Technological power starts with upgrading lenses

[Major breakthroughs have been made in domestic monocrystalline silicon purification technology—after the Ministry of Science and Technology released special support funds for silicon wafers, the first support fund has been approved! 】

Just the day Kang Chi finished his interview, a piece of industry news caught his attention.

Good guy,

He is already working hard to speed up the progress,

He didn't expect these people to be faster than him.

Although Kang Chi had already been mentally prepared for this, when Kang Chi had already regarded this piece of cake as his own, he would inevitably feel a little painful if anyone tried to cut a piece from it first.

Um,

On human greed...

Kang Chi is just a layman. Although he has lofty ambitions to benefit the masses, he also has his own "small belly chicken intestines" when faced with the temptation of such huge benefits.

He took a closer look at the content of the news. It reported that Silicon Information Technology used a self-developed single crystal furnace and successfully pulled out a 12-inch single crystal silicon rod using the Tchaikolaski pulling method - although this Only the first 5cm of a 1.5-meter silicon rod meets the 11 9-purity semiconductor grade requirements.

But this is indeed a breakthrough.

The Ministry of Science and Technology finally issued a special scientific research subsidy of 30 million to Silicon Information Technology.

"It's okay, it's okay, it's only 30 million, just 1% of 3 billion!"

Kang Chi could only comfort himself in this way, lest he couldn't sleep tonight...

On the night when this text news was released, the Technology Channel also broadcast a video version of this news.

The host conducted an exclusive video interview with Dr. Yan Hui, the chief technical consultant of Silicon Information Technology.

In this exclusive interview, the reporter used Dr. Yan’s words to introduce the production process and technical difficulties of monocrystalline silicon rods to the audience.

At the same time, the principle and process of the Tchaikolaski Pulling Method were explained.

"The principle of the Czochralski method is actually very simple. It is a bit similar to the principle of pouring water into ice in the north. Just heat the polycrystalline silicon to 1,700 degrees in a quartz crucible, smelt it into a liquid state, and then melt the prepared single crystal A thin silicon rod is inserted as a seed crystal and slowly pulled upward to pull out a large-sized single crystal silicon rod."

"Although the principle is very simple, that is, the small stick goes in and the big stick comes out, there are many technical difficulties in the actual operation, so I won't go into details here..."

On the TV, Dr. Yan vividly demonstrated the principle of the Ti-La method with some small props around him. Even ordinary people can understand the general idea after watching it once.

Near the end of the interview, the host suddenly changed the topic and asked Dr. Yan another question:

"I heard that in addition to the Czochralski method, there are also suspension methods and floating belt methods that can also produce single crystal silicon. Especially the floating belt method that has attracted widespread attention in the industry due to three papers published in "Electronics and Computers" some time ago. , Dr. Yan, what do you think of them?"

Yan Hui was stunned for a moment, obviously not expecting the host to ask this question.

He collected his thoughts for a moment before answering: "I have also read those papers, and there is indeed no big problem in theory. However, in fact, the floating belt method has always been controversial in the industry, and silicon wafers are not easy to write. It can be written in just one paper.”

"Even Shin-Etsu Chemical, which currently conducts the most in-depth research on the floating belt method, has publicly admitted that this technology is not yet mature and is still a long way from practical application."

The host nodded and continued to ask: "So do you think it is unrealistic for Dahan Silicon to manufacture single crystal silicon rods by improving the floating belt method?"

"Well...at least in the short term, I think the hope of success is a bit slim, especially since their investment in scientific research funds and talent reserve seem to be far from enough."

Facing the reluctant host, Dr. Yan also spoke out and expressed his truest opinions.

"Of course, according to probability, nothing in the world is guaranteed. Personally, I still hope that they can achieve cornering overtaking in the floating belt method and break this technical barrier for domestic silicon wafers. "

"Okay, thank you Dr. Yan for bringing me wonderful science..."

After this news was broadcast, it quickly attracted a lot of attention in the semiconductor field.

Previously, everyone speculated that there would be a major breakthrough in domestic silicon wafers, and the breakthrough point would be in the manufacturing of silicon rods.

But after Dr. Yan’s analysis, everyone couldn’t help but become suspicious, thinking that Dr. Yan’s analysis was not unreasonable.

After all, in the field of domestic silicon wafer manufacturing, the person with the most say is not Academician Wu, but Silicon Information Technology.

Of course, it does not rule out the possibility of peer competition and deliberate belittling of opponents.

In short, after the Ministry of Science and Technology issued a document announcing this year’s semiconductor-related policies, the entire domestic semiconductor industry is filled with a strong smell of gunpowder.

Among them, the silicon wafer manufacturing field has received the most support.

After all, this field has been on the bench for too long...

Now that you have finally been cared about by your superiors, why don't you behave well?

In the following period, in addition to XinSi Technology, more than a dozen companies and scientific research teams successively announced their latest results, involving many aspects including silicon rod purification, chamfering, slicing, polishing, etc.

In the end, eight companies passed the review of the Ministry of Science and Technology and received a total of 140 million support funds.

As a result, more than 200 million of the 3 billion in special scientific research support were divided up.

But Kang Chi didn’t panic.

Because he knows very well that these are the results they have accumulated in the past. After this period of time is over, it will not be so easy for them to come up with breakthrough results to share the cake.

When the Ministry of Science and Technology set up the support fund of 3 billion, it certainly did not plan to distribute it all at once...

This was originally a tug-of-war that took months or even years.

January 18, the sixth day of the twelfth lunar month, Steel City High-tech Industrial Development Zone.

With the sound of gun salutes, the foundation laying ceremony of the first phase of Dahan Silicon Industry began.

On the land that has been leveled, a red background board prepared in advance stands behind the cornerstone.

In the front were hundreds of invited guests from all walks of life and all employees of Dahan Silicon Industry.

As the chairman of Dahan Silicon and today's protagonist, Kang Chi was also dressed up very brightly today, with shiny leather shoes, a crisp suit, and neat hair, which was completely different from his previous casual temperament.

Kang Chi originally refused, but Zhang Qing repeatedly stressed to him the importance of today's occasion.

When he arrived at the scene, he was immediately glad that he had listened to Zhang Qing's words, otherwise he would have stood like a local leopard among so many important leaders...

It's really out of character.

"Mr. Kang, congratulations!"

"Thank you, Deputy Mayor Huang. If it weren't for your full support during this period, our progress would not be so fast!"

"Haha, it should be, it should be, these are our Secretary Yuan and Mayor Lu..."

"Ah, hello Secretary Yuan, hello Mayor Lu, thank you for being so generous..."

"No, no, this is a great event for Steel City. As hosts, how can we not come ourselves?"

"Congratulations, Mr. Kang. I wish your company will continue to innovate and reach new heights in the future..."

“And there’s money rolling in!”

"Haha, thank you leaders for your blessings..."
