"Xiao Liu, Xiao Zou, you really aren't fooling me?" As soon as Lin finished speaking, he felt a little reckless.

Because the two people in the video are from that space base.

Take Liu Chengdong as an example, he himself is the second-in-command of the base, and his position level is even higher than Lin Weiguo, the director of the optoelectronic institute.

Lin Weiguo also relied on his age and seniority to call the other party Xiao Liu.

Not to mention the other Zou Ying, who is the head of the technical department in the base, often cooperates and communicates with brother units such as the Optoelectronic Institute, and is also very familiar with each other's situations.

Take the first virtual projection watch developed and put into production, several core technologies in it are the use of the technical reserves of the Institute of Optoelectronics.

From the mouths of such two high-ranking "acquaintances" who learned about the manufacture of atomic-level precision lithography machines, Lin Weiguo's heart couldn't help but feel a little suspicious.

No way, who made the atomic-level accuracy mentioned by these two people is really a little too unbelievable!

Speaking of which, we have to briefly mention the entire process of chip manufacturing: wafer processing - oxidation - lithography - etching - thin film deposition - interconnection - testing - packaging.

One of the most critical technical steps is lithography.

What is Lithography?

To put it simply, the designed circuit pattern is "printed" onto the wafer by means of special fluctuations of light.

At present, the mainstream lithography machine on the market can be divided into two types according to the process range: one is the DUV lithography machine that refracts the 193 nanometer light source through the excimer laser.

The DUV lithography machine can basically only achieve the 25 nanometer level, such as the famous Intel company, which uses the magic modification method of double workbench to achieve the accuracy of the DUV lithography machine to 10 nanometers, but it cannot reach below 10 nanometers.

However, DUV lithography is a thing of the past, and another more advanced EUV lithography machine adopts plasma laser emission, which can emit light wave wavelengths of up to 13.5 nanometers.

In this exposure accuracy range, some advanced wafer fabs use multi-layer exposure or the superposition of multiple working platforms to greatly improve the resolution, so that the circuit accuracy level of exposure etching can be improved several times, so as to produce 7nm or even higher-level 5nm chips.

However, the result of such a tricky method is that the yield rate of the final wafer tape-out is low, which in turn leads to an exponential increase in the cost of chip manufacturing.

This is why the price of high-end chips has always remained high.

To solve this problem, it is necessary to continuously improve the exposure accuracy of the lithography machine and improve the chip manufacturing process.

So what is the concept of 0.1 nanometer precision proposed by Chen Jie?

As far as the current level of accuracy mastered by human beings, not to mention these domestic optoelectronic institutes and those semiconductor R&D companies that are halfway home, even if they are handed over to the windmill country ASML company, which is the leader of the entire industry, it will take decades or even half a century to catch up.

Once you get a lithography machine with such a level of precision, let alone any 7nm and 5nm chips, even chips with specifications and performance that are 100 or 1,000 times higher can be made in minutes.

This is why Lin Weiguo was so shocked when he heard the news, because the "satellite" on the base was too big.

……

"Lin Suo, how dare we fool you for such a major matter!"

"It's some of the classified technology involved here, and it's not quite said in the video."

"If you don't feel at ease, hurry up and bring a batch of raw materials for the manufacture of lithography machine over! The more the quantity, the better, after this village, there will be no such shop! Liu Chengdong said anxiously on the video call.

Because according to Chen Jue's attitude before, this thing may leave the base at any time because of a sudden thought.

And when Chen Jue left last time, he walked very chicly, and he couldn't stop it.

After the lesson of the last time, before he got his hands on the lithography master machine, it was impossible for Liu Chengdong to let go of his hanging heart.

Fortunately, Lin Weiguo on the other end of the video is not a pedantic person, he knows that the secret of the second home involved behind the space base is shocking enough.

On this basis, the base suddenly came up with the technology of lithography machine with atomic-level precision, and it seems to have become reasonable.

So, after confirming several times with Zou Ying and Liu Chengdong during the call, Lin Weiguo immediately mobilized the staff of the entire optoelectronic institute and sent a large number of components, raw materials, and a bunch of process materials required for the manufacture of lithography machines to the Kunpeng transport plane arranged above.

He himself also led a small team of more than a dozen people from the Optoelectronics Institute to quickly rush to the aerospace base in Long Province with this batch of materials.

……

Due to the lack of clues, the base cultural relics collection couldn't figure out how the sense of disobedience of time came about for the time being, so Chen decided to let go of the idea of continuing to think deeply.

After taking a turn in the museum, he glanced at the historical relics of various eras with traces of decay, and muttered: "Time passes and years are easy to end...... Even these dead things can't stop the erosion of time, let alone the ancient kings of flesh and blood...... Thankfully, I've taken this crucial step, and I have time to solve these mysteries......"

After saying these words that puzzled others, Chen Jue then walked out of the Tibetan Museum slowly under the surprised eyes of archaeological experts such as Liu Lao, and finally sat down on the steps at the entrance of the Tibetan Museum as if no one was there.

At this time, Liu Chengdong hurried back from a distance in a ferry, and saw that Chen Jue seemed to be squatting on the doorstep steps of an old farmer in the countryside to pass the time, and he did not look like he was leaving immediately, and he was also secretly relieved in his heart.

"Boss, in another half an hour, the materials for the lithography machine manufactured by the photoelectric institute will be delivered, and this time it seems that I will have to trouble you again." Liu Chengdong also sat down next to Chen Duxi as he spoke.

"Making chips is a fantasy for ordinary people, but for me, it's just a gesture, so you don't have to be too polite." Chen Jue waved his hand and replied disappreciatively, and by the way, he played with the smart watch, and quickly projected and flipped through the relevant process data about chip manufacturing included in the base's qualifications database.

After seeing Chen Jie's unbelievable reading speed, Liu Chengdong, who was sitting on the side, was also a little stunned.

Boy!

This speed can't be said to be ten lines at a glance, directly at a glance and a page.

If those college students outside have this reading speed and memory ability, what kind of English level 4 or 6 will not be like playing for graduate school or doctoral studies.

Chen Jue ignored the other party's surprise, and after concentrating on scanning the chip manufacturing process, he reached out and poked the ground, as if he was grabbing tofu, and pulled a palm-sized cement slab into the palm of his hand.

"Let's try wafer processing first!"

The update is coming, so everyone has been waiting for a long time~ This week is a bit of a rush and has no time and energy to update, after all, it is the first time to be a father, and a novice father has little experience on the road (covering his face)

In the middle of the night, I took the time to code a chapter~ I finally have time to update, and then strive to take care of my wife with a baby and update it stably at the same time!
