Chapter 847： Catch up (below)

The 90-nm process is already the strongest production technology on the market today.

Although everyone knows Intel's virtues, it must be the sales generation, the reserve generation, and the research and development generation. They must have more advanced technology than the 90-nanometer process. However, no matter how leap-breaking it is, it is impossible to jump from The ninety-nanometer process is exaggerated to forty-five nanometers.

According to the understanding of the chief engineer, Intel's next-generation Xeon chip should be manufactured between 70 nanometers and 65 nanometers. The specific data is unclear, but the scope is generally clear.

The new technology being developed may fall around 50 nanometers.

Guo Tai came up and suddenly asked to test the 45 nanometer process?

Although the design of the lithography machine was designed according to the technical limit, this is the result that can only be achieved under ideal conditions.

In essence, as a machine, there must be manufacturing tolerances. There is no way to do this.

No matter how perfect the design is, it is impossible to achieve zero tolerance.

According to calculations in the design, if this lithography machine can be flawless, the process should be around forty nanometers.

However, if you add a nanometer error in part processing, and add a nanometer assembly error in assembly, countless parts are combined, and I am afraid that the error will definitely exceed tens of nanometers.

Ninety nanometers are already very surprising. This is already the world's advanced level, which means that the country has been able to catch up with the world's cutting-edge technology. The next thing to do is to attack the capacity of mass production and make this lithography machine as fast as possible Probably stable production.

The Chief Division knows better than anyone. Although most of the civilian chips have now been unsealed from China, a series of special-purpose chips such as military chips and some much-needed domestic communications encryption are still not available.

With the ability to mass-produce lithography machines, it means that people will never be stuck on the chip in China anymore. What a wonderful thing?

The current test results have made the chief designer extremely satisfied, but Guo Tailai is still shaking his head?

Still forty-five nanometers?

is it possible?

"Try it!"

Guo Tai smiled calmly: "What if it succeeds?

If it is unsuccessful, what effect does it have on us?

The design has been designed, and the samples have been created. It is nothing more than a waste of silicon wafers and other materials, wasting some time and electricity. Anyway, I always try, right? "

The 90-nm process has already satisfied many people, and almost everyone in the project team is cheering to illustrate this point.

But this does not mean that this sample lithography machine has only this accuracy, and everyone will always reduce the size one by one and test it again and again.

Guo Tailai's request is actually just an extremely high standard for testing. If 80 nanometers and 70 nanometers are tested one by one, it will always be their turn.

Of course, it is also possible that the test failed at 60 nanometers or 50 nanometers, and 45 nanometers will definitely not be considered.

However, the one-step test seems to waste only some materials and time, and there is really no great loss. As Guo Tailai said, try it! "Then ... try!"

The head teacher also looked forward and said with a gritted tooth, but there was an unshakable light in his eyes.

When the chief immediately told the controller who controlled the lithography machine, everyone saw a surprised expression that the controller couldn't suppress.

As if he hadn't heard the commander's words clearly, the controller repeatedly asked again, until the commander nodded with affirmation, and then began to operate the input data in shock.

"Next, we try to tape out forty-five nanometers."

The head teacher did not let everyone wait too long, and quickly announced the answer: "Everyone is ready, start in ten minutes!"

A group of white coats were frightened by the commander's words. It was only after the commander reminded them again that everyone started to wake up in a dream.

Preparing materials. Preparing materials, starting the machine and starting the machine, was in a hurry.

Guo Tailai just said, but he didn't do it.

This is someone else's design. Guo Tailai is at best just a fabrication assembler, and he should not and cannot be the leader.

The suggestion I just made is the maximum interference, and he is not suitable to intervene in any of the work later, as long as he looks at it honestly and waits for the test results.

Although everyone was shocked, everyone was professional.

It's just a test, how to feed, how to package all these methodically.

Even if this is the first prototype, but the machine itself was designed by their project team, and they have been familiar with it for two days during the previous system test and are very skilled in operation.

Watching the silicon wafer enter from the entrance, a series of operations inside the lithography machine, followed by stable cutting and packaging, and finally the packaged finished product.

There were no alarm errors during the entire process. All the steps seemed normal, and the appearance of the packaged chip seemed to be very normal, but I didn't know if it could be used normally.

A part of the unpackaged chip was removed, and the circuit size was directly observed with a microscope to determine the process size.

The packaged chip is tested in accordance with the standard test procedure. It is actually very simple to put it plainly, plug it directly into a test circuit board, flip a few switches and see which indicators are on.

If the indicator light is normal, it means that the basic circuit is normal.

All eyes are focused on several test circuit boards. Several testers have a freshly baked chip, insert the chip pins into the standard interface, and when everything is ready, they start to flip the switch.

Snapped! bright! Snapped! bright! Just on this kind of non-stop switch on different switches, different indicators light up in turn, and then the testers tick one by one on a form.

Sixteen test chips in the same batch all passed the test in this simple test.

How can it be?

Except for Guo Tailai and the chief teacher who are relatively psychologically prepared, all the people involved in the design and testing are now stunned, looking at the lights that are correctly lit.

Could it be that the operator made a mistake and entered 45 as 85 when entering a number?

The eyes of all the people gathered on the side of a group of testers responsible for operating the microscope.

They rely on microscopes and measuring tools to measure the size of chip circuits.

The test just showed that the basic functions of the chip are normal, and the circuit size cannot be stated, and this most direct measurement will not be false.

"Forty-five nanometers!"

A tester first reported the number with a trembling voice.

Next, there are continuous digital sounds, without exception, all forty-five nanometers, and each sound with a tremor.

When the 90-nm process was successful, everyone was cheering.

But this time, no one made a sound. Everyone Guo Tailai saw in 3D vision, including the master, was all silent, but everyone's eyes were red.
