Chapter 398 Chip Manufacturing's Hope of Overtaking in a Corner (seeking a monthly ticket)

Mu Yang promised Zhang Lan that he would not act immediately before going to Shangfei Company, and he had to let him do ideological work for Shangfei's people first, and let him ventilate first.

The two parties still have some details to discuss. For example, Muyang helped Shangfei solve technical problems, how to calculate the ownership of the technical patents generated in it, and how to calculate the patent benefits. The group also doesn't want to take money.

For example, if Xinghai Group and Muyang didn't make use of the technology and conditions of Shangfei to produce an aircraft engine, it must be Muyang's own thing, and it has nothing to do with Shangfei.

However, if the new things developed by SAIC are used, the two companies should be able to use the patents for free. As for the benefits generated by the licensing of the patents, the proportion of each party will depend on the respective contribution ratios of each party.

Shanghai Aircraft Corporation is not small, with a registered capital of 50 billion yuan and currently employs nearly 10,000 people. It can be seen from this that it is too expensive to build a large aircraft.

In fact, the size of the company is nothing compared to the Xinghai Group, mainly because of the background of Shangfei and the meaning it represents.

This is also the reason why Mu Yang is willing to help. He is also willing to contribute to the country without harming his own interests, and sees the large domestic civil aviation aircraft flying to the world.

Therefore, the interests that should be fought for still need to be fought for.

He didn't intend to develop and produce large civil aviation aircraft either, and he was not very interested, so he would not use the technology of Shanghai Aircraft Corporation to manufacture civil aviation aircraft.

He knew the future development trajectory of large civil aviation aircraft, and the aero engine was still being manipulated by foreigners. Mu Yang who knew this was very upset.

Mu Yang included the aero engine in Xinghai Group's research and development plan, and will not disclose it to the outside world, including Shanghai Aircraft Corporation.

The cooperation agreement signed between Shanghai Aircraft Corporation and CFM will eventually be invalidated.

Beautiful Country is very treacherous, knowing that they have signed a cooperation agreement, there is no restriction at the beginning, after the first flight of Shanghai Aircraft Company, it is ready to go on sale, and then Shanghai Aircraft Company will be established to make the development of China Civil Aviation fall short. The ambition of Shangfei Company was gone at once.

In this way, Mu Yang is also secretly researching and developing aero-engines. When Shangfei is restricted, his own aero-engines will appear again. This will be suitable, and it will also catch the beautiful country by surprise. At that time, the sanctions will be a joke.

For Shangfei Company, Xinghai Group’s timely delivery of charcoal is much better than the current statement that it will develop an engine. The credibility is too poor, just like Xinghai Group’s plan to develop chips, the outside world is not optimistic.

Moreover, the Xinghai Group's announcement of the development of the engine must be subject to various restrictions from the beautiful country, and it may directly sanction the Xinghai Group.

In fact, it is also in an embarrassing situation at present. The Hummer EV is selling well, providing jobs for the locals in the beautiful country, and fighting for face. It is right to say that the Hummer is from the beautiful country, and it is also right to say that it is from the beautiful country.

If Xinghai Group is sanctioned, it is a slap in the face, and many of the products sold by Xinghai Group are not available in the beautiful country. Now sanction/sanction Xinghai Group, what a joke, it is actually sanction/sanction itself.

Therefore, the Xinghai Group exploited a lot of loopholes, making it impossible for them to fight.

It's just that they don't want to see Xinghai Group develop,

If the Xinghai Group really engages in wafers and chips, it will definitely be sanctioned, but only in this respect, and will not comprehensively sanction the Xinghai Group.

What they want to do the most is to tie Mu Yang to Beautiful Country, but for some reason, Mu Yang seems to have seen through something, but he doesn't want to go abroad, and has been invited to come to Beautiful Country for academics many times, but people say he has no time.

Let's present the award, and someone will replace it, but I didn't say there was no time.

Receive the award in person?

Sorry, this award is no longer available.

Anyway, Mu Yang took advantage of all the benefits and let others make a fuss for nothing.

After Zhang Lan left, Mu Yang transferred to work on 3D drawing software.

After a while, he is going to start working on the wafer project.

The plan started last year, and the company has successively recruited talents in this field, plus master and doctoral students who have been working in the company for a year or two, it is time to start the real work.

Now Mu Yang has not started to purchase wafer manufacturing and chip manufacturing technology, but just set up the personnel framework first.

Wafer manufacturing is not as complicated as chip manufacturing. Only chip manufacturing uses lithography machines and etching equipment, while wafer manufacturing does not need it. It is completely different.

Since 2007, the 12-inch wafer has become the mainstream standard size, that is, the diameter is about 304.8 mm, which refers to the imperial system, not the metric system. One inch = 3.33 cm.

In 2013, the mainstream wafer size was still 12 inches, the second-rate was 8 inches, and 18 inches was also developed. However, even in 2022, Mu Yang had never heard of 18-inch wafers being put into production, mainly due to the low yield rate of wafers.

Of course, the larger the diameter of the wafer, the better, but also the more difficult it is to make, and the higher the requirements for equipment.

We often hear that the chip process is 28nm, which means that the distance between the circuits in the IC is 28nm, and the smaller the better.

The limit of 8-inch wafers is basically 90nm, and the 28nm, 14nm, and 7nm chip processes we know can only be made on 12-inch wafers, which is why it is emphasized to produce 12-inch wafers.

The leading representative of Huaguo wafer production is Zhongxin International, which was established in 2000. In 2009, there were three factories producing 12-inch wafers. It just said that the yield rate was not as good as that of international giants. In terms of chip manufacturing process level, in 2010 At the end of the year, mass production of 65nm has been achieved. At present, mass production of 28nm has not yet been achieved.

What Mu Yang learned about domestic wafer and chip technology levels is the case for the time being. This is the information he asked the relevant departments of the company to investigate and collect. He must first understand the domestic and foreign situations.

If Xinghai Group wants to engage in wafer production, it must start with 12-inch wafers, and the chip process should start with 28nm, otherwise there is no need to enter this industry.

In later generations, Mu Yang also learned that chip manufacturing does not necessarily use lithography machines and etching equipment, such as electron beam lithography technology. Mass production.

Mu Yang also checked and found that there is indeed electron beam lithography technology, which also cannot achieve mass production, but it can be produced in the laboratory and used for quantum computers.

If he intends to commercialize, he still has to follow the line of lithography machines. When the time comes, he can use electron beam lithography technology to overtake cars directly on curves. What kind of shit lithography machine is used.

At this time, maybe it is the Level 7 Reading System.

But even if electron beam lithography technology can be used to produce process chips with a line width below 10nm, it is not yet so sophisticated in the commercial market.

Mu Yang's expectation is that even if the precision is lower, as long as the energy is produced, the cost can be reduced, and there is no need to use any nonsense lithography machine.

Now the technical patents of the lithography machine line are estimated to have been applied for. Even if Xinghai Group can make equipment such as lithography machines, so what, if it can't bypass the other party's patent coverage, if the other party does not authorize, he has no It can not be produced by using the lithography machine developed by itself.

Unless Xinghai Group can bypass the patent coverage of the opponent's lithography machine, this road is too difficult to walk.

It is impossible to expect the other party to authorize the patent. Mu Yang felt a sense of aggrieved inexplicably.

So, now Mu Yang is counting on the level 7 reading system.

It is estimated that the upgrade of the Level 7 reading system will be realized by the end of the year.

There is no rush at the moment, let's get the wafer out first.
