Chapter 54 Groundbreaking Ceremony
[Major breakthrough in domestic monocrystalline silicon purification technology – after the Ministry of Science and Technology issued special support funds for silicon wafers, the first support funds have been allocated! ]
Just on the day when Kang Chi finished the interview, a piece of industry news caught his attention.
Good guy, he has been trying to speed up the progress, unexpectedly these people are faster than him.
Although he was mentally prepared for this, when Kang Chi had already regarded this piece of cake as his own, anyone who took a piece from it first would inevitably feel a little painful.
Well, On the greed of human nature…
Kang Chi is just a layman. Although he has a lofty ambition to benefit the masses, he also has his own “small stomach” in the face of such huge temptations of interests.
He carefully read the content of the news, which reported that Silicon Technology used its self-developed single crystal furnace and successfully used the Czochralski pulling method to pull out a 12-inch single crystal silicon rod – although only the first 5cm of this 1.5-meter silicon rod met 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 Technology.
”Fortunately, fortunately, it’s only 30 million, only 1% of 3 billion!”
Kang Chi could only comfort himself in this way, so as not to sleep tonight…
On the night when this text news was released, the Science and Technology Channel also broadcast the video version of this news.
The host conducted a video interview with Dr. Yan Hui, the chief technical consultant of Silicon Technology.
In this interview, the reporter, through Dr. Yan, explained the production process and technical difficulties of single crystal silicon rods to the audience from the basics to the in-depth. At the same time, he focused on the principle and process of the Czochralski pulling method.
”The principle of the pulling method is actually very simple, a bit like the principle of pouring water into ice in our north. As long as the polysilicon is heated to 1,700 degrees in a quartz crucible and melted into liquid, and then the single crystal silicon thin rod prepared in advance is inserted as a seed crystal, and slowly pulled up, a large-sized single crystal silicon rod can be pulled out.”
”Although the principle is very simple, that is, small rods go in and big rods come out, there are many technical difficulties in actual operation, so I won’t elaborate on it here…”
On the TV, Dr. Yan vividly demonstrated the principle of the pulling method with everyone through some small props around him. Even ordinary people can get a general idea after watching it once.
As the interview was coming to an end, the host suddenly changed the subject and asked Dr. Yan another question: “I heard that in addition to the Czochralski method, the suspension method and the floating tape method can also be used to produce single crystal silicon, especially the floating tape method, which has attracted widespread attention in the industry due to three papers in “Electronics and Computers” some time ago. Dr. Yan, what do you think of them?”
Yan Hui was slightly stunned, and obviously did not expect the host to ask this question.
He sorted out his thoughts a little before answering: “I have also read those papers. In theory, there is indeed no big problem, but in fact, the floating tape method has always been controversial in the industry, and silicon wafers cannot be made by writing a few papers.”
”Even Shin-Etsu Chemical, which has conducted the most in-depth research on the floating tape method, has publicly admitted that this technology is not yet mature and there is still a long way to go before practical application.”
The host nodded and continued to ask: “So do you think it is unrealistic for Dahan Silicon Industry to manufacture single crystal silicon rods by improving the floating tape method?”
”Well… at least in the short term, I think The hope of success is somewhat slim, especially when their investment in scientific research funds and talent reserves seem to be far from enough. ”
Faced with the unyielding host, Dr. Yan was also outspoken and expressed his most true opinion, “Of course, according to probability, nothing in the world is absolute. Personally, I still hope that they can achieve a curve overtaking in the floating belt method and break this technical barrier for domestic silicon wafers.”
”Okay, thank you Dr. Yan for the wonderful popular science…”
After the news was broadcast, it soon attracted considerable attention in the semiconductor field.
Before, everyone speculated that there would be a major breakthrough in domestic silicon wafers, and the breakthrough point was in the manufacture of silicon rods.
But after Dr. Yan’s analysis, everyone couldn’t help but doubt it, thinking that Dr. Yan’s analysisThe analysis is not without reason.
After all, in the field of domestic silicon wafer manufacturing, the one with the most say is not Academician Wu, but their Silicon Technology. Of course, it is not ruled out that there is competition among peers and the factor of deliberately belittling opponents is involved.
In short, after the Ministry of Science and Technology issued a document and announced the semiconductor-related policies for this year, the entire domestic semiconductor industry was filled with a strong smell of gunpowder.
Among them, the silicon wafer manufacturing field, which has increased support, is the most.
After all, this field has been sitting on the bench for too long…
Now that it is finally cared for by the top, it is necessary to perform well? In the following period of time, in addition to Silicon Technology, more than a dozen companies and scientific research teams have successively announced their latest achievements, involving multiple links including silicon rod purification, chamfering, slicing, polishing, etc.
Finally, eight companies passed the review of the Ministry of Science and Technology and received a total of 140 million yuan in support funds.
In this way, more than 200 million of the 3 billion yuan special scientific research support was divided.
However, Kang Chi was not panicked,
because he knew very well that these were the results they had accumulated in the past. After this period of time, it would 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 3 billion yuan support fund, it certainly did not intend to issue it all at once…
This was originally a tug-of-war in months or even years.
On January 18, the sixth day of the twelfth lunar month, Gangcheng High-tech Industrial Development Zone.
With the sound of salutes, the groundbreaking ceremony of the first phase of Dahan Silicon Industry began.
On the leveled land, a pre-prepared red background board stood behind the foundation stone, and in front of it were hundreds of invited guests from all walks of life and all employees of Dahan Silicon Industry.
As the chairman of Dahan Silicon Industry and the protagonist of today, Kang Chi was dressed up especially well today, with shiny leather shoes, a straight suit, and neat hair, which was completely different from his casual temperament before.
Kang Chi originally refused, but Zhang Qing repeatedly emphasized the importance of today’s occasion to him.
When he arrived at the scene, he was immediately glad that he listened to Zhang Qing’s words, otherwise he would stand among so many important leaders like a country leopard…
It was indeed unmannerly.
“Mr. Kang, congratulations!”
”Thank you, Vice Mayor Huang. If it weren’t for your full support during this period, our progress would not have been so fast!”
”Haha, it’s my duty, this is our Secretary Yuan and Mayor Lu…”
”Ah, hello Secretary Yuan, hello Mayor Lu, thank you for your honor…”
”No, no, this is a big event in Steel City. As the host, how can we not come?”
”Congratulations, Mr. Kang. I wish your company will continue to innovate and reach new heights in the future…”
”And a lot of money!”
”Haha, thank you for the blessings from all the leaders…”
