Great Power Technology

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

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

Finally, Wang Qinsheng broke the silence.

"You are so young and so promising! I couldn't believe it before. After listening to your conversation records in the past two days, whether it is ideas or techniques, you are far ahead of us old guys. I won't accept it anymore!"

"Mrs. Wang promoted me"

Ye Zhou said politely.

"It's not a compliment! We are pragmatic when doing research. We have been working on the things you came up with for almost a lifetime, but we have not yet developed a complete technology."

"Since you took it out, you deserve this honor!"

"But, having said that, I think there are still many imperfections in your vision. Come, sit down, and let's have a good chat."

As he spoke, Wang Qinsheng pointed to the seat next to him and motioned for Ye Zhou to come over. Ye Zhou couldn't refuse, so he walked to sit next to him.

"The design concept you proposed in the manufacturing process of lithography machines to replace the traditional dual synchronization with six pan-tilt synchronization is very novel! However, I didn't understand part of the one-way three-pan-tilt collaboration algorithm, and I still don't understand it. I simply followed your idea, but I don’t know if it works in practice. Can you give me a brief explanation?"

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

The idea Ye Zhou extracted from the simulator is to change the traditional dual-workbench model and instead use six precision gyroscopes to achieve synchronization of six gimbals. Each gimbal is only responsible for one-way movement to avoid errors during the reciprocating process. Very small errors caused by pauses.

However, to achieve this, the cooperation between each PTZ is required to be extremely precise. An independent control code must be set for each PTZ, and the six sets of control codes need to be related to each other, which places extremely high requirements on the algorithm.

Fortunately, after Ye Zhou absorbed the relevant knowledge of EDA, his understanding of the algorithm had reached a certain depth. At this time, he selected several key points in the design and explained them clearly to Wang Qinsheng, who nodded repeatedly.

"To be honest, I don't really understand it. I'm really not good at algorithms. But according to your explanation, it should be feasible in theory. Let's give it a try."

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

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

"First let me introduce to you the current progress."

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

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

"Second, these equipment must be used to build a wafer fab at a specific address and complete the production and inspection of the first batch of domestic chips."

"Both goals must be completed within the next 20 days, and no later than 30 days."

"So, from now on, we need to start infrastructure work. A series of infrastructure including factory facilities need to be completed within 6 days. This infrastructure will be constructed in a modular manner. Several large domestic infrastructure companies have received urgent Order, after we confirm the location, we will immediately gather the team to break ground."

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

"I have already sent you materials on the difficulties in site selection, so I will not repeat them again. Now we have three potential choices. Next, please discuss these three site selections."

Ye Zhou looked through the materials on the table, which described in detail the advantages and disadvantages of the three locations.

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

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

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

After briefly reading the materials, others have already started discussing.

"I think it is more appropriate to choose the area near the Sandouping Hydropower Station. There are abundant power resources, high security levels, developed transportation, and all materials can be easily transported. After the first phase of construction is completed, there will be no problem with subsequent expansion."

"Although Sandouping Hydropower Station has advantages, you have to know that other people's satellites are staring at that place all year round. Once we make a large-scale move, the other party can easily guess our intentions, which will trigger a chain reaction of leaks. I My personal suggestion is still to carry out construction in urban areas. As long as the confidentiality work is done well, basically there won’t be any big problems.”

"This is definitely not possible in urban areas. The project team has already had a leak risk incident before. The scale of this project is too large, and the participants must be restricted 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 at Ye Zhou and motioned for him to give his suggestions.

Ye Zhou pondered for a moment and then said:

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

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

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

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

After listening to his words, someone present asked:

"Your idea is right, but the location of Miyagi is too remote, and transportation is not convenient. The infrastructure this time is modular. So much heavy equipment needs to be transported in, and the highway capacity cannot carry it."

"You see, especially the last 16 kilometers of rural road, which is only 4 meters wide, our heavy-duty vehicles are likely to be blocked on the road. If time is delayed, the efficiency will be very low!"

Ye Zhou nodded, this is indeed a practical difficulty.

However, this is not a difficulty that is too difficult to solve.

Those present here are all experts and scholars, and they all consider problems from the perspective of objective facts. When faced with such problems, they occasionally fall into blind spots in thinking.

Like now.

They saw the factor of inconvenient transportation, but did not realize that inconvenient transportation is not an unchangeable condition.

"My idea is this. When building a factory in Miyagi, the biggest difficulty is actually the last 16 kilometers of rural roads. That being the case."

“Why don’t we start by building roads?”

The venue fell silent instantly. After a short silence, Chen Hao said to the conference secretary beside him:

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