Are You Crazy, Do You Call This a Copycat Machine?

From sand to chips.

The entire chip production process is a huge industry chain.

There are a lot of complicated loops in it.

And lithography is one of them, and it is a very technically difficult one.

It is also the top priority that has always restricted the development of the domestic chip industry.

without any exaggeration.

The lithography machine is the crystallization of the world's industrial system for hundreds of years. The entire machine requires more than 30,000 parts, and each part cannot have the slightest deviation. The slightest deviation can not make tens of millions of circuits intact and unbiased. On top of a fingernail-sized chip.

Make a chip.

The first thing to do.

Is to make a wafer sheet.

If you use printing to describe the entire work.

Then the wafer is the blank paper in which the pen and ink are carried.

Lithography is to print a complete circuit on this piece of paper with a lithography machine.

Among them, wafer processing and oxidation are designed to obtain a complete wafer with a clean surface and an oxide protective film.

The processing of the wafer is very precise.

The requirements have reached the nanometer level, which is only the simplest step in the chip manufacturing process.

Following Chen Fei's order, it was issued.

Suddenly, the production line that had already been installed and debugged in place was started.

For the equipment produced by the system, Chen Fei naturally has no worries.

But except for him.

At this moment everyone else is watching the first two steps of the production line nervously.

Although the wafer can be used as a finished product.

But according to Chen Fei's chip manufacturing process integrity requirements.

Even the wafers are made by Xinhe itself.

After some technological process.

Pieces of complete wafers appeared in front of everyone.

Through the production line, professional machines audited it.

The set parameter thickness of a wafer is about 0.670mm, and the error should not be greater than 0.0001mm, which is 100 nanometers.

The detection data of the instrument will also be accurate to 0.00001 mm, which is between 10 nanometers.

this will.

Mo Xiangnan's eyes widened, looking at the dashboard in front of him.

Success or failure in one fell swoop!

soon.

Five sets of test data are released!

0.67000mm! 0.67000mm! 0.67000mm! 0.67000mm! 0.67000mm!

Seeing this data, Mo Xiangnan was a little stunned.

He was shocked.

He even wondered if there was a problem with the instrument.

In the nano-level accuracy test, the deviations are all 0!

This shows that the error of these wafers has been completely smaller than the detectable range of the test!

Allow 100nm error, and as a result, there is not even 10nm!

Looking at the equipment in front of him, Mo Xiangnan's eyes were about to come out!

Such high-precision wafer production equipment, even the top foreign chip manufacturers can't make it!

call..

call..

Mo Xiangnan took a few deep breaths.

Now is not the time for excitement, the most important steps are still to come.

Whether a chip can be made successfully, the key depends on the lithography machine

The lithography machine is the top priority!

Lithography.

It can be understood that the circuit pattern is "printed" on the wafer by light.

Among them, the higher the fineness of the circuit pattern, the higher the integration degree of the finished chip.

A lithography machine can be said to be a finished technology equipment that integrates all the top technologies of mankind.

That's right, it's the entire human race!

Why can't we produce high-precision lithography machines in China? That's because many technologies have been stuck.

High-precision components such as light source, energy controller, mask, lens, etc.

Even if it is the same, the technical difficulty will break through the sky.

Not to mention, the entire lithography machine has tens of thousands of parts.

The precision requirements for chip production must reach the nanometer level.

What is the concept of a nanometer? It's almost as small as one-five thousandths of a strand of hair.

So now, Mo Xiangnan can't believe it.

Chen Fei can come up with a lithography machine that can burn 14nm chips.

Of course, it is impossible for him to disassemble this lithography machine for research, and it is naturally difficult to understand the true accuracy of this lithography machine.

Everything.

It is only at this moment of practice to know!

Slowly, the wafer entered the lithography machine.

--Although the lithography machine is a very complex equipment with a lot of precision parts, its working efficiency is not low at all. It can complete the lithography of 8 chips in about 0.15 seconds.

The wafer enters the lithography machine. From the outside, people can also see a light beam on the surface of the wafer for laser engraving.

After all, it is impossible for the human body's naked eye to reach the nanometer level.

Zi Zi Zi Zi

……For flowers………

The surrounding instruments make noises from time to time.

But the technicians like Mo Xiangnan would not hear anything.

Their eyes are all focused on the lithography machine.

What I can hear is the thumping heartbeat in my ears.

no way

Too nervous

There was only Chen Fei, standing on the side with confidence, without seeing any tension on his face.

Yes, it's just full of excitement.

He doesn't think the equipment will fail.

All they need to do is to wait for the chips to be successfully produced.

The process is of course complicated, but these processes have been concentrated on the lithography machine.

so.

Not for a while.

The finished wafer, or the wafer that has been mounted on the circuit pattern, comes out of the lithography machine.

It succeeded!

...0

Mo Xiangnan clenched his fists excitedly!

Looking at the neat little squares in the wafer, he was a little bit too excited about it.

But he still didn't shout out.

For fear of disturbing these instruments and equipment.

Although there is a protective layer, he is also afraid that his tiny sound waves will affect the inside.

And next.

Etching, thin film deposition, so that one by one nanometer-level transistors, electronic components are formed on the surface of the wafer.

After the last interconnection process, all the components form a path to reach an interconnected state.

then.

The complete chip core is successfully presented to everyone!

Next, it's the same as all products.

The chip also needs to be tested.

And this step is also the step that Mo Xiangnan cares most about.

Because only through this step, they really know the real power and performance of these chips!

For the same chip, the performance and power consumption will be worse due to the difference in nanotechnology.

And nanotechnology refers to the distance between the transistor and the circuit between the transistor.

So, relatively speaking, 14nm will have many more transistors than 28nm chips, and the performance and power consumption will be much stronger.

And among them.

If it is the same nano-technology chip, the test is the accuracy of the machine.

The higher the accuracy, the less the distance between the circuits and the fewer circuit defects, which can naturally improve performance and power consumption.

This.

It is also something that Mo Xiangnan and the others cannot see with their naked eyes!

After the precision test of the instrument.

The data is out!

And at the same time.

Mo Xiangnan finally couldn't help but exclaimed, "How is this possible!"
