At around half past two, Su Yuanshan received a call from the front desk, saying that the leaders of Zheng Gong and his party had arrived.

Su Yuanshan, who was waiting for a little drowsy, immediately woke up.

A line leader?

Su Yuanshan immediately got up, straightened his appearance, and strode out of the office.

His office is located in the fourth room of the entrance, because the layout of the entire floor is mainly based on the use of space, so Su Yuanshan just went out and saw Zheng Zhenchuan who was standing at the front desk and introducing the visitors opposite him as the "host".

Su Yuanshan passed by Chen Jing's office and opened the glass door with one shoulder: "Sister Jing, there are guests coming." ”

"Huh?" Chen Jing saw Su Yuanshan snorting at the door, but he was stunned and immediately got up, and asked as he walked, "What guest?"

"CAS. ”

"Well, then I'll go say hi. Chen Jing immediately understood the intention of Su Yuanshan to call her over - Su Xinghe was not there, nominally she was the supreme leader here, and she came forward to represent the specifications.

At the same time, walking through Qin Weimin's office, Su Yuanshan called Qin Weimin out again.

Over there, Zheng Zhenchuan also saw Su Yuanshan and smiled happily at him.

"Uncle Zheng, you're making a surprise attack. Su Yuanshan was half a position behind Chen Jing, and Lao Yuan quipped.

"No, it's just a casual discussion about something, hello Mr. Chen. ”

"Hello Zheng Gong. Chen Jing pursed her lips and smiled, and immediately looked at the three people who walked out of the rest room, her eyes rolled, and she probably guessed why Zheng Zhenchuan would carry out a "surprise attack".

Among these three people, two of them don't know each other, but Zhou Boguang she knows, and they are all old friends of Yuanxin.

"Hello, Director Zhou. ”

"Mr. Chen is good, Xiaoshan, for the people. Zhou Boguang greeted with a smile and introduced the two beside him at the same time.

Zhao Kaidong is an expert in optical instruments at Changchun Institute of Optics and Mechanics.

Xie Kaiyun is deputy director of the Institute of Semiconductors, Chinese Academy of Sciences.

"Welcome, welcome, welcome to the leaders of the inspection work. Chen Jing shook hands with the bigwigs one by one with a smile that made people feel like a spring breeze.

......

After inviting everyone to the reception room, which had been converted from the original finance room, Chen Jing left under the pretext of excuse.

"Uncle Zhou, Uncle Zheng, I guess you want to conduct a surprise inspection, which caused us to be rude in front of the two leaders. Su Yuanshan relied on his good relationship with the two of them, and he was young, joking.

Of course, Zhao Kaidong and Xie Kaiyun laughed.

After chatting a few words, Zheng Zhenchuan went straight to the point.

As Su Yuanshan expected, Zheng Zhenchuan came to discuss with Su Yuanshan this time how the lithography machine project should go in the future. And this week, Boguang and the three of them are also members of the expert group for this acceptance.

Looking at this staffing, Su Yuanshan understood why in his previous life, without the help of Yuanxin, the lithography machine made by Chengguang could also pass the acceptance - the three leaders of the expert group, two of whom are "relatives" of the Chinese Academy of Sciences, how can they not be accepted?

"The four of us came here mainly to hear Yuanxin's views on the development of domestic lithography machines. Zheng Zhenchuan said with a smile: "After all, your Yuanxin is the leader of the domestic semiconductor industry, Dr. Qin, your CPU is said to have been exported to the West?"

Qin Weimin smiled: "Far sales are not counted, we are taking the design route, and we have only signed two Western orders recently." ”

"That's also a domestic CPU star. ”

"Uncle Zheng, you are exalting us too much. Su Yuanshan said with a smile: "We are just a little bolder, our steps are a little faster, and at the same time, our eyes are not staring at our feet, we just look a little into the distance." ”

Su Yuanshan's modesty made the four bigwigs laugh at the same time, but they soon realized that Su Yuanshan was not saying it casually.

The first two sentences that have already spread all over the land of China are not Su Yuanshan's original, and the latter sentence is his focus.

The leader of the acceptance team this time, Deputy Director Xie Kaiyun, looked at Su Yuanshan with burning eyes: "Xiao Su, how far should you look at the lithography machine?"

"Although the mainstream laser light source in the market is already I-line UV (ultraviolet laser), as far as we know, the light source part has already entered the field of DUV (deep ultraviolet), and it is about to break through the 248nm KrF, and even has begun to study the 193nm wavelength ArF. ”

Su Yuanshan folded his fingers and smiled silently: "At the very least, we need to enter the ultraviolet field." ”

"The i-line UV combined with the high-precision workbench can meet the needs of memory and low-end chips for a long time. And these needs will be long-term. ”

After being reborn for so long, Su Yuanshan can certainly understand more thoroughly why the semiconductor industry has become like this.

More than ten years ago, Wang Shouwu said at the National Conference on Natural Science Disciplines:

-- The total amount of integrated circuits produced by all semiconductor production plants in the country in a year is only equal to one-tenth of the monthly output of a 2,000-person enterprise in Niguo.

The fear caused by this almost suffocating gap has led to the long-term expansion of domestic semiconductor production capacity in the future.

Of course, the spirit of self-reliance is engraved in the bones of the Chinese people. During the same period, China has not given up self-development...... It's just that there is really no way to generalize what the whole country has done.

For example, this lithography machine, which is 92 years old, can still only achieve a yield of about 35% on 2 microns - this is still the result of importing a large number of parts including motors, plus more than half of them are doctoral and master's 50-person CNC team for more than half a year.

Even so, it still represents the most advanced level in China, and it is not an exaggeration to give a gold award.

Su Yuanshan continued: "Since there is a long-term market demand, then we will take a long-term view, grit our teeth, and directly look at the demand that will not lag behind in the next few years or even more than ten years." ”

Seeing that the four of them were thoughtful, Su Yuanshan thought for a while and said, "I don't know if you understand the field of wireless communication. ”

The four of them glanced at each other, but Xie Kaiyun nodded and said, "You say." ”

"At present, the big wave in China is Big Brother, which simulates the network. And only this year's domestic big brother passed the acceptance, right?"

Xie Kaiyun, as the deputy director of the Institute of Semiconductors of the Chinese Academy of Sciences, was much more well-informed, and nodded: "Yes." ”

"Director Xie, if we compare Big Brother's analog system to the first generation of networks, GSM is the second generation. ”

"GSM, the one proposed by the European Telecommunications Standards Organization, right?"

"Yes, now several large foreign companies, such as Siemens, Motorola, and Ericsson, are engaged in it. ”

Xie Kaiyun raised his eyebrows: "You guys are also doing it?"

Su Yuanshan nodded: "Yes, but we are behind them." It is estimated that they will be able to launch finished products in the next six months. And the most optimistic estimates are that we all have to wait a year. ”

Xie Kaiyun and the other three looked at each other in surprise, and after being silent for a few seconds, they smiled and said, "That's also amazing...... It is said that the Ministry of Posts and Telecommunications also has ideas, but it has never been sure what standard to use. ”

"Hehe, there's nothing big about this. What I really want to say is ......"

Su Yuanshan looked around, his eyes were very bright.

"In terms of technology, although GSM is one or two years behind, our research field has entered the third generation, the technical planning has involved the fourth generation, and the far and near considerations have even been looked forward to the fifth generation!"

"If the transmission speed is taken as an example, the second generation is 9.6Kb/s, then the third generation should reach about 5Mb/s, the fourth generation will consider 100Mb/s, and the fifth generation will directly enter the Gb era!"

Xie Kaiyun listened to this almost sci-fi transmission rate, and the whole person felt a little trance.

"We can't catch up with the second-generation standard, and we may not be able to catch up with the third-generation standard, but we will definitely be able to catch up with the fourth-generation and fifth-generation, which is the vision of Yuanxin. ”

Su Yuanshan said calmly.
