Zheng Ren laughed, the more he remembered the difficulty of having no core available before, the happier he laughed today.

The two were chatting to themselves, but they saw bursts of exclamations erupt on the other side, and everyone was focused on something, as if they were watching something.

"Chief Master Chen, let's go over and have a look?" Zheng Ren pointed over there.

Chen Shen shook his head, he could probably guess what was going on, but he still said, "Then let's go, let's come over and have a look." ”

Today is going to be trial production, and the scene just now should be that the trial chip has come out.

Today's trial production of chips is not the Shenzhou series, that one has to wait a little longer, it is specially designed to confirm the reliability of the process, there is no design difficulty, it is similar to the last time he saw it in the Guoxin Research Institute, he will not go over to join in the fun.

Zheng Ren and Chen Shen squeezed into the crowd wearing dustproof clothing, and now that everyone was wearing dustproof clothing, he was not so conspicuous.

Pushing aside the crowd, Zheng Ren really saw the wafer that had just been sent out of the machine.

It looks the same as a silicon-based wafer, with a very dry surface that has apparently been dehumidified before being removed from the machine.

But unlike silicon-based wafers, this is a 12-inch graphene wafer that uses a substrate to prepare graphene.

The method provided by the system is similar to the current world idea, which is to use semiconductors or insulating materials as the substrate to produce graphene on the substrate, but the difference is that the process of the system is more advanced and convenient, and it also provides a batch manufacturing idea, each batch can produce hundreds of 12-inch wafers, and the considerable output fundamentally solves the problem of wafers.

"Is this really brewing out of the solution? It's amazing too! Several CEOs around Zheng Ren looked at the wafer in amazement.

Even Zheng Ren himself buried his head and observed carefully.

Suddenly, someone asked the engineer next to him, "Isn't this wafer a graphene wafer?" How is it also round? ”

There must be a lot of inconsistency and waste between round wafers and square chips, but there is no way to produce silicon-based wafers into round.

Because this is a limitation of the production process, it can be simply understood that the silicon-based wafer is manufactured on a turntable, and it is naturally rounded like a pancake.

However, graphene wafers are obviously not the same production method as silicon wafers, so how can they also be produced into round?

The engineer who was asked did not hesitate and replied: "Graphene wafers can actually be made into squares, and the reason why they are made into circles is mainly to fit into the current production line. ”

"Aren't your production lines all newly designed and manufactured?" A boss pointed to the machine in front of him, and from the outside observation window, he could see the wafer being soaked inside, which looked old and new and old science fiction.

The engineer who answered pointed to the outside of the factory through the wall: "This is not our production line, but mainly the production line that considers the packaging link." ”

Without waiting for others to ask any more questions, he cleared his throat, knowing that the CEOs present may not necessarily know much about chips, and some people may even come over without even doing their homework beforehand, he said loudly: "After the chip processing on the wafer is completed, we will send the wafer to be packaged, and there will be a cutting step in this link, that is, the chips on the wafer will be removed by the machine." ”

"At this step, the wafer cutting size supported by the machine used is generally only 8 inches and 12 inches, and there is no shape other than a circle, mainly because there were no square wafers in the previous silicon-based chip era."

They can make square wafers or substrates and process chips on them, but then they can't directly use the now established silicon-based chip packaging process.

In this way, when the packaging factory replaces the suitable machine, I don't know how much time it will take.

When he said this, everyone who was there also understood, "So this is the size you made to match the later process." ”

Zheng Ren asked Chen Shen next to him in a low voice at this time: "Chief Master Chen, will we make square wafers in the future?" ”

Chen Shen thought about it, and it was no longer for him to think about the future of production and application, but he still said his thoughts: "It should be, otherwise the losses caused by it will accumulate over time, but we have to wait for the packaging factory to replace the machine." ”

The waste of a wafer is nothing, but the accumulation of sand is not small, especially in the case of carbon-based chip production capacity has not expanded, this practice of rounding up is equivalent to throwing the finished chip directly into the garbage heap, so Chen Shen estimates that in three months at most, Comrade Chen and other companies will definitely force the packaging factory to replace the cutting machine.

The people around him were paying attention to the graphene wafers on the table, Chen Shen also saw several reporters taking pictures or making transcripts, and in the other direction of the workshop, his father was being interviewed.

These reporters are all from big media outlets, and they came here today to help build momentum.

Suddenly, he saw an acquaintance, and the other party happened to look at him.

"Hey! Great God! ”

The man put down the camera in his hand and said hello, until Chen Shen also greeted him and walked over.

"It's been a long time since I've seen the great god, and I recently heard that a documentary team in the station was allowed to enter the base for filming, and I was so envious at the time!" The reporter trotted over excitedly.

This person is Yan Dongsheng, who has only done live broadcasts with Chen Shen before, relying on the live broadcast of tens of millions of people online, he is now a journalist with global influence, and his news reporting on Angjiao or Chen Shen is often regarded as official news by foreigners.

"Maybe one day you'll be able to go in too." Chen Shen comforted.

"I wanted to join the crew of that documentary, but they didn't ask me to ......"

"By the way, can the great god interview you?" Yan Dongsheng was depressed for a moment, and then looked at Chen Shen expectantly.

Chen Shen just glanced at his father's figure in the distance and said, "If it's a problem with carbon-based chips, you can go directly to my father, who is giving an official interview over there." ”

Yan Dongsheng shook his head: "I already have a colleague over there, and I want to ask about the introduction of the rapid photoacoustic scanner by Jieke." ”

"Jaco?" Chen Shen was stunned for a moment, he didn't know much about this matter.

"Yes, Johnson & Johnson Group has obtained the photoacoustic detection agency in the Jieke area, and Jieke has also agreed to cooperate with them to introduce photoacoustic scanners, do you know the specific situation?"

As soon as Yan Dongsheng said this, Chen Shen remembered one thing, the assembly plant of the photoacoustic scanner seemed to have received an order for a foreign trade version recently, and it seemed that they had already begun to ship.

Because the foreign trade version needs to reduce the life of important components such as piezoelectric wafers, He Changfeng, the person in charge of the photoacoustic project, recently reconfirmed with him the "improvement" plan of those parts.

However, there is only so much information he knows, and he doesn't know any more, so he still shook his head and refused Yan Dongsheng's interview.

Seeing this, Yan Dongsheng could only leave with a little loss.

Meanwhile.

On the other side of the continent.

Geco.

The country's specialties are similar to those of the island country next door, and its economic development has been relatively good in recent years.

However, in the large circle of African countries listed before the list of photoacoustic scanner agents for sale, this country on the European continent is as shining and charming as a diamond in the crown.

Compared with those African countries, it is definitely a country with a relatively stable and developed economy that is more promising, so the leadership of Johnson & Johnson snatched the agency of Getac in the round of competition with Siemens.

At this time, at the capital airport, a cargo plane slowly landed on the runway.

The trucks and workers who had been waiting around for a long time immediately rushed up and began to unload the goods, and at the same time a large banner was pulled up at the exit of the goods, which read-

[Congratulations on the arrival of the first batch of photoacoustic scanners at Gecore]

There was also a group of journalists from all over the world, but there were more local journalists from Europe.

Zhang Yuan, the head of the Angular Products Department, had been waiting at the airport for a long time with Johnson & Johnson and local health officials from Jieke, and everyone was immediately excited when they saw the plane landing.

After the above three parties finished unloading and took a group photo in front of the photoacoustic scanner loaded in a large box, the reporters at the scene began to ask questions frantically, or besieged:

"May I ask Mr. Zhang, is photoacoustic detection real? Is the laser power really unmodifiable? In a state of war, would you modify the power of the laser to turn the photoacoustic scanner into a laser weapon? ”

Not only Zhang Yuan alone, but also Charlie, the vice president of Johnson & Johnson Group, was also surrounded by a group of reporters to ask questions.

"Mr. Charlie, what means did you Johnson & Johnson use to enter our domestic market? Is this a covert deal? Do you use donations? ”

Even the health officials in Geeco's own country have been asked tricky questions.

It's just that the three parties present are all old fritters, just selectively answered some questions, Zhang Yuan even answered in Chinese throughout the whole process, as long as someone said that he couldn't understand, he clicked on the Lingxi headphones he wore on his ears and signaled the other party to buy one.

Now Lingxi headphones have opened up the global market, and they are not expensive, which is an important profit point for the edges and corners, but the translator has been gradually eliminated.

After dealing with this group of reporters, the photoacoustic scanner in the box went smoothly to the hospital where it was scheduled to be installed, and Zhang Yuan and Charlie got into the car they followed, and then they breathed a sigh of relief.

The two looked at each other and smiled.

"Those old stubborn journalists in Europe are really tough enough." Charlie said.

"It could be that they find it hard to accept reality."

Zhang Yuan shrugged his shoulders and let the driver in front of him drive.

The somewhat atroverted attitude of these journalists reflects the rejection of the two external forces by the local forces.

Angjiao and Johnson & Johnson, both forces outside the continent, are now entering their own domestic medical market with great pois, and may also set off a big change.

This situation is not happy at all.

As for those reporters other than Gecor, they see the future of their country from this incident.

They have not forgotten that they still hold a large number of countries in their hands and have not sold them, and there are their own countries on them......

Sooner or later, the situation will happen in their own country.

Under the sadness of the dead rabbit and the fox, their attitude is naturally not good.

Therefore, during this time, many people with lofty ideals have been calling for the country to invest in the research of photoacoustic scanners and strive for the independence of photoacoustic detection.

No matter how bad it is, I also hope that my country can buy back the agency from the edge and corner, and not let my handle fall into the hands of others.

As Chen Shen expected, the photoacoustic scanner quickly became relevant to the international situation after its launch.

Even Edge's sale of Jieke's agency rights to Johnson & Johnson, and the promotion of photoacoustic detection into the Jieke market, is also related to their recent domestic actions, which is also a warning.

Let them know not to sell things out blindly.

Now everyone can see that Geeco is losing its own medical testing market, and most of the money that their citizens spend on medical testing every year may be divided into the hands of Angjiao and Johnson & Johnson in the future.

However, in the face of this situation, the local medical companies of Jieke have no way, and it is impossible for them to develop photoacoustic scanners and photoacoustic algorithms, nor can they inhibit the introduction of photoacoustic scanners.

After all, Johnson & Johnson is not a vegetarian, although they have a home advantage, but they can't fight the flying cross-river raptors, and the public is also looking forward to photoacoustic detection, after all, photoacoustic detection can greatly reduce their medical burden.

In such a situation, some medical companies simply turned to Johnson & Johnson and Edge, wanting to continue to make money by relying on their own medical channels in China.

And that's just the beginning.

With Jieke as a starting point, the medical testing market of the entire continent and even the world will slowly fall, and it will only take time.

If you want to reverse this situation, you must either successfully develop your own photoacoustic detection technology, or you can buy the photoacoustic detection agency in your own country with the investment of domestic enterprises.

It's just that the decision to sell or not is on the side of the edges......

The installation of Jieke's photoacoustic scanner is very smooth, they imitate the model of the magic capital, and transform an abandoned hospital into a photoacoustic testing center, and there is an endless stream of people who come to experience scanning every day, and even people from neighboring countries come to pay for the experience, so that Jieke can have an income of more than 100,000 euros every day.

According to the conditions negotiated between the two companies and Jieke local cooperation, the main purpose of photoacoustic detection is to cooperate with the expansion of the AI diagnostic database, so Johnson & Johnson can not charge a penny except for the cost, and the data processing fee of each inspector is also halved.

As for the money paid by tourists for the experience, Edges and Johnson & Johnson do not take commissions, only the normal data processing fee, which can be regarded as a consolation.

Of course, piezoelectric wafers and other repair items that are most prone to wear and tear will not be discounted at all.

According to the local detection volume of Jieke, only two piezoelectric wafers are used in a day.

So these hundreds of thousands of euros still have to go back to the angular pockets after the final tossing......
