My Super Black Technology Empire

"Liu, what are you making a fuss about? It's only an order of 800 million yuan. Didn't SMIC just place an order of 1.7 billion yuan for us?

Wait, what did you say? Who placed the order for us? "At this time, the manager of the sales department on the night shift, probably in his thirties, who was a little fat, also came over with a thermos cup.

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

"Damn it, Datang Technology? Do I remember that they are not engaged in heavy industry? The emerging technology companies that have been very popular these days, they also want to engage in chips?

This...it's illogical. "At this time, the manager of the sales department was also stunned, 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 calling in the middle of the night.

"Where did they get the ability to produce chips? Did the lithography machine come out?" At this time, Xiao Liu was also a little skeptical about his life. A heavy industry man came to make chips?

Isn't this a joke.

"What order did they place? Etched order?"

"Yeah, they placed an order for one million wafers from several other fabs, and then sent them to us, allowing us to 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.

"Like this, we're just a supply chain guy anyway, no matter what he does, after all, the economy is sluggish these days, and it is estimated that the chairman will be happy when he finds out." 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 wafer, and use a laser to "hit" the transistors on the wafer in a certain arrangement according to the plan given by the chip design company. That's how the chip is built.

In fact, this is just some self-media for traffic, which greatly simplifies the process of chip production and trumpets lithography machines.

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

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

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

However, the domestic chip industry started very slowly after all. Generally, these tasks are divided into major companies to complete. For example, manufacturing wafers is a company, etching is another company, and lithography machines are used to make transistors. another company.

And these companies form a fragile supply chain. As long as the process of one of the links is not up to standard, the level of the entire chip will not rise.

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

Therefore, the backwardness of the domestic chip industry is not only the backwardness of the lithography machine in the true sense, but also represents the backwardness of the entire domestic supply chain system.

As long as one supplier loses the chain, the entire supply chain will wait for a break, and even the high-end manufacturing process will not be able to get up. Either go to another foundry, or just wait for a technological breakthrough.

Therefore, there is an essential difference between a lithography machine and an etching machine.

The lithography 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 on the silicon wafer, such as carving a groove, digging a deep pit, etc.

And on their side, China Micro Technology, is responsible for digging holes in the wafers.

"Manager, you said that Datang Technology has made such a large order, will they have any other chip-related technologies?" Xiao Liu asked.

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

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

"Then what did he do with such a large order? It's 800 million. We can't let us stop installing the transistors after etching, and leave them in the warehouse of Datang Technology. What is he planning?" Xiao Liu also became more and more confused at this time.

"Maybe people have their own ideas. After all, the chip industry cannot be broken through with blood. Although Datang Technology is a good company,

But in the chip industry, IMHO, they get killed off. "The sales manager shook his head and 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 a miracle will happen, but reality is reality, isn't it? "

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

Generally speaking, the steps of etching sound like digging holes, which are very unskilled.

After all, who can't dig a hole?

Many people would think so.

But it will be difficult for you to dig a hole smaller than a virus.

From the very 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 also the copper area with the least technical content, the last one, and this is just etching, and there are Pvd, ion implantation, wet method, etc. after etching.

But just like this, 90% of their company's equipment is imported, and they are the most unskilled one, and they are the only ones in China who can make this least technological one.

Really pissed off.

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

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