Siheyuan: I have a mysterious factory

In front of so many people, he couldn't afford to lose this person.

"Let go, let go." Xu Dajun struggled desperately.

It took a lot of effort to remove Qiu Qingzhi.

Xiao Nizi's face was full of anger, and her face was flushed with anger.

"Who is your wife now, big rascal."

Xiao Nizi shouted angrily.

"I..." Xu Dajun wanted to explain.

Before he could finish speaking, Qiu Qingzhi took a second bite.

It's still where it was just now.

"Oh!~~" Xu Dajun quickly held back and screamed in his heart, "It hurts, it hurts, it hurts to death!".

Chapter 180 Seven technological leaps, the first projection lithography machine in China

"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 blushing face.

Even though 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?

Of course the light source.

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 UV light, and the easier it is to engrave.

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

The last piece of the puzzle is to automate the machine.

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 lights are on for a while, it will be very dazzling.

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

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 has done a good job. This is considered a primary success." Xu Dajun said to everyone.

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

Afterwards, everyone continued to be busy.

Next, the parts are assembled one by one.

Originally, they thought 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 actually 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.

The only way to know for sure is if you try it yourself.

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 the projection lithography machine.

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

"This stupid stone, is it intentional, I...I...

Once the equipment is 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 the Chinese New Year.

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

"Everyone, work harder and try to finish 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 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.
