A big country of aerospace with black technology

Metal chemical vapor deposition is not a very groundbreaking method.

Talk about it.

These methods of crystal growth can actually be summarized in just a few ways.

Many laboratories around the world have conducted research on these methods.

What really affects the application of gallium oxide.

It’s actually how to do large-scale production.

and industrial production.

We want gallium oxide substrates to enter practical applications.

Small-sized crystals like particles have no effect.

Because this cannot be used as a substrate material for high-frequency components.

It must be more than two inches to have a certain use value.

Otherwise, even basic cutting will not be possible.

"Contact me a pressure vessel manufacturer."

Zhang Xingyang took his eyes away from the computer and gave Lidya Su an instruction.

Although Su Xiao is currently the head of the Materials Experiment Center.

But in front of Zhang Xingyang, it seems that she will always be the newcomer who just entered the materials industry.

"Any special requests?"

After hearing this, Su Xiao did not ask why, but directly asked Zhang Xingyang if he had any requirements.

If Zhang Xingyang wanted to tell her, he would naturally do so.

If you don't want her to know, there's no point in asking.

"It's enough to have first-level manufacturing qualifications. If possible, special-level qualifications are the best."

Zhang Xingyang thought for a while and said.

The metal vapor deposition method requires the use of a high-temperature reactor.

Although ultra-high pressure is not required, the reaction temperature needs to be above 1,200 degrees.

The institute currently does not have a particularly suitable reaction vessel.

"I understand, I will contact you."

Lidya Su nodded and said.

The Materials Experiment Center often requires some special pressure vessels.

There are also some familiar pressure vessel partners.

But in terms of qualifications, Su Xiao really doesn't know if they have first-level qualifications.

So he didn't reply directly to Zhang Xingyang, but said he wanted to get in touch.

"Is there anything else you want me to do?"

Lidya Su said immediately.

"No, you go and do your work first."

Zhang Xingyang turned his head back to the computer screen and looked at several different interfaces.

There are at least a dozen pages open on the computer screen at the same time.

There are dense symbols and circuit diagrams on every page.

Look at it as someone else.

You might get dizzy just by looking at it.

But Zhang Xingyang was able to look at these dozen documents.

These are articles related to the industrial production of gallium oxide.

They were all written by Zhang Xingyang during this period.

But it hasn’t been published yet.

The experiments haven't even been done yet.

In fact, if you look carefully, you can find it.

Some key data aspects of the article are blank.

It seems that just waiting for the data to be filled in can be completed.

"Then I'll get busy first."

Lidya Su said this, turned around and left the office.

Only when he was about to go out, did he look back at Zhang Xingyang.

But all I saw was that he was still immersed in the computer interface.

He didn't raise his head to look at her.

So I left the office feeling a little disappointed.

The development of metal vapor deposition method is actually not particularly complicated.

Even without Zhang Xingyang, domestic scientific researchers could complete ultra-large-scale research in more than ten years.

What Zhang Xingyang did was to advance this time.

"After the current industrial production of gallium oxide, it should be able to meet our power period requirements."

Zhang Xingyang kept calculating the design of the gallium oxide converter.

And thinking about subsequent applications.

There are two main ways to apply gallium oxide.

The first is the use Zhang Xingyang currently wants.

Plays an important role in the power period.

This type is generally used as an extension piece.

Epitaxial parts are not single crystals.

It has a substrate, if gallium oxide is used as an epitaxial component.

The base is mostly silicon carbide.

Its advantage is that its oxygen content, carbon content, and defect density are very low.

This results in a very high reliability of the device and it is difficult to be damaged due to leakage and other issues.

for example.

The original power-generating satellite required professional astronauts to enter the satellite about every three months to replace the damaged converter.

Then after replacing gallium oxide.

This maintenance cycle can be approximately eight months.

Attrition rates dropped more than twice.

In addition, the energy consumption of the device will be reduced by more than 60%.

It can incidentally solve the satellite heat dissipation problem that is currently causing Zhang Xingyang some discomfort.

After all, cooling systems and coolant aren't cheap.

And they need to be replaced regularly.

The astronauts perform regular maintenance on the contents, in addition to replacing the converters.

It is to replenish the lost coolant.

The second application is also of some use to the current Zhang Xingyang.

That is to directly manufacture logic chips or storage chips.

This is not an epitaxial film.

It is a single crystal polished piece.

The research institute is currently located in the Chip Industrial Park in Jiangcheng.

Just broke ground.

If the gallium oxide single crystal polishing sheet is successfully developed.

It can be used as a core product of the chip industrial park.

Regardless of logic chips or memory chips.

It is very useful for domestic use.

Especially logic chips.

If the development is successful.

It can solve a problem that Zhang Xingyang has not solved before.

The problem of intelligence of sub-group warheads.

"Have you found a production unit with relevant qualifications so quickly?"

Zhang Xingyang looked at Lidya Su with some surprise and said.

It was only half a day before I made my request.

Found it so quickly.

It's actually a bit unexpected.

"Luckily, one of the relevant companies we cooperate with has first-level qualifications."

Su Xiao put a company-related document on Zhang Xingyang's desk and said.

“Previously we needed a large reactor to verify the industrialization of boron nitride.

I had contact with them at that time.

But later the project encountered some problems and was shelved.

However, their contact information was retained. "

Boron nitride can actually be regarded as a fourth-generation semiconductor.

It also has ultra-wide bandgap properties.

However, the development of boron nitride is slightly more difficult.

It belongs to a research direction that is even more niche than gallium oxide.

However, boron nitride has several different allotropes.

Some materials can serve as aerospace-grade heat shields.

It is estimated that Su Xiao and the others were preparing to develop the industrial synthesis of boron nitride for this direction.

The hydrothermal synthesis method of boron nitride also requires high-temperature and high-pressure vessels.

"Have you contacted them?"

Zhang Xingyang said while flipping through the other party's corporate information.

Judging from the information, the other party's qualifications are indeed first-level.

And it is an established first-class pressure vessel manufacturer.

The most important thing is that the reputation is very good.

The production was easy and there were basically no accidents.

"Already contacted, their people will arrive tomorrow."

Lidya Su nodded and said.

The other party still attaches great importance to this order.

Except that there weren’t many orders for pressure vessels during this time.

There is another important reason.

The reputation of the institute is very good.

The other party obviously knew the relationship between the institute and the current materials giant Longteng Group.

If you can make some connections.

It will be very beneficial to their future development.

Longteng is a leader in the field of new materials.

There is a huge demand for pressure vessels.

In the past, their pressure vessels basically came from pressure vessel manufacturers in Donghai City.

This can also be regarded as an exchange of interests.

Donghai City has given Longteng Group a lot of preferential policies.

Longteng Group reciprocated the favor and brought a lot of orders and consumption to the local area.

However, the institute and Donghai City do not have a deep relationship.

Therefore, I did not look for a pressure vessel manufacturer in Donghai City.

Instead, I found a pressure vessel company that had a good relationship with the institute itself.

"They are quite fast."

Zhang Xingyang also finished reading the other party's information at this time, raised his head and said.

"Not too fast is a good thing, to be able to see large-sized gallium oxide wafers faster."

At this time, Zhang Xingyang revealed a little about the purpose of customizing the pressure vessel.

“Are we going to find new ways to produce gallium oxide?”

Lidya Su's eyes lit up and she asked a little fast.

"How big can it be?"

During this period, Su Xiao spent a lot of time on the guided model method.

According to her own estimation, if she continues along this route.

It will take at least two to three years to complete the development of a two-inch chip.

In a short period of time, it is almost impossible to complete large-scale development.

"I devised a new method of production."

Zhang Xingyang said:

"But the specific effect will not be known until after the experiment."

"According to the current situation, the finished product can be at least four inches in size."

Four inches is nothing to Zhang Xingyang.

All I can say is that it is barely enough.

But for Lidya Su, it was a bit shocking.

They worked very hard in the experimental center and finally raised it to a level close to two inches.

And it will take at least two or three years to remove these two words.

Zhang Xingyang suddenly showed that he could prepare four-inch gallium oxide wafers, which was hard for him to accept.

"Then what we did before was in vain?"

Lidya Su said with some frustration.

After working so hard for so long, I suddenly found that my work was not worth mentioning.

It was still a bit big of a blow to her.

"That's not true."

Zhang Xingyang said without any hesitation:

"The guided mode method does have its advantages."

“Metal vapor deposition can only be used for epitaxial wafers.

If you want to produce qualified single crystal polished wafers, you can only rely on the guided mold method. "

After listening, Lidya Su thought about it for a while and then reacted.

Indeed.

For single crystal polished wafers, there is no way to perform metal vapor deposition.

Mass production can only be achieved by relying on the guided mold method.

"That's true, but the process of the guided mold method is indeed a bit difficult."

Lidya Su frowned slightly and said:

"According to the current progress, it will take us at least two years to complete process development."

"Two years is not a long time for us."

Zhang Xingyang said:

"We can definitely afford to wait."

——

"Hello, Dean Zhang."

The next day, in the conference room of the institute.

An honest-looking middle-aged man said hello kindly.

"Chen Shiqi?"

Zhang Xingyang stretched out his hand and shook it.

"Exactly down there."

The other party smiled and said.

"I didn't expect Dean Zhang to be so young."

"You are really young and promising."

Zhang Xingyang is actually quite old.

But his face has always looked relatively childish.

Without looking into those eyes.

At first glance, many people would think that he is a graduate who has just stepped out of school.

"Thank you for the compliment."

Zhang Xingyang smiled and said.

In fact, many people have said that he has a childish appearance.

But once you get to know him a little deeper, you won't care about this.

"Let's get straight to the point."

"Your company has the first-level pressure vessel manufacturing qualification, so it should be able to manufacture a reactor that meets these requirements, right?"

After speaking, Zhang Xingyang handed the other party an A4 paper with specific parameters written on it.

Before Chen Shiqi came, he inquired about Zhang Xingyang's personality.

Although I didn't find out much.

However, I still got some valid news.

The most useful thing is that people in the institute are very efficient.

It's best not to do anything messy.

It can be inferred from this that Zhang Xingyang, as the dean.

I guess so too.

So Chen Shiqi didn't say much, but directly picked up the piece of paper and read it.

Can be sent out by the company for negotiation.

Chen Shiqi is relatively familiar with some technical aspects.

I finished reading the above very quickly.

I thought about my own production capacity for a while.

The answer: "We can indeed produce, these are not too big problems for us."

In fact, domestic pressure vessel manufacturers are very involved.

There are many reasons for this.

The Dragon Kingdom is a large agricultural country.

Modern agriculture involves numerous chemical productions.

Just like ammonia synthesis.

This technology is available to most countries in the world.

These are all technologies that are difficult to implement.

The most important reason for this is.

Synthetic ammonia requires the use of numerous pressure vessels.

Especially the very large ammonia production line.

For example, the 800,000-ton production line previously put into production in China.

They are among the best in the world.

The number of such production lines in China is quite large.

A glimpse of the leopard shows that domestic pressure vessel manufacturers are also very strong.

Chen Shiqi's pressure vessel production company does not have special qualifications.

Some very large pressure vessels cannot be produced.

At present, some small and even medium-sized chemical plants are being eliminated in China.

Their life is not very easy either.

If you want to survive, you must either keep rolling at home or find a way to go overseas.

Some third world countries still have considerable demand for small and medium-sized pressure vessels.

But Chen Shiqi and his company obviously do not have such channels.

This is why they attach so much importance to this business.

If you can take this opportunity to catch the Longteng Group's ship.

Things will get better for them for a while.

"Roughly how long will it take?"

Zhang Xingyang asked a more important question.

Chen Shiqi thought for a while and then replied: "It will take about half a year."

"It's too long."

Zhang Xingyang shook his head and said.

Chen Shiqi wanted to explain: "Dean Zhang, it does take a certain amount of time to manufacture pressure vessels."

"Twice the price, three months."

Zhang Xingyang didn't care too much and said directly.

"If we can't do that, there's no point in continuing the conversation."

Chen Shiqi's brain was running at high speed.

If the factory works in three shifts, it can actually be completed in three months.

After thinking for a while, I had to take the institute route.

"Okay, we agreed." Chen Shiqi said with determination.
