Black technology: I have a refitting factory

"But what?"

Kong Yang asked quickly.

Hearing the first half of Liu Shiwei's words, his heart froze.

If the Institute of Microelectronics has no solution, other places will have no solution even more.

"We can't help it, but someone may have a solution, haha! Just wait for a day, he will be here tomorrow, ask him."

Liu Shiwei said.

"Is there someone? Can I do it alone?"

Kong Yang murmured in his heart, but he didn't ask any more questions. Now that Liu Shiwei has said it, it will not be empty talk.

I just don’t know who this person is?

After chatting with Kong Yang about some other things, Liu Shiwei picked up the information and prepared to read it again after sending Kong Yang away.

At this time.

Tuk-tuk-tuk!

There was a knock on the door.

"Please come in!"

Liu Shiwei spoke up.

"Academician Liu, the people from Zhongwei are here. Waiting in the second conference room."

Chen Yingxin said.

"Oh, okay, I'll be right away."

Liu Shiwei responded and then put the information away. In today's situation, the information cannot be seen.

Second conference room.

Zhao Cong put his hands on the table and turned his cell phone back and forth.

After entering the institute, he made some inquiries. 3D stacked crystal technology is actually already in the experimental stage of mass production.

This made him excited and nervous at the same time.

What’s exciting is that this technology is here far ahead of their expectations.

What's important is that the core of this technology is said to be not controlled by the institute, but by someone else.

In addition, it is unknown how much performance this technology can improve if it is actually used on existing chips, and what model of machine it will match.

All of this requires in-depth communication with Liu Shiwei to draw conclusions.

Although he had made preparations before coming and had nothing to gain, when he actually heard that there was hope, he still hoped for the best outcome.

The best thing is that it can replace most of the chips.

Only in this way can we have enough confidence to face this doubt and turmoil!

despair! despair! despair!

Footsteps sounded from outside the door. Zhao Cong stopped turning his cell phone and looked at the door.

After a while, Liu Shiwei's figure appeared at the door.

Zhao Cong hurriedly put away his phone and went to greet him.

After a while of pleasantries, Zhao Cong went straight to the point and explained his purpose: "...The situation is like this. Because of the Dragon Soul EDA incident, Synopsys bought a lot of trolls to spread rumors that some of us would use self-developed chips, and also questioned whether Dragon Soul EDA was Copy them.

In addition, some people at home and abroad are adding fuel to the flames, and now we are at the forefront of the storm. As for their rumor that we use self-developed chips, our boss did not want to deny it and weakened his momentum.

But for self-research, you should be very clear that the highest process is 40nm, which is not enough for low-end machines, not to mention those mid-to-high-end machines.

It is impossible to improve the manufacturing process, so we can only use other means to bypass the manufacturing process. We have discussed that 3D stacked crystal technology is one direction. This is what I came here for.

When he said this, he stopped, thought about his words, and then continued, "I entered the research institute and heard that this technology has made great progress. Academician Liu, please take a look here so that you can help me evaluate the feasibility." .

And if 3D stacked crystal technology is used with a 40nm process, it can be used to replace our kind of chip products. "

"Of course you can."

Liu Shiwei nodded. He had seen this from the news.

Zhongwei would not come to visit him, but would take the initiative to ask about the situation when he was free.

"But I don't know much about your requirements. Have you brought us the current chip information and related requirements?

You have to see it to make an assessment. "

Liu Shiwei said again.

"Bring it, bring it!"

Zhao Cong nodded quickly, and then motioned to the staff who were following him to give the information to Liu Shiwei.

Some of these are business secrets, but at this moment, I can't control so much.

Liu Shiwei took the information, then took out his glasses from his pocket and looked through them slowly.

The entire conference room fell silent, except for the sound of Liu Shiwei flipping through information.

Liu Shiwei read it very carefully, and it took him three hours to finish it.

Putting down the information, Liu Shiwei thought for a while and said, "I still have some questions here..."

"The corresponding technicians are all here with me. If you have any questions, just ask them. We will definitely answer them if we know them."

Zhao Cong said hurriedly.

"Here, this parameter..."

Liu Shiwei opened the information, pointed to a certain place and started asking Zhao Cong and others.

Another two hours passed with questions and answers.

The conference room became quiet again. Liu Shiwei tapped his fingers on the table and fell into deep thought. Zhao Cong and others did not dare to make a sound. They looked at Liu Shiwei anxiously and waited patiently.

quite a while.

"You guys, your 3D stacked crystal technology alone can reach the level of mid-range chips at best."

Liu Shiwei suddenly said, "Anything higher, such as several of your best-selling mid-range chips, all require at least a 14nm process. A 14nm process requires at least a 28nm process manufacturing process, coupled with 3D stacked crystal technology. , to meet the requirements.

The 28nm process is not so easy to break through. This thing may take half a year, or it may take three or four years.”

"That's it. The average level of mid-range chips is acceptable."

Zhao Cong replied, saying that, but he was still a little lost in the words.

Before coming here, I thought there was no hope.

After hearing about the realization of 3D stacked crystal technology, he came up with the idea that perhaps high-end chips can also be replaced. This kind of announcement is the most confident.

It only replaces mid-to-low-end products. Although it can be considered a slap in the face, it is still a disguised compromise.

Seeing Zhao Cong's expression, Liu Shiwei seemed to remember something and said: "To complete most of the replacements, there is another way to go. It is the combination of 3D stacked crystal technology and in-memory computing. In this way , maybe it can be compared to the level of 7nm with the 40nm process..."

When he said this, he paused and said with some uncertainty, "But... this thing, I just think it is possible in theory, but I am not sure whether it can be done in practice.

In addition, when this in-memory computing can be mass-produced is also a relatively uncertain time. "

After a pause, he added, "Let's wait until tomorrow. The expert will come tomorrow. If you ask him, it will be clear. Speaking of which, you should still be familiar with this expert."

Zhao Cong suddenly became energetic. He originally thought there was no hope, but it turned out that another village had a bright future. If he could complete most of the replacements, the harvest would be huge this time.

That will be the second step in the rise of China's chips! !

After getting excited, he recalled Liu Shiwei's last words and asked curiously: "Expert or acquaintance...who is it?"

The person who could be called an expert by Liu Shiwei was not an ordinary person. He went through it in his mind, but he didn't have a clue.

"Haha, we'll find out tomorrow. Just rest today!"

Liu Shiwei made a haha.

He had a sudden whim, and he wanted Zhao Cong to experience what Su Qi was shocked by that day.

"Who is it?"

Seeing that Liu Shiwei refused to talk, Zhao Cong became even more curious. He had gone through the experts over forty years old in his mind, but still had no clue. Those people were indeed experts in the field, but it felt difficult for Liu Shiwei to call them experts.
