Now Modu Microelectric Energy supplies 90nm lithography machines in batches, which is obviously not a small distance from 40nm, and it is already very difficult for the former to produce 28nm.

Not only is the yield rate low, the output is relatively small, the process is also complex, and the cost is ridiculously high compared with the same level.

For cars, the price of two or three thousand for X32115 and 32116 is nothing; For aerospace, even if the silicon carbide chip production line is used for automatic production, the unit price of X32035 is not much if it is tens of thousands of pieces, and the cost can be ignored in the entire system.

However, for the consumer electronics market, for shipments of tens of millions or billions of dollars, a reduction in unit price of 10 yuan can bring huge competitiveness and exaggerated profits.

Everyone's ideas are very good, and Huaguo's chip design ability is not bad, but if the cost of the produced chips is too high, it will be very troublesome if they can't be sold at all.

Even if the government and secrecy units will have a large number of orders, can they compare with the huge civilian market?

No, the chip cost of Huaxin International's 28nm production line is several times more expensive than TSMC's 14nm, which completely violates the law of semiconductor development and should not be produced.

When He Yuming euphemistically expressed that at present, they can only control the cost and yield rate of 55nm chips to the same level as the mainstream level abroad, and no matter how high it is, the scene of the summit froze.

55nm mature process, can this work?

Even if the ternary buff is bonus, you can't go against the sky and fight with tens of millions of analog FETs and more than a billion transistors, right?

If you can't control the cost, what can you do to fight with the blue-green-red factory and Samsung Qualcomm?

Wang Minjiang was also secretly annoyed that he had forgotten this stubble, and he was in a hurry to become independent, and he used to make chips for car engines and aerospace, and he didn't care much about the cost.

So the day's summit was temporarily suspended, and Wang Minjiang asked Lin Ju for help overnight.

"What? Can't do it before 2020? Impossible. ”

Although it was impossible to say that it was impossible, Lin Ju still believed that the lithography machine was an extremely complex system, and the low-end one was fine, and the high-end one could only be produced by ASML.

ASML in the Netherlands is not based on how good it is, it relies on a huge supply chain composed of thousands of companies around the world, including China, to manufacture, if you want to produce chips, there is a long supply chain on the production line, and it is really not a problem of technological breakthrough.

Lin Ju thought about it and tried to create a new task in the System Research Institute first:

[New task: Develop a lithography machine and supporting chemical raw materials that can produce 14nm chips with a yield rate of more than 96%.

Current Progress: 0%】

Then, he tried to put 50 million into it.

Progress increased from 0% to 0.01%.

Calculate in your mind, that is, it will cost 500 billion to advance to 100%?

It seems unlikely that acceleration with the system will be possible.

Then the only way left is to see if it can be obtained from the base, which is the fully automatic production line that can produce 14nm silicon carbide chips.

This fully automatic production line is powerful, only need to purchase highly purified raw materials, from the feeding port, this production line occupies a considerable underground and above-ground area to automatically carry out a series of processes such as cutting, etching, packaging, etching, is the black technology of the black technology.

Enter the design drawings and several raw materials, and then wait a month, and the chip will come out, although the production is small, but the technical force in it is simply unimaginable.

But no one dares to dismantle it, the internal cleanliness of such a sophisticated equipment must be higher than that of a clean room, and it is absolutely useless to dismantle it.

If you really want to study the technology inside, you can only build a new B-class base, and then dismantle the production line inside for reverse imitation.

This difficulty...... I'm afraid it won't be much lower than directly studying silicon chips to reach the 7nm process, and maybe even higher.

On July 27, Wang Minjiang, who had been in contact with Lin Ju overnight, announced a temporary adjournment for three days.

At the same time, Wang Minjiang easily met with his superiors, who were extremely concerned about the summit, and talked about the problems he encountered.

Hearing that the ternary system may also be difficult to implement due to cost factors, the initial reaction of the superiors was disappointment and a hint of calmness.

There is no overtaking in any corner, every step must be steady, it is too anxious.

But just when he was disappointed, Wang Minjiang made up his mind to say a news that he didn't expect:

Those overseas Chinese who provide ternary enthusiasts are also big names in major chip design and manufacturing companies, and there is no shortage of them related to lithography machine technology.

It is not easy for them to provide technical information directly, but they can give guidance on certain key technologies through secret channels by telephone, and can even bring in people from other countries.

If Modu Microelectronics or Huaxin International needs it, they will take someone to Xinyuan Company to make confidential contact through the Jingwei satellite network and ask about some key technologies, which may be helpful, but these guidance are not without a price, they need money, a lot of money, which can be compensated by Xinyuan Company.

According to Wang Minjiang, the price of a problem may be calculated in 100 million yuan, but it must be guaranteed to be solved.

The superiors first asked Wang Minjiang to go back, and then waited until the last day of the adjournment, when the delegates attending the summit were desperate, the Commission of Science and Technology ordered that seven state-owned chip manufacturing related enterprises in China send technical experts to secretly assemble with the technical problems they are currently encountering.

At the same time, the Semiconductor Summit was adjourned for another four days.

The order came from a very high level, and in one afternoon, the leaders of the core research teams of major enterprises were gathered and quietly flew to Xinyuan Company in eight flights.

On the plane, a total of 43 experts from various related fields of chip manufacturing signed a confidentiality agreement and signed a contract for external consultants of the microelectronics department of the Xinyuan Aerospace Power Research Institute, which can enjoy certain allowances and benefits every year.

Wang Minjiang said that this was the request of Director Lin, and no one felt that there was too much of a problem, and a contract could not bind anything.

On the 28th, 29th, and 30th, 43 external researchers were secretly gathered in a small building in Xinyuan, where they stayed in a closed place for 96 hours, proposing more than 70 extremely critical technical difficulties, as well as more than 20 kinds of synthetic processing technologies of chemical raw materials and special materials.

In secret, Lin Ju looked at 3 A-level scientists, 9 B+-level engineers, and 31 B-level engineers, and couldn't close his mouth in shock.

The superiors really believed it, so they really sent the country's top scientific researchers.

With just a slight move, the official has come up with an unimaginably rich pool of human resources.

It can only show that there are really many fierce people, but he doesn't have any intention of daring to swallow it privately, and forms a chip technology public relations team with these luxurious lineup of researchers, and then includes the hundreds of most critical technical difficulties they encounter into the system task and starts researching.

Four days later, when the 43 researchers came out, they were greeted by a surprisingly good spirit, although they looked a little unkempt and unkempt.

At the same time, Wang Minjiang handed over a bill of 10.2 billion yuan to his superiors.
