This is how black technology should be used

Chapter 23 Really?
Li Future felt that he was at a loss.

But it seems that there is no loss.

After an hour of study, he got 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 the time library in one study is not commercial 3nm, but still commercial 5nm, but the manufacturing cost has dropped, and the technology is still diverse.

Not only photolithography, but also lithography, extreme etching, water engraving and printing.

Needless to say, lithography is currently the mainstream method used by humans. Although the technology deduced by the Time Library can evade human patent routes, Li Weiwei discovered many disadvantages of lithography, so he chose printing technology.

Printing, this technology is very familiar to the people of Fanxing Country, and it is one of the four great inventions of Fanxing Ancient Times.

Unexpectedly, this ancient technology can be developed to the point of printing nano-chips, 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 printing principles. In short, it is "printing + electronics", which uses precision printing technology to make electronic devices or circuits.

Replace the ink that expresses the color with the ink that has electronic functions, and the printed graphics will have electronic functions.

Various electronic devices that are common in daily life, the integrated circuit chip IC in them is realized through a series of processing steps such as complex photolithography, development, and etching. It is also made of a functional material on a flat substrate. Graphical structure, the traditional integrated circuit chip processing method needs to go through 8 steps from coating to glue removal, while the printing process only needs two steps.

The precise printing method can directly deposit functional materials onto the surface of the substrate in a patterned manner, and only requires an additional sintering process to sinter the "ink" material into a solid material, forming the same pattern as the traditional process that requires 8 steps to achieve structure.

Different from the "subtraction" of lithography, printed electronics technology, like 3D printing, is essentially an additive "additive" manufacturing technology, so printing can deposit functional materials on the surface of any material, such as plastic, paper, cloth, etc. Low cost flexible material.

And according to the information, printing technology can continue to be used in the manufacture of more sophisticated graphene chips.

In the technical context of Time Library, 5nm is the swan song of silicon-based chips, and 3nm directly uses carbon-based materials.

The reason why Li Future knows something other than these manufacturing technologies is because the chip printing technology he has obtained today is more similar to the "general outline" rather than specific manufacturing technologies.

In order to get a nano-printing machine, he has to continue to learn other technologies, and then use the parts made by those technologies to assemble a nano-printing machine.

Just like when he makes mobile phones now, he starts from other technologies and then manufactures the parts to assemble into a new mobile phone.

However, because the current mainstream of the world is lithography technology, and the development of printing technology is not good. If he wants to manufacture equipment that can print 5nm chips, Li will have to learn a lot of related technologies in the future, and then upgrade the technology of the entire industry chain.

This is different from the "one day" exchange "ticket" plan he thought before. Not only did he not get the technology directly, but it seemed to be more difficult, so he felt that he was at a loss.

On the contrary, the lithography technology he looked at first was good. Although it has many limitations, it is very suitable for the current situation.

Lithography technology is not only the international mainstream, Fanxing also has a mature industrial chain, but it cannot manufacture top-notch lithography machines.

According to the short board of the "barrel theory", Fanxing can manufacture 28-nanometer domestic lithography machines, and half of the relatively long boards are 14-nanometer, and the longest one has touched 5 nanometers.

Therefore, if Li Future wants to use a lithography machine to make a bridge, it only takes a few "days" of work, and he will soon be able to get the full 5-nanometer technology.

And in terms of Fanxing's related industry background, it can also quickly digest those technologies, and perhaps people will be able to use domestically produced 5-nanometer chips next year.

With the backing of 5-nanometer chips, Li Future can also rest assured to build a nano-printing industry chain.

After all, 3nm is not so easy to mass produce, so 5nm will definitely be active in the field of mobile devices for a long time.

Just like the emergence of 5nm now, due to the immaturity of technology, 7nm is still the mainstay of the mobile terminal.

In other fields, chips above 10 nanometers abound.

From this point of view, Li Weiwei felt that he did not lose money today.

After thinking about the chip manufacturing technology all afternoon, he returned to the R&D department in a daze.

Compared with complex photolithography machines, mobile phone manufacturing supported by "off-the-shelf" technology is much simpler.

And as a technology provider, he basically doesn't need to ask about the rest of the technology integration. At most, he just gives some suggestions from the perspective of students.

So most of the time, he was in an office typing code.

After returning home at night, he took out the things in his schoolbag, including the damaged tablet.

He searched around the house, and finally removed a decorative picture frame with glass, then installed the damaged plate in it, and hung it on the wall again.

On the second day, he used one study to get the light source technology of the high-end lithography machine, which can be regarded as adding the related technology of the high-end lithography machine to the learning plan.

After two busy days at work, he returned to school on Sunday night. Comparing both sides, he still liked the atmosphere of the school.

After getting Golden Finger, although he has the ambition to change the world, a better life is his true yearning.

There are already golden fingers and they are as busy as a spinning top, so it’s better not to have golden fingers.

However, he just got the golden finger for less than a month, and the freshness has not passed, and the benefits he got because of the golden finger are constantly being fed back, and he feels pretty good.

It’s just that the future development strategy does need to be slightly changed to “I want to happily change the world.”

So his previous consideration of renting a house was also invalidated, and it would be good to continue living with the five sand sculptures in the dormitory.

As for those who want to type codes, then go to the library, and no one will bother you when you type codes in the personal training room.

Li didn't read the private message for the next two days, but the company handled it very well, but said that the current technology is not perfect, so it is inconvenient to disclose too much information.

With this reply, most of the game companies were silent, but what surprised him was that Haha Games kept in touch, and even chatted happily with customer service, and often sent emojis.

Good guy, are the staff at Haha Game so stupid?
But at the same time, he also became interested.

He wants to talk to each other.

Of course, before that, he had to make some preparations, such as asking the dormitory's "Game Master" Ma De to see if he knew something about Haha Game.

This weekend, except for Li Weiwei who came home suddenly, the other five people stayed in the school, but basically Ma De and Zhang Chi were in the dormitory, and the other three could not find anyone as usual.

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

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

At the same time, they have been contacting friends and colleagues, constantly filling the parallel world with material.

Seeing Li Weiwei coming in with his schoolbag on his back, Ma De saw it first, and he opened his mouth and yelled: "Damn, brother Li, you are back, you haven't read comments for the past two days, your fans are all waiting to be fed, why don't you I've been urging you for the benefits of millions of fans, so... when is the next video coming out?"

Li Weilai 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, why are you my fans?"

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

As Ma De spoke, he opened his homepage, and pointed to the [recent coin-operating video] below to show Li Weiwei: "Look, I'll give you three times in a row!"

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

"Sure enough, he is a good brother!" Ma De immediately gave a thumbs up.

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

"Speaking machine..."

Ma De just wanted to continue talking, but then realized that the point was not that, 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 Weiwei nodded and leaned back on the chair, and said tactically: "Wait a few months, wait until September, there will definitely be a mobile phone that will make your heart beat."

Ma De tilted his head in doubt: "Really?"
