September 20th.
8: 30 in the morning.
In the Bao Shan Industrial Zone, a group of special "guests" walked into Xing Hai Technologies' fourth research and development factory.
Most of these "guests" had grave expressions and hurried footsteps. Their slightly trembling hands indicated that their hearts were not calm.
Among these people, the one walking at the front was the chairman of Zhongxin International, Zhang Wei Jin. Behind him were the executive president, Qiu Cifeng, the general manager, Liang Meng Nan, and the director of research and development, Yang Ming. It could be said that the management of Zhongxin International had come as a group.
"President Zhang, you're here. My apologies for not greeting you at the door."
Chen Jin, who was in the factory, thought that Zhang Wei Jin and the rest would arrive after 9. He did not expect them to arrive half an hour earlier. He had to apologize.
Zhang Wei Jin waved his hand, not minding it at all. He shook Chen Zhao's hand and approached him, asking solemnly, "Mr. Chen, the 'technology' you mentioned, has your company … really succeeded in developing it?"
There was still some disbelief on his face. Could such a dreamy technology really become a reality?
"It's almost ready for use."
Chen Jin smiled and nodded. "Xing Hai spent 500 million to buy the second TC9000. Although its computing speed is still not quite fast enough, it should not have much of a problem in dealing with more complex production scenarios."
"No problem?"
Zhang Wei Jin's eyes widened. "Chip manufacturing is not as simple as' more complex. 'It's' extremely complex '! Can your 'virtual factory' really simulate such a complex production scenario? "
He still did not quite believe it.
In the industrial field, there were two things that were the crown of the crown.
One was the aircraft engine, and the other was the chip!
The chip manufacturing process was especially complex. A production line involved more than 50 industries and 20005000 processes.
Take the OEM factory for example. It needed to first purify the "sand" into silicon, then cut it into crystals, and then process the crystals. The crystal processing plant consisted of two processes. The first process was divided into several major modules – photolithography, thin film, etching, cleaning, and injection. The second process was mainly packaging – interconnection, wiring, and sealing. Photolithography was the link between manufacturing and design.
Many of the processes were carried out in independent factories. The equipment used also needed to be manufactured by specialized equipment factories. The materials used included hundreds of special gases, liquids, and target materials. All of these required a specialized chemical industry. In addition, the production of integrated circuits was carried out in ultra-clean rooms. Hence, ventilation and air purification systems were also required.
Take the most advanced 14-nanometer chip manufacturing process that Zhong Xin International had mastered as an example. Billions of transistors and control units had to be integrated on a wafer with a surface area of only 23 square centimeters. After the processing was completed, it had to be packaged and tested … The total number of processes involved exceeded 2,000.
If the scale of the transistors was smaller, the production process would increase.
Xing Hai Technologies' virtual factory technology told him that as long as he input the assembly line equipment, technical parameters, and process flow in the real world into a supercomputer in the form of data, a "virtual factory" could be built. This virtual factory could simulate the situation in the real world and simulate the manufacturing of chips.
In the "Virtual Factory", from cutting the crystal units to sealing and testing, more than 2000 procedures were completed, and a virtual "chip" was produced.
Zhang Wei Jin didn't know if this was a simulated animation or a "virtual factory" that was infinitely close to reality, but when he heard the concept, his eyes widened and he immediately realized the great significance of it.
It will bring about a revolution in the industrial field!
Such a fantastic technology is in the hands of a young company that has been established for less than two years? "
Chen Jin shook his head. "Mr. Zhang, the supercomputer can even simulate a nuclear explosion. Why can't it simulate industrial production? If you don't believe me, you can take a look at our "virtual factory." You can operate it yourself. See if it can simulate chip manufacturing. "
"Good! Seeing is believing! "
Zhang Wei Jin nodded. Then, he asked Liang Meng Nan, the general manager of Zhong Xin International, and Yang Ming, the director of research and development, to sit in front of the computer screen and operate the virtual factory.
Liang Meng Nan and Yang Ming had been exploring the field of chips for many years. They were the two generals of Zhong Xin International. Without them, Zhong Xin International's chip manufacturing technology would still be hovering around the 28-nanometer. It would be impossible to enter the 14-nanometer era so quickly.
"Hiss …"
Liang Meng Nan, who was holding the mouse and adjusting the perspective, suddenly took a deep breath.
It was too realistic.
The virtual factory on the computer screen looked almost the same as a factory in reality. The quality was so realistic that it made one gasp.
Moving the perspective into the factory, the equipment on the assembly line could be seen at a glance.
Photolithography machines, plasma etching machines, ion implanting machines, wafer slicing machines …
All kinds of equipment were replicated in a one-to-one ratio.
If one zoomed in, one could even see the inside of the photolithography machine. One could see the light beams in the photolithography machine exposing the complex circuit structure on the light-sensitive material.
"The simulation is too realistic." Zhang Wei Jin, who was standing behind the chair, took a deep breath and sighed. Excitement rose in his heart.
"Old Meng, adjust the parameters of that ion implanting machine a little. Then, observe the product yield," said the technical director, Yang Ming.
"Adjust by how much?"
"Adjust to the sixth decimal point. One in a million."
"Okay." Liang Meng Nan entered the parameter settings interface and slightly changed the parameters.
After waiting for more than two hours.
The virtual factory showed the new chip yield. It had been reduced from the initial 95% to 0.1%.
"It's exactly the same as what we've encountered in reality."
Yang Ming, who had been in charge of the production line, took a deep breath and said.
Wow …
Everyone present was astonished.
"Do a few more sets of experiments!"
Zhang Wei Jin said. In fact, he was already on the verge of yelling and screaming, but he still pressed the back of the chair hard and restrained the excitement in his heart. He wanted to confirm this shocking fact first!
Chen Jin, who was standing at the side and watching them discuss how to adjust the parameters, folded his arms and smiled.
The virtual factory technology was the first "black technology" that Xing Hai Technologies had come up with after the Wa-wah robot and the intelligent learning machine.
It was also a more intelligent and powerful "intelligent simulation program" that was developed on the basis of the "intelligent learning program." It also had a certain degree of autonomous learning ability.
Based on the combination of the "intelligent simulation program" and a supercomputer with a Flop of 80 billion, the degree of simulation achieved a deviation of less than one in ten thousand from reality.
However, as Zhong Xin International provided a large number of real parameters and data to correct the errors in various processes, the actual error rate of this virtual chip factory did not exceed one in a billion.
Moreover, the more real data provided, the smaller the error rate of the virtual factory.
The existence of this virtual chip factory would have an extremely significant impact on Zhong Xin International's chip manufacturing capabilities.
