The rise of nanometers

Huang Xiuyuan, Lu Xuedong and others were immersed in the process of research and development of nanowires.

Through Xiao Yingnan, he asked Lin Baijie to set up a textile equipment company, and asked to recruit a group of textile equipment designers and engineers, as well as recruit a group of embroidery experts.

Although Lin Baijie felt baffled, he still implemented Huang Xiuyuan's instructions.

Through various channels and the attraction of high salaries, hundreds of textile equipment designers, engineers, and more than a dozen senior experts in embroidery were quickly recruited.

Soon a research institute called "Special Textile Equipment Research Institute" was quietly established within Suiren Company.

Among the engineers who were recruited, Xia Qiuzhen was appointed as the chief engineer. He was a well-known textile equipment designer in China. While working for his old employer, he chose to switch to the newly established Suiren Company because he had different ideas from his boss.

Although he didn't know why Suiren Company wanted to develop textile equipment, Xia Qiuzhen didn't care. He just wanted to develop the most advanced textile equipment.

After more than a week of working together as a team.

He and several other engineers and experts were called to a very hidden research institute.

Zhang Jingjian, a semiconductor microcircuit designer, turned on the multimedia in the conference room and projected a set of pictures on the screen.

Everyone who participated in the meeting started whispering among themselves after seeing these pictures.

"Quiet." Zhang Jingjian pointed to the picture of the curtain: "I will assign a task. What we need to design now is textile equipment with these types of knots."

Xia Qiuzhen didn't take it seriously: "Gong Zhang, this is very simple."

"Don't be so quick to seal the deal. Let me tell you your requirements." Zhang Jing opened the next page and saw a series of requirements.

The cross-sectional diameter of threads used for textiles is 0.5 nanometers to 2 nanometers; the minimum textile precision is not less than 20 nanometers, and the number of structures is not less than 10 billion...

After seeing these requests, Xia Qiuzhen was dumbfounded and turned around: "Gong Zhang, are you sure you are not joking?"

"What do you think? Would the company pay to invite you here just to make a joke?" Zhang Jingjian asked.

Xia Qiuzhen scratched his head: "Well...that's not what I meant. I just think that designing this kind of equipment is completely useless because there are no 0.5-2 nanometer wires at all."

"I don't know if there are other places, but the company does have this kind of line." Zhang Jingjian explained briefly.

"Are there 0.5 to 2 nanometer lines?" Xia Qiuzhen was very surprised.

Zhang Jingjian did not explain this aspect in depth, but asked: "If we want to achieve weaving and fine control, what conditions need to be met?"

A group of engineers began to discuss, and soon they started talking about some questions.

One of the engineers asked: "How strong are these nanowires?"

Zhang Jingjian took out a document and handed it over. It showed the cross-sectional diameters of silicon nanowires, phosphorus nanowires, copper nanowires, and boron nanowires, as well as the related strengths.

"Both ordinary cotton thread and steel wire are available."

"The strength is not bad. High-strength silicon nanowires and copper nanometers have better operability."

"If it's this strong, it should be able to pass through weaving."

Then Xia Qiuzhen also raised a question: "Because the accuracy requirements are very high, a super balance system, a very good servo motor, and control software may be needed."

"Can it be delivered using domestic parts?" Zhang Jingjian also asked a key question.

Xia Qiuzhen discussed with other engineers for a while before giving an answer: "If we use domestic parts and want to ensure accuracy, we can only rely on slow work and careful work."

"Based on the area of ​​a single block and processing 10 billion structures, how much time is estimated to take?"

Xia Qiuzhen took out a pen, made rough calculations on the scratch paper for a few minutes, and gave an answer: "If it is six-thread knitting, depending on the complexity of the pattern, 200,000 to 400,000 structures can be knitted in one hour, and 100 knitted structures can be completed. 100 million structures will require 25,000 to 50,000 hours.”

Stopping here, Zhang Jingjian shook his head: "It's too slow."

Xia Qiuzhen thought for a while and came up with another plan: "If we use longitude and latitude lines and add jump stitches, the efficiency can be increased to tens of millions of structures per hour, but the pattern needs to be set well."

Tens of millions of structures per hour is barely enough. Weaving 10 billion structures would take about a thousand hours, or about 42 days.

"If we add more needle channels, can the efficiency be further improved?"

Xia Qiuzhen shook his head: "Unless a more advanced control system is adopted, the accuracy will be affected. After all, the accuracy of about 20 nanometers is too high."

Faced with this practical problem, Zhang Jingjian could only give up temporarily. After all, it is quite difficult to become fat in one go.

He continued to discuss with Xia Qiuzhen and others to strive to optimize the equipment.

The design work of nanowire textile equipment has begun to enter the substantive stage. First, a batch of parts were purchased from the market, and some special parts were customized through Snail Industry.

They first assembled a two-needle knitting machine, and obtained silicon nanowires from the laboratory. They initially tried knitting silicon nanowires and phosphorus nanowires, silicon nanowires and boron nanowires, silicon nanowires and Silicon nanowires, etc.

A lot of measured data was obtained, and the semiconductor laboratory was also taking action. Zhang Jingjian tested the woven micro-transistors while communicating and cooperating with Xia Qiuzhen.

It was discovered that these transistors could indeed implement circuit switching.

Huang Xiuyuan and Lu Xuedong are also paying attention to these studies, although large-scale mass production of equipment and chip circuit design will take time to accumulate.

However, Suiren's semiconductor research and development route has successfully bypassed many obstacles in developed countries.

At least the research and development of nanowire textile equipment is much simpler than photolithography machines and etching machines, and the nanowires themselves bypass high-purity silicon wafers and photoresist.

At the same time, there is a clear difference between the semiconductor design of the braiding method and the semiconductor design of the photolithography method. Lithography is a top-down fabrication, while braiding is a bottom-up fabrication.

In a vacuum environment, since the nanowires themselves have no impurities, the probability of defects in the woven transistor may be less than one in ten billion.

The only possible problem may occur in the chip circuit design. As long as there are no problems in the design, the defect rate of transistors produced by the weaving method will be very low, even close to zero.

Huang Xiuyuan ordered Lin Baijie to increase the search for chip design talents and increase the application for chip design patents.

Regarding patents, Suiren has always taken precautions to avoid being stuck by the West.

Semiconductor laboratory rest area.

Huang Xiuyuan looked at the progress of various projects and rubbed his temples tiredly: "Xuedong, how long do you estimate it will take to achieve mass production?"

Lu Xuedong, whose eyes were also bloodshot, replied excitedly: "If everything goes well, mass production can be initially achieved next year. I mean simple chips. As for CPUs and the like, it is estimated that it will take a while for technology to accumulate. It depends on the chip design department."

"We need chips so much." Huang Xiuyuan said helplessly.

Lu Xuedong certainly knows that although Suiren Company currently does not use chips in many places, with the rise of the Android system, Suiren Company will have to face extremely powerful enemies.

Without its own hardware system, the subsidiary's time information is like a rootless tree.
