Chapter 418 No, Let Me Do It
After a brief adjustment, life returned to normal.
At present, one of the projects that Xu You is most concerned about is the "Mathematical Scriptures" project.
However, because Huaxin International has not yet solved the problem of the preparation process of the new photonic quantum chip, the "Suanjing" project cannot continue.
"If that doesn't work, I'll go there myself."
Xu You didn't want to interfere too much in other companies' research work, but he also didn't want to be trapped in endless waiting.
After making this decision, Xu You contacted the person in charge of this project at Huaxin International through Luo Wenkun, and expressed his desire to understand the progress of the project.
After receiving Xu You's request, Huaxin International attached great importance to it and immediately arranged for someone to receive Xu You.
Escorted by several bodyguards, Xu You arrived at Huaxin International.
"You can skip all the formalities and just take me directly to the project team."
"Okay, Professor Xu, please follow me."
After arriving at the project team, Xu You and several key researchers talked about the progress of the project.
Through understanding, Xu You understood the main problems encountered in the current project.
"Professor Xu, we have tried using several silicon-based photonic chip manufacturing platforms. These methods have achieved very high yields in previous chip manufacturing, but during the trial processing of the new photonic quantum chip, problems such as low refractive index contrast of the integrated device and large device size occurred, resulting in a series of device performance degradation results."
These problems have seriously affected the quality of the chips.
Not to mention mass production, it is even impossible to produce a chip that meets the standards.
"Have you found the specific reason?" Xu You asked.
"It is under study, and it is likely related to the improvement ."
From the tone of these researchers, Xu You knew that they were not completely sure about the specific reasons.
In this case, Xu You can only take action personally.
"Please let me know the specific information."
Xu You did not blame them at all. After all, this was a task that had never been attempted in the world before.
Our chip processing technology is still in the catching-up stage, so it is very normal to encounter these difficult problems.
"Okay, Professor Xu."
They had been told before that Xu You had the right to know all information.
Regarding Xu You's problems, they must tell him everything they know.
After some detailed communication, Xu You basically understood the whole situation.
"Wait a moment!"
At this moment, Xu You suddenly remembered something.
Previously, in a conversation with Huang Sibai, Huang Sibai and Xu You talked about some chip manufacturing process technologies.
One of the technologies could solve these problems.
After returning from Huaxin International, Xu You contacted Huang Sibai through Fulun Technology.
"Mr. Huang, are you still at the head office of Fulong Technology?"
"Yes, Professor Xu, do you have something to talk to me about?"
"Well, I want to discuss a technology with you. If you have time, would it be convenient for you to come to Jijing University?"
"That's convenient. I don't have anything important to do right now. I'll be there in a moment."
"Okay, I'll wait for you at school."
Just like last time, Huang Sibai was still very active and arrived at Jijing University not long after.
"Mr. Huang, I remember you mentioned before that there is a chip manufacturing platform that can solve the problems of low refractive index contrast and large device size of integrated devices. Is that true?"
"Let me think about it... Yes, I told you about this a while ago. This problem can be solved through the intelligent chip cutting technology."
Next, Huang Sibai explained to Xu You in detail how to build the new platform and how to solve this problem.
"Combining wafer bonding technology and crystal ion slicing technology, single-crystalline lithium niobate thin films can be prepared. This method can be used to manufacture lithium niobate waveguides with high refractive index contrast to improve device performance and reduce its occupied area..."
Xu You listened carefully to Huang Sibai's explanation, and at the same time tried to simulate the corresponding scenario in his mind.
"Mr. Huang, do you have any specific images or other information?"
"Professor Xu, I came here in a hurry today and didn't bring the relevant information with me. So, after I go back, I will sort out the information and send it to you."
"Okay, then I'll trouble Mr. Huang."
Because the information currently obtained is not detailed enough, Xu You cannot accurately simulate the corresponding scenario in his brain.
According to Xu You’s preliminary analysis, the same platform may not be fully adapted if it is to be used directly to produce new photonic quantum chips.
But as long as we follow this idea and make some modifications and optimizations, there is hope that the problem can be solved completely.
After saying this, Huang Sibai did not leave immediately.
"Professor Xu, can you please tell me in what specific scenario this problem occurred? If you can let me know more details, I may be able to give you more detailed suggestions."
Because of their identities, these researchers who had just returned to China were not invited to participate in those secret projects.
Xu You hesitated for a moment, but still did not reveal any specific information to Huang Sibai.
"Mr. Huang, I won't bother you for now. If I need your further help, I'll ask you again."
Xu You tactfully rejected Huang Sibai's request. On the one hand, it was because of safety considerations. On the other hand, given the current situation, Xu You already had hope of solving this problem, so there was no need to drag Huang Sibai into it.
After all, this is important information about the next generation of quantum computers - "Suanjing", and we cannot take any risks.
Huang Sibai also understood what Xu You meant and did not ask any further questions.
"Okay, Professor Xu, feel free to contact me if you have any questions."
After returning, Huang Sibai sent the relevant information to Xu You as promised.
With this detailed information, Xu You can simulate the manufacturing process of integrated devices more accurately.
…
In the darkness.
A man in black, holding an unknown device, was whispering something.
"They seem to be researching new photonic quantum chips, which require a very high manufacturing process and require EUV lithography equipment."
"Is it the chip for the next generation of Fulong mobile phones?"
"It's not clear yet, but what is certain is that once they successfully build this chip, its performance will definitely not be underestimated."
"According to our ban, they cannot use EUV lithography machines to mass-produce their chips. It can't be..."
