From all-round academic master to chief scientist

【ζ(1/2+it)=O(t^e)】

【ζ(1/2+it)/(t^e)=O（√plnp）】

Looking at these two formulas that were probably leaked due to an accident in the system, or because there was a real bug in the system, Lin Xiao naturally thought again of the human-like figures he had just seen in the darkness deep in his mind. Outline.

What are those things?

Is it related to the system?

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 were those things I saw just now?"

Obviously, the system did not answer, and was as silent as when Lin Xiao asked where it came from.

But Lin Xiao raised his eyebrows and asked again: "System, now I am spending truth points to ask you, what are those things I just saw?"

This time, the system finally spoke: "This question requires 100,000 truth points, and the host's current truth points are 525."

Upon hearing this response, Lin Xiao scolded directly: "One hundred thousand truth points? Why don't you go and grab them?"

Of course, he was not disappointed. He knew that he would not get an answer from the system, but the system needed a hundred thousand truth points to answer, so it still revealed a piece of news to him.

What was in his mind was not caused by human physiological mechanisms, but actually hid a shocking secret.

"Could that be the origin of the system?"

Lin Xiao frowned.

"How about spending more truth points and see if you can see it again?"

Since I could see it just now, there is no reason why I can't see it this time.

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

The technology range to be exchanged was naturally selected within the semiconductor range, and now that there is no shortage of photolithography machine technology, Lin Xiao targeted semiconductor raw materials.

After Lin Xiao's testing, he finally determined the exchange of semiconductor packaging material technology.

As he confirmed the exchange and spent the 15 truth points, the feeling of understanding all the truths 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 once again tried to capture these formulas, and this time because he came prepared, he found that he could do it 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 relied on his super memory to memorize these two formulas, and this feeling of understanding everything gradually faded, he could already see the end of the infinite formulas emerging from the dark depths of his mind, and Just for a moment, it completely disappeared.

Lin Xiao had no time to worry about these things, but focused more on "gazing" into the depths of darkness, hoping to see those mysterious outlines again.

However, this time, he failed.

He stared for a long time and saw nothing, only the faint light signals that his mind could receive through the thin eyelids.

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

What does this feel like?

It's like he found a bug while playing a game, and just as he was enjoying himself, the bug was fixed when he turned around.

He sighed with pity. Did the system fix this thing that was considered a BUG?

"How about... try again?"

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

After a short period of thinking, Lin Xiao decided to give it a try.

This is probably like getting stuck in drawing cards. If you don't win, you will continue to earn money.

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

"Then this time... let's just double it. Try around 30 truth points."

Spending twice as much truth points as before would allow him to experience the feeling of understanding for a longer period of time. In this way, maybe he could see it?

So he started thinking, what should he exchange for this time?

The goal is naturally still to focus on semiconductor technology.

As for semiconductor raw materials, basically none of them has reached the requirement of 30 truth points, not even 20 truth points. These materials are basically restricted by patents. Lin Xiao is not lacking in basic knowledge, so raw materials In terms of performance, Lin Xiao can basically pass.

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

Lin Xiao's eyes suddenly lit up.

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

Why TSMC is so strong is because its chip production technology is extremely advanced. Comparing TSMC’s 5nm process with Samsung’s 5nm process, the former is at least half an era ahead. Even Samsung’s 5nm process is just as advanced as TSMC’s 7nm process. Pretty much the same.

The pull of Samsung's technology is also reflected in Qualcomm's three recent chips, from Snapdragon 888 to Snapdragon 888+, and then to Snapdragon 8gen1, all of which have overturned, so much so that Huawei's Kirin 9000 released in 2020 Chips are also mentioned from time to time, saying that they can still compete for a few more years.

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

In the future, after the X-ray 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 they are losing money and making money.

However, how much production process is required for X-ray lithography machines?

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

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

Lin Xiao frowned, 45 truth points?

This one is a bit expensive.

However, he thought about it and decided to exchange it for this technology. It would definitely be needed in the future anyway.

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

Moreover, he still doesn’t know how the 5nm process provided by the system compares with TSMC’s 5nm process.

Then he no longer hesitated and directly consumed 45 truth points, and then the familiar feeling came again.

This time, he also captured several lines of formulas. 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 remembering these three lines of announcement again with his strong memory, his mind once again fell into darkness. However, Lin Xiao still did not find any strange outlines, and there was only nothingness in front of him.

Lin Xiao sighed, this was very uncomfortable.

I 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 secrets does the system hide?

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

"Forget it, never mind."

He shook his head to get rid of these regrets, and then turned his attention to the two technologies that he had spent fifty truth points to redeem.

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

The first is, the first technology, which is semiconductor packaging materials.

Packaging materials are also a major player in the semiconductor industry. At the same time, this is also a shortcoming in China's current semiconductor industry chain.

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

The second step is to test the photo-etched wafers to ensure that the basic performance of the chips photo-etched in the first step is OK.

The third step is to encapsulate. The chips produced before are quite fragile. The surface of the integrated circuit has a precision of nanometers. If a particle of dust enters, it may cause a short circuit in the circuit, so this requires packaging materials to protect it. This circuit.

The quality of packaging materials is very important, so packaging materials are also a hot research area in the semiconductor industry. However, China still suffered from a late start. In addition, the island country next door has accumulated enough technology to almost firmly It controls more than 70% of the world's market share.

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

And now, the packaging material the system gave Lin Xiao...

Lin Xiao showed a look of surprise.

This packaging material is a bit good...

There are three types of packaging materials: plastic, ceramic, and metal. The former is cheap, while the latter two are relatively expensive. 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 provided by the system uses a modified epoxy resin, and is internally doped with molding powder of curing agent phenolic resin, which cross-links and solidifies 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 solve the shortcomings of poor dielectric loss performance and relatively brittleness of the original plastic packaging materials.

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

"It's another big moneymaker."

He registered the patent later and handed it over to Qizhi Company to sell it. Speaking of which, his Qizhi Company made a lot of money by relying on the polishing fluid patent and the silicon wafer purification process patent, and the profit has reached 1 More than 100 million.

Of course, this is also expected.

And now this packaging material is more profitable than these two. Maybe in the future, the two combined will not be as profitable as this packaging material.

Lin Xiao thought happily that although he could easily get billions of funds from the country now, obviously, the money he earned himself would be more enjoyable.

He then turned his attention to the 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 an expression of surprise.

Make a fortune!
