1991 Starting from the core

At around two-thirty, Su Yuanshan received a call from the front desk, saying that Zheng Gong and his party had arrived.

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

A group of leaders?

Su Yuanshan immediately stood up, adjusted his appearance, and strode out of the office.

His office is located in the fourth room after entering the door. Since the layout of the entire floor is focused on utilizing space, Su Yuanshan saw Zheng Zhenchuan standing at the front desk as soon as he walked out, 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, we have guests."

"Huh?" Chen Jing saw Su Yuanshan pouting at the door. She was just startled and immediately stood up. As she walked, she asked, "Who is the guest?"

"From the Chinese Academy of Sciences."

"Well, then I'll go say hello." Chen Jing immediately understood Su Yuanshan's intention of calling her over - Su Xinghe is not here, and she is nominally the top leader here, and her presence represents the standard.

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

Zheng Zhenchuan also saw Su Yuanshan over there and smiled cheerfully at him.

"Uncle Zheng, you are planning a surprise attack." Su Yuanshan joked as he was half a body behind Chen Jing.

"No, I'm just here to discuss something. Hello, Mr. Chen."

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

Among the three people, she didn't know two of them, but she knew Zhou Boguang. They were all old friends of Yuanxin.

"Hello, Director Zhou."

"Hello, Mr. Chen, Xiaoshan, for the people." Zhou Boguang greeted with a smile and introduced the two people beside him.

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

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

"Welcome, welcome, all leaders are welcome to inspect the work." Chen Jing shook hands with the big bosses one by one with a smile that made people feel like spring breeze.

…

After inviting everyone to the reception room that had been converted from the financial room, Chen Jing left with an excuse.

"Uncle Zhou, Uncle Zheng, I guess you wanted to conduct a surprise inspection, which made us rude in front of the two leaders." Su Yuanshan joked, relying on his good relationship with the two and his youth.

Of course Zhao Kaidong and Xie Kaiyun laughed it off.

After chatting for a few words, Zheng Zhenchuan went directly to the topic.

As Su Yuanshan expected, Zheng Zhenchuan came to discuss with Su Yuanshan how to proceed with the lithography machine project in the future. Moreover, these three people, Zhou Boguang, are also members of the expert group for this acceptance.

Looking at this staffing, Su Yuanshan finally understood why in the previous life, without the help of Yuanxin, the lithography machine built by Chengguang could pass the acceptance inspection - two of the three leaders of the expert team were from the Chinese Academy of Sciences How could his "relatives" not be accepted?

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

Qin Weimin smiled: "Export sales don't count. We are following the design route. Recently we have only signed two Western orders."

"That can be considered the star of domestic CPUs."

"Uncle Zheng, you praise us too much." Su Yuanshan said with a smile: "We just got a little bolder, walked a little faster, and at the same time, we didn't stare at our feet and looked a little further away."

Su Yuanshan's modesty made the four bosses laugh at the same time, but they soon realized that Su Yuanshan did not say it casually.

The first two sentences that have spread throughout the land of China are not Su Yuanshan's original work, but the latter sentence is his key point.

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

“Although the mainstream laser light source on the market is already I-line UV (ultraviolet laser), according to what we know, the light source part has long entered the DUV (deep ultraviolet) field and is about to break through the 248nm KrF, and has even begun to study the 193nm wavelength. The ArF."

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

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

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

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

——The total amount of integrated circuits produced by all semiconductor production plants in the country in a year is only 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 domestic semiconductor policy to focus on expanding production capacity.

Of course, the spirit of self-reliance is engraved in the hearts of Chinese people. During the same period, the country did not give up on self-research... However, there is really no way to generalize what has been developed through the efforts of the whole country.

For example, this photolithography machine is 92 years old and can still only achieve a yield of about 35% at 2 microns - this is after importing a large number of parts including motors, plus more than half of the It is the result of more than half a year of hard work by a fifty-person control team with PhDs and master's degrees.

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

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

Seeing the four people thinking deeply, Su Yuanshan thought for a moment and said, "I don't know if you all don't understand the field of wireless communications."

The four of them looked at each other, and Xie Kaiyun nodded and said, "You tell me."

"Currently, mobile phones and analog networks are popular in China. And only this year has domestic mobile phones passed the acceptance test, right?"

As the deputy director of the Institute of Semiconductors of the Chinese Academy of Sciences, Xie Kaiyun was much better informed and nodded: "Yes."

"Director Xie, if you compare the analog system of Big Brother to the first generation network, GSM is the second generation."

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

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

Xie Kaiyun raised his eyebrows: "Are you doing it too?"

Su Yuanshan nodded: "Yes, but we are lagging behind them. They are expected to be able to launch the finished product in the next six months. And the most optimistic estimate is that we will have to wait for a year."

Xie Kaiyun and the other three people looked at each other in surprise. After a few seconds of silence, they laughed and said, "That's amazing... It is said that the Ministry of Posts and Telecommunications also has ideas, but they have been unsure of what standards to use."

"Haha, this is nothing special. What I really want to say is..."

Su Yuanshan looked around, his eyes were bright.

"As far as technology is concerned, although we are one or two years behind GSM, our research field has entered the third generation, our technical planning has already involved the fourth generation, and we have even looked forward to the fifth generation when considering the long and short term!"

"If we take the transmission speed 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 felt a little dazed when he heard this almost sci-fi transmission rate.

"We can't catch up with the second generation standards, and we may not be able to catch up with the third generation, but we can definitely catch up with the fourth and fifth generations. This is Yuanxin's vision."

Su Yuanshan said calmly.
