Regarding Xingchen's guess, Chen Chen did not answer because his goal was not clear.

Because in the current political landscape of the earth, there are many things that cannot be accomplished even if you want to do it.

On a planet without a unified government, how to carry out the next stage of civilization advancement, Chen Chen had no experience to think about.

So for the time being, we can only take one step at a time.

After Chen Chen and Xingchen discussed and decided, Xingchen spent about 3 hours to integrate all other functional modules such as processors and basebands, and conducted many simulation tests to ensure that there were no problems at all.

Then all the information, as well as a complete set of 5G communication standard documents, were sent to Chen Jiansheng, asking him to find time, hand over the processor to intel for production, and then take the 5G communication standard to prepare to participate in this year's communication industry conference.

Generally speaking, a chip foundry starts from the time it obtains a chip production order from a customer.

All the wafers needed to be produced for the customer within 60 days, and it took about another month after the wafers had been packaged and tested.

That is to say, it will take at least 80~90 days from start to delivery.

The time is a bit long, mainly because the mature lithography machine 193i used at present has been used for many years, and its accuracy is very low, and it needs to be used to produce 14nm chips, which requires excessive and complex technology to increase accuracy.

The traditional process, to achieve 10nm, is basically the limit, if you want to continue to explore, to 7nm, 5nm, you must change the new technology.

This new technology, that is, intel, Samsung, TSMC, are all waiting for EUV extreme ultraviolet lithography technology. Projection lithography technology with a wavelength of 13.5nm extreme ultraviolet light as the working wavelength is used

Because of the higher precision, the process flow and complexity can be greatly reduced.

Therefore, if EUV lithography technology can mature and put into mass production, the production time of chips will be greatly shortened, and the product yield will be greatly improved.

According to current estimates, factories using EUV technology can leave the factory in more than 20 days at the earliest, which is only a quarter of the time of traditional lithography technology.

However, at present, EVU technology is not mature, and there are still several key problems that have not been solved.

Intel, Samsung, and TSMC Semiconductors have invested huge sums of money in ASML, the world's top lithography machine manufacturer, to develop EUV technology in order to maintain the sustainable development of the semiconductor industry.

EUV technology is the hope of continuing Moore's law and making the 7nm and 5nm processes successfully mass-produced.

Moreover, EUV technology is also a rare opportunity for Donghua's domestic semiconductor manufacturing technology to achieve corner overtaking and surpass the world.

In terms of traditional craftsmanship, it is difficult for Donghua to surpass the West, and even if it does, it will soon become obsolete and can only be used to produce low-level chips.

In the 90s of the last century, Donghua began to conduct research on EUV-related aspects.

In 2002, the first set of EUV extreme ultraviolet lithography principle device was developed.

In 2008, under the leadership of the Chinese Academy of Sciences, a number of universities and scientific research institutions have participated in the research.

In 2017, the research on the key technology of EUV extreme ultraviolet lithography has reached the final stage of tackling key problems, and the project acceptance is about to be carried out.

In fact, at this time, purely in terms of EUV's lithography machine technology, it is the most recent one for Donghua International and is almost within the same generation.

And the key is that whenever China engages in tackling key technological problems, it is necessary to make a complete set of technologies.

Including all kinds of materials and equipment used in the production process, the overall technical research will be carried out, because if you don't do it yourself, no one will sell other equipment and processes to you.

ASML, on the other hand, can source the best materials in different countries.

The prospect seems to be very good, but like ASML, it still cannot be mass-produced, and domestic EUV is more difficult to mass-produce than foreign countries, because the supporting system cannot keep up and needs overall research and development.

In this context, Intel's 7nm wafer factory drawings and technology to Xingchen Semiconductor are still semi-finished products, and there are multiple sets of immature backup solutions.

Is EUV technology necessary to achieve 7nm? Can EUV technology catch up with the mass production of 7nm? Intel itself has no bottom.

Therefore, if you follow intel's drawings, the factory construction will be final, and it will inevitably move to the experimental stage, and the traditional process and EUV will be tested, rather than directly mass-produced, and intel itself is the same.

However, after the revision of Xingchen, this drawing is already perfect, mature, and certain.

Xingchen casually solved the problem of EUV dystocia.

The equipment required for the construction of the factory already includes EUV equipment, and both domestic and ASML are available.

The main thing is that the production capacity of this thing is too low, ASML only ships 12 units a year, and the domestic production capacity is even lower, in order to improve the output and scale of the factory in the future, you can buy one more to buy more.

The undertaker of the domestic EUV project is also one of the shareholders of Xingchen Semiconductor, and it is one of the only technical shareholders in addition to Xingchen Technology.

At the same time as the factory is being built, Xingchen Technology will help them to directly mature the equipment that is still in the laboratory to mass production.

And during the whole construction process, Intel's people can't interfere at all, unlike the previous technical cooperation with other countries, the students here will chase the experts over there and study desperately.

This construction process, and even in some places, will keep Intel's secrets and isolate Intel's people.

Chen Chen knew that if nothing else, Xingchen Semiconductor's factory would be completed at a very fast speed.

And it can be directly mass-produced after completion, and then blind the eyes of Intel, Samsung, and TSMC.

But now it is obviously not needed, and Intel can only produce its own processors with traditional lithography.

Therefore, Xingchen Technology's processor order will take three months to be delivered at the earliest.

However, Chen Chen is not in a hurry, the processor needs time, and other accessories also need time.

So on the whole, the second generation of Xingchen mobile phones should be launched in the fourth quarter and before winter.

In the following time, Chen Chen's life became easier again.

Every day during the day, I accompany my sister and take a few maids to drink tea, watch animations, play games, soak in hot springs, go shopping, or go to Xingchen Technology to fill people's heads, or go to Xingchen Semiconductor under construction to inspect and see the scenery.

In the evening, I went to chat with Qingkong to cultivate feelings, and at the same time, I also worked with Qingkong to carry out follow-up game market planning.

Every day, Chen Chen will also take time to chat with Lin Qian and Sikong Yue and exchange feelings.

A few days ago, Lin Qian went out on a trip with several female teachers and posted photos of various scenic spots in the space.

Lin Qian also told Chen Chen that she was accosted by a high school student in the scenic spot, Lin Qian smiled and talked for a long time, while Chen Chen was helpless.

Lin Qian's dress is becoming more and more girly, and the whole person has a tendency to grow in reverse.
