1991 Starting from the core

Joint Research Center for Lithography Machines.

Su Yuanshan was called here directly by Zheng Zhenchuan's regular phone call - during the call, Zheng Zhenchuan just said that there was friction between the light source team and Lin Benjian's team in Silicon Valley.

At that time, Su Yuanshan was so scared that he went downstairs, grabbed a bicycle and rushed to the light source laboratory.

But when he heard the so-called friction, he was slightly relieved.

…

"You mean Lin Benjian said that according to his technical intuition, KBBF crystals cannot be used in DUV light sources?" Su Yuanshan looked at Zhao Kaidong and asked.

Zhao Kaidong was smoking cigarettes one by one and nodded: "Yes, but KBBF's frequency doubling technology has appeared abroad... We have also made a breakthrough here."

Su Yuanshan pursed his lips and frowned deeply. He knows that KBBF can now be exported, and the country is even actively providing it... hoping to share technology with foreign countries.

"Does Lao Lin just have an intuition?"

"No... judging from the existing light sources, KBBF crystal is not enough to meet the continuous, high-power laser output of the lithography machine." Zhao Kaidong looked at Su Yuanshan: "But we believe... high power is definitely possible."

Su Yuanshan sighed softly: "Of course I believe it too..."

Su Yuanshan knew that KBBF has never been used in lithography machines in later generations - in other words, it is more mainstream. When he asked Zhao Kaidong to work on KBBF, he was just lucky, hoping to achieve a breakthrough from KBBF, thereby breaking the shackles of 193 nanometers in one fell swoop. Coupled with the immersion method, it would be easy to use DUV to explore the 5nm process. under.

Now being directly opposed by Lin Benjian, an optical master, Su Yuanshan really didn't know how to judge for a while.

But one thing he believed in was that KBBF's technology would definitely be useful - learn about high-power lasers.

After pondering for a long time, Su Yuanshan said softly: "In this way, Lao Lin's team... has limited investment and must also take into account policy factors under extreme conditions. Therefore, we cannot put eggs in one basket. We still use two The form of walking on two legs.”

"The recruitment season for colonels is coming soon. Yuanxin is also recruiting a group of postgraduate students in optics. You can also apply to Yuanxin."

Zhao Kaidong also sighed lightly.

As a technical person, of course he sees technology and breaks through difficulties when he sees them. But he also knew that Su Yuanshan was in trouble. If KBBF really couldn't be used in the lithography machine, then the money Su Yuanshan invested would be wasted...

Yuanxin is an enterprise no matter how you say it. It is not a good habit to run a business when it is clear that a big boss has suggested that this road will not work and then rush forward instead of being more cautious.

"Okay, then let's walk on two legs."

"Well, then I'll leave it to Uncle Zhao."

Su Yuanshan said and turned back to Zheng Zhenchuan: "Uncle Zheng, how is the situation here?"

"We are doing very well here. All the ordered parts have been approved. It is estimated that they will be available within three months." Compared with Zhao Kaidong, Zheng Zhenchuan is in a much better mood. The lithography machine he designed uses It is ultraviolet light, which can theoretically handle the 0.5 micron process.

Hearing this, Su Yuanshan felt much better: "The first step of the Long March has come."

"Yeah, this is just the first step... I don't ask for mass production quality, I just want stable operation." Zheng Zhenchuan said with a smile.

The lithography machine that Yuanxin dragged from Chengguang is indeed a bit difficult to describe. After constant debugging, it can barely complete its mission - to be able to manufacture components with a 1-micron process.

But that's all. If you want to make money from it, you can't even think about it.

Therefore, Zheng Zhenchuan's current requirements are not high, as long as it can be stable, and then he will start striving for the launch of the next one, and then strive to catch up with the mainstream for the next one.

After leaving the office, Su Yuanshan checked the time. He was too embarrassed to talk to Lin Benjian, so he returned to the office and sent Lin Benjian an email to ask about the situation.

The next day, Lin Benjian replied to the email and used a lot of techniques and theories to tell him that KBBF is a nonlinear deep ultraviolet crystal, which is very good... and according to the existing technology, the conditions of KBBF are not yet satisfactory for lithography machines. needs. I don’t know what will happen in the future, but now it may not be the most suitable light source for lithography machines.

So Su Yuanshan had no choice but to tell him and let him proceed according to his own thinking.

(According to ASML’s engineer’s reply, KBBF does not match the light source of the lithography machine. In fact, I mainly want to be more rigorous when writing this paragraph...)

…

May passed quickly.

In this month, Duan Yongping began to officially lead the promotion of Yuanxin mobile phones, and it was the kind of promotion that seemed calm but was actually an undercurrent.

He first applied for the trademark brand Vidoo, and then invited the popular international movie star Schwarzenegger to endorse the mobile phone - these were all preliminary actions.

You know, Vidoo has just completed the final version, and even the engineering machine has not yet been released.

At the same time, he has been keeping an eye on the factory and solved many production problems with the technicians he brought over, which improved the efficiency of the production line.

It can be said that this person is really a talent.

Then, Professor Su Xinghe, who had been waiting for a long time, finally received an invitation from the capital.

The Chinese Academy of Sciences has officially received approval from the National Academy of Sciences to establish a new National Academy of Engineering, and Professor Su Xinghe is the only first batch of "new" academicians.

It needs to be explained here that in later generations, some people generally believed that the Chinese Academy of Sciences was superior to the Academy of Engineering... If we simply look at the date of its establishment, this is indeed the case. But in fact, the selection rules of the Chinese Academy of Sciences are too strict, and therefore particularly unfair to engineers who have made great contributions to engineering.

Under such circumstances, a group of people with lofty ideals at the Chinese Academy of Sciences have been working hard since the late 1980s, hoping to establish an Academy of Engineering. The academicians of the Academy of Engineering are mainly engineers.

It can be regarded as a kind of reward.

Moreover, in order not to make people think that the "grade" of the Academy of Engineering is low, a considerable number of the first batch of academicians of the Academy of Engineering came from the big guys of the Academy of Sciences!

So there were only thirty "Academicians of the Two Academies" at the beginning. They were both academicians of the Academy of Sciences and the Academy of Engineering, not for "an extra glory", but entirely to establish the "powerful character" of the Academy of Engineering.

As for Professor Su Xinghe, being able to be among the first batch of academicians of the Academy of Engineering, which is unprecedented in the world, means... that he is actually qualified to enter the Academy of Sciences.

But because his major was in the direction of integrated circuits, he was "deprived" of the "glory" of being an academician of the Chinese Academy of Sciences, and was given the honor of being one of the first academicians of the Academy of Engineering.

For Su Xinghe, he is very satisfied to be able to stand alongside so many seniors and even idols.

Su Yuanshan is also very satisfied...

However, Su Yuanshan also has a small wish...

He also wants to become an academician.
