Li Mo found that he and Lao Chen had misunderstood each other's meaning, but this was definitely not the place to talk, and Li Mo didn't want to talk to Lao Chen about the following things in everyone's puzzled eyes. Pen, fun, pavilion www. biquge。 info

"Headmaster, we said in our room, aunt, there is no privacy in your room, right?" Li Mo said as he left to walk into the room.

Lao Chen was speechless and said to a few guests: "You see, how lazy my student must be. ”

Several guests laughed together, but faintly, they all felt that Li Mo's identity might not be as simple as a student.

When he arrived at the room, Li Mo whispered: "Principal, now the industry in my hands is mainly toys and clothing. ”

"I know."

"Next is the game industry, which has already begun, and will soon build a branch in Modu."

"The gaming industry?"

"It's the kind of handheld computer that Western countries have on the TV, and the related game cards."

"And daily chemical products?"

"That may be the year after tomorrow, and at the same time, I may also enter the beverage, food, supermarket, furniture, logistics industry, this is Yi Group's future plan, but these are low-tech goods."

"Daily chemicals are not low-tech."

"That's just a medium-tech commodity, but from this summer onwards, I'm going to prepare for another high-tech commodity, a mobile phone...... There may also be pagers, as well as PCs, and if successful, then move on to home appliances and small appliances. ”

The pager is a sunset industry, it can be better to develop and develop, and it is not possible to develop and pull down, mainly depending on the patent negotiation with Motorola, if the patent barriers cannot be avoided, or the cost is too high, Li Mo intends to give up directly. But there is one thing, there must be no piracy in his hands, otherwise it will be a stone to shoot himself in the foot, and it will also ruin the reputation and brand of the future company.

While developing the mobile phone industry, along with it, the technology of various components was improved, and its own patents were registered, which gradually entered the PC industry, home appliance industry and small household appliance industry.

"You ......" Lao Chen was stunned.

"Headmaster, this is a plan, and nothing that comes out of my hands is bad, and excellence is a beautiful spirit, but it means that you have to put in more effort. Especially mobile phones and PCs ......"

"Is it just a PC?"

"There are three kinds of computers at the moment, one is a super-large computer, which I won't touch, because it may be related to the military, and my identity is an eyesore. The second type is the enterprise machine, medium and large computers, but with the advancement of technology, this kind of enterprise machine has become polarized, one has become a mini version of the large computer, and the other has become a business PC, so I will not touch this one. Even if the company in my hands needs an enterprise machine, on which the Western countries are not strictly blocked, they can be purchased at any time. Therefore, I will only enter the PC, and I am talking about the most important part of the mobile phone and the PC. ”

But whether it is a mobile phone or a PC, the most important part is the CPU, which is called the central processing unit in Chinese.

FOLLOWED BY MEMORY, WHICH IS DIVIDED INTO RANDOM ACCESS MEMORY (RAM), READ-ONLY MEMORY (ROM), AND CACHE.

Then there are graphics cards, GPUs, also known as graphics processors.

Hard disk, computer hard disk is HD, server hard disk is ETY, and it is commonly used to say C disk and D disk on the computer......

The motherboard, which is the most untechnical, is also the first gap to break through in China.

There are a lot of components that are chip-related, especially the CPU, so to speak, which is a chipset in its own right.

Because Lao Chen is good at chemical engineering, he doesn't know much about this knowledge, so Li Mo talked about its process again.

The first step is to extract silicon and purify it. Silicon is selected because of its wide source of raw materials, and it is located at the junction of the metal element region and the non-metallic element region in the periodic table, so it has the properties of semiconductors, suitable for the manufacture of various tiny transistors, and is currently one of the most suitable materials for the manufacture of modern large-scale integrated circuits.

Therefore, some people also say that it is a semiconductor industry, but it cannot represent semiconductors, and semiconductors involve more industries.

During the silicon purification process, the raw silicon is melted and placed into a huge quartz furnace. At this point, a seed is placed in the furnace so that the silicon crystal grows around the seed until a near-perfect monocrystalline silicon is formed. The larger the diameter, the better, but the larger the diameter, the more technically difficult.

The next step is to cut the wafer, which is shaped into a perfect cylinder and then cut with high-precision equipment. Generally speaking, the thinner the wafer is cut, the more finished CPUs can be made with the same amount of silicon material.

Of course, it's easy to say, and the atomic bomb seems to be very simple, and the principle has been explained in high school physics......

Then to the lithography machine etching, a photoresist substance is coated on the silicon oxide layer obtained by heat treatment, and the ultraviolet rays irradiate the silicon substrate through a template printed with the complex circuit structure pattern of the CPU, and the photoresist substance is dissolved in the place irradiated by the ultraviolet rays. In order to avoid the interference of light in areas that do not need to be exposed, masks must be made to mask these areas. It's quite a complex process, and the complexity of each mask has to be described in 10GB of data.

Next, the light is stopped and the mask is removed, and a specific chemical solution is used to wash off the exposed photoresist film and the layer of silicon that adheres to the resist film underneath. The exposed silicon will then be bombarded with atoms, causing the exposed silicon substrate to be locally doped, thus changing the conductive state of these regions to create an N or P well, which, combined with the substrate fabricated above, completes the gate circuit of the CPU.

Then there is repeated layering, which must be applied multiple times with photoresist, repeated photocopying and etching processes to obtain a trench structure containing polysilicon and silicon oxides, and finally form a 3D structure, which is the core of the final CPU. At the same time, the middle of each layer should be filled with metal as a conductor......

The CPU is a wafer that cannot be used directly by the user and must be encapsulated in a ceramic or plastic enclosure so that it can be easily mounted on a circuit board. The packaging structure is different, but the more advanced the CPU package, the more complex it is, and the new package can often bring about the improvement of the electrical performance and stability of the chip, and can indirectly provide a solid and reliable foundation for the improvement of the main frequency.

Finally, there are many tests, and even the accounting of each CIP must be tested repeatedly to confirm that there are no problems before leaving the factory.

The so-called wafer is to take out the silicon rod in the furnace, and then cut it, tumble, slice, chamfer, polish, laser engrave, and package, which is the wafer.

It is the raw material for making chips, and if you want to make chips, you have to slowly dig out non-destructive materials from the wafer, and then go through more complex processing to become a chip.

So later, Western countries relaxed the foundry of wafers to China, and the chip foundry has not been relaxed, and even high-end lithography machines are banned from being exported to China, where can chips be produced? So China obediently spends more than $200 billion a year to buy all kinds of chips, more than any commodity such as oil, and also more than all military spending, as well as the legendary Loongson......

Li Mo does not necessarily have to produce CPUs domestically.

He has already set his sights on Qualcomm, which at this time is not the later Qualcomm, take it...... Li Mo has never been stingy when he acquires or buys shares, and as long as he can afford the price, it is not too difficult to take Qualcomm down.

Spend some more money to buy related patented technologies, for example, if Intel has no accidents, it will launch the 486 processor next year, 286 will definitely be eliminated, and 386 can also be taken down as long as it reaches a certain price.

This is the CPU of the mobile phone, can the mobile phone be on the 486 processor now? Don't swallow it.

Its requirement is not that the structure is complex, but that the structure is miniaturized, of course, it is not easy, but it is burned with money. If the acquisition of Qualcomm is successful, it will be the focus of Qualcomm's research and development.

As well as some other important components of mobile phones, they must form their own core technology, and they can also register patents.

Don't underestimate these patents, even if Nokia later collapsed in the mobile phone industry, it also collected a lot of related patent fees a year, if you don't give it, can it be done?

With its own core technology, it becomes easy to find a foundry for processing.

Once you enter the PC, you can continue to use Intel's processors, but with the feedback of mobile phones, Qualcomm will also have more R&D funds, and it will also be quick to catch up.

But Li Mo always felt uneasy.

Even if Qualcomm is won, Qualcomm is just a Fabless. Enterprises that integrate multiple industrial chain links such as chip design, manufacturing, packaging and testing, and some even have their own downstream machine links, such as Intel, Samsung, IBM, and such chip suppliers are called IDMs.

There is also a category that has designed, developed, promoted and sold chips, and outsourcing production-related business to professional manufacturers, such as Broadcom, MediaTek, Spreadtrum, including Qualcomm, etc., but does not have its own chip processing plant chip suppliers called Fabless.

What's more, this kind of technology products also have a close relationship with the military.

It's easy to get strangled by someone.

Don't ask why? Don't underestimate the protectionism of the United States, let alone Motorola's influence in the United States.

Immigrants, immigrants or Chinese! Even because of a generation of immigrants, it was not good for the United States to arrest Li Mo for espionage and lock him up for two years.

Li Mo thought at home, thought of the three holes of the cunning rabbit, and thought of a safe "backup port", which is extremely important because it is related to many technologies, including optical mirrors.

I still don't think it's safe.

So I thought about it and thought that it was still produced in China.

There are several advantages, one is that the current technical content is not too high, and it is much easier to catch up now than to catch up in the future, which is very important.

Second, the United States also knows the importance of chips, but no one can really see its future big market, the precautions are not so strict, there is an example, in 87 years, China wants to improve more than 200 J-8II fighters, so it signed a contract with the Grumman company of the United States imperialism, according to the contract, these 200 aircraft will be installed with American-made radar and fire control system, at that time Sino-US relations were good, but just 2 years later, China has delivered 2 J-8II test fighters to the United States, but the US government unilaterally terminated the contract, 2 fighter jets were also seized for 4 years before they were returned to China.

Why you regret it next year, you can understand.

That incident happened, which made many Americans think that China rejects people's cooking, and that China did export "isms" to the outside world in the 50s and 60s.

As a result, the anti-China faction gradually gained the upper hand, and even the elder Bush, who was only the president, not the king, had to compromise, but it was not yet called a serious hostile relationship.

Since Clinton, the collapse of the Soviet Union, and the United States looking for imaginary enemies all over the world, President Ye Da is pro-Western, and it is enough to take precautions, and China has become the best enemy of the United States. But Li Mo still has a few years of buffer time.

The third is that Bush Sr. is not too bad to China, and besides, the shares of the two companies after Bush Jr. have become more and more valuable, and the Soviet Union has not disintegrated......

This year, in particular, the situation is even better.

Li Mo can first invite a number of experts to come over, put them in Qualcomm, eat the approximate technology, or even directly introduce its technology to China, and then burn money frantically, before the more notorious "Wassenaar Agreement" in 96 came out, the two phases of technology are not much different, and then the Western world can only look at the ocean and sigh.

Fourth, various companies are burning money one after another, but some companies have begun to make money one after another, for example, this year, Rong Deke will get a lot of profits, next year Yile will also make a profit, and even Yibao can also make a profit.

What is this money for? Is it worth spending, can it be spent?

Although chip manufacturing involves various industries, Li Mo also has enough capital to burn out various industries.

It is not exactly burning, and in the process of burning, some low-end machines or products processed have a certain market at home or abroad.

Lao Chen is engaged in chemical engineering, Li Mo was afraid that Lao Chen would not understand, so he explained carefully, and there were some things, but Li Mo did not say it.

After speaking, he said: "Principal, don't underestimate this lithography machine, if you can make a high-end lithography machine, then it will not be too difficult for both wafers and chips." Although they belong to different fields, they are all the world's most advanced scientific and technological fields. ”

"Isn't that lithography machine in the Institute of Optoelectronics good?"

"Optoelectronics?"

"I don't know much about this field, but I've heard that in 81, the Institute of Optoelectronics developed China's first lithography machine, and won the first prize of scientific and technological progress of the Chinese Academy of Sciences in 83."

"Oh......" Li Mo perked up.

He doesn't know what the lithography machine of the Institute of Optoelectronics looks like, and it is estimated that most of them still can't use it to produce chips, at least high-end chips. But with it, it means that there is a certain foundation. Just like a child reads, you can start with elementary school before you can go to middle school. It is impossible to go to junior high school without going to primary school, does China now have such a developed scientific and technological environment?

"Li Mo, there are ...... Let me ask you, in the 70s, there was also some semiconductor industry in China, and even now, various research institutes continue to develop semiconductors. Of course, that kind of environment also forced the state to tighten its belts and continue to engage in some important scientific research. ”

Speaking of this, Lao Chen sighed.

In the 50s and early 60s, despite the difficulties of the country, many scientific research achievements were achieved. However, after ten years of tossing, scientists have been mostly regarded as cows, ghosts, snakes, and gods, and most scientific research has come to a halt. This stop, the gap is getting bigger and bigger.

However, the CPU has nothing to do with that decade, Lao Chen continued: "In the 70s, the country also had some CPU technology. However, after the reform and opening up, various reasons, including the small domestic computer market, did not have a large rate of return. The cost of research and development is high, the country is poor, and there is not much money allocated. And foreign countries have also resumed exports to China, including some smuggling impacts, it seems that in the past two years, I have not heard of any research institutes continuing to develop CUP, and there may be almost no units that develop chips. ”

With this stop, the gap is getting wider and wider.

Not only technology, but also a patent barrier is the key, and later, I can't get around it.

Of course, you can't blame the country, who can know what will happen later? The second is that the state really has no money in its hands.

"Can you find any of the original experts?"

"You should be able to find them, but these experts are not idle, most of them have turned to R&D in other industries, you know, there is a shortage of talent in all aspects of the country."

Li Mo smiled bitterly, well, even talents have to be cultivated by themselves!

And how many opponents will he have in the future? Tiger Fund, Motorola is just an appetizer.

Li Mo asked again: "Principal, do you know Secretary Wen's phone number?" ”

"Li Mo, I think the path you have chosen is unlikely to succeed, even if you find Secretary Wen, he has no choice," Lao Chen persuaded him.

Li Mo also said just now that I spend money to buy patents, buy technology, and even buy companies that produce chips in the United States, and pay taxes in the United States under the banner of American companies, which may be realized.

It's not easy to move to China, for example, wafers, the first thing to ship is silica, which is sand, and there are a lot of these things. Then it is refined in an electric arc furnace and chlorinated with hydrochloric acid to obtain high-purity polysilicon. It is then melted in a furnace and the monocrystalline silicon rod is pulled out with the seed seed.

Just this process, Lao Chen faintly felt that it would cost countless funds...... He guessed right, in 10 years, it will cost $1.5 billion to build a manufacturing plant capable of producing 200 mm diameter silicon ingots, and about $3.5 billion to build a manufacturing plant to produce 300 mm diameter silicon ingots! It is impossible to need so much money now, but after this series of technologies are developed and then produced, Li Mo can't figure out how much money it will cost.

And it requires a variety of advanced equipment, not only lithography machines, etching machines, but also a variety of advanced electronic or mechanical equipment, instrumentation.

Either they are imported, and some are not sold to China at all.

If you want to produce for a long time, it is definitely not a way to secretly get one or two units, and Li Mo's industry is mostly in foreign countries, once it is discovered, it is easy to punish.

Self-research and development, so much equipment, how much money do you have to burn out?

Even if the equipment is made, there is still technology next, even if the technology is a family, it has been obtained, and then there is the process. Whether the process can be learned comprehensively, and there is still a talent level.

In Lao Chen's eyes, they are the country's science and technology.

Li Mo knows better, the key is not to develop now, and the gap will become bigger and bigger in the future, such as wafer cutting, which will evolve into a laser slicer in a few years, and then catch up when the time comes, it really takes the strength of a country to catch up.

It may be successful, it may be semi-successful, that is, it is still not possible to produce high-quality related chip products in China, but with countless money burning, many other technologies can be developed, or low-end chip products can be produced, and it can be improvised. The other is a bad ending, maybe hundreds of millions of dollars, or even billions of dollars, all in vain.

But Li Mo didn't look for Secretary Wen for this.

Headache to headache, let's give Samsung some eye drops first.
