Big Country Intelligent Manufacturing

"Okay, let's go to the silicon wafer slicing workshop and wait." Xu Zhenming smiled in a good mood and gladly accepted the invitation of Wanninggu and others.

Not long after, everyone moved to the end of the silicon wafer production line.

This is the silicon wafer rod rounding, polishing and wafer slicing workshop.In order to prevent the monocrystalline silicon particles from damaging the human body, the production line in the workshop has been changed to a fully automatic method, almost without human operation.

Not only that, the entire workshop is sealed, and there is a dust removal system to recover the monocrystalline silicon microparticles in the air.Once the monocrystalline silicon microparticles are inhaled into the lungs, it will produce an occupational disease "silicosis".

Xu Zhenming didn't want this kind of thing to happen to Yiming Group. At the beginning of the production line construction, he discussed with Wanninggu to solve the problems of environmental protection and workers' working environment.Either don't do it, or there is basically no hidden danger.

Therefore, Wanninggu received the two 8-inch silicon wafer production lines from Korea, and they all made major surgical transformations, cooling, reloading, and entering the grinding machine for clamping, rounding, polishing and other processes. All let the technicians of the CNC machine tool factory of Yiming Group do the transformation to create today's fully automatic production line.

As a result, the construction cost of these two 8-inch silicon wafer production lines will increase by about 40%.But Xu Zhenming thought it was worth it, and looked at the glass window production line with interest.

"Woo..." At this moment, a gray-black round rod with a diameter of more than 20 centimeters was dumped out of the sealed box workshop by two yellow robots.The red warning light outside the workshop is constantly flashing, and the alarm is constantly ringing.

Seeing this scene, Wan Ninggu grinned and explained to Xu Zhenming: “Xu Dong, this silicon wafer rod has been cooled, and now it needs to be rounded on a grinder until the outer diameter is polished to the specified size of 8 inches.”

"Hmm..." Xu Zhenming replied, the gray-black single crystal silicon round rod as far as he could look.

The color of monocrystalline silicon is gray-black, and once polished, it will give off a metallic luster.

Xu Zhenming also knew this knowledge.

At this time, the single crystal silicon round rods on the two yellow robots had pointed cones at both ends.In the center of the round bar, you can see obvious traces of circles.These traces are formed when single crystal silicon rotates and crystallize, like small round hoops.Of course, this is the state of semi-finished products.

The monocrystalline silicon round rods to be sold are all rounded and polished, and the surface is smooth and shiny, with sparkling metallic luster.

While Xu Zhenming and others were talking, the two yellow manipulators began to move and came to the side of the CNC grinder, put the single crystal silicon round rod into the CNC grinder, and clamped it.

"Huh..." Seeing this scene, Wan Ninggu finally let out a breath.

He saw Xu Zhenming, Huang Li and Wu Tianling looking at him with a little surprise in their eyes, and couldn't help but smile, "Single crystal silicon is very fragile, and it will shatter if one is not careful. I am afraid that the palletizing robot's movements are not flexible enough and will be damaged. The first sample."

"That would not be beautiful, Mr. Wan has to adjust this production line immediately!"

"Yes!"

Huang Li and Wu Tianling have deep experience and understand Wanninggu's mood.

The two of them, like Wanninggu, spend the days in this compound, specializing in debugging the production line of the optical fiber preform.

At this moment, the optical fiber preform should also be offline.

"Xu Dong, it will take two or three hours to see the finished silicon wafers here. Let's take a look at the offline situation of the optical fiber preform?" Therefore, the two of them strongly invited Xu Zhenming to the optical fiber preform. Visit the end of the production line.

Of course Xu Zhenming had no objection. He greeted Wang Ninggu and went straight to the workshop of optical fiber preform.

When they came to the end of the optical fiber preform, they happened to encounter that the optical fiber preform had been cooled and was moved out of the closed cold zone workshop.

Like the monocrystalline silicon production line, two yellow manipulators are used here to clamp and transport optical fiber preforms.

At this moment, a colorless, transparent, round glass rod of twenty centimeters thick was sandwiched on the yellow manipulator.This glass rod is an optical fiber preform.

The composition of the optical fiber preform is pure silica, which is colorless and transparent. It is also very brittle after cooling and is easy to break.

According to reason, this optical fiber preform can be used as a raw material without polishing and rounding.Anyway, when producing optical fibers, the optical fiber preform is heated and melted in a heating furnace, and then drawn into optical fiber filaments.

However, Yiming Group does not produce optical fiber itself, and the by-product optical fiber preforms produced are sold as commodities.Therefore, this newly released optical fiber preform has to be rounded, polished, and packaged before it can be sold as a commodity.

When the manipulator of the yellow palletizing machine clamped the optical fiber preform blank, Huang Li and Wu Tianling, like Wan Ninggu, held their breath and stared into the glass window unblinkingly.

"Huh..." Seeing the two yellow manipulators finished their hands, the CNC grinder automatically closed the glass door, and they both let out a long sigh.

Seeing this scene, Xu Zhenming couldn't help laughing, "Don't be nervous. It's during the trial production period. It doesn't matter if something goes wrong." Although he said that, he still hopes that today's trial production will succeed.

This step is of great significance, and it is also a very big progress for the semiconductor industry.If you compare it, this production process can be as good as the "Hou's Soda Method", and it is the first important invention of the Chinese in the semiconductor industry.

Therefore, Xu Zhenming has not left the compound and waited in Wanninggu's office.

Around two o'clock in the afternoon, Wanninggu, Huang Li, and Wu Tianling all walked into Wanninggu's office with a smile.

They both held a glass bottle in their hands, and there was a small disc in the bottle.The three small wafers are samples of three products, such as 8-inch silicon wafers, optical fiber preform slices, and monocrystalline silicon photovoltaic panel slices.

"How is the situation? When will the sample test results come out?" Seeing this scene, Xu Zhenming asked Wanninggu impatiently.

At this point in the trial production, how could he not be anxious when it was time to give results?

For this silicon wafer manufacturing base, Yiming Group has invested a total of about 3.2 billion yuan. How many bosses are willing to play this way?

"I slice the optical fiber preform here, and it only takes an hour to get a test report."

"Report Xu Dong, the slice inspection report of monocrystalline silicon photovoltaic panels, at least two hours."

"The inspection of 8-inch wafers takes longer. I am afraid it will take four or five hours to produce results."

Although Xu Zhenming was so anxious, Wan Ninggu, Huang Li and Wu Tianling still told the truth and worked according to normal procedures.

Having said this, the three of them hurriedly left and began to arrange tasks.

"Jingle Bell……"

An hour later, Xu Zhenming's cell phone rang suddenly, awakening him from work."How's the situation, Dr. Huang?" He glanced at the caller ID and pressed the call button impatiently.

"Successful Xu Dong. We succeeded! Hahahaha..." Huang Li's ecstatic laughter came from the phone.

Xu Zhenming couldn't help but clenched a fist with excitement, "It's great! I want to congratulate you Dr. Huang, you have created a new subject. Once the paper of this kind of technology is published, it will definitely win many international awards." He was excited and incoherent. , Almost forgot the agreement he had made with Huang Li, Wan Ninggu and others.

According to Xu Zhenming's vision, Yiming Group will temporarily keep this joint monocrystalline silicon process secret, and wait two years before publishing it in the form of a paper.The main purpose of this is to allow Yiming Group to earn back the cost of the subject experiment in this way.

More than two hours later, Wan Ninggu hurriedly walked into the office holding a document."Report Xu Dong, the slices of monocrystalline silicon photovoltaic cells have passed the inspection and the quality has reached European standards." He smiled and passed the report in his hand to Xu Zhenming.

In other words, the quality of the two by-products of this 8-inch monocrystalline silicon round rod production line is qualified.In fact, the trial production has achieved this step, and it can actually be considered a success.If the monocrystalline silicon liquid leading to the production line is divided into two branches, Yiming Group will not lose money.

But the product Xu Zhenming wants most is 8-inch silicon wafers.

If this product cannot be made domestically, the neck will always be caught by the islanders.Therefore, he waited patiently, having dinner and work in Wanning Guogu's office, and waiting for the result with Wanninggu.

At around 6:30 in the evening, Zhang Nyjin, who had received the news, also came to Wanninggu's office to join in the fun.His team members also participated in the performance test of the silicon wafers, so they were naturally more concerned.

Besides, the inventory of silicon wafers purchased by Yiming Group is already low.If this trial production fails to succeed, he will also make suggestions based on the test report to help Wanninggu.

"Old Zhang, if you don't go home to accompany your wife after get off work, why did you come to me?" Wanning Gu was confused and deliberately teased Zhang Nyjin.

Hearing this, Zhang Neojin opened his mouth and laughed, "Lao Wan, I have arranged people to prepare. Once your side succeeds, they will change the website made by Mingxin. I have already thought about the content— —'A major breakthrough in the manufacturing of Huaguo Semiconductor, we can now manufacture 8-inch silicon wafers', what do you think?"

"I think it will work!" Xu Zhenming, leaning on the sofa, answered this question instead of Wanninggu."Once we make this advertisement, the islanders' silicon wafers will immediately plunge, and the price will drop by about 40%." He said his point of view with a smile.

"I think at least 45%. The islanders want to suppress us and make us regret launching a silicon wafer factory."

"About 50%, or more. They may even sell silicon wafers at a loss."

Zhang Neojin, Wanninggu and Xu Zhenming had different opinions. They believed that the islanders would either not do it or they would never do it.

It is said that the two of them grew up in Wanwan, and they might know the islanders better.Xu Zhenming didn't hold back with them.The tendency of islanders to cut prices to suppress Yiming Group can be thought of without thinking about it.

For example, Korea’s three electronics groups were successful in the 1980s and were able to manufacture chips and silicon wafers.

In the past few years, the price of global electronic chips plummeted, and the three companies of Sanxin Electronics, Xiang Dai's disciple and LG Electronics almost went bankrupt.If it were not for the support of the Goryeo government, all three of them would cut off chip manufacturing projects.

For example, in another time and space, SMIC successfully cooperated with Xiangjiang Electronics, and spent more than 20 million dollars to rebuild the production line.At this time, the world's electronic chip foundry costs plummeted again, and domestic companies all went to Wanwan and the United States to tape out films.

SMIC is very embarrassed, there is a production line but no one comes to tape out.If no one is taped out, your manufacturing industry workers will not be able to get Foundry production experience, let alone develop new processes.Over time, SMIC was left behind and could not catch up with others.

With these examples for comparison, Mr. Xu can't think of the next move of the islanders?But fortunately, Yiming Group does not need to use OEMs to maintain it. It is cool to be able to design chips by itself.

"Bang bang bang..." At this moment, there were waves of knocks on the door.

Seeing this scene, Zhang Nyjin looked at Wanninggu with wide eyes, "Is the inspection data of the silicon wafer coming?"

"Please come in!" Wan Ninggu nodded and looked at the door of the office.

as predicted.

A young male engineer, holding a pile of reports, pushed open the wooden door of the office."Report to Mr. Wan, good news! Ok...Xu Dong is here too! Hehehe..." He reported the situation happily.When he found Xu Zhenming in the office, he couldn't help but blush and smile.

Hearing this vague report, Xu Zhenming smiled with joy, "Okay. The Chinese people finally catch up with the world in the production of silicon wafers." Thinking of this, he applauded excitedly. Come.

"Hurry up and show me the report!" Wan Ninggu had already got up at this time and took a sharp step towards the technician.

Because of his carelessness, the head bone of his calf hit the armrest of the wooden sofa.This one must be very heavy, otherwise Wan Ninggu would not clenched his teeth, grinned, his face was particularly hideous.

Not only that, Wanninggu stood there with his left leg standing on the ground and his right leg slightly bent and suspended in the air."Okay, okay! The purity reaches 12N, and the interference and flatness are all qualified. Hahahahaha..." Although it hurts a bit, he still laughed, his eyes full of joy.

Why is Wanning Gu upset after a successful trial production?

Besides, Huaguo's silicon wafer production companies have not yet achieved such purity.

In another time and space, the 11N-level monocrystalline silicon rods can only be reached by the Chinese in the past few years.The gap is not generally large.

Therefore, it is not enough to have foreign import and export production lines, you have to have manufacturing technology.The quality of the workforce must also be excellent.

In order to reduce the chance of workers making mistakes, Yiming Group basically uses computer automation control instead.This solves the quality defects caused by the task operation.Fortunately, the purity of the first batch of samples reached 12N. Although it is not the top 13N, it is enough.

Therefore, this time the localization of monocrystalline silicon round rods is a success!

"I'll call them, put the news on the Internet, and blow up the island dwarves."

At this moment, Zhang Nyjin opened his mouth wide, with a smirk on his face.
