Chapter 215 Bill

The 90nm lithography machine that Modu Micropower supplies in batches is obviously far 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 also complicated, and the cost is ridiculously high compared with the same level.

For automobiles, the price of X32115 and 32116 of two or three thousand is nothing; for aerospace, even if the silicon carbide chip production line is used for automatic production, the X32035 with a unit price of tens of thousands of yuan per piece is nothing, and the cost can be ignored in the entire system.

However, for the consumer electronics market, with a shipment volume of tens of millions to hundreds of millions or even billions, a unit price reduction of 10 yuan can bring huge competitiveness and exaggerated profits.

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

Even if the government and confidential units will have a batch of large 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 tactfully expressed that they can only control the cost and yield of 55nm chips to the same level as the mainstream foreign ones, and it will not work if it is higher, the scene of the summit was frozen.

55nm mature process, can this be used?

Even if the ternary BUFF is added, it is impossible to go against the will of heaven. Use tens of millions of analog field effect tubes and more than one billion transistors to fight?

If you can't control the cost, what can you use to compete with the blue, green, and red factories, Samsung and Qualcomm?

Wang Minjiang was also secretly annoyed that he actually forgot this. He was too hasty to become independent. Before, he made chips for car computers and aerospace, and he didn't care much about the cost.

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

"What? Can't get it done before 2020? Impossible."

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

ASML in the Netherlands is not based on its own strength. It relies on a huge supply chain composed of thousands of companies around the world, including China. If chips are to be produced, there is another long supply chain on the production line. It is really not a problem of a technological breakthrough.

Lin Ju thought about it and tried to create a new task in the system research institute:

[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 invest 50 million in it.

The progress increased from 0% to 0.01%.

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

It seems that it is unlikely to accelerate with the system.

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

This fully automatic production line is powerful. You only need to buy highly purified raw materials and feed them in from the feed port. This production line, which occupies a considerable underground and ground area, will automatically perform a series of processes such as cutting, etching, and packaging. It is the blackest technology among black technologies.

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 strength is simply unimaginable.

But no one dares to dismantle it. The cleanliness inside such a sophisticated equipment must be higher than that of a clean room. If it is dismantled, it will definitely be useless.

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

This difficulty... I am afraid it will not be much lower than directly studying the 7nm process of silicon chips, and it may even be higher.

On July 27, Wang Minjiang, who had been in contact with Lin Ju all night, 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 told them the problems he encountered.

Hearing that the ternary system might be difficult to implement due to cost factors, the superiors' initial reaction was disappointment and a little calmness.

There is no such thing as overtaking on a curve. Every step must be taken steadily. It was because he was too anxious.

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

Those overseas Chinese who provided ternary enthusiasts are also big names in major chip design and manufacturing companies, and there are many related to lithography machine technology.

They are not good at providing technical information directly, but they can provide guidance on certain key technologies through secret channels and over the phone, and even bring people from other countries.

If Modu Microelectronics or Huaxin International needs it, they will take people to Xinyuan Company to make confidential contacts through the Jingwei satellite network. Asking for some key technologies may be helpful, but these instructions are not without cost. 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 billions, but it must be guaranteed to be solved.

The superiors asked Wang Minjiang to go back first, and then waited until the last day of the recess. When the representatives attending the summit were about to despair, the Science and Technology Commission ordered that 7 domestic state-owned chip manufacturing-related companies send technical experts to secretly gather with the current technical problems.

At the same time, the semiconductor summit was 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 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 a contract as an external consultant of the microelectronics department of 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 thought it was a big problem. A contract could not restrict anything.

On the 28th, 29th, and 30th, 43 external researchers were secretly gathered in a single-family building in Xinyuan, where they stayed in a nearly closed environment for 96 hours. More than 70 extremely critical technical difficulties and more than 20 chemical raw materials and special materials synthesis and processing processes were proposed.

In secret, Lin Ju looked at 3 A-level scientists, 9 B+-level engineers, and 31 B-level engineers, and was shocked.

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

The official only made a slight move and brought out an unimaginable rich talent pool.

It only shows that there are really many powerful people, but he has no intention of embezzling any money. He formed a chip technology public relations team with these luxurious researchers, and then listed the hundreds of most critical technical difficulties they encountered into system tasks and began to study.

Four days later, when these 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 a bill of 10.2 billion yuan to his superiors.
