From Almighty Scholar to Chief Scientist

Lin Xiao frowned.

But obviously, he couldn't think of anything when he thought so.

After a while, he asked the system directly in his mind: "System, what are those things I saw just now?"

Obviously, the system didn't answer, it was as silent as when Lin Xiao asked where it came from.

But Lin Xiao frowned, and asked again: "System, now I'm spending truth points to ask you, what are those things I saw just now?"

This time, the system finally had a voice: "This question needs to consume 525 truth points, and the current truth point of the host is [-]."

Hearing this response, Lin Xiao scolded directly: "One hundred thousand truth points? Why don't you grab it?"

Of course, he wasn't disappointed either. He knew he couldn't get an answer from the system, but the system needed [-] truth points to answer, so it still revealed a piece of news to him.

What's in his mind is not caused by human's own physiological mechanism, but actually hides a shocking secret.

"Could it be, that's the origin of the system?"

Lin Xiao frowned.

"Why don't you spend more truth points and see if you can see it again?"

Since I was able to see it just now, there is no reason why I couldn't see it this time.

After making a decision, he didn't hesitate, and immediately began to choose what to exchange. In order to ensure that the two times were basically the same, of course this time he also exchanged for a technology worth 15 truth points.

The technical scope to be exchanged is naturally selected within the scope of semiconductors, and now that the technology of lithography machines is no longer lacking, Lin Xiao aimed at semiconductor raw materials.

After Lin Xiao's tests, he finally decided on the technology of exchanging semiconductor packaging materials.

After he confirmed the exchange, 15 truth points were spent, and the feeling of understanding all the truth emerged in his mind again.

And he immediately concentrated all his energy and seriously experienced this feeling.

"Looking" at the infinite mathematical formulas flying in his mind, Lin Xiao tried to capture these formulas again, and this time because he came prepared, he found that he could do this easily.

Soon, he captured several formulas again.

[Hdg^k(X)=H^(2k)(X, Q)∩H^(k,k)(X)]

[Hdg*(X)=⊕kHdg^k(x)]

When he memorized these two formulas with his super memory, the feeling of understanding everything gradually faded away, and he could already see the end of the infinite formulas emerging from the dark depths of his mind, and In just an instant, it completely disappeared.

But Lin Xiao had no time to take care of these things, but concentrated his attention even more, "gazing" into the dark depths, wanting to see those mysterious outlines again.

However, this time, he failed.

He stared at it for a long time, but saw nothing, only the faint light signal that his mind could receive through the thin eyelids.

He opened his eyes, and there was such an expression in his eyes.

What does this feel like?

It's like he found a bug when he was playing the game, and just after having a good time, the bug was fixed when he turned around.

He sighed regretfully, did the system fix this bug?

"How about... try again?"

Is it possible to increase the amount of truth points used?

After a short thought, Lin Xiao decided to give it a try.

This is probably like drawing a card to the top. If you fail to draw, you will continue to krypton gold.

Of course, his situation is slightly different from drawing cards.

"Then this time... let's just double it, and try something with around 2 truth points."

2 times the cost of truth points before, can let him experience the feeling of understanding for a longer time, so maybe he can see it?

So he began to think, what should he exchange this time?

The goal is naturally still on semiconductor technology.

As far as semiconductor raw materials are concerned, basically no one has reached the requirement of 30 truth points, or even 20 truth points. These materials are basically restricted by patents, and Lin Xiao is not lacking in basic knowledge, so raw materials On the other hand, Lin Xiao can basically pass.

"Then, there is only chip design and chip production technology..."

Lin Xiao's eyes lit up immediately.

Compared with chip design, the chip production process is obviously more important.

Why TSMC is so strong is because its chip production process is extremely advanced. Compared with TSMC’s 5nm process and Samsung’s 5nm process, the former is at least half an era ahead, even Samsung’s 5nm process is comparable to TSMC’s 7nm process. Pretty much the same.

The hip pull of Samsung technology is also reflected in the three recent Qualcomm chips, from the Snapdragon 888 to the Snapdragon 888+, and then to the Snapdragon 8gen1. It is also mentioned from time to time, saying that it can fight for a few more years.

Therefore, the importance of the chip production process is also reflected in this.

In the future, after the X-lithography machine is really developed, if an excellent process is not developed to play its role, it will inevitably be criticized by people, saying that it is losing money and making money.

However, how much is the production process of X-lithography machine?

Lin Xiao asked directly: "How many truth points are needed for the 5nm process of X-lithography machine?"

The system replied: "45 truth points are needed."

Lin Xiao frowned, 45 truth points?

This is a bit expensive.

However, after thinking about it, he decided to exchange this technology, anyway, it will definitely be useful in the future.

For the current production process, the 5nm process is completely sufficient, and the chip manufacturing process has reached a critical point, and 5nm is sufficient for commercial use.

What's more, he still doesn't know how the 5nm process given by the system compares with TSMC's 5nm process.

Then he stopped hesitating and directly consumed 45 truth points, and then, the familiar feeling came again.

This time, he also captured a few lines of formulas, and because he spent 45 truth points, he directly captured three lines of formulas this time!

【︶: H^(p, q)(X)＊H^p(X)→H^p＋p(X)】

[N^cH^k(X, Z)=H^k(X, Z)∩(H^k－c)]

[H^(k－c), c(X)⊕...⊕H^c, (k－c)(X)】

After memorizing these three lines of publicity again with his powerful memory, his mind was once again plunged into darkness. However, Lin Xiao still didn't find any strange outlines, and there was only nothingness in front of him.

Lin Xiao sighed, this is very uncomfortable.

Spent a total of 60 truth points and found nothing.

It's a bit of a loss...

Shaking his head helplessly, it seems that this accidentally discovered bug may indeed be a bug, and it has indeed been fixed now.

What kind of secrets does the system hide?

Lin Xiao doesn't know, but maybe he can dig it out in the future?

"Forget it, forget it."

He shook his head, shaking off these regrets, and then turned his head to focus on the two technologies that he spent fifty truth points to exchange for.

Regardless of whether it is a loss or not, these two technologies are real.

First of all, the first technology, that is, semiconductor packaging materials.

Packaging materials are also a big part of the semiconductor industry, and at the same time, this is also a shortcoming in Huaguo's current semiconductor industry chain.

The chip production process is divided into four parts. The first is wafer manufacturing. This wafer manufacturing includes the manufacture of silicon wafers, and also includes subsequent lithography, etching and other links.

The second step is to test the photoetched wafer to ensure that the basic performance of the chip produced by the first step is no problem.

The next third step is encapsulation. The chips produced before are quite fragile. The surface of the integrated circuit with nanometer-level precision may cause a short circuit if a grain of dust enters it, so this requires encapsulation materials to protect it. This circuit is up.

The quality of packaging materials is also very important, so packaging materials are also a hot research field in the semiconductor industry. However, Huaguo still suffered from a late start. Controlled more than 70.00% of the world's market share.

The fourth part after that is the test of the packaged materials. This Huaguo is not behind, of course, because of the relatively low technical difficulty of this thing.

But now, the packaging material given to Lin Xiao by the system...

Lin Xiao showed surprise eyes.

This packaging material is a bit good...

There are three types of packaging materials: plastic, ceramics, and metal. The former is cheap, while the latter two are more expensive. Among them, the main problem of plastic packaging materials is that they are relatively brittle and have poor dielectric loss performance, which is not as good as ceramics.

However, the plastic packaging material given by the system uses a modified epoxy resin and a molding powder doped with a curing agent phenolic resin, which is cross-linked and cured into a thermosetting plastic under the action of heat. In this way, it can be used to make chip packages, and this special modified epoxy resin can be used to solve the shortcomings of the original plastic packaging materials, such as poor dielectric loss performance and brittleness.

Although its cost is more expensive than ordinary plastic packages, it is cheaper than ceramics and metals!

"Another big money maker."

Turning around, he registered the patent, and then gave it to Qizhi Company to sell. Speaking of which, his Qizhi Company has made a lot of money by relying on the patent of polishing liquid and the patent of silicon wafer purification process, and the profit has reached 1 More than [-] million.

Of course, this is also within expectations.

But now this packaging material is more profitable than these two kinds, maybe the combination of the two in the future will not be as profitable as this packaging material.

Lin Xiaomei thought about it, although he can get billions of funds from the country casually now, but obviously, it has to be the money he earns to make people more happy.

He then turned his attention to a second technology.

This is the chip production technology that he spent 45 truth points to redeem.

As for its actual effect?

Lin Xiao couldn't wait to browse the details of this technology, and then he showed a surprised expression.

Make big money!

Chapter 282 Lonely artist?

The 45nm chip process technology of the X-lithography machine exchanged for 5 truth points, Lin Xiao thought before, should be the same 5nm process as those chip processes in the world today.

But in fact, the 5nm process he redeemed from the system is the real 5nm process.

At present, whether it is Samsung or TSMC, the so-called 5nm process of these companies has not actually reached 5nm. People think they are really that awesome.

Ordinary consumers don't know what the physical limit of chips is. If Samsung claims that it is 4nm, TSMC honestly says that it is 5nm. Even if Samsung's 4nm is not as good as TSMC's 5nm, it is hard to guarantee that some consumers will not think that it is [-]nm. Samsung's is even better.

This is why there are reports that TSMC is engaged in both 3nm and 2nm. Obviously, 3nm has reached the physical limit. Even at the 4nm level, some quantum tunneling effects will actually occur, which will affect the actual performance of the chip. Case.

Just like Intel’s CPU is still above 10nm process, because they know very well, no matter how awesome you are bragging about the single-digit nanometer process, in the end, everyone’s actual process is still not up to that level. It's just a matter of chip design capabilities.

What's more, Intel has always been the big brother in terms of CPU. Even though massage shops have suddenly become stronger in the past two years, the gap with Intel in the market is still relatively large, so Intel doesn't care about using the manufacturing process. It's marketing.

However, no matter what, these situations are all because their actual technology cannot reach the real so-called process, and the 5nm process technology that Lin Xiao has exchanged now is a very practical 5nm process, that is, the source of the transistor. The distance between the drains is 5nm, that is, the width of the gate is 5nm.

This is the chip manufacturing process under the most standard definition.

This also means that if they use this process to make chips, they will make the most advanced chips in the world!

They can squeeze more transistors per unit area, and this is almost a one-and-done process.

Because no matter how the production process of other foundries is updated in the future, they need to catch up with their 5nm process first, because theirs is the real 5nm.

Of course, why the 5nm given by the system is actually 5nm must have something to do with their X-lithography machine. After all, according to Lin Xiao’s design, the wavelength of the light source of their X-lithography machine was finally selected as The 3.56nm X-ray, compared with the 13.5nm wavelength of extreme ultraviolet light, obviously has the advantage of their smaller wavelength light source in the preparation of such micro-process chips.

"It's not in vain. I spent 45 truth points."

Lin Xiao felt emotional in his heart.

This is also considered normal, after all, with his current level of various subjects, it takes 45 truth points to solve the technology, it should have such an effect.

From this point of view, although spending [-] truth points did not explore the secrets of the system that may be involved, it is not a loss to be able to exchange for these two technologies.

Of course, the technology of packaging materials will be available soon. As for this production process, we still need to wait for the lithography machine to be manufactured in the future.

Thinking of this, Lin Xiao also let go of his mind, and put these two technologies to the side of his mind first. Anyway, they exist in the system, so he is not afraid to forget them.

Next, it's time to look at other important points.

That is, the few lines of formulas dug out of my mind.

Lin Xiao frowned.

Today, he spent three truth points, which also allowed him to memorize a total of seven mathematical formulas.

The first is the two lines of mathematical formulas when exchanging the double workbench technology.

Lin Xiao recalled these two lines of mathematical formulas in his mind, then picked up the draft paper and pen from the side, and began to write.
