The Return of the Black Technology of Immortal World

Apparently, even Zhao Yuxi did not have the experience of entertaining so many people at once. They were busy for a while, and finally gave everyone a bottle of water.

Even though it is immoral to give people cold water in such a cold weather, no one expected that so many people would come to Weihua at once.

Including Zhao Yuxi and Zhao Manqing, there are no more than ten people in the entire comprehensive laboratory, including security guards. It is okay for each person to give a bottle of water. If it is for tea, there is not even enough kettle.

After all, Yang Qing didn't need to explain these things, but looking at Zhao Yuxi's figure busy in and out of thin clothes, Yang Qing couldn't help but feel a little guilty.

"Mr. Xu, since we're here, let's go to the workshop to have a look first. After watching the chip production, let's talk about other things."

Yang Qing said to Xu Hai who just sat down and was not ready to say anything.

"Well, let's go and have a look first!"

Yang Qing stood up and led the group of technicians, who couldn't even sit still, towards the clean room.

Although no one else had entered or exited the clean room except Yang Qing during this time, there were still enough dustproof suits, and there were more than 60 sets besides those worn by him and the robot.

These people from Weihua have already gotten used to the workflow of the clean room. While Yang Qing and Xu Hai walked in, they also changed into dust-proof clothes, put on anti-static ankle rings, and walked in one after another. .

Everyone present, except for Zhao Yuxi, is no stranger to the process of the lithography production line. Among them, some HiSilicon staff were fortunate enough to participate in the debugging of the 5-nanometer production line of TSMC when producing Kirin chips.

To be honest, no matter from which aspect, the lithography machine production line standing in front of them is not glamorous, and the appearance has long been unable to see the original 90-nanometer lithography machine because of repeated modifications.

It was originally a second-hand product, and Yang Qing is a person who only pays attention to the actual effect and does not care about the appearance. The appearance of the lithography machine has also been patched with many patches. Probably the only advantage is that it is wiped clean so that it will not be dilapidated. degree.

"Can it be turned on?" Yang Qing asked.

"Please!" Xu Hai stretched out his hand to signal.

Yang Qing lightly pressed a button, and an embedded screen next to it lit up.

During device self-test,

Self-test passed,

Check the stock of raw materials,

There are a series of dazzling data such as the number of silicon wafers, the content of photoresist, high-purity hydrogen fluoride, etc., and the storage status of the silver ion solvent of the silver interconnection.

Yang Qing confirmed the data one by one, and the data began to flow until the end.

The last screen shows that the reserve is normal,

Please enter the model and quantity of the chips produced.

Then, the cursor stopped behind the model number, and there was only one option, and Yang Qing had no choice, so he clicked on Xinlan No.1.

For the quantity, Yang Qing directly entered a one, which represented the photolithography of an eight-inch silicon wafer.

The writing on the screen disappeared, and the situation inside the photolithography machine appeared.

In fact, a deep ultraviolet excimer laser with invisible light is used, and it is completely impossible to see how the lithography machine works here. Everyone here is lonely.

However, the specific steps can still be clearly seen. The wafer was pushed onto the workbench. Since the raw materials had already been polished, Yang Qing directly ignored this step. After drying, the photoresist spin-coating began.

After spin coating, photolithography starts, and after multiple multi-directional exposures, it enters the following process.

By this time, it was completely invisible, and when we saw it again, it was the packaged chip at the end of the production line.

In the entire workshop, a total of thirty-six people listened to the slight sound and vibration coming from the lithography line, and did not dare to make a sound. They listened for nearly an hour until the chips were pushed out at the back. .

"This is Xinlan No. 1!"

Yang Qing held a chip and handed it to Xu Hai.

Xu Hai took the chip with some excitement, and looked at it carefully over and over again.

The logo on the new blue one is very simple, just write the name of the new blue one, the main frequency, and the production date.

"Mr. Xu, go and test it first." Yang Qing reminded.

Finally, the test equipment here is relatively complete, and it is not really necessary for Xu Hai to do it. Hurray, several people have squeezed around, took the chip from Yang Qing, ran to the equipment, and started testing.

These test equipments are actually from Weihua. The pilot test line is an old line, but the test equipment is indeed brand new, and it is also the same as the latest model of Weihua. There is no problem of being unable to use it.

"Same as the results of our home tests, it can be used as a processor for the next generation of mobile phones!"

"This data is stronger than Banana's M1. It's a pity to use it on mobile phones. It's just on our notebooks and tablets."

The test results came out soon, and a group of people stared at the results and made various discussions. The quiet dust-free workshop soon turned into a noisy vegetable market.

Such a result had been expected for a long time, the leaders on both sides did not approach, just stood aside, Xu Hai looked at Yang Qing with more and more complicated eyes.

Can it be uncomplicated? A person, a mere person, it is said that he only started to enter the pilot test line a few months ago to carry out the transformation of the photolithography line.

Well, if a person knows mathematics, it is a talent. Knowing software, for a mathematician, there is nothing to boast about. Even if he makes a software that can change the world, there is no mathematical theory he put forward The shock came.

But this person, who knows how to design chips and how to modify a lithography machine, is no longer a human being, is he a monster?

If it weren't for Yang Qing's mediocre student days, he really thought he had met someone he knew from birth.

But this legend seems to have just begun, making people have to wonder what kind of adventure he has.

Or just like Weihua's internal propaganda, he has obtained alien black technology, or else his mathematical theory, how can it not have much connection with the blue star?

As if without any foundation, the theory of dimensional space appeared directly, like a castle in the air, as if it would fall from the sky at any time.

Its logic is very self-consistent, even if no one can continue to deduce it, it does not mean that this theory is wrong, because no one can falsify it.

The chip is the same this time. Who doesn't know that chip stacking and improved architecture can greatly improve the performance of the chip, but who can propose this architecture and guarantee it to surpass most similar chips on the market?

The reduced instruction set processors of the year had a large number of instruction set architectures, but their performance was not as good as ARM, so they were eliminated. In recent years, there is only one risc-v architecture chip for small devices, which is compatible with ARM. Differentiated competition, but it has not yet been officially commercialized.
