Technological power starts with upgrading lenses

Chapter 70 The autonomy rate is 95%! 【Please order first】

Due to the special circumstances, the expert team went faster this time than the last time they went to Silicon Information Technology.

In the afternoon of the next day, they rushed from all directions to Steel City to gather.

But the leaders of Steel City who were responsible for the reception were extremely busy.

But this kind of busyness makes them eager to come back a few more times...

Except that Wu Lihong did not come to avoid suspicion, the expert team changed its leader, and the other members basically remained unchanged. So after arriving in Steel City, they just had a brief meeting and went directly to Dahan Silicon Industry.

At this time, Kang Chi had already received the news, and he and his employees were eagerly waiting. When they saw the expert team coming, they immediately greeted them.

"Academician Zhang, hello, hello." Seeing the old man in the lead, Kang Chi did not dare to neglect at all. He stretched out his hand and said, "Thank you for your hard work after a long journey."

The old man who, together with Wu Lihong, was also known as the Beidou of China's chip industry, just nodded, shook Kang Chi's hand gently, and then looked Kang Chi up and down before saying, "Not bad, I didn't embarrass Old Wu. "

"Well……"

Is this a compliment to him?

But listening to his tone, why does he seem a little unhappy?

Kang Chi was a little confused and could only respond with a smile.

"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 Steel City leaders all walked into the test workshop.

The review process is similar to that of Silicon Information Technology. The expert team first conducts a technical review of the design drawings of the equipment.

At this stage, the company does not need to provide specific information, but only needs to provide the overall design drawing so that they can roughly understand the design ideas and principles, and confirm that there are no major technical flaws.

Then there is the inspection of equipment parts.

This process is relatively long and requires a detailed review of the sources of thousands of parts 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 meet 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 an autonomy rate of 95%.

But this data is for the car product 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 you push forward further, the 20% of independently developed production line equipment and the parts and components in the equipment have almost all just crossed the 40% standard line.

The semiconductor industry is actually similar. At present, the chip production equipment that can be manufactured in China, regardless of its performance, just looks at the proportion of domestic parts, most of them are on the 40% passing line, and only physical vapor deposition and oxidation equipment and other specific areas of strength, can exceed 50%.

As for key equipment such as photolithography machines, which have an independent rate of less than 10%, they are not even considered domestically produced.

Therefore, when Zhang Dayuan saw that the parts autonomy rate of Dahan Silicon's single crystal furnace was actually 95%, his eyes widened on the spot and he asked in disbelief: "Are you sure this autonomy?" Did you fill in the rate correctly?"

"Uh... that should be right."

Kang Chi hesitated for a moment, then explained with a guilty conscience: "I don't know what your specific review standards are. About 5% of our parts processing equipment is indeed imported..."

"If the parts processed using imported equipment are not considered independent, then our filling may be a bit high and have to be lowered to about 90%. This is mainly because we are in a hurry and do not have the energy and funds to specifically manufacture these 10%. Parts processing equipment..."

"..."

So what you mean is, if I give you more time and funds, you can achieve 100% autonomy?

Zhang Dayuan opened his mouth, not knowing what to say.

Praise him, I feel like he pretended to be good.

Don't praise him. Looking at his cautious look, he seems to be feeling guilty for not handing in a perfect answer sheet...

This is very uncomfortable.

"Ahem, as long as your data is not falsified, it does not matter whether it is 95% or 90%."

Zhang Dayuan could only deal with it this way, and then organized experts to conduct random sampling surveys on the production records of independent parts and components.

In order to facilitate their review, Kang Chi also did enough homework in advance.

When he was looking for OEMs, he asked Dahan Silicon's engineers to record the situation of each component OEM in detail, even down to the model of processing equipment and processing methods.

As for the key components that I have conquered, let alone that.

The equipment is placed in other workshops, and there are several large boxes of trial and error plans, all eagerly waiting for the expert team to take a look.

The independent rate review lasted until eight o'clock in the evening, and the expert team was surprised to find no flaws.

Zhang Dayuan, who did not believe in evil, decided to let everyone rest for a while and continue the investigation the next day.

But the next day, the sampling rate almost reached 20%, and the results were still the same.

None of the parts that were extracted had questionable origins.

Now Zhang Dayuan finally believes that 95% of the data has no moisture at all!

Faced with this result, even Zhang Dayuan couldn't help but admire: "What you did...isn't it so beautiful?!"

"I saw that there are many parts and components that, if we follow the previous manufacturing ideas, can only be processed abroad, but you are able to find a new way and use completely different processing methods and equipment to replace them in parallel. It is really rare! Just these, I don’t know how many academic papers can be published..."

"That's right!" At this point, Zhang Dayuan couldn't help but change the subject, "Old Wu hasn't graduated you yet?"

"Old Wu?"

Being praised so highly by academicians from both academies, Kang Chi was a little confused and almost didn't even realize who Old Wu was.

"Wu Lihong!"

"Oh, tell me, Teacher Wu, I have been quite busy during this period, so I just published a paper on annealing embrittlement of silicon wafers. How could 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 any more questions, but continued the topic: "He is a grinding person in doing things, just throw these information to him and let him I’ll just graduate you.”

"Well, let me try later?"

"Yes." Zhang Dayuan nodded like a coward.

"By the way...Old Wu is engaged in photolithography and etching research. He just stares at the broken glue all day long. How boring is it for you to follow him? How about you come to the University of Science and Technology and we can do equipment research and development together? My scientific research funds are comparable to his. That’s a lot!”

"..."

Looking at Academician Zhang who met Tu Qiong, Kang Chi couldn't help but feel a little dizzy.

He could tell that Zhang Dayuan and Wu Lihong should have a good personal relationship, but they competed with each other professionally and academically, with no one losing.

No wonder his attitude was a little strange when we first met...

"Uh... I will think about it when Teacher Wu lets me graduate, but I still prefer to think about it alone..."

"We can do what Lao Wu did, let you be a part-time professor, and occasionally exchange experiences."

"..."

Kang Chi didn't answer, just smiled in apology.

Zhang Dagyuan didn't force the situation, he just snorted lightly and started the next review process.
