I asked you to save a bankrupt factory and you became the richest man in the world.

Chapter 557: 419-420: New mobile phone development! (4000 words)
Liang Mengsong was also stunned when he heard this.

The speed of this Hillhouse chip is too fast!
This is a desperate attempt to protect one's own capital chain!

He also knew about Hillhouse Chip's chip stacking solution.

Not just knowing, but being very clear about it.

This thing is really not simple!
If the chip stacking is a simple 1+1, the process is indeed very simple as long as the chips are flipped together.

But the consequence is that the computing power utilization is very low.

1+1=1.3.

You try your best to stack the chips, but the two chips together can only achieve 1.3 of the effect, which is really meaningless.

This actually involves the most advanced packaging technology of this era.

What Hillhouse Chip is currently dealing with is a 3D core packaging method called flip chip wire bonding.

Use this method.

Its performance has ensured 1+1>1.8 in multiple tests.

TAIC does not have a standard process for this new type of thin film called ABF, but instead uses a process more related to silicon manufacturing.

This requires the chip manufacturing plant to use Tokyo Electron coaters/developers, ASML lithography tools, and Applied Materials copper deposition tools to photolithographically define the redistribution layers of the chip.

at this time.

The redistribution layers (RTL) are smaller and denser than most OSATs can produce, thus accommodating more complex routing.

In other words.

In theory, advanced packaging is also an advanced process technology.

Advanced process technology can effectively reduce power consumption to 2.

This route is to rebuild multiple chips into one chip.

The only difference is that before it was engraving on silicon wafers, now it is outlining.

This thing, even Taiwan and Taiwan have never played it!

I don’t know how to build this industrial production line, and I don’t know if it can be built.

Now let’s not talk about him, even for Hillhouse’s chip design sector, it will take more than a day or two to develop it.

It will take at least three years!

Because this redistribution layer needs to start from the underlying logic!

However, there was no sign of the self-destruction of Xida three years ago, there was almost no obstacle to the normal exchange of world trade, and there was no voice saying that an ordinary company would be self-destructed.

But. . .

Why did Hillhouse Chip start secretly developing such a thing three years ago?

This is no ordinary spare tire.

To develop such a technology from scratch, at least 500 million yuan of funds are needed.

If there is no self-commitment, there is no doubt that this is a very useless and thankless project.

Why would Gao Huaijun, his own boss, take on such a thankless project?

A prophet?
Thinking of this, Liang Mengsong couldn't help but turn sideways and secretly glance at Gao Huaijun who was listening carefully to Min Weiguo's report in front of the stage.

A look of surprise appeared on his face.

This is simply...

God!

However, Gao Huaijun ignored the little thoughts of the leaders below.

He continued, “The Hillhouse Mate Series cannot stop like this!”

"The next generation product, as usual, will be the Mate 14, but this number doesn't sound good, coupled with the recent suicide incident."

"Although I am not superstitious about this, Chinese people are more or less taboo about this kind of thing."

“So, I decided to call the latest series of products mate20!”

Speaking of this, Min Weiguo and others in the audience all showed excited smiles on their faces.

As for the Mate series and the P series, they actually have no idea whether to continue to make them or whether to continue to play with them in the future.

If Gao Huaijun had not mentioned this matter on his own initiative, it would probably have been deliberately delayed.

After all, you really don’t know whether the high-end chips produced by Hillhouse Chip Factory are reliable.

This really makes people questionable.

But now that Gao Huaijun has brought up this matter, it can be seen that the matter has been finalized.

"Let me tell you how the latest mate 20 series will be designed."

After Gao Huaijun finished speaking, he rarely asked Feng Xiaochen to open the PPT on the side and displayed it.

Although Gao Huaijun controls the research and development direction of each company, he has been directly involved less and less recently.

This is the first time in recent years that the company has taken control of the R&D ideas.

Everyone is looking forward to Gao Huaijun bringing something different to this phone!

The design concept of this generation is the same as the recent Mate series, which is to place the camera on a ring, which also adheres to Gao Huaijun's long-standing design concept.

The ring is a bit bigger than previous generations, and at first glance it doesn’t look as good as the previous generations.

But Gao Huaijun’s designs have a magic – they may not look good at first glance, and may even seem ugly, but the more you look at them, the more they please the eye and become more and more beautiful.

After looking at the back of this phone for a long time, I feel that it is grand and elegant.

The executives below couldn't help but nod secretly.

Just this appearance.

That's it!

"I don't want to change the appearance much, but I have a small idea about tempered glass, which is to prevent it from falling!" Gao Huaijun said lightly.

Fall-proof?!
The executives below all looked at Gao Huaijun with different expressions.

Generally speaking, the core cost structures of a mobile phone are the chipset represented by SOC, the battery pack, and the camera group. As for the others, they are basically homogenized by different companies and are almost the same.

Almost all the mobile phones you see on the market look like that, pretty much the same!
As for putting the cost on tempered glass...

is it necessary?

However, they think that this mobile phone is currently in an unknown and chaotic state, and the key still depends on whether Hillhouse chip factory can deliver the results.

If it's not powerful enough, you will probably have to use low-end chips.

In this case, the chip used in the flagship phone is the same as that used in the low-end phone. If this product does not have major breakthroughs in other aspects, that’s it.

Gao Huaijun explained the core concept of the product material he needed, which is strong anti-fall performance!

From being dropped, soaked, and bumped at the beginning, to being pierced by nails, run over by a car, and thrown into a washing machine, the glass of this phone is needed to be foolproof!
Gao Huaijun likes to test Hillhouse’s various products using his mobile phone.

Generally speaking, the P series and mate series will be used to make management suggestions for this mobile phone from the user's perspective.

Gao Huaijun hopes that this tempered glass, through the nano-crystal glass material, will generate billions of high-strength nanocrystals, bringing up to 10 times the drop resistance. According to Gao Huaijun, it is best to iterate and upgrade the glass formula composition, supplemented by the upgraded composite ion strengthening technology, so that the drop resistance can be further improved to 20 times that of ordinary glass.

The whole machine is ultra-reliable in terms of drop resistance, scratch resistance and waterproofness, allowing consumers to fully enjoy the ultimate user experience brought by the bare machine.

Customers don’t need to apply tempered glass and don’t have to worry about the phone screen getting scratched.

The hardness of ordinary tempered glass is roughly around level four, but this high-strength tempered glass must at least reach level six!

This type of glass is actually microcrystalline glass. In the field of microcrystalline glass, foreign companies have always had a very high market share, and the technology is mostly occupied by foreign manufacturers.

It is generally used for high-strength bullet-proof glass.

Thick, but heavy.

However, neither the material rigidity nor the material thinness could meet Gao Huaijun's requirements.

An executive who was in charge of collecting screens couldn't help but say, "Mr. Gao, this is quite difficult. It's almost like developing the material of tempered glass from scratch. If we can do it, the cost may be a bit high."

Gao Huaijun waved his hand impatiently, "Don't be afraid of the price! Don't think about current mobile phones with the original framework."

"Think about it, your products are not substantially different from those of other manufacturers. Why would customers buy your products?"

The executives present were stunned at first, and then nodded in unison.

Gao Huaijun has been leading the R&D direction of Hillhouse since mate1.

It can be said that no one in China knows more about mobile phone research and development and manufacturing than him.

Today's mobile phone products have not seen any significant changes for many years. Apart from changes in the series codes of the phones, it is difficult to tell what has changed in a particular phone.

The lack of substantial product changes is also the core reason why it is increasingly difficult for customers to consider upgrading their mobile phones.

If you can't, then I'll just use it!
The Chinese are not rich yet, so it is normal for them to patch up their things for another three years.

Gao Huaijun's method of subverting the public's consciousness by starting from a point that everyone generally believes will not lead to a breakthrough is actually an important means of increasing product premium.

However, ordinary product development engineers cannot be as imaginative as Gao Huaijun.

Originally, all the executives present felt that no matter how great Gao Huaijun was, he would not be able to come up with any amazing products.

But that's not necessarily the case now.

Now it seems that Gao Huaijun is really awesome!

“The second application for product differentiation is that I hope the antenna will be miniaturized to receive satellite signals!”

"This function is the homework I assigned to President Min two years ago. Have you finished it?"

As he spoke, Gao Huaijun looked at Min Weiguo standing aside.

Min Weiguo smiled and said, "This technology is a bit difficult now because it involves communication-related fields."

"We set up a special project team two years ago to miniaturize the antenna so that it can receive satellite signals, and we have made some progress now."

After saying this, he felt a little proud.

Others need a large external antenna to stably receive satellite signals, but Hillhouse is also related to the communications field and has been immersed in it for so many years that it can directly build it in to receive satellite signals stably.

It’s pretty awesome!
In China, the only competitor stronger than Hillhouse in the field of mobile communications is China Telecom.

The executives present, especially those who were unfamiliar with this technology, were all shocked.

There was an expression of disbelief on their faces.

They knew about satellite phones.

On ocean liners.

But those things are usually bigger.

The antenna needs to be built-in, especially an antenna like Hillhouse's.

Not easy!

The difficulty of this function is to realize the communication between the handheld terminal and the satellite so that the two can have data connection. If the mobile phone antenna is too small and not strong enough, then this function is likely to become useless.

Typically, even with a large satellite phone, moving a few feet in one direction or the other can help or hinder a call.

If there's a mountain or a large building blocking the signal's path, you'll need to move.

For areas with weak satellite signals, there is basically nothing we can do.

In this respect, it is very similar to the big pot lid of the 90s.

At that time, the telephone was sometimes out of sight, so you had to flip the big pot lid over and over to find a signal.

This is also unavoidable in order to watch TV.

When you are in an emergency, the satellite phone is not working and the connection is intermittent.

If it were tested by someone with bad intentions, it would be really embarrassing.

"Are you sure you want to put this thing on your phone?"

"If the built-in RF chip has insufficient power, a major bug will occur."

Liang Mengsong on the side couldn't help but reply.

He is a real person who works seriously and will not fool around.

If this thing really just follows the boss' lead, something terrible will happen!
If this thing is really that easy to do, why don't other companies, especially Zhongwei, which are all good at communication engineering, do it?

"The specific content of this solution is to use the integrated conductive frame of the mobile phone and the built-in multi-satellite antenna to achieve signal enhancement and direct connection to the satellite."

"The telecommunications company and we have jointly researched and developed six routes, covering areas that are most difficult for domestic satellite networks to cover. It is expected to cover places such as Lop Nur, Qiangtang, Mohe, Yushu, and Meili Snow Mountain, with a total distance of more than 6 kilometers."

"Based on the above, we only need to design and manufacture satellite baseband chips to realize this function."

"There is no doubt that you, Mr. Liang, are the best choice."

Li Zongli, who was standing by, smiled and supplemented Liang Mengsong's question.

After hearing this, the executives present couldn't help but look at Li Zonglin in shock.

So the current situation is that this thing seems to be very simple and can be summarized in just a few words.

In fact, if Hillhouse does not do it, it will be a difficult problem for the whole world.

The difficulty lies not in the implementation of a single point technology, but in how to integrate a unified full-link satellite call solution.

How could something like this be developed?
The key is...

It’s time to land!
To complete this chip, we need an all-round king in the fields of communications, chip design, chip manufacturing, and mobile phones to accomplish this.

Looking around the world, there are only Zhongwei and Hillhouse.

Even China has its shortcomings.

In the field of chip manufacturing, it is two levels weaker than Hillhouse.

Although Hillhouse is at the same level as other companies in the communications field, it has its own communications research institute and is rapidly catching up with its shortcomings in this area.

Sansang and Qualcomm have shortcomings in the communications field, Pingguo cannot even produce 5G baseband. Musk's SpaceX has Starlink, but it is a layman in civil satellite communications and chip design and manufacturing.

so. . .

Now, who else but Hillhouse Capital can do it?
