Chapter 94 Atomic Imprinter

The current chip technology is simple, it is very simple, that is, silicon wafers are carved with lines, conductive impurities are injected to form switches.

It is complicated, and it is very complicated. If it is at the centimeter level, the texture engraving and conductive impurity injection are fine, but at the nanometer level, these processes are very troublesome to complete.

But Huang Haojie saw another processing method from the handling ability of C31 fullerene.

That's right, it is to directly use the handling capacity of C31 to engrave lines on silicon wafers, inject conductive impurities, and plate copper. All these processes can be completed by C31.

But the premise is that Huang Haojie completes the precise control of C31 fullerene.

Semiconductor Research Institute, in the micro-etching laboratory.

A dozen researchers and engineers are debugging a huge instrument.

Atom imprinter made by the Semiconductor Research Institute.

Zheng Xinwang is a semiconductor graduate student who just graduated this year. He never thought that he would come to Yinhe Technology to work.

Originally he wanted to study for a Ph.D., but there was an unexpected situation. The doctoral supervisor he applied for just happened to have an accident, and Zheng Xinwang happened to meet Yinhe Technology who was recruiting, so he came to Yinhe Technology to work.

After coming to Galaxy Technology, Zheng Xinwang discovered that the semiconductor technology that Galaxy Technology is researching has subverted all current chip manufacturing processes.

He is carefully manipulating the carbon nanofabrication needle through an electron microscope and computer, engraving on the silicon wafer.

In order to make this carbon nano needle, it took them half a month to complete this five-nanometer carbon nano needle.

Input the circuit diagram of the chip into the computer, and then calculate it through the computer and cooperate with the electron microscope.

The carbon nanoneedle is on the silicon wafer, and quickly carves out circuit grooves. The principle is very simple. Under the stimulation of specific conditions, the C31 of the carbon nanoneedle combines with the silicon atoms on the silicon wafer, and then the silicon atoms are separated from the silicon out of the sheet so that a groove is formed.

Numerous grooves are connected together to form a groove circuit.

"Xin Wang, how is it?" A middle-aged man with gray hair came over and asked.

"Mr. Zhao, I'm adjusting some data. The five-nanometer level is too small, and about 43% of the circuit engraving is inaccurate." Zheng Xinwang said helplessly.

Zhao Gong didn't show any disappointed expression.

"Everything is difficult at the beginning, keep working hard, I'll go and have a look."

Of course Zheng Xinwang knew that there was no rush for such a thing, because once the first circuit chip was engraved.

Then it will be very easy to handle.

On the other hand, Star Map Company also took a lot of money and directly merged three semiconductor design companies in Dongtang.

The domestic chip manufacturing industry is not good, but the chip design industry is still so-so, such as Huawei's HiSilicon Semiconductor, which is a top semiconductor design company.

Huang Haojie, who had no time to linger, directly asked Wang Bosi to launch a silver offensive, using the method of mergers to promote the chip design capabilities of Xingtu Company.

Du Wei and the others, together with the chip designers obtained from three semiconductor design companies, and a large number of 30-90 nanometer chip patents purchased by Zhang Rujing, started the independent design plan.

Although these chip patents have been eliminated by others, it does not mean that they are all rubbish. After all, chip design has many things in common.

For example, a 5-nanometer chip design can be used in a 50-nanometer chip, and the same is true for a 50-nanometer chip design on a 5-nanometer chip.

Doing so may lead to a regression in chip performance and original design, but the key lies not in chip design, but in chip manufacturing.

After all, so what if you can design a 1-nanometer chip. Without the ability to manufacture a 1-nanometer chip, everything is a spectacle.

Just like Huawei's chips, your HiSilicon semiconductor design capabilities are very powerful, but the problem is that you don't have chip manufacturing capabilities.

Once Taijidian has some wax gourd tofu, Huawei will experience a shortage of chips or cut off the supply. This is not to end the calf.

The same is true for Sino-Singapore Communications. In 2016, it was disgraced by Milijia. The billions of fines were equivalent to two years of Sino-Singapore Communications’ profits, so it was nothing.

Huang Haojie would rather study slowly by himself, and would not easily hand over the production of core components to Crooked Nuts.

Sanxin Company likes to do this kind of thing the most, whether it is the mobile phone screen or memory.

DRAM, or dynamic random access memory, is our most common system memory.

Whether it is a mobile phone, a computer or any smart device, the memory (such as a memory stick) is composed of single or multiple DRAM particles.

According to the data in 2016, the global DRAM market size is about US$410 billion, of which Sanxin, SK Hynix, and Micron have shown a three-point posture. The three companies account for more than 95% of the market share, and the industry has the characteristics of an oligopoly.

Sanxin has absolute advantages in terms of technology, production capacity and market share.

2014年第一个量产20nmDRAM工艺之后，再次领先并量产18nmDRAM。SK海力士2017年初量产18nmDRAM。美光目前还停留在20nm的路上，预计2017年下半年完成向1Xnm级别产品的迁移，与三鑫技术差距为达1年左右，行业垄断性有增强趋势。

And if Sanxin's factory building is burned down, it means that the output of memory will drop by 57%, and the supply and demand will be greatly unbalanced, so the price of memory all over the world will inevitably rise sharply.

So these guys' factories will always catch fire or some kind of chemical pollution for no reason, and then the price of memory sticks will soar.

Lao Ma once said: Once there is an appropriate profit capital, it will be bold. If there is a 10% profit, it will be used everywhere; if there is a 20% profit, it will be active; if there is a 50% profit, it will take risks. ; for 100% profit, it dares to trample on all human laws; with 300% profit, it dares to commit any crime and even risk the gallows.

This is the nature of capital.

So to cooperate with these guys, it is best to prepare for the back road, or you may be killed by them.

Xingtu Design Company has preliminarily designed a 5nm-level chip. Of course, because it is a trial design, they directly copied some chip designs from Qualcomm, Intel, and Huawei.

Anyway, this design is just to test the performance of the atomic imprinter, and Xinghe Semiconductor does not intend to produce it for sale, so there is no problem of patent infringement.

This 5nm-level chip consists of a total of 32 layers of circuits.

Therefore, the micro-engraving laboratory needs to carve out 32 layers of circuits, but considering the extraction of a little silicon atoms, it will be very slow, which is not conducive to mass production.

Therefore, Huang Haojie took a different approach. His solution is very simple. Separate the 32-layer circuit, carve a silicon wafer on one layer, and then make nano-needles on the grooves of these circuits to complete the production of these nano-needles.

You can directly make a circuit printer, and these circuit silicon wafers equipped with nano-needles can carve out a layer of circuits at one time.

As long as a silicon wafer is printed 32 times, a 32-layer circuit can be completed.

Of course, in addition to the circuit printing machine, the Semiconductor Research Institute also needs equipment such as circuit injection machines and circuit copper plating machines.

These devices are made based on C31 fullerene, so they are also called carbon nanocircuit production lines.

The first step of this method is to accurately complete the original film, which is the key point of chip production.

The 5nm-level chip designed by Xingtu Company needs 32 original chips. Based on these 32 original chips, 32 circuit printing heads, 64 circuit injection heads, and several circuit copper plating machines are produced.

These original films cannot be wrong, otherwise there will be problems when the chips are produced, or even scrapped.

And once these original films are produced, the next work is very simple.

This situation is equivalent to using a laboratory method to produce a high-precision chip, and then copying the high-precision chip directly, the two produced are exactly the same.

All atomic imprinters are the key equipment of Yinhe Technology, and C31 fullerene is the most important.
