Slicing is a colloquial name that is a method of copycat chips.

To put it simply, it is to take back the chips that can be bought on the market, remove the outer package, expose the circuit board inside, and then put it under the microscope to observe the internal structure of the chip, draw it little by little, without knowing the internal logic control, regional structure, draw it all, and then use its own chip production equipment to process the exact same chip, so that it will come out.

This is not a secret, in the past few years, the chipping has been used by many units, Intel's 8080 chip, it was given to the cottage by the fifth factory of the magic element, the number 5G8080, this 5G is the meaning of the fifth factory.

Lao Maozi also did this, and surveying and mapping imitated the 8086 chip.

But in later generations, no one has done this, those copycat processors are just polishing off the original number, and then replacing them with better performance numbers, processors can only be produced by two manufacturers, and the others have no ability.

So why not continue with the slicing way?

On the one hand, because of the huge number of internal transistors, 8080 only has more than 5,000 MOS transistors, and in later generations, the processor is often hundreds of millions, tens of billions, hundreds of billions of transistors, even if you use an electron tunneling microscope to see the structure of the processor, if you want to completely copy it, it will take a long time and energy.

Even if it is copied, it has to be able to produce it yourself, and the advanced process of more than ten nanometers or even a few nanometers used by processors in later generations is not something that ordinary electronics factories can make.

But now, in the eighties and nineties, you can still catch up.

Hearing Qin Feng's way of slicing, everyone's eyes lit up at first, and then dimmed: "Mr. Qin, this is not so easy, the chip technology in the United States is developing rapidly, and the APG-66 radar is no longer an ordinary general-purpose processor, but a special digital signal processor, that is, DSP, This chip is manufactured using a 1.5 micron process, and the highest production process in our country is only 5 microns, so it is impossible to manufacture this advanced chip, if we use our process, it will not only increase the area, but also increase heat and power consumption, especially heat, overheating will make it unable to work normally......"

Before he finished speaking, everyone saw that Qin Feng had already stood up and walked to the telephone in the corner of the conference room.

What did Mr. Qin do?

In the eyes of everyone, Qin Feng picked up the telephone and dialed a number.

"Hey, is our chip production line installed? What, it will take three or five days to debug? Okay, it's okay, you guys keep busy, I'm just asking. ”

Putting down the phone, Qin Feng looked at everyone: "Everyone, our high-tech base of Pacific Group has installed a 1-micron chip production line. It will be ready to go in no time. ”

"What, a micron?" The crowd was shocked again.

When did the Pacific Group play with chips? And, where are these devices imported from?

"Mr. Qin, which company do you work with?"

"Yes, Mr. Qin, this huge procurement plan is actually promoted by your private enterprises, amazing, really amazing."

"No, we don't cooperate with foreign countries, the entire production line, all the equipment is our own." Qin Feng said: "We in the East have advanced chip production equipment research and development capabilities, but some people dare not use it, they dare not use it, we will use it!" I just want to ask the military if they dare to use the chips of our private enterprises. ”

"If you can make it, we can use it." Lin Lao said.

If you don't believe in others, can you still believe in Mr. Qin? As long as Mr. Qin says yes, then it will definitely do!

Qin Feng smiled: "Okay, then let's let others see how powerful our Dongfang technology and industry are!" First surveyed and mapped the imitation AWG-9 radar, and then transplanted the post-circuit of the American-made AGP-66 radar, so that this radar not only has a powerful long-range search capability, but also has a strong post-data processing capability, becoming the world's most advanced airborne radar for heavy fighters! ”

The APG-66 radar circuit is advanced, the AWG-9 radar has a long search range, and the performance of the two is combined, which is the most powerful airborne radar in this era!

Everyone's hearts were on fire.

"That's right, we're going to build the most advanced airborne radar!"

"Ahem, but let's just produce, and you 14 have to do it."

Although Qin Feng also has a chip R&D team led by Ni Lao, they are engaged in positive R&D, and they mainly focus on general-purpose processors, so they simply do not have the ability to engage in this kind of specialized airborne radar chip.

After all, the quantity of this chip is too small, and relying on those orders from the army is to earn a processing fee, and R&D investment has to be wasted.

"No problem, when we get the radar prototype of APG-66, let's study the circuit, disassemble the chip, and thoroughly grasp the principle of this advanced radar, by the way, Mr. Qin, can we go to your production line to have a look?"

This is the first 1-micron chip production line in the country! In the country's 531 strategy, only 5 microns have been realized, 3 microns are being pursued, and 1 micron is still in the imagination, but I didn't expect it to be realized here in the East!

The Pacific Group is too strong!

"Okay, after the meeting, after eating, I'll take you to visit!"

Lin Lao smiled: "Okay, lunch will be eaten here with us, two braised beef noodles per person!" ”

Qin Feng glanced at Lin Lao, picking, really picking the door, how can instant noodles, an emergency food, be used to entertain people? You're just as slamming the door as a sunspot!

However, when they heard Lin Lao say instant noodles, everyone below became excited.

"Okay, I haven't eaten instant noodles in a long time."

"That's right, prices have been rising in the past few months, and I can't afford it!"

"Can you come with three packs?"

Well, since the big guy wants to eat, what else does Qin Feng have to say.

"After visiting the chip factory, I will give each of the big guys a box of instant noodles."

"Long live Mr. Qin!"

"Ahem, who shouted? Tell you, yours is gone! ”

The high-tech R&D base of Pacific Group is located in the urban area, with a beautiful environment and a large space, and each project has its own independent place, and the chip production plant is no exception.

The other institutions are all using the original buildings, and the factory building of the chip production plant is also the original, but the green bricks on the outside have all been covered with cement, and the outside of the cement has been painted, and all the original wooden windows have been replaced with steel windows, which looks brand new.

It's just a change on the outside, and when you enter the gate, everyone's eyes are going to fall out in surprise!

Inside, aluminum alloy was used as a frame, and double-glazed glass was used as a barrier to build a room-within-a-room!

This has not yet entered the nineties, aluminum alloy is very tall, use it to build a glass house, you can imagine how moated it is!

"The chip production workshop needs to have a high level of cleanliness, so we deliberately made this design." Ni Lao stood at the door with a smile and introduced to everyone, although he is mainly responsible for the research and development of chips, but the entire high-tech base is in charge of him, I haven't seen Qin Feng for a few months, and I am very happy to see it this time, not to mention that there are so many guests.

"Do you have to change your shoes when you enter the door?" Lin Lao spoke.

"Not only do you have to change your shoes, you have to wear a coat all over your body, and you have to be purified in a transition workshop." Ni Lao said.

"Lin Lao, don't go into this kind of place." Qin Feng heard the dissatisfaction in Lin Lao's tone, and said, "You are not suitable for this kind of place. ”

Lin Lao really planned to complain a few words, but as soon as Qin Feng said this, Lin Lao glanced at him: "Stirring up the law, right?" I'm not fooled, Lao Ni, just do what you have to do, our Lao Lin is not special. ”

A few minutes later, everyone wearing white coats passed through the transition workshop, cleaned their bodies, and entered the dust-free workshop inside.

The manufacturing process of the chip has reached 1 micron, and even if a piece of dust falls on the chip, it may cause a short circuit inside the chip, so the chip workshop has the highest requirements for cleanliness.

Double-storey rooms, air conditioning purification and filtration systems are available, and the internal space is clean and tidy, not to mention a single hair or dust.

"We visited from the starting line, and the first machine we saw was a monocrystalline furnace, which is responsible for smelting polysilicon into monocrystalline silicon, pulling out silicon rods, and then slicing, this set of equipment is developed by our 48th domestic institute."

Although chips are made of sand, advanced chip factories generally do not start smelting from sand, and there are special companies responsible for sand to coarse silicon, and chip factories only need to melt polysilicon and pull single crystals to manufacture silicon rods.

This kind of monocrystalline furnace is also very distinctive, the bottom is a thick cylindrical structure, the top is a thin cylinder, the single-crystal silicon drawn out from the top, the inner diameter of the cylinder above, is the diameter of the wafer, look at the appearance of this kind of machine, it should be the most common 6-inch silicon rod.

There are four furnaces in total, lined up, like four large boilers, and it looks spectacular.

"The 48th Institute is our main domestic semiconductor equipment supply unit, and they have been building single crystal furnaces before, but they are not so large." Ben Lao looked at the single crystal furnace, his eyes were full of emotion: "When we want to update the equipment, we will also get one from them!" ”

"Here are slicers and polishing machines, these machines and equipment are all developed by our domestic 45 institutes." Mr. Ni continued: "They originally only had the equipment to cut three-inch silicon rods, but after receiving our order, they invested all the technical backbone to engage in research and development, and finally developed it for us on time." Coupled with R&D expenses, it is also cheaper than purchasing from abroad. ”

When the silicon rod is pulled out, it is sliced into wafers, and then polished in preparation for etching circuits on it.

Next is the low-pressure chemical vapor deposition and plasma-enhanced chemical vapor deposition devices, after which the wafer surface is covered with thin film material and waits for the next step of etching, these devices are jointly developed by the Capital Instrument Factory and several universities in the capital.

The wafer has gone through these steps, is ready, and is ready to be loaded onto the lithography machine.

Although other equipment is also high-tech, in terms of scientific and technological content, it is not as good as the lithography machine, which is the key to chip manufacturing.

Two large lithography machines were placed in the center of the workshop, Professor Xu and several technicians were busy on it, and Qin Feng and others still did not stop their work when they came over.

"Professor Xu, someone is coming to visit, can you tell the big guy?" Ni Lao spoke.

"I want to see for myself, I don't have time!" Professor Xu didn't even raise his head.

"Okay, he has a character, which is bigger than our old Lin's temper." Lin Lao sighed on the side: "But to suit our old Lin's appetite, if a leader comes to visit, he will come out to greet him, the kind of person who must be incapable." ”

Hearing Lin Lao say this, Professor Xu raised his head and glanced at Lin Lao: "You can say this kind of thing, you can be regarded as an informed leader, hmph, there are always people who want to visit recently, we are a chip production plant, not a tourist attraction, Lao Ni, I didn't say you, people who shouldn't be brought, don't bring them in, affect our work." ”

Don't look at Ni Lao is the person in charge here, Professor Xu has never been a bird to him, you are honestly responsible for designing the chip, I am responsible for the production of this chip, don't always interfere indiscriminately!

Ni Lao was very embarrassed.

Qin Feng smiled: "Yes, Ni Lao, you can't bring in irrelevant people, if there are any leaders who want to visit in the future, it's inconvenient for you to shirk, just leave it to me, without my consent, they can't visit." ”

"Mr. Qin, it's not good for you not to give those leaders face."

"They have to be able to find me first......"

At this time, Professor Xu lowered his head again to do things, and when he heard that Ni Lao was called Mr. Qin, Professor Xu quickly took off his reading glasses and looked at Qin Feng: "Mr. Qin, are you Mr. Qin?" ”

After Professor Xu finished speaking, he quickly stood up and stretched out his hand enthusiastically: "Mr. Qin, welcome, come and visit us, why don't you say hello in advance, I'll introduce you." ”

Entering the chip workshop, everyone is dressed the same: a coat, from head to toe, and a mask, everyone is the same, acquaintances can be identified by their eyes and figure, if they are not very familiar, it is really inconvenient to recognize them directly.

Lin Lao sighed on the side, his face is not as good as Mr. Qin's!

"Well, Professor Xu, you should be busy first, I remember, our lithography machine has been able to stably produce chips with 1 micron process, what are you still messing with?"

"Lao Ni's team has not yet completed the design of the chip, and the production line on our side has been built, so we plan to continue to improve it and increase the process to 0.8 microns."

0.8 microns!

Everyone was shocked, now, 1 micron is already the world's highest level, and the more advanced 0.8 micron process is still in the laboratory, but I didn't expect that here in the Pacific Group, it has reached the world-class level!

That's amazing!

Qin Feng also sighed that if there was money to engage in chips in the 80s, future generations would definitely not lag behind! The R&D capabilities of chip equipment in our era are not bad, but there is no money!

The 486 process that will be launched next year is still a 1-micron process, and the Pentium processor has only evolved to 0.8 microns after entering the 90s, and we have begun to prepare for mass production of 0.8 micron processes!

One step behind, one step behind, as long as we can lead the world now, we can always be in the lead!

"Okay, if it is raised to 0.8 microns, then we will have a world-class chip production plant, so that those who only know how to buy and buy in China can see whether it is more important for foreign monks to chant scriptures or self-reliance!"

"That's right, Mr. Qin, we just can't swallow this breath! We can obviously develop advanced equipment ourselves, but no one uses it! In their eyes, foreign obsolete equipment is fragrant! ”

Speaking of this, Professor Xu clenched his fists.

"Mr. Qin, I don't know how the news has been revealed, there are always some people who want to visit, and many of them are foreign colleagues." Ni Lao said: "It's not a way for us to stop them, you say, should we just invite them to visit and let them know the advanced nature of our oriental technology?" ”

Qin Feng shook his head: "Of course not!" ”

"Why?"

"It's too advanced to be displayed." Qin Feng said: "If they want to come, they will definitely ask this and that, we are not obliged to answer them, and if they learn and catch up with us, what will we do?" ”

Elder Ni nodded, of course he knew that Qin Feng was not in favor of going public from the beginning.

But then in this way, we are unknown?

"To what extent has our Loongson been developed?" Qin Feng asked about this project.

"Mr. Qin, according to your requirements, we are starting from scratch, independent research and development, and have completed the development of the architecture and instruction set, and carried out detailed development, which is expected to be officially taped out until next year."

This progress is already very fast, after all, this is something that has never been done before!

After the computing institute cut off the VLSI project, a group of people represented by Huang Lao were holding back their strength, and after the Pacific Group's capital investment, they worked hard day and night.

The architecture is there, the instruction set is there, and the next step is detailed development, and then tape-out!

In later generations, the research and development of Loongson No. 1 is also like this, in May 01, the project was established, and the research and development funds of 1 million were obtained, and it was officially listed on September 28, 02, and it only took more than a year to achieve a breakthrough of zero.

Although Loongson's road is very difficult because of ecological problems, this is a zero breakthrough after all.

Now, it also takes a year, and it still uses an independent instruction set, but the integration of transistors in this era is low, so the difficulty of the two is about the same.

"After tape-out next year, the outside world will naturally know that we are using the most advanced 0.8 micron process, and our Loongson can also use advanced technology to improve performance, the best of both worlds. Qin Feng made arrangements: "As for the outside world wanting to visit, there is no way!" However, if they have a demand, send us the circuit diagram and we can help with the production. ”

Jingle bells!

At this time, the phone inside the factory rang, Ni Lao picked up the phone, and a familiar voice came from inside: "Old Ni, some experts from island countries have heard about the project of your high-tech R&D base and want to visit ......."
