Shenhao: Kill ten shops instantly with eight yuan at the beginning

Chapter 1448

"Dududu~"

Listening to the busy sound from the mobile phone, the corners of Cao Qirui's mouth twitched slightly.

He was sure that Su Lang had forgotten about it.

However, Cao Qirui did not blame Su Lang.

Forget it, forget it, remind Su Lang that it is not enough?

After a little hesitation, Cao Qirui dialed Chen Guoxing's phone.

Blue Eagle Gear....

Since the lithography machine came off the production line, Chen Guoxing has been stationed here.

As the most brilliant pearl in the history of human industry, the lithography machine is the crystallization of industrial science and technology, which does not mean that it can be ignored if it is produced.

It still has a lot to improve.

Such as etching accuracy, such as running speed, etc....

The lithography machine is really a large-scale installation, and it needs to go through a lot of testing and improvement!

Just now, a chip etching test was conducted.

The results were not as good as they could have been.

In other words, for every 100 chips, 2 chips are more or less defective.

Although it seems that this number is not high.

However, you have to know that chips don't count in hundreds.

It's 100,000, or even millions.

The defect rate of 2 percent means that there are thousands, tens of thousands of chips with defects, which is absolutely intolerable.

What went wrong?

Chen Guoxing's brows were furrowed, and his expression was a little solemn.

Design problem?

Chen Guoxing had such an idea in his mind.

However, just a second later, Chen Guoxing left it behind.

The

lithography machine can be successfully developed, which means that there is no problem with Su Lang's design.

Since it's not a design problem, it's a process problem.

Perhaps it is because some parts are manufactured that the process level is not up to standard, so the defect rate remains high.

But which part is it?

Chen Guoxing is still unknown.

"Jingle bell~"

Just when Chen Guoxing fell into deep thought, a crisp mobile phone ringtone interrupted Chen Guoxing's thoughts.

Chen Guoxing's eyelids jumped suddenly, and then his face became gloomy.

What he hates the most is that someone interrupts his train of thought while he is thinking.

You know, sometimes inspiration is like a white dove that flashes away.

If you're not careful, it will slip away!

"Hmph!"

Chen Guoxing snorted coldly, took out his mobile phone, and didn't care about the caller ID, so he directly connected the phone: "Hey, who..."

Uh....

On the other end of the phone, hearing Chen Guoxing's cold words, Cao Qirui was obviously stunned.

He didn't understand why Chen Guoxing was so "unhappy".

But fortunately, Cao Qirui can be regarded as a person who has experienced strong winds and waves, and soon returned to his senses.

"Chen Yuan, who made you angry again?" Cao

Qirui said with a smile.

Chen

Guoxing just wanted to speak, but he suddenly realized that the voice on the phone was a little familiar.

No matter how you listen to it, it looks like Cao Qirui's voice.

Chen Guoxing didn't answer in a hurry, but glanced at the caller ID out of the corner of his eye.

The

corners of Chen Guoxing's mouth twitched slightly, and his gloomy expression eased slightly.

Although he doesn't want to admit it, Chen Guoxing has to admit that Cao Qirui still attaches great importance to lithography machines.

He has also made great contributions to the research and development of lithography machines, the allocation of various resources.

"Oh, it's Cao Bu, is there anything wrong with looking for me, old man?"

Chen Guoxing said with a smile.

"Chen Yuan, Su Xiaozi called just now!" Cao

Qirui said with a smile.

Su Lang called Cao Qirui?

Chen Guoxing's eyelids jumped, and the corners of his mouth couldn't help twitching.

I don't know why, Chen Guoxing's chest gushed out a "sour" feeling for no reason.

Why did Su Lang call Cao Qirui instead of him?

You must know that he and Su Lang are all the way, and they are both researchers!"

"What did Su Xiaozi say?"

Chen Guoxing's voice instantly became cold.

Cao Qirui: ??? this old man's mood changed in a

second? The sun was shining one second, and the next second it was "cloudy"?

"Ahem~

" Cao Qirui

covered his mouth with his right hand, coughed embarrassedly, and said, "That's the case..."

When

Chen Guoxing heard this, his heart suddenly became eager.

Who doesn't want to straighten his waist and be a man?

Others think, and Chen Guoxing also thinks!

If it weren't for Su Lang to stop him, he would have wanted to make the lithography machine public a long time ago.

"No problem

!" "I'll arrange it!" Without

the slightest hesitation, Chen Guoxing immediately agreed.

"That's okay, Old Chen, if you have any requirements, just say it, and I will definitely cooperate here.

Cao Qirui nodded, and immediately showed his attitude.

"Okay!"

Chen Guoxing nodded: "Cao Bu, if I have nothing else, I'll go and prepare!" He

couldn't wait to tell everyone the good news now.

"Chen Lao, wait..."

However, at this time, Cao Qirui suddenly stopped Chen Guoxing.

"Old Chen, there is one more thing. "

I heard that there seems to be a problem with the testing of the lithography machine?" Cao

Qirui asked in a deep voice.

Speaking of this, the excitement on Chen Guoxing's face disappeared, and was replaced by a touch of solemnity.

"En!"

Chen Guoxing nodded and said, "There are indeed some problems.

"The defect rate of chips has always been high.

"At its peak, it was even more than two percent.

Although Chen Guoxing didn't want to admit it, this was a fact that he had to admit.

The defect rate is too high, which will affect subsequent use.

Two percent?

Cao Qirui's eyelids jumped wildly.

Although he didn't have a deep understanding of lithography machines, he also knew what the number of two percent meant.

As

far as he knows, the defect rate of the lithography machines produced by ASML can be controlled at a rate of more than 0.00 percent!

This back-and-forth gap is vividly and vividly reflected.

"What is the reason?" Cao

Qirui frowned and said in a deep voice.

"The specific question is not clear for the time being.

"However, Su Lang's design is definitely fine.

"Aside from the design, it's just the craftsmanship.

Chen Guoxing said: "According to my guess, it should be a certain one, or several parts have defects, which affect the overall effect of the lithography machine." "

Compared to some of the old industrial powers.

It is true that China's industrial base is relatively weak.

Although Su Lang has given the specific manufacturing process, as well as the various technologies of various machine tools.

However, this does not mean that the parts will be perfectly manufactured.

Sometimes the hardness and flexibility of steel can also determine the effect of a part.
