The Black Technology Era of Xueba

As a semiconductor material, silicon carbide has been extensively studied in major laboratories around the world. Among them, as LED lighting or other simple industrial products, it has been industrially produced.

At the same time, the advantages of silicon carbide compared to silicon chips are many.

For example, the wide band gap can reach as high as 3.0eV to 3.25eV, which increases the operating temperature of the chip to more than 800 degrees.

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

Secondly, the high electron breakdown field strength increases the breakdown voltage of semiconductor power devices, and the broadband of the drift region of silicon carbide power devices can be reduced, so the power devices can be reduced, and the chip volume can be made smaller.

Smaller chips are the key to making wearable devices, and users don't want to wear a bulky helmet or a few pounds of tech glasses.

In addition, silicon carbide chips are also highly resistant to radiation, and there will be no problems in working in space or in the field of strong radiation 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 has not been put into practice in major laboratories around the world, mainly due to technical problems.

Modern industrial technology is not enough to put entangled quantum pairs into color centers and perform operations on this basis, and the technical difficulty is still very large.

This is also the current technical bottleneck for the development of third-generation semiconductors. Even if semiconductor chip companies, including Intel, start to use silicon carbide as the third-generation semiconductor material, they are still making binary chips, not quantum chips across the ages.

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

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

"The Tiangong system and the Pangu system ecological chain have made a profit of 300 million yuan. In addition, the Yigou business unit has a profit of 120 million yuan, and Huaze has a dividend of 300 million yuan."

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

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

Those companies in the A-share market are fine if they don’t lose money. There are very few companies that can make a profit of more than 2 billion a year. Many stocks with a profit of only a few hundred thousand a year are good, and they are soaring every day.

"But." Qian Yi looked at the boss's happy face, 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 wages, there is less than 800 million yuan."

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

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

Such huge rewards are not uncommon for Ali and Penguin at the tens of billions level, and these are individual rewards, which do not conflict with the year-end bonus.

"I am inspiring the enthusiasm of employees." Xiao Ming said: "In this era, only relying on ideals and feelings will not stimulate the enthusiasm of employees. Money is an essential part."

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

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

"Yes yes yes!" Qian Yi, as the company's general manager, said, "You have spent tens of millions of dollars rewarding people."

Xiao Ming is thinking about whether the 900 million fund under him is 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 part of the silicon atoms in silicon carbide by substituting silicon carbide with a strong current under high temperature and high pressure, and so on.

These equipments are expensive, and the resistance furnace on the guide is not the resistance furnace of ordinary factories outside. The degree of refinement and yield rate are unmatched by industrial silicon carbide.

In the industry, ordinary resistance furnaces are used to produce black silicon carbide with carbon material as the furnace core. This is because iron and other magazines are mixed in it. 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 sister coins from the development of the equipment to the installation.

This is still a small amount of money, and the biggest expense is photolithography of silicon carbide to form circuits.

Instruments capable of lithography of silicon carbide must be able to lithography of silicon crystals, and Pangu Technology has also broken through the R\u0026D and production technology of traditional silicon crystal chips.

The development and production costs of silicon carbide lithography machines are quite high.

The lithography machine can not be produced by sending the drawings to Xiaxin International or TSMC, but must be developed and produced from the machine that produces the lithography machine.

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

This cost is more than 500 million soft sister coins.

This is not the most expensive, the most expensive is that after the silicon carbide crystal is lithographically etched into the circuit, the electrons in the crystal are excited by laser light, and the entanglement is stored in the color center of the chip silicon carbide crystal using Panshaxing's Feiyang technology. Quantum, which stores quantum information and the logic gates it produces.

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

Of course, the quantum will decay over time, and the quantum storage time is about 36 to 72 hours, which is the longest storage time that surpasses the human quantum.

The principle of silicon carbide chip is that there is constant quantum decay and new quantum and new logic are continuously activated by 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. Quantum decays but the number of rooms remains the same.

The lowest-level quantum chip only needs to ensure that 50 rooms have quantum. It is this low-level quantum chip that completely explodes the most advanced binary chip in the world today.

The computing speed of modern binary chips is only a trillion times per second, while the computing speed of quantum chips in 100 rooms is more than 2 to the 50th power.

Does this technology cost money?

Xiao Ming estimates that the budget is more than 3 billion soft sister coins.

To sum up, all the expenses are about 3.6 to 4 billion soft sister coins, and the costs of factories and the like have not been calculated.

Qian Yi interrupted Xiao Ming's sweet dream and said, "Boss, just now you don't have any debts. We still need about 9 billion yuan for the land in Jiangcheng City."

Xiao Ming waved his hand and said, "This money does not need to be paid, it is paid in installments anyway."

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. One square meter sells for 100,000 yuan. This is money!"

Xiao Ming said: "It's more profitable to sell the land. The residential land in the urban area of ​​Jiangcheng is approaching 20 million per mu."
