Lu An is certainly aware of these precedents that Rebus said.

GF stands for Globalfoundres, Chinese name Globalfoundres, a semiconductor manufacturing company spun off from AMD and jointly invested with ATC, an advanced technology investment company in Abu Dhabi, United Arab Emirates, and Mubadala, a development company in Mubadala.

In the 32nm process, because the frequency and voltage were too different from the design, AMD had to give up a whole generation of low-power APUs and redesign them to find TSMC foundry.

In the first generation of TSMC's 4028nm process, there were also many problems, it was very immature, and its production capacity could not keep up at all, and even affected the entire semiconductor industry.

So, this ambition of Rebus, he can understand.

Because, the mature tape-out design is delivered to the OEM, it is difficult to say that it will get twice the result with half the effort, but there will not be more problems.

Lu An can even understand that Rebus spent as much as 20 billion US dollars, plus gave up Xiaomi's 3rd and 4th generations to fully support the laboratory.

Because, mastering the core, is the real new domestic product!

It's just that Rebus and Xiaomi's executives didn't expect that the speed of mobile phone manufacturers such as OV and Huawei would be so fast.

Especially the OV of the same boss, the horror of the marketing model, the fierceness of the counterattack, it is simply fuckless.

Lu An chuckled.

"Lao Lei, I quite agree with your approach, and I blame me for not doing a good job in grasping the time, which delayed Xiaomi's time. ”

He meant that if he had given the chip to Rebus in advance, he might not have been in such a hurry now, but Rebus didn't know about it.

Rebus waved his hand and said seriously.

"You can't say that, it's Mr. Lu that makes Xiaomi hope to be independent in the core!"

If the new MU only made some of Rebus's ideas a reality, then the emergence of chips completely made this idea a reality.

What is missing now is only the polishing of time and industrial base.

What's more, Rebus knows very well that Lu An is giving knowledge, not a one-shot deal.

It is not for nothing that Xiaomi can develop to this point today, and if it is just a pile of mud, Rebus would not dare to have such ambitions.

"Let's go, the rest of the thing, said on the way. ”

Lu An just finished drinking the tea in the cup, and said while putting down the cup and getting up to his side.

Rebus: Black question mark .jpg.

What?

............

Lu An got into Rebus's car.

When he got into the car from the porch, Rebus said, "Mr. Lu worked hard. ”

The tone is very sincere.

He saw the license plate of the Bentley Bentayga parked on the side of the porch, Xiang A·99998.

It is natural to understand that this is the car that Lu An brought from Star City, and it has been very hard all the way.

Rebus's vans are likewise completely separated from the cockpit and passenger compartment, guaranteeing absolute privacy in the rear.

Lu An took the initiative to stir up the topic.

"Old Lei, let's make a decision, it's still too late to lay out. ”

Rebus looked confused again, what?

"What do you mean?"

Lu An said with a smile, "Build a new 12-inch or expected 18-inch wafer factory, starting with all the current foundations, the mainland's resources are very rich!"

Rebus subconsciously wanted to refuse, such as huge investment, such as risk, such as necessity, the thought just turned in his head, and immediately understood what Lu An meant.

The fab is not built overnight, especially if you really want to consider 18-inch 450mm wafers, the investment risk and investment amount will be very large, and the completion time will be correspondingly extended.

Now is indeed a good time to lay out the industrial chain.

If Rebus's ambition is to target Apple and the 92 percent profit that Apple exclusively owns, then these layouts are necessary.

Rebus sighed and said.

"Compared with Mr. Lu, my thinking is really a little out of step with the times, I'm getting old!"

Lu An smiled and didn't speak.

Will you be able to inflate a blow too?

Rebus laughed too.

"This matter, let me think about it again, if Xiaomi is dominant, there will be a lot of troubles, especially Xiaomi's equity, which has always been an important factor restricting the development of Xiaomi.

So, this piece of meat, take it with Huawei and other companies to eat!"

Lu An nodded, "Mr. Lei's realm is high, I didn't think about it so much." ”

He understood what Rebus meant, a company with such a strong and clear equity would indeed not reassure some people.

This is also one of the main reasons why Xiaomi will focus on the laboratory in the 3rd and 4th generations.

Huawei has HiSilicon Kirin, although it is only a factory-less semiconductor, but it cannot deny its ability in the circuit design of hardware chips.

............

Lu An groaned and said something selectively.

"Lao Lei, I really didn't know much about the things on the lithography production line before, but after you called me, I looked for information, it's okay, it's not difficult. ”

Lu An's tone was very relaxed, and Rebus also relaxed a lot.

He already has a certain immunity to Lu An's excellence in some technical fields.

MU optimization, 5G, chip design and testing, etc., etc., now it is not too much to have another lithography production line proficient.

"Thank you Mr. Lu, Mr. Lu is really thoughtful!"

This time, because it was a weekend, and I was in a hurry, Rebus's driver level was okay, so I rushed to Xiaomi's secret laboratory after an hour and ten minutes.

It's still the dilapidated factory, it's the same security checkpoint, and it's still the main body of the laboratory that doesn't know how many meters underground.

still went directly to the area of the chip department, the difference is that this time, Rebus took Lu An to turn left and right, and entered another area.

Xiaomi's 12-inch wafer factory, a 12-inch wafer factory with 3 production lines, has now opened one, and the remaining two are to be activated!

Originally, Xiaomi also considered another 16nm or 14nm this year, ready to keep up with the pace of the mainstream in one step, this time it's good, it's really in one step.

............

After entering the 7nm production workshop, what you see is the NXE3400B standing there, and the ASMLLOGO can be seen everywhere in the corresponding equipment packaging box.

After Lu An glanced at it a few times, he looked at Rebus on the side, "Old Lei, bring the engineer in charge of lithography production in the chip department here, I am short of time this time, so I won't sell it, and teach while doing it." ”

After a pause, he added.

"For the lithography production line, I only know less than 35% of the current information, just so that everyone can know the 7nm and 10nm lithography process, as for a better industrial base, we have to wait, it just so happens that Xiaomi's engineers also need time to learn!"

Rebus looked at Lu An deeply and said.

"Mr. Lu, you have really never disappointed!"

...... In the next two days, Lu An almost never left the two workshops of the 12-inch wafer fab belonging to the chip department.

The priority to start installation and commissioning is the 7nm NXE3400B and the corresponding etching and other machines.

Some people in the chip department know Lu An, and have also seen Lu An's excellence in chip testing, and this time, I saw Lu An again pinching his hands and arranging them to install the lithography production line.

Don't mention the surprise in your heart.

The evolution of their expressions is probably: Doubt, surprise, I'm afraid it's not a great god, wow, kneel down to the great god, can the great god take me, am I a staff?.gf!

NXE3400B is more important, and it is also the most expensive thing this time, Lu An is a hand-in-hand guide to install, and the initial stage of commissioning is even more personal.

He didn't know what to do to make people understand best, but he knew that it was certainly okay to teach everyone as if they were ungrounded.

In fact, the engineers in these chip departments have not touched the NXE3400B, which is almost unbasic.

After the commissioning of the 7nm production line was completed, Lu An took the engineers to debug the NXE3350B non-stop.

After a total of 63 hours, the two production lines were successfully installed and commissioned, and they were ready to be officially put into production......

At that moment, the applause was thunderous!

Today, it's late, and I'm almost cold.

Broken bowls still have to be given.

There are only two shifts. ...
