Rebirth: I carry a desktop computer inside me

As for the third point, that is, the clean room, the cleanliness level requirements are higher, and the air in the dust-free workshop is more than 10,000 times cleaner than the outside.

Fourth, it is a high numerical aperture mirror, which requires a very flat surface.

If zoomed in to the size of Hua Guo, the undulation of the surface is less than a hair strand.

These difficulties are the obstacles to the development of EUV lithography machines.

Among them, the light source depends on Keyu light source to achieve a breakthrough; Mirrors, rely on OPPLE photoelectricity.

In addition, it is to circumvent patents.

The whole team, which has been divided into 8 groups, is currently mainly engaged in theoretical design.

In this regard, Jiang Cheng exchanged ideas one by one and listened to some of everyone's ideas.

Unlike listening to them introduce themselves, Jiang Cheng talked very carefully at this time, and conducted in-depth discussions on some of everyone's good ideas, exchanging and simulating.

For these R&D engineers, Jiang Cheng was once again mythologized.

Not only did I understand every piece, but I also listened to everyone's introduction, and I wrote down most (in fact, all) people.

This kind of memory is really too devilish.

Of course, this exchange also took Jiang Cheng 7 days, which gave the entire research and development direction a preliminary idea.

Then first of all, if the design emits 13.5nm light.

Asmail used to bombard tin drops, but Jiang Cheng chose a different path.

That is to use two lasers to bombard each other to produce extreme ultraviolet light.

Of course, this is still just an idea, but Jiang Cheng believes that this is a good direction through the in vivo simulation laboratory, and initially chooses the plan for this.

As for the requirements of these lasers, they can communicate with Keyu Light Source according to the parameters of theoretical design, and let them produce and develop.

Secondly, there are mirrors.

Unlike DUV lenses, EUV lithography machines require more reflections.

The reason is actually very simple, that is, the light wavelength of 13.5nm cannot be made through the lens material currently used, and it is impossible to find such a high transmittance material to make a lens.

Therefore, only reflection can be selected.

Jiang Cheng thought that he had to let Xian Zhufeng grind the mirror with his heart.

In addition, there are higher precision double workpiece tables, measurement, calibration and other systems, which are very difficult to achieve.

However, fortunately, the 193nm immersion lithography machine has been domestically produced under the leadership of Jiang Cheng, which is very great for the improvement of the entire lithography machine industry chain.

"Jiang Dong, as soon as you come, everyone's hearts will be stable, and they know what to do." Lou Xiangwan said with a smile, "After the previous recruitment, everyone didn't know what to do, they were a little confused, and there was a lot of discussion, but they never formed an effective method. Originally

, he still didn't know why Jiang Cheng spent so much time communicating in small groups, but now, he understood.

In Jiang Cheng's heart, through this special exchange, he has drawn a blueprint for his EUV lithography machine design.

Rough design sketch.

Jiang Cheng rubbed the acupuncture points on the side of his eyes a little tiredly, and sighed, "You are still not familiar enough with this technology, I plan to transfer Lian Guanghao over and let him continue to lead the research and development."

"That's good, I do personnel management these are very convenient, really let me study technology, still don't have this ability." Lou Xiangwan scratched his head, because in the magic capital, he still spent a lot of time learning related knowledge.

But after all, I didn't learn this major, and I didn't like Jiang Cheng, I can only say that I understand a little, but I don't understand too much.

Jiang Cheng continued, "At that time, Wang Yang will be the general manager of Moduwei (Pengcheng) Company, and you will be the deputy general manager, and the specific division of labor will be approved by the board of directors of Wang Yangbao.

"Okay, thank you Jiang Dong."

Lou Xiangwan was a little excited, although when Jiang Cheng came to Pengcheng, he had already said to let him recruit a team, and if it was done well, he could be the vice president, but now Jiang Cheng said this, obviously recognizing his recruitment and recruitment work in the past few months.

Jiang Cheng smiled, and then said seriously, "Okay, do a good job, today's magic capital microelectronics, and the past has changed a lot, I remember your credit, now that I have changed to a new position, I still have to continue to struggle, but I can't be embarrassed."

"Don't worry!" Lou Xiangwan patted his chest and said.

"In terms of equipment, I have added some equipment and instruments according to the communication situation and R&D plan, you are responsible for purchasing, if there is any problem, you contact this friend." Jiang Cheng then wrote him Jack Owen's phone.

This kid is probably vacationing in Yunfeng Province now.

Let him help with some instruments, as long as it is not embargoed, it is generally still possible.

Lou Xiangwan nodded in response, and then left first.

Jiang Cheng thought about it while resting, and only then informed Zhang Xiaoyong that he was ready to return to Kyoto.

However, as soon as the matter was explained, Zhang Liang of Changhe Storage Company made a phone call.

"Jiang Dong, our Changhe granules have shipped more than 1 million pieces, it is Guangwei Company that has decided, and they are ready to officially launch DDR3 and DDR4 Guangwei memory on 6.18."

"Oh?" Jiang Cheng was a little surprised, in his impression, because Changhe's memory particles have just come out, many manufacturers still have concerns, and Guangwei is relatively powerful.

After testing the memory particle performance, he immediately placed an order and put out the Yi series memory.

All of them are long river memory.

It can be said that even if it is not the use of Jiangcheng's Shenlong chip, the use of Intel or agricultural enterprise chips to complete the DIY desktop, in the memory, solid-state drive, there are already domestic brands, into the market competition.

For consumers, this is good news that can prompt the three major foreign memory manufacturers to reduce prices.

Jiang Cheng searched for some current news.

Sure enough, the memory stick, which was still at a high level, quickly lowered the price under the pretext of 6.18.

4GB DDR4 memory stick, one has fallen to 379 yuan.

And there is also a trend of price reductions.

Many UP owners are reminding everyone that wait a little longer, the domestic Guangwei memory will come soon.

Zhang Liang is very happy, "Now we have two memory production lines, with a monthly production capacity of about 4.5 million pieces, and the yield rate is still high, which is currently around 94%.

"Good! In the next step, you will follow the pace of foreign manufacturers, gradually increase the frequency on DDR4 memory, and at the same time, for DDR5, you must also start research. Jiang Cheng reminded.

For memory, Jiang Cheng's Maple Fire Group has developed a barrier memory, both in terms of speed and capacity, there are huge advantages, so he is actually not interested in the existing DDR series memory.

But he also understands that the demise of a thing is not so fast, not to mention, this kind of memory stick is still very marketable.

"Okay, I just don't know when Jiang Dong will you come to the company to guide the work?" Zhang Liang asked tentatively.

Jiang Cheng shook his head, "Later, you guys are now on the right track, you don't need me to guide anything, the R&D team also has it, to use their intelligence, it is impossible to count on me for everything."

Zhang Liang knew that the 64-layer structure of Dajiang Storage was perfected under Jiang Cheng's guidance, and his SSD suddenly reached 128GB, keeping up with the international mainstream level.

So at this time, I can't wait for Jiang Cheng to guide him, but Jiang Cheng doesn't have so much energy to fix so many things.

However, after hanging up Zhang Liang's phone, another piece of good news came.
