From all-round academic master to chief scientist - Chapter 233 Triple polishing efficiency!

Lin Xiao’s words were calm, but people felt the power hidden in them.

Can one person change the status quo?

No one knows.

Although this is indeed common sense, what if it is broken?

Nobi Koizumi said nothing more, but took a deep look at Lin Xiao, then waved to other people around him and left here.

Mark Yas, who had been watching the show for a long time, was surprised by Nobi Koizumi’s performance, but he was not surprised. Just like their President Roosevelt evaluated this nation back then, he had nothing to say.

Compared with this, he cared more about what Lin Xiao said.

He glanced at Lin Xiao a few more times. This scientist indeed had amazing talents.

Within a few months, two important breakthroughs were made in CMP materials and servo motor encoders, each of which pointed directly at important areas where they imposed sanctions on China.

What on earth is Lin Xiao going to do?

What is his purpose?

semiconductor?

Or a photolithography machine?

neither knows.

Mark Yas shook his head. Such a powerful scientist really put a lot of pressure on them. No wonder their officials wanted to arrest him.

He didn’t believe their official rhetoric, which was obviously used to deceive ordinary people.

He said nothing more, just nodded to Lin Xiao and left.

The conference room was quiet for a moment, and then curses rang out.

“That little devil is so impudent.”

“What a stupid little devil.”

…

Naturally, the people in the company were all Chinese, so of course they had already become angry.

A group of people cursed.

Luo Ming walked up to Lin Xiao and said, “Professor Lin, don’t be angry with that kind of person. That’s what little devils do. They are respectful in front and arrogant in back. There is no quality at all.”

Lin Xiao shook his head and said, “There is nothing to be angry about.”

This kind of thing is not worth getting angry about.

He was thinking more about the information obtained from this negotiation.

The purpose of agreeing to discuss these two companies this time was to find out their views on this new technology.

Now, they apparently have figured it out.

There is no possibility for foreign countries to make concessions to them for the time being, and it will take a period of hard work.

When they have more key technologies, they will naturally be able to seize the high ground step by step. By then, it will be foreign countries that are anxious.

“Then, let’s first take out the two skills I still have.”

With this thought in his mind, he then asked Luo Ming: “Luo Ming, I’ll let you go to the new company I established, okay?”

Hearing Lin Xiao mention this, Luo Ming said: “It should be done today.”

“Okay, just give me the information later.”

“Okay.” Luo Ming nodded.

Seeing that nothing happened for the time being, Lin Xiao was about to leave when a staff member suddenly scolded him again: “That little devil is so shameless.”

The two of them looked over and saw the employee looking at the newspapers that Nobi Koizumi left behind just now.

The two of them couldn’t help but wonder at this time, why did Nobi Koizumi leave these newspapers behind when he left?

What exactly is up there?

But thinking about it, it’s not such a good thing. Otherwise, why would the staff member scold him?

The two stepped forward, and other employees who heard the sound also gathered around them.

Luo Ming said: “What is above this?”

“These newspapers are all foreign newspapers. They all say that the products made in China are shoddy, and they specifically specify the products of our company.”

After hearing what this employee said, Luo Ming’s expression changed. He picked up one of the newspapers and took a look at it. This was an English newspaper. There was a page next to it that evaluated the world’s industrial countries, including China’s “world factory”. “The title is specifically sarcastic, and later it also mentions their company’s CMP polishing disc. Even though their grinding disc is still building a production line and it will take several months, the newspaper directly asserts that even if it is produced, it will definitely be Inferior product.

After reading it, Luo Ming snorted and said, “This must be a foreign competitor deliberately trying to discredit us.”

Especially companies that compete with their CMP polishing materials.

He picked up a few more newspapers, and indeed they were all similar. Although the wording was different, they basically stated or hinted at their company’s new materials.

This Nobi Koizumi came to negotiate with them, and he even brought this kind of newspaper here. It seemed that he had already intended to disgust them.

Lin Xiao said: “Well, they don’t need to decide whether our products are good or not. What’s more, for the time being, we will not export to foreign countries. We will first meet domestic demand.”

“yes.”

Luo Ming nodded and said no more.

What happened today did not affect the normal operation of Dingguang Technology Company. In the following time, the company continued to operate as usual, and their polishing discs were successfully trial-produced.

These twelve pieces will be taken to their production line specially used for experiments to test the actual performance of this polishing disc.

The previous data on paper are only on paper after all. Only through formal experiments can the final data results prove the excellence of their products, and then give a good counterattack to those foreign remarks that smear their company.

Magic City was originally part of the wafer production line of the silicon industry.

“Be careful, don’t break it.”

Next to the polishing machine, Luo Ming watched the employees replace the internal polishing discs and gave a reminder.

“Don’t worry, Mr. Luo, I’ve been in this business for a long time, I’m sure there won’t be any problems.” The employee said OK with a smile.

Polishing discs are a material that needs to be replaced very frequently. The previous replacement frequency was about once every three days, so these employees are familiar with the replacement process.

Of course, because of this, more wear-resistant grinding disc materials are more popular in the market.

According to the paper data of their new grinding disc material, it should have better wear resistance than the grinding disc material they used before.

So they are all looking forward to the performance of this new material.

Soon, the grinding disc material installation was completed.

Next, the silicon wafer that has only been polished for the first time is put up and polished.

Soon, several silicon wafers with relatively rough surfaces were carried over by employees and put into the assembly line. The mechanical operation in the assembly line automatically placed these silicon wafers into the polishing machine.

Then, the polishing machine started running.

The large grinding disc rotates squeakingly, and the silicon wafer revolves around the circle of the large grinding disc while still rotating. This form of polishing is called planetary polishing.

This method allows the silicon wafer to be polished more thoroughly.

And watching the operation of the polishing machine, everyone around them began to look forward to it.

After a long period of polishing, the polishing machine finally stopped running and then pulled out the silicon wafers that were being polished inside.

The employees immediately took out these silicon wafers, and then put new rough silicon wafers into the assembly line, and the polishing machine operated again to continue polishing.

Of course, now they no longer care about the polishing process, but about the silicon wafers that have been polished.

What they care about is the polishing result and whether it can reach a first-class level.

Soon, they took this thing to the measuring instrument next to it.

After the silicon wafer is polished, it needs to be placed on a measuring instrument for factory inspection to avoid defective products.

In the past, their defective rate was higher than that of foreign companies. I wonder how their defective rate will be after using new grinding disc materials.

The detection method is to use the laser interferometer to detect the surface accuracy, which can be used for 1-10nm. Of course, the lower the better, the better the sales. For example, if the surface accuracy is 10nm, unless there is a real shortage of silicon wafers in the market, it is basically No manufacturer will buy it.

Not long after, the test results came out.

The staff shouted in surprise: “It shows the accuracy, all are around 4nm! There are no defective products!”

Upon hearing this result, everyone present cheered.

Luo Ming’s eyes also lit up.

4nm precision, if their polishing fluid is better, wouldn’t it be possible to achieve 2 or 3nm?

Of course, 4nm precision is enough to open up sales.

“Okay! Continue testing!” Luo Ming said with a smile.

Now there are only a few pieces, and more need to be tested to determine the final yield rate.

Just like that, three days passed.

Luo Ming also stayed here for three days.

“The accuracy of this batch is 6nm!”

The inspector’s voice shouted again, and once again people cheered.

Their grinding disc was ground for three days, and the accuracy was still maintained at 6nm. This undoubtedly shows that their grinding disc has high wear resistance. Compared with their previous material, it is simply better.

“What about the yield rate?”

“The yield rate is 99%.”

“Yes.” Luo Ming nodded and began to think in his mind.

The yield rate did not reach 100% because several silicon wafers had cracks during the polishing process due to defects caused during the purification process, so they were classified as defective products.

So these are not polishing issues and do not need to be considered.

If you think about it this way, their polishing speed can be accelerated.

The faster the polishing speed, the higher the output will naturally be.

Thinking of this, Luo Ming immediately said: “Increase our polishing speed to 1.5 times the current rate.”

“good!”

When the employees heard what Luo Ming said, they immediately responded.

Luo Ming then said: “After replacing the new millstone, we will continue to maintain it at 1.5 times, and then it seems that it can be doubled.”

“Use our new millstone to its full potential!”

“good!”

The employees responded excitedly again.

The faster they sand, the higher their output!

The life of a polishing disc is not as long as possible, but should be described in terms of durability. Some polishing discs can only be used for two days, but this kind of polishing disc is not necessarily as good as those that can be used for three days.

If this kind of polishing disc that can only be used for two days has a polishing speed twice that of a three-day polishing disc, then it will be decided which one is better.

But now, their new material is completely capable of reaching the level of this top-notch material!

Luo Ming was extremely surprised.

At this time, a voice suddenly came from behind: “Mr. Luo.”

Luo Ming turned around and saw Yu Jiancheng coming over.

“Mr. Yu, are you here?”

Yu Jiancheng heard that Luo Ming was testing new materials in the past two days, so he wanted to come over and take a look at the situation.

Seeing the happy looks on the faces of the people around him, he couldn’t help but have a guess in his mind, rubbed his hands, and asked uncontrollably: “Mr. Luo, how do you think of this new polishing disc material? “

Luo Ming stretched out his hand with a smile and showed a finger.

Yu Jiancheng was stunned: “Mr. Luo, what does this mean?”

Luo Ming smiled and said: “World-class!”

Yu Jiancheng was stunned again, and then a surprise expression appeared on his face: “What do you mean?”

“Don’t worry.” Luo Ming patted his shoulder and said with a smile: “Leave this production line to us, and you will make a lot of it later.”

Hearing what Luo Ming said, Yu Jiancheng only had two words in his mind, it’s done!

It seems that their new material is somewhat beyond expectations.

He laughed: “Okay, with these words from Mr. Luo, I feel much more at ease.”

“Well, don’t worry. While there are still a few months left, you’d better be ready to speed up the steps before polishing. Otherwise, you’ll be polishing faster, but you won’t be able to keep up, and you’ll be heartbroken by then. But yourself.”

“Okay, okay.” Yu Jiancheng nodded, very happy.

These are just small things.

At this time, he recalled that he actually regretted this incident, and couldn’t help but patted his face.

Fortunately, fortunately.

…

A few days later, the final test results came out.

Compared with the polishing discs they used before from Japan, their new material is stronger in all aspects.

Based on comprehensive judgment, in the polishing step, their overall polishing efficiency increased to three times!

three times!

If you use a better polishing fluid, it is not impossible to get four or five times the polish.

Luo Ming immediately shared such good news with Lin Xiao.

…

At this time, Lin Xiao, who was at Beijing University and was about to give a number theory class to sophomore students, heard the news from Luo Ming and smiled on his face.

very good.

I don’t know what expressions the competitors will show after learning the news.

Of course, Lin Xiao was not looking forward to this.

Just do his own thing.

In the past three days, I have been subject to review and sanctions, and they were all sent a little late.

People are numb
