Spark

After the meeting with the Spark team, Chen Nian returned to his residence.

At this time, it was already 10 o'clock in the evening, Chen Nian's body was extremely exhausted, but his mind finally settled down.

In fact, what he is most afraid of is not the slow development of technology, nor the lack of his own source, but the technical foundation and technical principle, which cannot be produced due to various reasons.

In this day and age, everyone doesn't have a deep feeling, but he has experienced it personally!

I remember that at that time he was still working in a certain military enterprise, and there was a project that needed to be cooperated with a private enterprise, but when the company issued a bidding announcement, very few companies actually responded.

The company I work for is obviously the high-quality customer who pays the most and has the least trouble, and the project returns are also very generous, but no one dares to come.

Why?

the reason is simple.

Once there is a business relationship with the company I work for, under that big hand, the whole company may be destroyed in one fell swoop.

In the end, only three leading companies insisted on bidding against the strictest restrictions, and their ideas were simple:

At worst, it will close down after finishing this ticket.

As a result, the company that won the bid almost collapsed, with a large area of ​​business defaulting, the supply chain was broken, and funds were extremely tight.

At the most difficult time, the person in charge of that company sold all his cars and rode a shared bicycle to work every day.

If it weren't for the income from this project and the special policies of the State-owned Assets Supervision and Administration Commission, it would be impossible for him to survive.

Therefore, it cannot be blamed for domestic companies to be alone.

If you want to blame, you can only blame yourself for not being strong enough to protect these little brothers under him.

That feeling was even more aggrieved than a real conflict.

Now that he is alive again, Chen Nian will never allow such a thing to happen again.

Even, he wants to do more.

If you can suppress us, can't we counter it?

As long as my hang is big enough, as long as our development speed is fast enough, one day, our technology will completely surpass yours.

At that time, the offensive and defensive Yi Xing will not be begging you, but you begging us.

Thinking of this, Chen Nian felt a strong sense of urgency again.

He ran to the bathroom to take a quick shower, and after a few minutes of rest, he sat down at the desk again.

The progress of learning silicon materials is not too slow, and now he has mastered all the basics of crystal geometry, and has entered the fourth part of the study of crystal defects.

Among them, he is most concerned about dislocation defects and oxide fog defects, because these are the most common defects in the manufacturing process of single crystal silicon, which are mainly caused by the influence of process and equipment.

If you understand the principle, maybe you can reduce the requirements for analyzing the source point of the single crystal furnace...

Therefore, in the next two hours, Chen Nian reviewed all the knowledge related to crystal materials, memorized all the knowledge points, and became familiar with the principles and application methods.

But when he turned on the system to see the analysis requirements of the single crystal furnace, he found that the analysis source requirements had not changed at all.

What's going on here?

It shouldn't be.

Chen Nian frowned, looking at the notes he had just taken in doubt.

Is it because the information density is not enough?

But according to his previous experience, if it is highly relevant knowledge, the bonus to price reduction is still quite large, and there shouldn't be no reaction at all.

Even if there is 0.001, it is considered normal.

Or... need an application?

Thinking of this, Chen Nian thought for a moment, then picked up the pen again and began to write on the paper.

Single crystal furnace technical point 1: Since impurities can cause defects such as twins, embedded crystals, holes, inclusions, hydrogen-induced defects, and COP, it is extremely important to clean the interior of the single crystal furnace. It is necessary to ensure that the main furnace chamber, isolation valve, auxiliary The airtightness of the furnace chamber, under the current technical conditions, you can choose to use perfluorinated rubber for vacuum sealing...

Single crystal furnace technical point 2: If the temperature gradient of the thermal field is too large during the growth of single crystal, large thermal stress will be generated in the crystal, which will cause dislocation defects inside the crystal and cause them to proliferate. To avoid such situations, The single crystal furnace can use a double-tube flange structure, cooled by water, and it is best to use water barriers to ensure uniform cooling...

Single crystal furnace technical point 3: The reason for the occurrence of micro-defects is...

Chen Nian wrote while thinking, the information was not analyzed by the system, but he deduced it bit by bit based on his previous studies, including the experience he had acquired in the manufacture of new materials.

The part about vacuum sealing is a cliché, but the double-tube flange structure + water-separator cooling is the most suitable treatment method after his own consideration.

That is, it is his original design.

But of course, such a design is just an idea, or a direction, which is far from meeting the requirements of being able to draw a structure diagram and output it to the application stage.

Chen Nian didn't intend to do this either, because complex numerical deduction and numerical adjustment would take too much time, and it would be better cost-effective than direct analysis.

The time saved is used for learning and experimenting, and the income from the number of source points will be higher.

I just don’t know if it’s possible to reduce the demand for source points by only doing this step... even 0.01 point is fine.

With this in mind, Chen Nian opened the system interface and re-scanned the single crystal furnace, first to see the latest source consumption.

And when that number appeared in front of him, he almost jumped out of his chair with joy.

The original 2.9 source point quantity requirement has become 2.72!

That is to say, every useful technical point written by myself reduces the source demand by 0.06 points on average!

If you can reason all the knowledge points you have mastered to the application, wouldn't you have the opportunity to directly reduce the source point consumption to 0?

Get started now!

Chen Nian got up immediately and took two books from the shelf.

A Basics of Semiconductor Silicon Materials.

A basis of mechanical manufacturing technology.

While absorbing the theories he needed from the textbooks on silicon materials, he tried to put his ideas into practice and realize them with manufacturable devices.

Such reasoning is of course extremely crude, extremely inaccurate, and may even be wrong.

However, he couldn't stop him from hanging up!

Whether an application design is useful or not can be seen at a glance if there is any change in the source consumption quantity!

It took less than 20 minutes for him to deduce the fourth useful design direction, which brought another price reduction of 0.05 source points.

Good guy, it's really interesting.

The more Chen Nian wrote, the more excited he became. Before he knew it, the sky outside had already lit up.

After a whole night, Chen Nian finally sorted out all the things he had learned at this stage, and with the help of the system, tried his best to deduce the way of application.

There are a total of 13 points, two of which bring little price reduction at the source point, probably useless, but 11 of them are usable.

At this time, the source point consumption of the analysis single crystal furnace has been reduced from the initial 2.9 points to 2.24 points.

A total of 0.66 source points were talked about.

In addition to the 1.72 source points that I saved originally, there are only 0.5 source points left from the analytical single crystal furnace.

The speed of progress far exceeded Chen Nian's expectations.

According to this progress, it is estimated that within one month, the problems of the single crystal furnace and the diffusion furnace can be solved.

Then, in one to two months, we will have the ability to manufacture T/R modules.

At that time, as long as you have saved enough sources to analyze the digital array radar itself, you can directly start the research and development and manufacture of the digital array radar.

Digital Array Radar...

This thing will not only allow our Canglong fighter to evolve directly to a full body, but will also lay the foundation for our large-scale early warning aircraft business.

What follows is a more complete data link system and stronger detection and early warning capabilities.

At that time, your EP-3E still wants to touch porcelain? !

The radar detection range can reach up to 900 kilometers. From the moment you take off, I will stare at you!

You will be disgusting, we will not be right?

Chen Nian had a big heart, and he lay down on the bed contentedly, and was about to sleep for two hours to catch up on sleep, but before he could close his eyes, the phone rang.

He got up helplessly, thinking that Chen Guo had something to inform him, but unexpectedly, there was an unfamiliar voice on the other end of the phone.

Hello, Chen Nian? I'm Yang Wei.

Yang Wei...who is it?

Chen Nian didn't remember the name for a while.

I don't seem to have touched it before.

Yang Wei from Institute 611.

Oh, 611...

Chen Nian nodded subconsciously, and then suddenly realized something was wrong.

Wait a moment?!?

611, Yang Wei??

The addition is only added on weekends, and it is estimated that it will not be finished at one time.

I am a hard-working laborer, screwing screws during the day on weekdays and coding all night at night.

No kidding.

If you don’t believe me, you can ask my old readers, my editors used to tell me to sleep more, for fear of my sudden death
