Due to the special situation, the speed of the expert group this time is faster than the last time I went to Silicon Technology Technology.

In the afternoon of the next day, they rushed directly from all directions to the steel city before they assembled.

But the leaders of the steel city who were in charge of the reception were busy.

But with this kind of busyness, they wish to come a few more times......

Except for Wu Lihong who did not come to avoid suspicion, the expert group changed their handsomeness, and the other members basically did not change, so after arriving in Gangcheng, they just briefly bumped into each other, and then came directly to Dahan Silicon Industry.

At this time, Kangchi had already received the news, and the employees were waiting for it, and immediately greeted the expert group as soon as they saw it.

"Academician Zhang, hello, hello," seeing the old man in the lead, Kang Chi did not dare to slack off at all, stretched out his hand and said, "The boat is tired, you have worked hard." ”

The old man, who was also known as Huaguo Chip Taishan Beidou with Wu Lihong, just nodded, shook hands with Kang Chi gently, and then looked Kang Chi up and down before he spoke: "Yes, I didn't embarrass Lao Wu." ”

"Uh......"

Is this a compliment to him?

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

Kangchi was a little confused, so he could only squeeze out a smile in response.

"Let's go, take us to see the single crystal furnace you built."

"Well, okay, folks, please."

Under the leadership of Kangchi, the expert group and the leaders of the steel city walked into the test workshop together.

The audit process is similar to that of Silicon Trust, and the expert group first conducts a technical review of the design drawings of the equipment.

In this link, the enterprise can not come up with specific information, as long as the overall design drawing is taken out, so that they can roughly know the design ideas and principles, and confirm that there are no major mistakes at the technical level.

And then it's time to check the parts of the equipment.

This process is relatively long, and it is necessary to conduct a detailed audit of the source of thousands of parts to ensure that the proportion of domestic parts is more than 40%.

At first glance, this seems to be a pretty low request.

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%, and if it is a pure electric vehicle, it can even achieve an autonomy rate of 95%.

But 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 you push it further, the 20% self-developed production line equipment, the autonomy rate of parts and components, almost all of them have just stepped on the standard line of 40%.

In fact, the semiconductor industry is similar, at present, the chip production equipment that can be made by itself in China, regardless of its performance, just looking at the proportion of domestic parts, most of them are stepping on the passing line of 40%, and only specific areas such as physical vapor deposition and oxidation equipment can exceed 50%.

As for key equipment such as lithography machines, with an autonomy rate of less than 10%, they are not even domestic.

Therefore, when Zhang Dayuan saw that the autonomy rate of the parts of Dahan Silicon Industry's monocrystalline furnace was 95%, his eyes widened on the spot, and he asked in disbelief: "Are you sure that this autonomy rate is not wrong?" ”

"Uh...... Probably yes. ”

Kang Chi hesitated for a moment, and explained with some humility: "I don't know what your specific audit standards are, we have about 5% of the parts processing equipment, which is indeed an imported ...... to buy."

"If you use imported equipment, the parts processed are not autonomous, then we may fill a little high, and we have to reduce it to about 90%, mainly because we are in a hurry, and we don't have the energy and funds to build this 10% of the parts processing equipment......"

“……”

So what you mean by this is that if you are given a little more time and money, you can achieve 100% autonomy?

Zhang Dayuan opened his mouth, a little unsure of what to say.

Praise him, and I feel like he's pretending to be,

Don't praise him, looking at his cautious appearance, it seems that he is still guilty of not handing in the full score of the answer sheet......

It's hard.

"Ahem, as long as your data is not falsified, it doesn't matter if it's 95% or 90% qualified."

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

In order to facilitate their review, Kangchi also did his homework in advance.

When he was looking for an OEM, he asked the engineers of Dahan Silicon to record the situation of each component foundry in detail, even down to the model and processing method of the processing equipment.

As for the key components that you have conquered yourself, not to mention,

The equipment is placed in other workshops, and there are several large boxes of trial-and-error plans, all waiting for the expert group to see.

The self-determination rate review lasted until eight o'clock in the evening, and the expert group was stunned to find no mistakes.

Zhang Dayuan, who does not believe in evil, decided to let everyone rest first and check the next day.

But the next day, the sampling rate was almost 20%, and the result was still the same.

None of the parts were drawn, and the source was questionable.

Now Zhang Dayuan finally believes that 95% of the data is without a little moisture!

Faced with this achievement, even Zhang Dayuan couldn't help but praise: "What are you doing...... It's beautiful, isn't it?! ”

"I see that there are a lot of parts, if you follow the previous manufacturing ideas, you can only find foreign processing, but you can find another way, with completely different processing methods and equipment to replace in parallel, it is really rare! I don't know how many academic papers can be published in this alone......"

"That's right!" Speaking of this, Zhang Dayuan couldn't help but change his words, "Lao Wu hasn't graduated from you yet?" ”

"Old Wu?"

was so praised by the academicians of the Chinese Academy of Sciences and the Chinese Academy of Sciences, Kang Chi was a little unable to find the north, and he almost didn't even react to who Lao Wu was.

"Wu Lihong!"

"Oh, you said Mr. Wu, I was busy during this time, so I sent a paper on the annealing and embrittlement of silicon wafers, how could I graduate so quickly."

Wafer annealing and embrittlement?

Zhang Dayuan vaguely smelled something, but there were many people at the scene, so he didn't ask much, but continued the topic just now: "He is a person who does things like grinding and chirping, you just throw these materials to him and let him graduate for you." ”

"Well, I'll try it later?"

"Yes." Zhang Dayuan nodded with a teachable look.

"Anyway...... Lao Wu is engaged in photolithography and etching research, and he stares at the broken glue all day long, how boring are you following him? Why don't you come to the University of Science and Technology, and we will engage in equipment research and development together? I have a lot more research funding than he does! ”

“……”

Looking at Academician Zhang, who was poor in the picture, Kang Chi couldn't help but feel a little big.

He can hear it, this Zhang Dayuan and Wu Lihong should have a good personal relationship, but they compete with each other professionally and academically, and no one loses anyone.

It's no wonder that when we first met, his attitude was a little strange......

"Uh...... When Mr. Wu lets me graduate, I will consider it, but I still prefer to ponder by myself......"

"We can be like Lao Wu, let you hang up as an idle professor and occasionally exchange experiences."

“……”

Kangchi didn't answer, just laughed.

Seeing this, Zhang Dayuan didn't force it, just snorted softly and started the next review link.

Thank you for the first order support, all the readers, fairy boss~
