In fact, I have been doing the layout of the chip industry for a long time. Although I also admit that our country's chip semiconductor technology is not as good as the Mi Federation at the moment. But it's not as bad as you think.

I'll have good news for you! Our I light source projection domestic lithography machine has completed a technological breakthrough. Theoretically, it is already possible to manufacture chips within 380 to 350 nanometers. More importantly, our own logic processor chip has also been designed, as long as the domestic lithography machine is in place, we will be able to produce our own chip immediately. ”

The crowd was of course stunned when they heard this.

Longhan Technology can produce its own processor chips.

Really?

This happiness came too suddenly!

Wei Hongye hurriedly said: "Mr. Su, is what you said true?" ”

Su Han said: "Of course it's true. Am I the kind of person who likes to joke! By the way, Director Jin, the chip factory I built in Modu has been completed. You go and organize a team of elite soldiers. I have now ordered a pilot production line for chips, which will be assembled and then trial-produced in the near future. You go to the chip production plant in Modu, go there to organize the organization, prepare the test workshop, and install it as soon as the things are in place. We must seize the time to debug the equipment, and we must produce our own chips in a short time. This time, we must let the guys in the Mi Federation see that the west is not bright and the east is bright, and everyone on this earth will turn the same way.

A certain country doesn't let us use their chips, so we make our own chips.

This time, people all over the world must know that when it comes to computers, the hardware level of Longhan Technology is also as strong. ”

Jin Mengfan hurriedly patted his chest and took the military order.

The heads of other administrative departments were also envious.

Nine times out of ten, Jin Mengfan will be a local magistrate.

The administrative leader of the first chip production plant in China is also awesome to think about.

Su Han looked at the crowd: "Everyone is doing step by step, what should be done, and what else should be done." Don't talk nonsense about the chips, when the time comes, let's use our own chips, and look at what the guys in the Mi Federation are talking about. ”

Imagine the Chinese network

When everyone heard this, the blood bar was suddenly resurrected with full blood again.

One by one, they are no longer as weak as before.

They all want to fight this turnaround battle.

……

After the meeting.

Jin Mengfan took a group of cronies to the chip production plant in the magic capital.

The chip production plant, which has been built for more than half a year, has been doing air quality tests repeatedly because it has no equipment.

After all, chip production requires a dust-free environment, and the requirements for air quality are still very high.

After Jin Mengfan led the team to arrive, he hurriedly organized personnel to prepare for the arrival of the equipment.

……

A week later.

The first batch of lithography machines, packaging machines, ion implanters and other equipment for testing have arrived at the factory to start installation.

The most important functions of a lithography machine are the light source and the exposure process.

The reason why the domestic lithography machine didn't work before was that the light source technology was obviously lagging behind, and of course, the exposure process was not good.

In fact, the chip production equipment with the largest output in the international market generally uses the technology of the first generation of G light source from about 1.5 microns to 800 nanometers.

After all, not all chips require high-end chip manufacturing within 350 nanometers.

The second-generation I light source is mainly used for chip manufacturing around 365 nanometers.

However, the third generation of light sources, deep ultraviolet light (DUV), is already available.

It's just that it's not very stable yet, and it won't be able to form a production capacity.

And the fourth-generation light source technology, extreme ultraviolet light (EUV), is now unknown to everyone.

Almost all areas of lithography machine manufacturing in the world are stuck in this place.

Although chip production has tried to move closer to the third generation of light sources.

But the mass-produced ones are actually still around the second generation.

Intel's Pentium series and AM's K series are both mass-produced products of second-generation light sources.

In the global lithography machine market, in fact, the second generation of light source technology is still in the bank.

Speaking of the level of lithography machine manufacturing at this point in time.

It is dominated by two brands from the Long Island nation.

The domestic lithography machine that Su Han said was still at the level of the first generation before.

After talking about the light source, let's talk about the exposure process.

After all, the light source and the production process are indispensable.

There are three types of lithography exposure processes today.

The first type of proximity exposure.

The second type of contact exposure.

The third type of projection exposure.

Contact exposure accuracy is high.

However, contact exposure requires contact with wafers, which is easy to cause damage to wafers and masks, with low yield and high cost, which is not suitable for large-scale production.

Now it's almost unused.

Proximity exposure, although it does not touch the wafer, there is no damage, and the yield rate is also high. However, proximity exposure also has its own problems, that is, there is the problem of light diffraction, and the resolution of light after diffraction is low. If you want to improve the yield, you can only lose resolution.

The accuracy of the chip in the production department is too poor, and naturally no one uses it.

Projection exposure uses a lens to focus light between the mask and the photoresist to increase resolution.

Therefore, the projection exposure process is the main process of chip processing at present.

However, projection exposure is only the general direction.

There are also different branches of processing below.

Such as progressive, sweeping, off-axis coaxial, etc......

In fact, the difficulty of chip manufacturing lies in these processing technologies.

Different processing technologies represent different production speeds and yields.

Productivity is not the same.

The light source technology before the domestic lithography machine is still at the level of a generation.

Although the exposure process is also projectional, the exposure process is backward, and the production speed and efficiency are not good.

The breakthrough that Su Han said is divided into three levels, one is the breakthrough in the light source, the other is the breakthrough in the exposure process, and the breakthrough in various production materials.

The previous domestic lithography machine was a generation of G light source.

After more than a year of hard research and development.

Finally broke through to the second generation I light source.

After all, the light source technology of this lithography machine is not as perverted as it will be in the future.

As long as the money is in place, it is still possible to break through.

The main restriction on chip production is the process flow of projection exposure.

Su Han doesn't know much about lithography machines, but he knows a lot of chip design drawings, and in fact, from these drawings, he can deduce what the other party's process sequence is.

After all, he is proficient in chip design, but not in equipment production and manufacturing.

However, with the process sequence, at least there is an answer to the mold lake.

Although the answers cannot be guaranteed to be 100% accurate.

But Su Han didn't want to answer 100% accurately.

100% accurate, isn't it plagiarizing someone else?

This can easily lead to intellectual property disputes.

Su Han just gave the lithography machine production team a process idea, and the rest asked the lithography machine production team to figure out their own way.
