My Super Black Technology Empire

"Little Liu, what are you doing all this fuss about? Only 800 million orders. Didn't SMIC place us an order of 1.7 billion?

Wait, what are you talking about? Who placed the order for us? "At this time, the sales department manager on night shift, probably in his thirties and a little blessed, walked over with a thermos cup.

"Manager, it is Datang Technology who placed the order for us! It is Datang Technology!" Xiao Liu quickly took the manager to his computer and pointed to one of the messages.

"Fuck, Datang Technology? Do I remember that they are not engaged in heavy industry? The emerging technology companies that have been hot in the past two days, they also want to engage in chips?

This...this is illogical. "At this time, the manager of the sales department was also taken aback, and then immediately reported the news to the senior management who was still sleeping.

Of course, he just sent a message to briefly explain the situation. He didn't dare to take this risk after making a phone call in the middle of the night.

"Where do they have the ability to produce chips? The lithography machine came out?" At this time, Xiao Liu was also a little skeptical about his life. A heavy industry worker came to make chips?

Isn't this a joke?

"What order did they place? The etched list?"

"Yes, they placed an order for one million wafers from several other fabs, and then sent them to us, let us complete a series of steps such as etching in the fastest time.

Then send the etched wafer to Datang Technology. Xiao Liu glanced at the data on the order and said to the manager.

"This way, we are only engaged in supply chain anyway, no matter what he does, after all, this year's economic downturn, it is estimated that the chairman will be happy after knowing it." The manager of the sales department also said.

In fact, most people think that the production of chips is just to use a lithography machine on the cut wafers, and use a laser to lay the transistors on the wafers in a certain arrangement according to the plan given by the chip design company. The chip is built like this.

In fact, this is just some self-media for traffic, which greatly simplified the process of chip production and advocated the lithography machine.

The lithography machine uses a laser to strike the transistor on the wafer, which is only the last installation step. Before this, the wafer needs to be etched, which is the so-called "grooving and foundation".

If a lithography machine is installed, the "foundation" must be completed by an etching machine.

Under normal circumstances, after a batch of sand is refined and turned into wafers, it can be etched in the chip factory, and then to the final photoetching machine.

But after all, the domestic chip industry started very slowly. Generally, these tasks are divided into major companies to complete. For example, the manufacturing of wafers is a company, and the etching is another company. The transistor is printed on with a lithography machine. Another company.

And these companies form a fragile supply chain. As long as the process of one of the links does not meet the standard, the level of the entire chip cannot be improved.

No matter how new your lithography machine is, how many nanometer transistors you can put on the wafer, as long as the process of my etching machine can't break through, I can only make you a 45-nanometer pit, then your lithography Even if the machine reaches 5 nanometers, it is useless, because it can't be installed at all.

Therefore, the backwardness of the domestic chip industry is not only the backwardness of the lithography machine, but also the backwardness of the current domestic supply chain system.

As long as one supplier loses the chain, then the entire supply chain is waiting to stop. No matter how high-end manufacturing process is, you can either go to other foundries or wait for technological breakthroughs.

Therefore, the lithography machine and the etching machine are essentially different.

The photolithography machine is used for exposure and development. The silicon wafer is covered with a layer of photoresist, and then a mask is placed on it. The mask is patterned.

Through exposure and development (similar to the principle of previous photographic film), the pattern is left on the photoresist. Then proceed to the subsequent steps (etch, impnt, etc.).

The etching machine is used to etch the silicon wafer, such as carving a groove, digging a deep pit, etc.

On their side, China Micro Technology is responsible for digging holes in the wafer.

"Manager, you said that Datang Technology is engaged in such a large order, will they have mastered any chip-related technology?" Xiao Liu asked.

"I don't think there is any hope. He placed an order for 22 nanometers. At present, there are no 22 nanometer lithography machines in our country. Generally, TSMC can place such orders.

Or other chip foundries, our orders are still mostly 90 nanometers. "The manager also shook his head, and then denied Xiao Liu's words.

"Then what does he place such a large order for? It's 800 million. We can't let us stop installing transistors after we finish etching. Let's leave it in Datang Technology's warehouse. What is his plan?" Xiao Liu was also increasingly confused at this time.

"Maybe people also have their own ideas. After all, the chip industry can't break through with enthusiasm. Although Datang Technology is a good company,

But in the chip industry, with all due respect, they will be killed. "The sales manager shook his head, and then said, "But anyway,

It is also our industry in China. Our chip industry has been stuck in the neck for nearly 30 years. I also hope that miracles will happen, but reality is reality, right? "

Don't look at them Zhongwei Technology is engaged in the wafer etching step, but in fact, they are only engaged in the last process of the etching step, which is the least technical one.

Generally speaking, the step of etching sounds like digging a hole, and it has no technical content.

After all, who can't dig pits?

Many people think so ~www.NovelMTL.com~ But it is difficult for you to dig a pit smaller than a virus.

From the beginning of the etching of the PN section, a Poly requires 32 processes, followed by Spacer, Sti, Canti, and then the copper area with the least technical content.

In fact, what their company does is the copper area with the least technical content. The last one in it is just etching. After etching, there are Pvd, ion implantation, wet method, etc.

But just like this, 90% of their company's equipment is imported, and what they do is the one with the least technical content, and only they can do the one with the least technical content in China.

It's really annoying.

"Although reality is reality, manager, do you think Datang Technology will have miracles? It's like the "Top of the Gods" we play every day." Xiao Liu asked.

"It's hard to say a miracle, but it can only be hope. For the rest, let time verify." The manager also chuckled and said.
