1991 Starting from the core

Just when Zhang Rujin started to introduce the current situation of domestic lithography machines, Su Yuanshan interrupted him with a smile.

"Uncle Zhang, at least leave us some thoughts..."

Zhang Rujin was startled. When he saw the bitter smile hanging on the corner of Su Yuanshan's mouth, he also felt bitter, and then smiled and shook his head.

Yes, I really can’t get into this stuff. Once we delve deeper into it, it will inevitably come down to the overall industrial situation in the country, and this issue... is too specific and too heavy, and it is far beyond what Yuanxin can afford and discuss.

Now Yuanxin seems to be at the same level as its foreign counterparts, and is even slightly ahead in some fields. But under foreign technology companies, there is a whole pyramid ranging from basic to mid-range to high-end. Yuanxin, on the other hand, is just a building rising from the ground in a low-rise bungalow - what's more terrible is that many of the technologies and equipment that carry this building are from abroad.

A skyscraper, no matter how tall or magnificent it is built. In terms of stability, it can never be compared with the pyramids.

This is why the divestment of the foundry will have such a big impact on FarCore, and why Su Yuanshan insists on giving priority to the development of the foundry - because its divestiture is to build a foundation and a pyramid for FarCore.

"At the lithography machine, Mr. Zheng gave me a brief breather and said that it has not been affected yet. But he has also prepared for rainy days and increased purchasing efforts." Su Yuanshan shook his head and frowned slightly.

The development of domestic lithography machines has deviated from its original trajectory. It has gone from being silent to now being able to provide 436nm-g-line models that meet domestic demand for 0.8 microns. This is actually good news.

But this also means that it will most likely be technologically blocked in advance.

It should be noted that according to the wavelength and line width, theoretically, the g-line light source can also reach the limit of the 0.25um node. However, due to the wavelength, the more the limit is reached, the more complex the process becomes - today's macrochip The lithography machine has been in the factory for more than half a year, and Huajing is still working on the already mature 0.8 micron process. In addition, g-line photoresist currently only supports up to 0.5 microns, so... its future is unpredictable.

And even for remote cores, process advancement is based on Nikon's i-line 365nm lithography machine, although the theoretical minimum process node is still 0.25 microns. But the advantages of wavelength and linewidth make it easier to reach the node.

In addition, as early as last year, Intel launched the PentiumMMX based on the 0.35 micron process technology, which easily returned to the performance throne and also demonstrated the strong process technology strength of its wafer factory.

According to rumors, Intel’s 0.25 micron process is also making breakthroughs.

In contrast, Deyuan is still fighting a tough battle for the 0.35 micron process.

At the same time, Nikon has adopted the 248nm KrF excimer laser as the light source of the next generation lithography machine, followed closely by the 193nm ArF - the famous DUV. By then, with the help of multiple exposure technology, DUV will increase the process node to the dry lithography limit of 65 nanometers.

Going forward...it is the world of immersion technology.

If there is anything else that can give Su Yuanshan the confidence and courage to face the future of lithography machines, it is probably the "troubled" dual workpiece stage and the currently unsatisfactory immersion lithography technology.

After a few seconds of silence, Su Yuanshan said in a deep voice: "For the country, the lithography machine is a golden treasure that has been raised with great difficulty. It is impossible to just ignore it. We only need to do what we should do."

As he spoke, he waved his hand vigorously, as if he wanted to wave away the haze and fog.

Seeing this, Chen Jing did not hide her distress and said softly: "How about a free discussion?"

"It's okay, next one." Su Yuanshan pursed his lips, then looked at Tian Yaoming, and finally glanced at Li Yinan at the end.

"Technological blockade, in addition to prohibiting the introduction of technology, also includes policies that prevent the expansion of our technology and products. Wireless communication is the future development trend and even the future direction. This is already recognized by the world - even our country has begun to establish It’s the Ministry of Information Industry.”

"So, what do you think of the communications department?"

Tian Yaoming, who was always known for his optimism and cheerfulness in Yuanxin, also frowned at this time. He pursed his lips and said nothing, but leaned out and glanced at Li Yinan.

Li Yinan understood, coughed slightly and said in a deep voice: "As far as communication technology and standards are concerned, we have initially completed the construction of patent barriers, and at the same time, we have also reached the intersection of corresponding technologies with Qualcomm, Ericsson and other communication technology companies in advance. Authorization. It can be said that in the field of communication technology, we are not afraid of any blockade. In fact, because we own the core patent of power control, we can also restrict others."

Su Yuanshan nodded and motioned for Li Yinan to continue.

"But if the Japanese are really shameless and want to interfere with our overseas expansion, then..." Li Yinan said with a bitter smile: "Mr. Shan, even if you beat me to death, you can't think of anything to do."

Li Yinan's words made the previous heaviness a little bit lighter - there was finally good news.

"And isn't there a saying going around now that infrastructure like base stations, which are related to a country's national communications, covering a single place is equivalent to setting up a technological colony... If you really want to do this, we're afraid of it just by us. It’s not possible.”

Su Yuanshan smiled, and then he knew that he had asked the wrong person - he should ask Chen Jing.

So he signaled Li Yinan to end his speech and turned to Chen Jing: "Mr. Chen."

Chen Jing's words were concise and concise: "Four words - give in profits and take the lead."

"In the past few years, we have been building base stations in countries around Southeast Asia. We have cooperated with telecommunications companies in various countries through joint ventures, equity participation, extending payment terms, and providing subsidies. A total of more than 5,000 base stations have been built. Thanks to the surrounding The economic development of various countries has now initially recovered the cost.”

"As for other regions..." Chen Jing took a sip from her water glass and continued: "Last time I went to Europe, I communicated with the heads of telecommunications companies in various countries. From the current point of view, European countries generally still have a certain attitude toward our technology. Hesitation. Not to mention that they also have established telecommunications equipment giants such as Nokia and Ericsson."

"So, if we want to enter the markets of developed countries, we still have to rely on technological breakthroughs - it would be much easier if we had technology that others did not have and became the only option."

"In addition, we can block the export of our equipment, but we cannot block our patent authorization and charging. Therefore, I suggest that the R\u0026D center needs to make a comprehensive statistics on all our current technical fields and processes and list which technologies Which technologies are leading or even dominant; which technologies can catch up and achieve independent property rights; which technologies exist dependent on foreign technologies. After statistics, based on future development, we will focus on attacking certain areas to expand our advantages. , complete autonomy.”

"When that time comes, even if our products can only rely on the domestic market, our technology can enter the world - let's take advantage of the patent headquarters, right?"

After Chen Jing finished speaking, several technical bosses nodded.

Yuanxin is restricted mainly by the introduction of equipment and the backward basic industry in the country. When it comes to those areas where intelligence is a competition, Yuan Xin has never failed.

——You know, this is known as the Little Science Academy and is known as the Turtle Reception Office. Every year, it grabs almost all the best semiconductor and computer-related graduates in the country who are willing to enter the enterprise. It attaches great importance to technology research and development. Yuan Xin is so insane!

Today's Yuanxin is a technology enterprise supported by the wisdom of the whole country!
