As a semiconductor material, silicon carbide has been extensively studied in major laboratories around the world, and has been industrialized as LED lighting or other simple industrial products.

At the same time, there are many advantages of comparing silicon chips with silicon carbide.

For example, wide bandgap can reach as high as 3.0 eV to 3.25 eV, increasing the operating ambient temperature of the chip to more than 800 degrees.

This kind of temperature tolerance will not be needed in the future, and it can be used in places with harsh conditions such as space exploration.

Secondly, the high electronic breakdown field strength brings about the increase of the breakdown voltage of semiconductor power devices, and the broadband in the drift region of silicon carbide power devices can be reduced, so the power devices can be reduced, and the chip size can also be made smaller.

Smaller chips are key to making wearables, and users don't want to wear a bulky helmet or a few pounds of tech glasses for an X.

In addition, silicon carbide chips are also highly resistant to radiation, so there will be no problems working in space or strong radiation fields in the future. Ordinary chips or electronic products will basically lose their ability to work in places with strong radiation.

However, the use of silicon carbide as a chip, the world's major laboratories have not put it into practice, the main reason is technical problems.

Modern industrial technology is not enough to put entangled quantum pairs into the color center and calculate based on it, and the technical difficulty is still very great.

This is also the technical bottleneck of the current development of the third generation of semiconductors, including Intel, semiconductor chip companies, even if they start to use silicon carbide as the third generation of semiconductor materials, they are also making binary chips, not cross-era quantum chips.

The next day, Xiao Ming called Qian Yi to the office, and he needed to know how much the company's assets were.

Qian Yi turned out the system ledger and said: "The total revenue of Tiangong operating system and Pangu system is 1.4 billion RMB, and manufacturers such as Huawei and Xiaomi have not yet shipped, so the funds are not in place. ”

"The ecological chain of Tiangong system and Pangu system has made a profit of 300 million yuan, in addition to the profit of 120 million yuan in the Yigou business division, and the dividend of 300 million yuan in VATS COMPANY. ”

Qian Yi said: "The total profit was 2.12 billion yuan. ”

It is quite good that a company that has just been established for more than a year can have such a level of profitability! At least the major leather bag companies in the A-share market have been completely exploded.

Those companies in the A-share market are good if they don't lose money, and there are even fewer that can make a profit of more than 2 billion yuan a year, and many stocks with a profit of only a few hundred thousand a year are good, and they are rising wildly every day.

"But. Qian Yi looked at the boss Meizizi's appearance, and couldn't bear to hit him for three seconds.

"But we have paid more than 900 million yuan for land, and after deducting daily expenses such as staff salaries, there are still less than 800 million. ”

Qian Yi pointed out Xiao Ming's shortcomings and said, "Boss, are you too good to your employees?"

Xiao Ming is indeed very generous to employees, after the Pangu and Tiangong systems came out, Xiao Ming rewarded the experimental team with an average of 500,000 RMB, and after the gene expression regulation and phagocytosis II colonies came out, Xiao Ming rewarded Gao Siqi's team with 300,000 yuan per person.

Such a huge reward is not common at the level of 10 billion Arry and penguins, and these are single rewards, which do not conflict with the year-end bonus.

"I'm motivating my employees. Xiao Ming said: "In this era, relying only on ideals and feelings will not stimulate the passion of employees, and money is an indispensable part. ”

If you want the horse to run, you have to let the horse graze, and the bonus system is an important incentive system in Pangu Technology.

What Xiao Ming wants is that employees can be willing to pay for the company, instead of working in front of you here and scolding you behind your back.

"Yes, yes!" Qian Yi, as the company's chief housekeeper, said: "You have spent tens of millions of dollars on rewarding people. ”

Xiao Ming was thinking about whether the 900 million funds under him were enough for the experiment of quantum chips.

Several important equipment in the experiment, such as resistance furnace equipment for the production of silicon carbide, such as some silicon atoms in silicon carbide in the way of carbon silicon substitution with high temperature and high pressure with high current, etc.

These equipment are all expensive, and the resistance furnace on the guide is not the resistance furnace of ordinary factories outside, and the degree of refinement and yield rate are incomparable to that of industrial silicon carbide.

In the industry, the silicon carbide black produced by using carbon material as the core of the furnace is made of ordinary resistance furnace, which is because it is mixed with iron and other magazines, and in the ordinary process, it is a more complicated process to remove all the iron.

The silicon carbide that can be used as a chip must be pure and transparent, so it is more difficult to manufacture.

Xiao Ming preliminarily estimated that it would cost about 100 million soft girl coins from the development to the installation of the equipment.

This is still a small amount of money, and the biggest expense is to lithography the silicon carbide and let it form a circuit.

Instruments that can lithography silicon carbide must be able to lithography silicon crystals, and Pangu Technology has also broken through the R&D and production technology of traditional silicon crystal chips.

The development and production costs of silicon carbide lithography machine are quite large.

The lithography machine is not produced by sending the drawings to Xiaxin International or TSMC, but from the production of lithography machines, the machines must be developed and produced.

It is equivalent to Pangu Technology rebuilding a complete industrial chain.

This cost is more than 500 million soft girl coins.

This is not the most expensive, the most expensive is to photolithography the silicon carbide crystal into the circuit, excite the electrons in the crystal through a laser, and use Panshacin's Feiyang technology to store the entangled quanta in the color center of the silicon carbide crystal of the chip, store the quantum information and the logic gate it generates.

The logic gate here is the three typical states, yes, no, yes or no.

Of course, quanta decay over time, and the time of quantum storage is about 36 to 72 hours, which is already the longest storage time beyond human quantum.

The principle of silicon carbide chips is that there is continuous quantum attenuation and new quantum and new logic are constantly activated by the laser, so as to achieve a cycle of use to ensure that the chip can be used normally.

Color centers are small rooms where quantum and logic are stored. The quanta decay, but the number of rooms is constant.

The lowest-level quantum chip only needs to have 50 rooms with quantum. It is this kind of low-level quantum chip that completely explodes the world's most advanced binary chip today.

Modern binary chips can perform trillions of operations per second, while a 100-room quantum chip is more than 2 to the 50th power.

Does this technology cost money?

Xiao Ming estimated that the budget was probably more than 3 billion soft girl coins.

To sum up, all the expenses are about 36 to 4 billion soft sister coins, and the cost of factory buildings and the like is not counted.

Qian Yi interrupted Xiao Ming's dream and said, "Boss, just now you didn't have a debt, we still have about 9 billion yuan of land in Jiangcheng City." ”

Xiao Ming waved his hand and said, "This money doesn't need to be paid, anyway, it's paid in installments." ”

He said in his heart: "But there is still a gap of more than 3 billion, how to fill it?"

Qian Yi said: "It's better to invest in real estate, look at those large real estate companies, sell 100,000 yuan per square meter, this is money!"

Xiao Ming said: "It is more profitable to sell land, and the residential land in the urban area of Jiangcheng City is approaching 20 million acres. ”
