- ¡°Dududu~¡±
Listening to the blind tone coming from the phone, Cao Qirui's mouth twitched slightly.
He can be sure that Su Lang has completely forgotten the truth.
However, Cao Qirui did not blame Su Lang.
If you forget it, just forget it. Wouldn¡¯t it be enough to remind Su Lang?
After a moment¡¯s hesitation, Cao Qirui dialed Chen Guoxing¡¯s phone number.
? Blue Eagle Equipment
Since the lithography machine came off the production line, Chen Guoxing has been stationed here.
As the brightest pearl in the history of human industry, the lithography machine is the crystallization of industrial technology. This does not mean that we can just produce it and ignore it.
It still has a lot to improve.
Such as etching precision, running speed, etc
The lithography machine is really installed on a large scale and requires a lot of testing and improvement!
In the research institute, Chen Guoxing held the experimental report in his hand and frowned slightly.
Just now, a chip etching test was conducted.
The results obtained were not satisfactory.
The defect rate is as high as 2%!
In other words, for every one hundred chips, 2 chips are more or less defective.
Although it seems that this data is not high.
But, you have to know that chips are not counted in hundreds.
It can easily be one hundred thousand or even one million pieces.
A defect rate of 2% means that thousands or tens of thousands of chips are defective, which is absolutely intolerable.
What went wrong?
Chen Guoxing frowned, his expression a little solemn.
Design problem?
Such an idea came to Chen Guoxing's mind.
However, just one second later, Chen Guoxing put it behind him.
Probably not!
If the photolithography machine can be successfully developed, it means that there is no problem with Su Lang's design.
Since it is not a design problem, then it is a process problem.
Maybe it¡¯s because the craftsmanship of certain parts and components failed to meet standards during the manufacturing process, which is why the defect rate remains high.
But which part is it?
Chen Guoxing is still unknown.
¡°Dingling bell~¡±
Just when Chen Guoxing was deep in thought, a clear ringtone from his cell phone interrupted Chen Guoxing's thoughts.
Chen Guoxing's eyelids twitched suddenly, and then his face darkened.
What he hates most is someone interrupting his train of thought when he is thinking.
You know, sometimes inspiration is like that fleeting white dove.
It will slip away if you are not careful!
"snort!"
Chen Guoxing snorted coldly, took out his mobile phone, and answered the call without even bothering to check the caller ID: "Hey, who is it"
The voice was a little cold, giving people a very impatient feeling.
Well¡¡
On the other end of the phone, Cao Qirui was obviously stunned when he heard Chen Guoxing's cold words.
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 he quickly returned to his senses.
"Chen Yuan, who made you angry again?"
Cao Qirui said with a smile.
Who doesn¡¯t have any idea?
Chen Guoxing was about to speak, but he suddenly realized that the voice on the phone sounded familiar.
No matter how you listen to it, it sounds like Cao Qirui¡¯s voice.
Chen Guoxing did not answer in a hurry, but glanced at the caller ID out of the corner of his eye.
Good guy!
It¡¯s really Cao Qirui!
Chen Guoxing's mouth twitched slightly, and his gloomy expression softened slightly.
Although he doesn¡¯t want to admit it, Chen Guoxing has to admit that Cao Qirui still attaches great importance to the lithography machine.
He has also made considerable contributions to the research and development of lithography machines and the deployment of various resources.
"Oh, it's the Cao Department. What's the matter with me, old man?"
Chen Guoxing said with a smile.
"Chen Yuan, Mr. Su called just now!"
Cao Qirui said with a smile.
Su Lang called Cao Qirui?
Chen Guoxing's eyelids twitched and the corners of his mouth couldn't help but twitch.
I don¡¯t know why, Chen Guoxing¡¯sA "sour" feeling came out of me for no reason.
Why did Su Lang call Cao Qirui instead of him?
You must know that he and Su Lang are from the same group, both researchers!
"What did Mr. Su say?"
Chen Guoxing's voice turned cold instantly.
Cao Qirui:? ? ?
Does this old man¡¯s mood change every second?
The sun was shining one second, but the clouds were overcast the next?
"Ahem~"
Cao Qirui covered her mouth with her right hand, coughed awkwardly, and said, "That's it"
Soon, Cao Qirui conveyed Su Lang's intention to Chen Guoxing.
Open the lithography machine?
This can happen!
When Chen Guoxing heard this, his heart suddenly became eager.
Who doesn¡¯t want to straighten up and be a good person?
Others think so, so does Chen Guoxing!
If Su Lang hadn¡¯t stopped him, he would have wanted to reveal the lithography machine a long time ago.
"no problem!"
"I'll make arrangements right now!"
Without the slightest hesitation, Chen Guoxing immediately agreed.
"Okay, Mr. Chen, if you have any requests, just tell me. I will definitely cooperate."
Cao Qirui nodded and immediately expressed his attitude.
"good!"
Chen Guoxing nodded: "Cao Bu, if I have nothing else to do, I will go and prepare!"
He can¡¯t wait to tell everyone the good news.
"Mr. Chen, wait"
However, at this moment, Cao Qirui suddenly stopped Chen Guoxing.
"Mr. 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.
Having said this, the excitement on Chen Guoxing¡¯s face disappeared, replaced by a look of solemnity.
"kindness!"
Chen Guoxing nodded and said: "These problems do exist."
"The defect rate of chips has always been high."
¡°At its highest, it was even more than 2%.¡±
Although Chen Guoxing didn't want to admit it, this was a fact he had to admit.
The defect rate is too high, which will affect subsequent use.
Two percent?
Cao Qirui¡¯s eyelids twitched wildly.
Although his research on lithography machines is not deep, he also knows what the figure two percent represents.

This defect rate is indeed a bit high!
As far as he knows, the defect rate of photolithography machines produced by ASML can be controlled to a few tenths of a percent!
The difference between this time and again is vividly reflected.
"what reason?"
Cao Qirui frowned and said in a deep voice.
¡°The specific issue is not clear at the moment.¡±
"However, Su Lang's design is definitely no problem."
¡°Throw aside design, only craftsmanship remains.¡±
Chen Guoxing said: "According to my guess, there should be a flaw in one or several parts, which affects the overall effect of the photolithography machine."
Compared with some old industrial powers.
China¡¯s industrial base is indeed relatively weak.
Although Su Lang has given specific manufacturing processes and various technologies for various machine tools.
However, this does not mean that parts can be manufactured perfectly.
Sometimes the hardness and flexibility of steel can also determine the effect of a part. (Remember the website address: www.hlnovel.com - Didn't finish reading?
