Li Wei felt that he was losing money.

But it seems that it is not a loss.

After an hour of study, he obtained the technology of high-end commercial chips, but in fact... he didn't get it completely.

The "next year" high-end chip manufacturing technology that can be obtained by learning in the library once is not commercially available for 3 nanometers, but it is still commercially available for 5 nanometers, but the manufacturing cost has decreased and the technology is diverse.

There are not only photolithography methods, but also micro-photocopying, extreme etching, water engraving and printing.

Needless to say, lithography is the mainstream method used by humans at present. Although the technology deduced by the Time Library can avoid human patent routes, Li Future discovered many disadvantages of lithography, so he chose printing technology after choosing.

Printing, this technology is very familiar to people from Fanxing Country. It is one of the four great inventions of Fanxing in ancient times.

Unexpectedly, this ancient technology can be developed to the point of printing nanochips, and because of its characteristics, it can also print flexible chips.

The printing technology given by the Time Library is an electronic manufacturing technology based on the printing principle. In short, it is "printing + electronics", which uses precision printing technology to make electronic devices or circuits.

Change the ink that expresses the color to ink with electronic functions, and the printed graphics have electronic functions.

Various electronic devices commonly found in daily life, the integrated circuit chip ICs are achieved through a series of processing steps such as complex lithography, development, and etching. They also make a functional material into a graphic structure on a planar substrate. The traditional integrated circuit chip processing method requires 8 steps from coating to glue removal, while printing processing only requires two steps.

Precision printing methods can directly deposit functional materials onto the substrate surface in a pattern, requiring only an additional sintering process to sinter the "ink" material into a solid material, forming the same graphic structure as that required 8 steps for traditional processes to achieve.

Unlike the "subtraction" of lithography, printing electronics technology is essentially an additive "addition" manufacturing technology, so printing can deposit functional materials on the surface of any material, such as plastic, paper, fabric, and other large amounts of low-cost flexible materials.

Moreover, according to information prompts, printing technology can continue to be used in more precise graphene chip manufacturing.

In the technical context of the Time Library, 5 nanometers are the masterpiece of silicon-based chips, and 3 nanometers directly use carbon-based materials.

The reason why Li Future knew something other than these manufacturing technologies was that the chip printing technology he obtained today was more similar to the "general outline" rather than the specific manufacturing technology.

To get a nanoprinter, he had to continue learning other technologies and then assemble the nanoprinter with the parts made by those technologies.

Just like he is building mobile phones now, he starts with other technologies and then manufactures parts to assemble them into new mobile phones.

However, because the current mainstream world is lithography technology, the development of printing technology is not good. If you want to make equipment that can print 5nm chips, Li must learn a large number of related technologies in the future and then improve the technology of the entire industrial chain.

This is different from the plan he thought of before to exchange for "air tickets" for "one day". Not only did he get the technology without getting it, it seemed that it was even more difficult, so he felt that he was losing money.

However, the lithography technology he first looked at was good. Although it had many limitations, it was very suitable for the current situation.

Lithography technology is not only the mainstream internationally, but also has a mature industrial chain here, but it is just that it cannot manufacture top lithography machines.

According to the shortcomings of the "barrel theory", Fanxing can make 28-nanometer domestic lithography machines, while half of the longer boards are 14-nanometers, and the longest one has touched 5-nanometers.

Therefore, if Li Lian wanted to use a lithography machine to match the bridge, it only took a few "days" to get the full 5nm technology soon.

And with Fanxing's related industrial heritage, those technologies can be quickly digested, and perhaps people can use domestic 5nm chips next year.

With the support of 5-nanometer chips, Li can also feel at ease to build a nanoprinting industry chain.

After all, 3 nanometers are not that easy to mass produce, so 5 nanometers will definitely be active in the mobile device field for a long time.

Just like 5 nanometers have appeared now, but due to the immaturity of technology, 7 nanometers are still the mainstay of the mobile terminal.

In other fields, chips above 10 nanometers are everywhere.

From this perspective, Li Wei felt that he had no loss today.

Thinking about the chip manufacturing technology at noon, he returned to the R&D department in a daze.

Compared with complex lithography machines, it is much easier to manufacture mobile phones with "off-the-shelf" technology support.

Moreover, as a technology provider, he basically doesn’t need to worry about the remaining technical integration. At most, he just gives some advice from the perspective of students.

So most of the time, he always typing codes in an office.

He took out the things in his schoolbag after he got home in the evening, and there was the damaged tablet.

He searched at home, and finally removed a decorative picture frame with glass, then installed the damaged tablet and hung it back on the wall.

On the second day, he used a study to get the light source technology of high-end lithography machines, which added the related technologies of high-end lithography machines to the learning plan.

After two busy working hours passed, he returned to school on Sunday night. When he compared the two sides, he still liked the atmosphere of the school.

After getting the golden finger, although he had the ambition to change the world, a better life is his true yearning.

I have golden fingers and are so busy as if I am a gyro, so why not not have golden fingers?

However, he has just received the gold finger less than a month ago, and the freshness has not passed yet, and the benefits he has received from the gold finger are constantly being fed back. He feels pretty good.

However, the future development strategy must be slightly changed, and it is changed to "I want to change the world happily."

So his previous rental considerations were invalid, and it would be great to continue living with five sand sculptures in the dormitory.

As for typing codes, then go to the library. No one disturbs me when typing codes in my personal training room.

Li didn't read the private message in the next two days, but the company's handling was very good, just saying that the current technology is not perfect, so it is not convenient to disclose too much information.

Most of the game companies did not make any noise in this reply, but what surprised him was that Haha, the game was in contact, and even had a lot of chatting with the customer service, and often posted emoticons.

Good guy, haha, are the staff on the game so silly?

But in the same way, he became interested.

He wanted to talk to the other party.

Of course, he had to make some preparations before that, such as asking Ma De, the "Game Understanding" in the dormitory, to see if he knew some of the situations in the game.

This weekend, except for Li Wei suddenly returned home, the other five people were all staying in school, but basically Ma De and Zhang Chi were in the dormitory, and the other three were unable to find anyone as usual.

The two basketball teams are either playing basketball or training. If the prince is not accompanying his girlfriend, then there is a high probability that he will follow the old driver of the photography club to take pictures of the girls.

Ma De and Zhang Chi also experienced the fun of parallel worlds. The former has been converting the previous Fantasy 4 game data into parallel worlds, while the latter is working hard to create the next short film.

At the same time, they have been contacting friends and friends, constantly filling in materials for parallel worlds.

Seeing Li Wei come in with his schoolbag on his back, Ma De first saw it. He yelled: "Damn, Brother Li, you are back. You haven't read comments these two days. Your fans are all hungry and are still urging your millions of fans to benefit, so... when will the next video be released?"

Li Wei put down his schoolbag and rubbed his dog's head, then sat down in his seat and turned on the computer and said, "I think you can't wait to watch the next video, what other fans are there."

"Hey, Brother Li, you are unreasonable now. Can't I be your fan?"

As Ma De said that, he opened his homepage of his beep station and pointed to the [recent coin-operated video] below to show Li Wei: "Look, I'll give you three consecutive games every time!"

When Li Wei saw that it was true, he said, "Okay, for your sake, I will make a new video tomorrow, okay?"

"It's indeed a good brother!" Ma De immediately gave a thumbs up.

Li Wei smiled and shook his head, then seemed to remember something, turned his head and said to him, "By the way, Brother De, you haven't bought a new phone yet, right?"

"Talking about the machine..."

Ma De was about to continue to talk, but then realized that the point was not the point, so he changed his words: "Uh, yes, I haven't bought it yet, because I still don't know what to buy, what's wrong?"

"That's fine."

Li Wei nodded and leaned back on the chair, leaned back tactically and said, "Should you wait a few months, and by September, there will definitely be a phone that will make you excited."
Chapter completed!
