Live broadcast of my blind date with Miss Dai, sister Zhou was arrested

Looking at Ye Tian, ​​Professor Yu asked with a smile.

"It's a little weird."

Ye Tian nodded honestly.

He really didn't understand.

Professor Yu sighed: "You are still young, and you don't understand how serious foreign technical barriers are to us. Those old professors have all experienced that kind of pain. As they say, having a father and a mother is not as good as yourself Yes. I have been counting on others to give me food, it’s uncomfortable!"

hiss!

Ye Tian took a deep breath in his heart.

He finally understood,

Why did those old men hesitate to spend so much money to re-manufacture new machines?

But after hearing those few words of his own, they all got excited.

It's been a long day,

He was bullied so badly by others!

think about it.

Thinking about how close our relationship with Big Brother was back then, it would eventually break down.

Not to mention those foreigners now.

If only one day.

They imposed a blockade on our lithography machines.

We can't even buy a lithography machine, what kind of situation will it be?

It's really like what I said, it's better to have a father than a mother.

As long as you can independently develop and produce lithography machines, you don't have to worry about being blocked by other people's technology.

and.

If only our technology were a little better...

Hey,

That scene is simply unbearable!

"I understand."

Ye Tian nodded.

"Okay, let's go then."

Professor Yu said to Ye Tiandao.

In the next half month.

All kinds of machine accessories are requested and sent to all parts of the country.

After receiving the task, those factories also worked overtime to make the parts.

No one knows what the parts they make are useful for.

The only certainty is that

The requirements for parts are extremely high, and even a zero-to-one error is not allowed.

After half a month.

Inside a laboratory of the Shencheng Institute of Science and Innovation.

There are all kinds of machines, large and small, here!

The laboratory, which originally occupied a large area, is now completely filled with machines!

And the shapes of all kinds of machines look strange, and I don't know what they are made of.

In the middle, there is a huge machine.

The machine is surrounded by a completely transparent plastic plate to wrap.

"Success?"

Looking at the newly assembled machine, Professor Yu's voice trembled, and he looked at Ye Tian.

Ye Tian took a deep breath, and ordered the technician next to him: "Make a wafer and apply glue."

"Ok."

The technician agreed.

"Prepare a computer with EDA software."

Ye Tian gave instructions to the people around him.

The so-called eda software is the necessary software for designing electronic chips and circuit boards.

Covers all aspects of ic design, circuit board design routing, verification and simulation, and testing.

"no problem."

Soon someone brought the computer over.

"Put the wafer in place, follow the procedure, and let's get started!"

With Ye Tian's words.

All eyes focused on the lithography machine.

Will Ye Tian's plan succeed?

PS: Ask for flowers, ask for evaluation tickets, ask for rewards! .

Chapter 25 The first lithography machine (4, asking for flower evaluation tickets)

Under Ye Tian's order.

A staff member put the wafer into the lithography machine.

Next,

That's the most critical part.

Start the lithography machine!

"By the way, Xiaoye, what is that machine?"

At this moment.

Someone pointed to another machine and said.

"That's an etcher."

Ye Tian was very calm.

The etching machine is relatively simple, and it is matched with the materials of the lithography machine.

Ye Tian didn't think much about it at the time, and drew the design of the machine parts casually.

"Come on, let's look at the lithography machine first."

Professor Yu greeted everyone and focused his attention on the lithography machine.

Start the lithography machine, and irradiate it through the mask with the printed circuit through the ultraviolet light of the lithography machine.

The exposed part will be dissolved and cleared, thus forming a corresponding circuit structure on the surface of the crystal!

Seeing this scene, Ye Tian felt a little excited in his heart.

Although in my mind, I already have knowledge about the manufacture of lithography machines.

But it is still very exciting to actually manufacture this lithography machine.

"Underneath is etching."

Seeing the completion of the lithography machine, Ye Tian immediately ordered people to start the next test.

This step is actually not complicated.

Firstly, the exposed silicon wafer is etched away by an etching machine.

And the photoresist on the silicon wafer is removed, and then the grooves are exposed.

Ions are then implanted to give the silicon the properties of a transistor switch.

Copper is then used to connect the transistors.

After stacking layers, an intricate chip structure is formed.

Seeing these steps being carried out in an orderly manner, all the experts in the laboratory held their breath and stared at the etching machine without blinking their eyes.

"Is this a success?"

A younger engineer asked cautiously.

"To shut up!"

He was greeted by a group of old men with serious expressions.

The guy almost fainted from fright.

To know.

Among the few old men just now, there are many big men with academician level.

Even the director of the Institute of Science and Innovation has to bow and greet people when they see them.

But now.

But they were like curious babies, staring at the etching machine wholeheartedly.

Time passed by minute by minute.

at last.

I don't know how long has passed.

A silicon wafer with chips already manufactured appeared in front of everyone.

On this wafer, chips are manufactured piece by piece.

The next process is cutting, binding and so on.

"Successful, successful?"

Rao was always calm and composed, but his voice trembled a little at this moment.

Looking at the chips on the large spar that have not been cut into pieces.

Everyone was dumbfounded.

They stared blankly, their mouths opened wide as if they wanted to eat their own fists.

"It should be successful."

Ye Tian smiled and said: "After cutting and packaging, you can try it out. If there is no problem, our project will be officially successful, right?"

This sentence.

He looked at Professor Yu and the group of old men behind him and asked.

"That's right!"

"Yes, yes, try first, try first."

"Don't worry, hold on, all of you hold on."

"I'll do it, I'll do the cutting."

"Use it for you? Look at mine."

"Let me do it."

"Go away, I'm three years older than you."

"Are you shameless, I am Ye Tian's teacher!"
