Chapter 70 95% autonomy! [First order requested]
Due to the special circumstances, the expert group was faster this time than the last time they went to Silicon Technology. On the afternoon of the second day, they rushed directly from all directions to Gangcheng before gathering, which made the leaders of Gangcheng who were responsible for the reception very busy.
However, they would like to come more often for such a busy schedule…
Except for Wu Lihong who did not come to avoid suspicion, the expert group changed its leader, and the other members basically did not change, so after arriving in Gangcheng, they just met briefly and then went directly to Dahan Silicon Industry.
At this time, Kang Chi had already received the news, and he was looking forward to it with his employees. When he saw the expert group coming, he immediately greeted them.
“Academician Zhang, hello, hello,” seeing the old man leading the way, Kang Chi did not dare to neglect it at all, and stretched out his hand and said, “You have worked hard on the journey.”
The old man, who is known as the leader of China’s chip industry together with Wu Lihong, just nodded, shook hands with Kang Chi gently, and then looked Kang Chi up and down before saying, “Not bad, you didn’t embarrass Old Wu.”
”Uh…”
Is this a compliment to him? But from his tone, why does he seem a little unhappy?
Kang Chi was a little confused and could only force out a smile as a response.
”Let’s go, take us to see the single crystal furnace you built.”
”Well, okay, everyone, please come in.”
Under the leadership of Kang Chi, the expert group and the leaders of Gangcheng walked into the test workshop together.
The review process is similar to that of Silicon Technology. The expert group first conducts a technical review of the design drawings of the equipment.
In this link, the company does not need to provide specific information, as long as the overall design drawings are provided, so that they can roughly know the design ideas and principles, and confirm that there are no major technical loopholes, it will be considered passed.
Then there is the inspection of equipment parts.
This process is relatively long, and the sources of thousands of parts must be carefully reviewed to ensure that domestic parts account for more than 40%.
At first glance, this requirement seems quite low.
But in fact, it is not easy for domestic semiconductor companies to reach this standard.
Take the familiar car as an example. As long as the domestic production rate of domestic auto parts exceeds 40%, it is considered an independent brand.
The best in this regard is BYD, which can reach about 75%. If it is a pure electric vehicle, it can even achieve a 95% autonomy rate.
However, this data is for the car itself. If you continue to push forward, you will be surprised to find that the localization rate of domestic automobile production lines is actually only about 20%!
If we go back further, the 20% of the self-developed production line equipment, the self-reliance rate of the parts in it, almost all just stepped over the standard line of 40%.
The semiconductor industry is actually similar. At present, the chip production equipment that can be made by China itself, regardless of its performance, just looking at the proportion of domestic parts, most of them are also stepping on the passing line of 40%. Only specific strong areas such as physical vapor deposition and oxidation equipment can exceed 50%.
As for key equipment such as lithography machines, which have a self-reliance rate of less than 10%, they are not even considered domestic.
Therefore, when Zhang Dayuan saw that the self-sufficiency rate of Dahan Silicon Industry’s single crystal furnace parts was filled in at 95%, his eyes widened on the spot and asked in disbelief: “Are you sure the self-sufficiency rate is correct?”
”Uh… it should be correct.”
Kang Chi hesitated for a moment, and explained with a guilty conscience: “I don’t know what your specific audit standards are. We have about 5% of parts processing equipment, which are indeed imported…”
”If the parts processed with imported equipment are not considered self-sufficient, then we may have filled in a little too high and have to reduce it to about 90%, mainly because we are in a hurry and don’t have the energy and funds to specially build this 10% of parts processing equipment…”
”…”
So from what you mean, if you are given more time and funds, you can achieve 100% self-sufficiency?
Zhang Dayuan opened his mouth, not knowing what to say.
If I praise him, I feel like he is showing off. If I don’t praise him, he looks so cautious, as if he still feels guilty for not handing in a perfect answer sheet…
This is very uncomfortable.”Ahem, as long as your data is not false, whether it is 95% or 90%, it is qualified.”
Zhang Dayuan could only deal with it like this, and then organized experts to conduct a random sampling survey on the production records of independent parts.
In order to facilitate their review, Kang Chi also did enough homework in advance.
When he was looking for a foundry, he asked the engineers of Dahan Silicon Industry to record the situation of each parts foundry in detail, even down to the model and processing method of the processing equipment.
As for the key parts that he conquered, let alone, the equipment was placed in other workshops, and there were several large boxes of trial and error solutions, all waiting for the expert group to see.
The review of the independent rate lasted until eight o’clock in the evening, and the expert group did not find any loopholes. Zhang Dayuan, who did not believe in evil, decided to let everyone rest first and continue the investigation the next day.
But the next day, the sampling rate was almost 20%, and the result was still the same.
None of the parts that were picked had problems with their sources.
Now Zhang Dayuan finally believed that the 95% data was not exaggerated!
Faced with this achievement, even Zhang Dayuan couldn’t help but admire: “You guys did… too well, right?!”
”I saw that there are many parts that, if we follow the previous manufacturing ideas, can only be processed abroad, but you can find a different way and use completely different processing methods and equipment to replace them in parallel. It’s really rare! Just these alone, I don’t know how many academic papers can be written…”
”By the way!” At this point, Zhang Dayuan couldn’t help but change the subject, “Old Wu hasn’t graduated for you yet?”
”Old Wu?”
Being praised by academicians of the two academies, Kang Chi was a little confused and almost didn’t even react to who Old Wu was.
“Wu Lihong!”
”Oh, you mean Professor Wu? I’ve been busy lately, so I just published a paper on silicon wafer annealing embrittlement. How can I graduate so quickly?”
Silicon wafer annealing embrittlement? Zhang Dayuan vaguely smelled something, but there were many people at the scene, so he didn’t ask much, but continued the previous topic: “He is a person who is always procrastinating. You can just throw these materials to him and let him graduate for you.”
”Well, I’ll try it later?”
”Okay.” Zhang Dayuan nodded with a teachable look.
”By the way… Old Wu is doing photolithography and etching research. He just stares at that broken glue all day long. How boring is it for you to follow him? Why don’t you come to the University of Science and Technology and work on equipment research and development together? I have much more research funds than him!”
”…”
Looking at Academician Zhang, who was showing his true colors, Kang Chi couldn’t help but feel a little overwhelmed.
He could tell that Zhang Dayuan and Wu Lihong had a good personal relationship, but they were competing with each other in professional and academic fields, and neither of them would lose to the other.
No wonder his attitude was a little strange when they first met…
”Uh… I’ll consider it when Teacher Wu lets me graduate, but I still prefer to think about it alone…”
”We can let you be a professor in idle time like Old Wu did, and occasionally exchange experiences.”
”…”
Kang Chi didn’t answer, but just smiled.
Zhang Dayuan didn’t force it, but just snorted softly, and then started the next review stage.
