I ask you to build tractors, but you build rockets?

Currently, Modu Micropower supplies 90nm lithography machines in batches, which is obviously far away from 40nm. 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 complex, and the cost is ridiculously high compared to similar products.

For cars, the price of two to three thousand yuan for X32115 and 32116 is nothing; for aerospace, even if it is automatically produced using a silicon carbide chip production line, X32035, which costs tens of thousands a piece, is nothing, and the cost of the entire system can be ignored.

But for the consumer electronics market, with shipments ranging from tens of millions to hundreds of millions or billions, a 10 yuan reduction in unit price can bring huge competitiveness and exaggerated profits.

Everyone's ideas are good, and China's chip design capabilities are not bad. However, if the cost of producing chips is too high and they cannot be sold, it will be very troublesome.

Even though there will be a large number of orders from the government and confidential units, can they compare with the huge civilian market?

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

When He Yuming euphemistically expressed that currently they can only control the cost and yield rate of 55nm chips to be the same as the mainstream foreign levels, and no higher, the scene at the summit froze.

55nm mature process, can this be used?

Even if there is a ternary BUFF bonus, there is no way to go against the odds. How about using tens of millions of analog field effect transistors and more than a billion transistors to give it a try?

If you can't control costs, what can you do to compete with blue, green, red factories and Samsung and Qualcomm?

Wang Minjiang was also secretly annoyed that he had forgotten about this, and was too hasty to become independent. Before, he only made chips for automobiles and aerospace, and he didn't really care about the cost.

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

"What? Can't it be done before 2020? It's impossible."

Although he said it was impossible, Lin Ju still believed it. The lithography machine was an extremely complex system. The low-end ones were fine, but only ASML could produce the high-end ones.

ASML in the Netherlands does not rely on its own strength. It relies on a huge supply chain composed of thousands of companies around the world, including China. If you want to produce chips, the production line is a long supply chain. It is really not A technological breakthrough.

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

[New task: develop photolithography machines and supporting chemical raw materials that can produce 14nm chips with a yield rate of more than 96%

Current progress: 0%】

Then, he tried investing 50 million.

The progress has increased from 0% to 0.01%.

Calculate it in your mind. In other words, it will cost 500 billion to push it to 100%?

It seems impossible to use system acceleration.

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

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

Input the design drawings and several raw materials, and then wait for a month, and the chip will come out. Although the output is small, the technical power involved 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. It will be useless if it is dismantled.

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

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

On July 27, Wang Minjiang, who had been in contact with Lin Ju all night, announced that the meeting would be temporarily adjourned for three days.

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

Upon hearing that the ternary system might be difficult to implement due to cost factors, the superior's initial reaction was disappointment and a trace of calmness.

There is no need to overtake on a curve. Every step must be done steadily. It's because I am too anxious.

But just when he was disappointed, Wang Minjiang made up his mind and told him unexpected news:

Those overseas Chinese who provide ternary enthusiasts are also the masters of major chip design and manufacturing companies, many of which are related to lithography machine technology.

They cannot provide technical information directly, but they can provide guidance on certain key technologies over the phone through secret channels, and can even recruit people from other countries.

If Modu Microelectronics or Huaxin International needs it, they can take people to Xinyuan Company to contact them confidentially through the Jingwei satellite network and ask about some key technologies. It may be helpful, but these guidance are not without cost. They need money, a lot of money. It can be compensated by Xinyuan Company.

According to Wang Minjiang, the price of a problem may be calculated in hundreds of millions, 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 all the representatives participating in the summit were in despair, the Science and Industry Committee ordered that seven domestic state-owned chip manufacturing-related companies send technical experts to bring the problems they encountered so far. Technical difficulties gathered in secret.

Meanwhile, the Semiconductor Summit adjourned for another four days.

The order came from a very high level. In one afternoon, the core research team leaders of major companies were gathered together and quietly flew to Xinyuan Company on eight flights.

On the plane, a total of 43 experts from various related fields of chip manufacturing not only signed a confidentiality agreement, but also signed a contract as an external consultant for the Microelectronics Department of Xinyuan Aerospace Power Research Institute, and can enjoy certain allowances and benefits every year. .

Wang Minjiang said that this was Factory Director Lin's request, and no one thought there was a big problem. A contract could not restrict anything.

On the 28th, 29th, and 30th, 43 external researchers were secretly gathered in a small single-family building in Xinyuan. They stayed in near isolation for 96 hours and proposed more than 70 extremely critical technical difficulties and more than 20 kinds of technical problems. Synthetic processing technology of chemical raw materials and special materials.

In the dark, Lin Ju looked at 3 A-level scientists, 9 B+-level engineers, and 31 B-level engineers, grinning from ear to ear in shock.

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

With only a slight intervention, the officials came up with an unimaginably rich talent pool.

It can only show that there are still many powerful people, but he has no intention of taking it for himself. He formed a chip technology public relations team with these luxurious researchers, and then listed hundreds of the most critical technical difficulties they encountered in the system. Task, start research.

Four days later, when the 43 researchers came out, the people who greeted them found that although they looked a little unkempt and unkempt, they were in unexpectedly good spirits.

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