be basically no major problems.”

"The urban area is definitely not acceptable. The project team has already had a leak risk incident before. The scale of this project is too large, and the participants must be limited to a small geographical area for unified management. There is this near the Miyagi Hydropower Station. condition."

......

Everyone debated for half an hour, but could not reach an agreement. Chen Hao pointed to Ye Zhou and motioned him to give suggestions.

Ye Zhou pondered for a moment, then said:

"First of all, we have to make it clear that our fundamental purpose of this project is not mass production, but technical verification, so we don't need to consider the issue of subsequent expansion at all, but confidentiality is the first need. This One point, do you agree?"

Everyone in the conference room nodded, so Ye Zhou continued:

"In my opinion, Sandouping Hydropower Station was the first to be excluded. The reason has also been mentioned. We cannot block the eyes of satellites. Urban construction is also not feasible. Humans are the most complex animals, and the more people involved, the more , the more difficult it is to control the risk of leakage.”

"So, my point of view is the same as this, uh, this comrade, I must choose the Miyagi Hydropower Station in Shiwanda Mountain!"

After listening to his words, one of the people present asked:

"Your idea is right, but Miyagi's geographical location is too remote, and transportation is inconvenient. This time the infrastructure is modular, so much heavy equipment has to be transported in, and the road transport capacity cannot be carried at all."

"Look, especially the last 16-kilometer country road, with a width of only 4 meters, our heavy-duty vehicles are likely to be stuck on the road. If the time is delayed, the efficiency will be very low!"

Ye Zhou nodded, it was indeed an actual difficulty.

However, this is not a difficult difficulty to solve.

All present are experts and scholars, and they all consider problems from the perspective of objective facts. When faced with such problems, they occasionally fall into a blind spot of thinking.

like now.

They saw the factor of inconvenience, but they didn't realize that inconvenience is not an unchangeable condition.

"My thoughts are like this. In fact, the biggest difficulty in building a factory in Miyagi is the last 16 kilometers of rural roads. Since that's the case..."

"Why don't we start by building roads?"

The venue fell silent in an instant, and after a brief silence, Chen Hao said to the conference secretary beside him:

"Call an enlarged meeting, get involved in the infrastructure team, and immediately evaluate the feasibility of the plan!"
