A big country of aerospace with black technology

"The current chip is manufactured using a 130nm process, and we want to make progress on the next generation of 90nm process chips."

A young man wearing gold-rimmed glasses stood in front of the podium and talked.

"We have to make a breakthrough in the light source system."

"Currently, there are many difficulties restricting us, but I believe that with our efforts we can achieve success."

"These difficulties will be overcome one by one!"

The man's passionate speech won the favor of most people present.

After he finished speaking, there was a roar of applause in the venue.

It makes people feel like they are in some kind of MLM scene.

"Dean, what do you think of what Professor Chen said?" Qin Ming, who was sitting next to Zhang Xingyang, looked away from the stage with a flushed face and turned to look at his leader.

Zhang Xingyang frowned and looked at the high-spirited Chen Du on the stage.

In fact, he didn't know who the speaker of the meeting was before he sat in the venue.

The only thing is, let’s take a look at what the domestic technology community currently thinks about chips.

However, after watching half of the game, he felt a little regretful for coming today.

Because he already recognized who was on the stage.

Chen Du, who had delayed domestic chips for more than ten years and almost killed them by himself.

In the 1920s, among the post-90s and post-00s generations, not so many people knew about this matter.

But many people born in the 1980s should still remember this matter.

"Hanxin Incident"!

An out-and-out self-directed farce!

A scar engraved on the spine of domestic chips!

As the protagonist of the whole incident, after being exposed, he absconded early and escaped sanctions.

Now, this person who would have been found to be a faker five years later is standing in front of Zhang Xingyang with a smile on his face.

"How do I watch? I sit and watch!"

Zhang Xingyang said in a somewhat angry and funny tone.

However, after a moment, Zhang Xingyang regained his usual calmness:

"Chip manufacturing is not that simple. If they are so blindly optimistic now, they will definitely stumble in this regard in the future."

The chip manufacturing process at this time, although in the future, will be some extremely backward products.

Even the most advanced 90nm process chips that were originally supposed to be put into production in three years are already junk goods that are not even used by household smart sweeping robots twenty years later.

However, it has to be said that mastering the development context of such technology is still very important.

Nowadays, even for 130nm process chips, how can we handle 3nm process chips in the future?

Although Zhang Xingyang is not optimistic about the blind technological optimism mentioned by Chen Du, this does not mean that Zhang Xingyang does not recognize the development of an independent chip industry in China.

However, if you take too big a step in this regard, you will easily get hurt.

"Isn't the dean optimistic about their technical plan?"

Qin Ming looked at Zhang Xingyang with some confusion and asked.

In Qin Ming's view, there is nothing wrong with the technical solution Chen Du just talked about. After all, he was a senior semiconductor engineer when he was at Motorola, so he didn't see many problems in this regard.

Zhang Xingyang was speechless when he heard this so-called technical solution, and the corners of his mouth twitched.

"It's not that I'm not optimistic about their technical solutions."

"I am not optimistic about the so-called senior semiconductor engineers."

A word game is involved here.

Although Chen Du boasts on his resume that he was a senior semiconductor engineer at Motorola.

Logically speaking, although Motorola has already shown a decline at this time, in terms of mobile phone business and chip business, it is still one of the top super companies in the world.

So if he is really a senior semiconductor engineer from Motorola, then he can be regarded as having two brushes in the entire semiconductor industry in the world.

But in later generations, his resume has long been cleared up, and he was only a senior electronic engineer at Motorola.

There is not much difference between the two in Chinese language.

But within Motorola, they are almost completely different.

A senior semiconductor engineer, he can almost be considered a leader in semiconductors.

A senior electronic engineer can at best be considered a member of the semiconductor team.

Is a senior electronic engineer considered capable?

Of course it is!

However, this is not enough to support him as the head of research and development of a chip.

This is like being able to defeat BOSS at level 30?

Of course you can, but you can only fight those at level 30, not those at level 70.

Nowadays, 130nm process chips are equivalent to level 70 BOSS.

"Senior Semiconductor Engineer, what's the problem?"

Qin Ming still asked in confusion:

"No matter how you say it, Motorola is considered the top company in the industry."

Qin Ming still hasn't been able to understand the true meaning of the words Zhang Xingyang just said.

He also thought that Zhang Xingyang was a little dissatisfied that Chen Du was not from a top scientific research institution.

Zhang Xingyang was a little speechless at first, but after thinking about it, he was relieved.

After all, Qin Ming has stayed in a research institute with a relatively good and transparent working environment for a long time, so it is normal for him to be confused about some aspects.

Zhang Xingyang actually just shouted directly in Qin Ming's ear: Chen Du is a liar, and you have all been deceived by him!

"Motorola is indeed a good company, but it may not be able to sustain it very well."

"It does not mean that the engineers who come out of it all have extremely excellent abilities and characters."

Zhang Xingyang looked at Chen Du, who was surrounded by a large group of people on the stage, and thought thoughtfully.

Motorola, which was at the height of its power in the era of feature phones, would not have imagined that ten years later, it would be reduced to selling itself at a low price.

Just like the young and energetic Chen Du on stage, he would never have thought that he would embark on a path of fraud, right?

Perhaps at this time, Chen Du still held the mentality that he could save domestic chips.

But when he encountered many obstacles and failures, and was lifted to a certain height by his fame, he finally made the decision to fake chips, perhaps out of a momentary evil thought, or perhaps after pondering for a long time.

Even Zhang Xingyang, who has a future perspective, cannot explain clearly the psychology of the person involved.

What's more, what about the people who are really living in this era?

But history is ultimately consequential.

No matter what he thought at the time, all that everyone could see afterwards was the devastation he left behind.

Therefore, the only evaluation that everyone can give him is a domestic chip sinner.

Zhang Xingyang did not expose Chen Du's carefully disguised face in front of everyone on the spot, nor did he go on stage to say anything more.

He just stood up, glanced at the high-spirited Chen Du from a distance, and muttered a few words silently in his heart.

He took Qin Ming and left the venue.

——

"So, which way do you think we should go?"

Sun Hongtao looked at Zhang Xingyang thoughtfully and asked.

Just now, Zhang Xingyang told the whole story of the "Hanxin incident" that he learned about, and hoped that Mr. Sun would pay attention to this matter.

However, Sun Hongtao did not dwell too much on Chen Du, but instead paid attention to Zhang Xingyang, who seemed to have many opinions on domestic chips.

In fact, Sun Hongtao's ideas are relatively easy to understand.

In industries heavily subsidized by the state, it is difficult not to see various forms of subsidy fraud.

It's like piles of fertilizer spread over a field.

Will only crops grow?

No, batches of weeds will definitely grow at the same time.

But can you not fertilize because of the possibility of weeds growing in the future?

Wouldn't that mean that we really stopped eating because of choking?

What the country can do is to get rid of the weeds that compete with the crops for nutrients amid the tide, patiently care for the crops that are still in the seedling stage, and wait for the day when they grow.

"Let's not talk about the problems of domestic chip design."

Zhang Xingyang did not talk about design issues, but directly talked about manufacturing:

"When it comes to chip production alone, almost all of our current lithography equipment is imported from abroad."

"Once someone imposes sanctions on us in this regard, the consequences will be self-evident."

The situation Zhang Xingyang mentioned will not actually happen in the past ten years. It will not happen until more than ten years later.

However, that will only happen after domestic mobile phones have gained their own place in the world's mobile phone shipments.

At present, independent domestically produced mobile phones have not yet developed, so naturally there are no worries in this regard.

After hearing Zhang Xingyang's words, Sun Hongtao's eyes darkened.

Everyone says that it is unnecessary that China still retains almost the most complete industrial categories in the world.

However, how do those people know why these seemingly unnecessary industrial categories are still retained in the country?

Isn't it just that in the past years, I was afraid of being sanctioned.

So, no matter what others say, you must maintain your own strength in these aspects!

Because of this, Sun Hongtao, an old man who seemed to be unable to keep up with the development of the times, was able to understand what Zhang Xingyang meant.

"But we are still almost blank in this area, and it is very difficult to develop again!"

Sun Hongtao said in a hoarse voice after being silent for a few minutes.

"We also organized technical demonstrations, but gave up in the end."

"The current domestic technology reserves are still unable to meet its research and development conditions."

Lithography equipment is known as the crown jewel of industry.

Although decades later, this industrial crown and the pearl on it are basically worn on the heads of the country.

But at this time, China can only hold pearls in some specific fields, and most of the pearls are still in the hands of countries with advanced technology.

“Actually, the light source equipment is the most stuck in current lithography equipment in China.”

After Zhang Xingyang thought about it for a while, he still told Mr. Sun about the difficulties of photolithography equipment.

"You should also know that a photolithography machine, as its name implies, uses lasers to perform laser operations on silicon wafers to form complex integrated circuits."

“In this process, a protective film of photoresist must first be attached to the surface of the wafer, and then an ultraviolet laser is used to remove the protective film on the surface of the wafer.”

"After using an etchant to etch the parts that have lost the protective film, an integrated circuit can be formed on the wafer."

"Here, if we want to ensure the accuracy of integrated circuits and ensure the yield of chips, the most critical thing is the light source."

When Zhang Xingyang said this, he paused for a moment and continued:

"In fact, China is not weak in ultraviolet lasers at present, but there are still certain problems in the application of light sources for lithography machines."

"We are still mainly focused on the research of deep ultraviolet light, but the key to the next generation of lithography technology is definitely extreme ultraviolet light."

"Currently, internationally, the development of extreme ultraviolet light sources is also very rapid."

“As far as I know, ASML’s LPP EUV is about to be developed.”

"They are produced by exciting Sn droplets with a 40-kilowatt infrared laser.

It's hard to say how advanced this technology is, but it's definitely in their interests. "

After all, ASML is not the same as China. They are a commercial company, and the lithography machines they produce naturally exist as commodities.

There is still a slight difference from the photolithography equipment that exists as a production tool in China.

For goods, transportation issues must be taken into consideration.

This resulted in ASML having to impose certain restrictions on the size of the device.

And now, Zhang Xingyang wants to bring a way to the country that seems to be a crooked way now.

"Mr. Sun, you should also know, what is our purpose?"

"Are we going to develop ultraviolet lasers, or are we going to have our own domestic lithography equipment?"

After Zhang Xingyang talked a lot, he asked Mr. Sun another question.

Sun Hongtao had not yet reacted at this time, and had not yet followed Zhang Xingyang's train of thought:

"What's the difference between the two?"

But while talking, Sun Hongtao also reacted:

"Could it be that?"

"Do you have a way to bypass UV lasers?"

Zhang Xingyang sighed softly:

"This method is actually a bit tricky."

"You also know that our purpose in developing lasers is to use lasers as knives to carve on wafers."

"So what we want is not a specific laser, but a sharp knife!"

"Actually, in the microscopic realm, there are sharper knives."

“We build a device similar to an undulator on the ring particle accelerator. When the accelerated electron beam passes through this device, a high-energy laser is injected from the outside.

Arrange the electron beams in the accelerator more regularly so that the radiation energy they emit becomes concentrated.

This also allows the synchrotron radiation source of the ring particle accelerator to emit a free electron laser similar to that of a linear accelerator.

In this case, this beam of light has the purity of synchrotron radiation and the high-energy characteristics of free electron lasers, and can be used in the field of lithography. "

At the end, Zhang Xingyang thought about it and added:

"But there is a small drawback."

"What flaw?"

Sun Hongtao also half understood the previous technical principles.

"The lithography equipment will be larger."

"Chip manufacturing plants need to be built around photolithography machines!"

The technical theory in this chapter comes from the SSMB-EUV solution of the Tsinghua team. There is no accurate information yet, it is just for entertainment.
