In this case, of course, it can''t be true, and everyone has the right to be happy. However, the atmosphere was more active and the goal was achieved.

After all the dishes were served and the wine was ready, the staff of the canteen left. Long Jianhua said, "president Zhang just started and threw out the problems. We talked while eating and talked about the next work ideas."

Zhang Zhongmou said with a smile, "I haven''t finished talking just now. I was attracted by those guys who want to drink. The coming out of this chip means that electronic technology will take a big step forward. Products from computers to mobile phones to digital microwave ovens will be updated. "

Dr. Lin nodded, "there is no doubt about this. Research institutes and institutes, there will be a lot of work to do next. There are a lot of products to upgrade, and even new products appear. "

Lisep swallowed the food in his mouth. "At this point, the research institute has a lot of ideas, and some have even started, waiting for the upgraded chip to appear. You wait. Within a month, you are ready to upgrade your home appliances. "

Liu Zhifei said with a smile, "it''s really sad to be in Chongshi group. New products often appear. When you see a breakthrough in the technical level, you want to change it immediately. We don''t know how many times we have changed our household appliances. "

Zhang Zhongmou laughed, "Professor Liu, your family should take the lead in consumption. You should not only be loyal customers, but also loyal fans. However, this time, there is no need to change it immediately, because it is only a transitional technology. Dr. Lin, Dr. long, isn''t it? "

Dr. Lin nodded, "we only use the simplest liquid this time to test whether this idea is feasible. These things are made by Dr. long. She has chosen some directions and is ready to continue the experiment. "

Junyan nodded. "After calculation, the wavelength in the next step will be lower than 100nm. In this way, the chip processing capacity will be stronger, the products will be more advanced and more powerful. "

The two of them are the main designers of this lithography machine. They speak and the others listen carefully.

She continued, "the process is very comprehensive. The chip can be produced this time thanks to the maturity of supporting technologies, such as ArF excimer laser, photoresist and etching machine, which can meet the requirements; If it is shorter, these supporting products may not be able to meet the requirements. The most obvious is that the etching system and alignment system have higher requirements for precision control. "

"In the next step, our lithography machine needs to be comprehensively upgraded in terms of supporting substrate size range, resolution, alignment accuracy, exposure mode, light source wavelength, light intensity uniformity and production efficiency."

"Among these performance indicators, only the wavelength of the light source has nothing to do with us. The rest are the research contents of our lithography Institute."

"We all experienced the production of 157nm and found many problems. Some of this transformation can meet the requirements of 157nm, but certainly can not meet the requirements of lower wavelengths, so our next task is very arduous. "

Liu Zhifei whispered in long Jianhua''s ear, "Yun Yan''s mouth is a set of professional terms, which seems unfathomable."

Long Jianhua smiled gently, "it''s good for you to run to someone''s professional team and understand a few."

She snorted and sat down eating while listening to everyone

Although neither the research institute nor the group publicized the launch of 157nm chip, there was still grapevine news, which immediately shocked the industry.

At present, ArF excimer laser is used, and its wavelength is 193nm. We have stayed at this stage for a long time; The sudden emergence of 157nm is tantamount to a breakthrough, which means that relevant technologies have made a breakthrough.

This news shocked and excited a large number of people, made some people feel a little sour, and made some people very angry.

The media came to make an appointment for an interview, and the available reply had to wait ten days, because the research team was very busy now.

Of course they are busy.

We should apply for patents here. There are ideas that can apply for patents in the future, and we should also organize the preparation.

Future research will also be discussed. After dinner that night, the whole team had a three-day holiday. These three days were not without tasks, but only free time, but the next project discussion was to be carried out in three days.

This discussion is three days

In the past three days, some people speculated that Chongshi research institute must have adopted F2 excimer laser, which has a shorter wavelength. However, they are also puzzled that this laser has just been invented. Compared with ArF excimer laser, lithography is difficult, expensive and easy to damage. There are still many problems in resist and high-precision alignment.

After the speculation, they were shocked. There are rumors that there will be no fake. Have they solved these problems? Or do they ignore costs and costs in order to produce 157nm chips?

Among peers, some manufacturers soon began to study the application of F2 excimer laser, trying to follow up on the use of the laser, so as not to be left too far by Chongshi group.

Some peers are as stable as Mount Tai and want to pay attention to what process the world group produces 157nm chips

As a latecomer, sometimes it is very sad. If the pioneers don''t publish the technology, their layer of paper can''t be pierced. They can only watch others occupy the market.

As a pioneer, the pressure is also great. It''s OK to invest a huge amount of money in R & D if you can seize the market first and recover the R & D cost; If someone intercepts his beard in the middle, he will lose his money; If you are quickly imitated by others and seize the market, you will be angry and spit blood.

Both Chongshi Research Institute and Chongshi group have done well in this regard, and are getting better and better. Through the daily inspection of legal affairs and security, check and make up the deficiencies where there may be mistakes, and fewer and fewer loopholes can be generated.

The reason why long Jianhua kept a low profile, but was not afraid that others would deal with him through various overt means, was that he made rational use of the law. As long as he is reasonable, he won''t be afraid

At the press conference, global journalists knew a name for the first time - immersion system. When using ArF excimer laser, a set of immersion system is added, so that the 157 nm wavelength can be realized smoothly.

The global chip industry immediately knew the name of "immersion system" and that the light source had not changed.

Those colleagues who soon decided to study the application of F2 excimer laser turned blue when they saw the news; Those who are as stable as Mount Tai, after seeing this news, are glad that they have not made arbitrary decisions.

However, they all thought of a question at the same time, what is an immersion system?

At the press conference of Chongshi Research Institute, there was no explanation of the immersion system.
