Siheyuan: I Have A Mysterious Factory

"Your father is not here, no one can cure you, right?" Xu Dajun rubbed his bitten arm and said with extreme contempt.

"Whoever told you to take advantage of others, I can sue you for being a hooligan and arrest you." Qiu Qingzhi said with a red face.

Although her face was blushing, Xiao Nizi still didn't give in at all.

"I don't care like you." Xu Dajun ignored her.

Qiu Qingzhi also turned her head away and devoted herself to the research.

What is the most important thing about a lithography machine?

Light source of course.

Today's lithography machines generally use ultraviolet light.

Ultraviolet light can be obtained using high-pressure mercury lamps.

Subsequently, other light is filtered out, which is the ultraviolet light used by the lithography machine.

Second most important.

To control the wavelength of ultraviolet light.

The shorter the wavelength, the sharper the ultraviolet light, and the easier it is to engrave.

Other problems that need to be dealt with are the need to average the energy so that the desired chip can be carved smoothly.

The last problem is to make the machine run automatically.

After all, during "lithography", the semiconductor silicon wafer needs to move at a constant speed.

This is not something that manpower can do, only numerical control technology can be used.

These are all problems that need to be solved.

It can be said that these are also the top problems in the world today.

Xu Dajun didn't have any worries.

He first built a high-pressure mercury lamp according to the memory in his head.

Then, it is how to make the high-pressure mercury lamp output stable ultraviolet rays.

Meanwhile, others are doing research.

Gao Yuanhang and his team are researching

Even if there are blueprints, it is not a simple matter to manufacture this lithography machine.

After half a month of busy work, everyone has prepared most of the parts.

Xu Dajun led the crowd to assemble these parts.

The first thing to assemble is the high-pressure mercury lamp.

It can make the high-pressure mercury lamp emit enough light.

Even, the intensity of the light must be at the highest level, and it should be very stable.

This is not a simple matter.

Fortunately, with the efforts of Xu Dajun, everyone successfully assembled.

"Try it with power on". ” Xu Dajun gave the order.

After saying this, he walked up to Qiu Qingzhi's side and covered her eyes with his hand.

Because, when the light is on for a while, it will be very dazzling.

If you accidentally look directly at it, your eyes will be very uncomfortable.

Qiu Qingzhi looked at him, feeling a little moved in her heart.

If Xu Dajun is serious, he must be a good man.

Immediately afterwards, after the high-pressure mercury lamp was energized, it lit up.

Seeing the strong light, everyone present knew that they had succeeded.

Several people couldn't help cheering.

Xu Dajun also smiled.

"Everyone is doing very well, this is considered a primary success." Xu Dajun said to the crowd.

This matter can be regarded as giving them sufficient self-confidence.

Afterwards, everyone continued to be busy.

Next, each chronicle was assembled by everyone.

Originally, they thought that there was no hope of making this lithography machine.

As a result, I watched these parts being made and assembled one after another.

The expectations in the hearts of the people are also stronger.

At this time, what else can I say.

They watched as the lithography machine was about to be made.

Everyone's heart is full of excitement.

An impossible thing.

It was under the command of Xu Dajun.

Gradually towards success.

Everyone gritted their teeth.

Desperate to complete this unit.

Xu Dajun looked at the crowd with a smile on his face.

More often than not, that's the way it is.

Things that seemed impossible in the first place.

Only by trying it yourself can you be sure whether it will work or not.

Qiu Qingzhi's complexion became more and more broken.

Xiao Nizi felt conflicted.

Obviously, in her opinion, this task is impossible to complete.

Relying on domestic technology, it is impossible to break through and reach the projection lithography machine.

As a result, now the machinery and equipment are about to appear in front of my eyes.

"This stupid stone, did you do it on purpose? I.....I...."

When I think of the equipment being built, I will be Xu Dajun's wife.

She was extremely shy, but she had some expectations in her heart.

"Shame to death, this stupid army! What should I do."

Qiu Qingzhi felt very embarrassed.

At this time, Xu Dajun still showed a provocative expression to her.

"Bad guy!"

Qiu Qingzhi said viciously in her heart.

Finally, after two months, all the parts were ready.

Xu Dajun checked the time, and it was less than a week before Chinese New Year.

It seems that I need to complete everything within a week.

"Let's work harder and try to complete it before the end of the year." Xu Dajun said.

"I'm so tired. We will never let Xu Guoshi down." Everyone was also full of energy.

After what happened before.

They also know that it is only a matter of time before this lithography machine is manufactured.

As long as there is Xu Dajun's command, it is also possible to complete it before the end of the year.

Xu Dajun looked at the crowd with a smile on his face.

Then, he turned to Qiu Qingzhi.

Qiu Qingzhi was in charge of the mechanical programming.

At this time, I don't know if I should slow down my programming.

If this equipment cannot be completed before the end of the year, I don't have to go to his house with Xu Dajun.

But... look at the people around you.

Qiu Qingzhi couldn't do such a thing that would harm everyone's interests.

Gritting her teeth, she still finished the CNC program.

Xu Dajun glanced at Xiao Nizi and smiled with satisfaction.

". "Comrade Xiaoqiu, you are very enlightened!" Xu Dajun said.

"Call my sister!"

Qiu Qingzhi gritted her teeth viciously, and shook her fist at Xu Dajun, looking extremely ashamed.

Xu Dajun looked at her and smiled happily.

It can be seen that Qing Tian chose to accept her fate.

After all, my father said it before.

If you don't bring your daughter-in-law home, you won't be allowed to enter the house during the Chinese New Year.

After much deliberation, Xu Dajun could only focus on Qiu Qingzhi.

Who made him have so few female friends.

Besides, the relationship between the two of them is so good, and it is only right for them to help their friends solve problems.

Finally, after everything is ready.

Xu Dajun led everyone to start the final assembly.

It took two full days (for Wang Zhao).

The projection lithography machine is manufactured.

However, everyone held back the excitement in their hearts and watched all this.

For them, the lithography machine can operate normally, and they are done.

"Power on!"

Xu Dajun ordered.

Someone switched on the power.

Immediately afterwards, the lithography machine started to operate.

After the ultraviolet rays are processed layer by layer, they are projected onto the semiconductor silicon wafer.

A pattern that has been set long ago is engraved on the silicon wafer.

The next moment, everyone cheered.

"We made it!!!"

"Long live the motherland, long live the people!"

"We produced the first projection lithography machine!"

They fell into mad joy.

Seeing this, Xu Dajun breathed a sigh of relief, and a smile appeared on his face.

At this time, he felt a soft little hand grabbing his yellow-covered minister.

Suddenly, a warm current flowed into his heart.
