Traveling through the sword to engage in military industry.

The sale of several ships cannot be finalized all at once, and it is certainly not something that can be done by just Li Yunlong and Kalias.

Li Yunlong's idea was just an intention. After being taken back by Kalias, the Athens Navy would first discuss it internally and form a unified opinion before reporting it to a higher level for decision-making. Then there would be rounds of formal business negotiations, which could take as short as a few months or as long as several years!

By the time the deal is done, perhaps the new generation of destroyers of the University of International Business and Economics will be launched in large numbers.

However, there is no doubt that the idea of ​​having the strongest squadron in the Mediterranean really struck a chord with Athenian naval commanders like Callias.

Their budget meant that they would not be able to have a large navy, but the responsibilities of the Athenian navy, which had vast territorial waters, required them to have a very capable navy, otherwise their maritime interests would not be guaranteed at all.

In this regard, the Athenian navy had no choice but to become stronger, otherwise they would not be able to speak tough words on the ocean.

Li Yunlong didn't have too many thoughts on this. After Wang Peng reported the process of Li Yunlong's negotiations with Kalias, the answer given by the headquarters was to wait and see. They didn't need to worry about the follow-up, and naturally other teams would take over the subsequent negotiation work.

There was neither opposition nor agreement with Li Yunlong's proposal.

Anyway, Li Yunlong’s opinion doesn’t count in this matter, and the suggestion he gave is just a possible suggestion.

The fleet stayed here for three days, and Li Yunlong and Wang Peng also visited the Athens Navy with their team.

Apart from the King of Macedonia and the Island, which are somewhat interesting, the rest of the ships are really not that interesting. In the eyes of Li Yunlong and others today, the only advantage of these three World War II heirloom battleships is that they are big.

In terms of combat power, it is completely incomparable with the Luhai-class destroyer. In the eyes of an outsider like Li Yunlong, a battleship with only naval guns and a modified maritime warning radar would probably be killed before it even sees the Luhai-class destroyer!

However, Li Yunlong still understands the human relations of mutual flattery in business, and he still praises the Athens Navy very highly. Anyway, Li Yunlong can praise it for you for something that doesn't cost a penny.

After the social event, the fleet continued its voyage.

In the far east, Ren Zhong was quite pleased when he saw the results of the computer conference. Although it was the help of old acquaintances, the atmosphere of the entire conference and the extension of the application scope were more in-depth than he had imagined. Many computer companies of Dongda University also reached some cooperation agreements with some professional application companies overseas.

Although there may not be immediate results in sales, Ren Zhong knows that these professional applications are of great value. In the future, the premium for computer applications in these fields will be very high. At the same time, these fields will also be the areas that Dongda will focus on developing in the future. It is also a good thing for Dongda’s computer company to be able to participate in and accumulate some experience now.

According to this development trend, the speed of computer promotion will probably be much faster than the historical time and space of the main world.

Therefore, Ren Zhong was relieved about the promotion of computers, and began to focus on the purchase of computer manufacturing process equipment in terms of computer development. The first generation of chip manufacturing was still too rough, and both the wafer production and CPU processing needed to be improved.

The equipment required for the first generation of NMOS technology mainly includes oxidation furnaces, deposition equipment, photolithography machines, etching equipment, ion implanters, cleaning machines, chemical grinding equipment, etc. The yield rate of these early equipment in the wafer manufacturing process is not good enough, which leads to the high cost of producing 8080. More importantly, the mainstream process of CPU manufacturing in the future is CMOS process. Integrated circuits produced by CMOS process have many advantages such as low power consumption, high speed, strong anti-interference ability, high integration, etc., and practice has proved that only CMOS process can become the mainstream process technology of large-scale integrated circuits in the future.

So after Ren Zhong returned to the main world, he was almost immersed in the transportation of technical data related to CMOS process and the manufacturing design of equipment related to CMOS process oxidation, deposition, lithography, etching, ion implantation/diffusion, etc.

This is a big job, as a set of lithography equipment involves so many things.

Even for the University of Tokyo in the main world, it is a huge project.

第一代的NMOS工艺相对来说还是简化版本，毕竟工艺相比接下来的286/386/486来说还是太粗糙了。一颗典型的286微处理器集成13万只晶体管，一颗典型的386微处理器集成27.5万只晶体管，486微处理器集成120万个晶体管，但是8080才只有6000个晶体管！

This is an order of magnitude improvement.

所以从8080微处理器升级到286微处理器就有一道工艺跨越的横沟！从工艺的精度直观来说，8080微处理器需要的制作工艺是6微米，到了486微处理器制造工艺要达到1微米！

This was a huge test for Ren Zhong. He needed to move tens of thousands of documents, which was totally unrealistic to do on his own.

However, the high cost of chip production lines, even if Ren Zhong has made billions of dollars in the main world by tinkering with some famous calligraphy and high-end jadeite in the world of Sword, but for the chip supply production line, this amount of money is nothing, although it is enough to buy some expired production lines. But the equipment purchased now is still far beyond the level that individuals can afford. After all, it is difficult to buy real old equipment.

The prototype of the step-by-step photolithography machine that currently supports the production of 8080 was developed by the 1985th Institute of the Ministry of Mechanical and Electrical Engineering of the University of Tokyo in the main world in 45. It was the production data obtained by Ren Zhong through computer history archaeology. This was the first step-by-step projection photolithography machine of the University of Tokyo, which used a 436-nanometer G-line light source and basically reached the 5-micron processing technology level.

The maximum evolution of the 436nm G-line light source is about 1 micron. This is the direction of the optical research center's efforts to study iterations. The next node is 3 microns, which is basically prepared for 286-level CPUs. The 1 micron after that is mainly prepared for 386-level and 486-level CPUs. According to Ren Zhong's plan, this is the goal of the fourth and fifth five-year plans. When the 70s of Liangjian design come, let the people in the Liangjian world use 486 computers that can be connected to the Internet.

To further develop, it is necessary to introduce new technology routes, adopt the second generation i-line stepper lithography machine, and use the 365 nanometer i-line light source (mercury lamp wavelength 365nm). The line width of the i-line lithography machine can reach 0.25 microns, and the minimum is 0.15 microns. Such lithography machine technology can basically be used on Pentium 3-level microprocessors. This was the focus of development from the Sixth Five-Year Plan to the Eighth Five-Year Plan, which enabled the world of Liangjian to enter the early stage of the information age in the 80s and begin to develop the first generation of the Internet.
It’s not that Ren Zhong doesn’t want to achieve leapfrog development, but the conditions really don’t allow it.

Not only are these early lithography machines not available for purchase, even if they were purchased, there is no way to transport them to the world of Bright Sword, so everything has to be developed little by little from the basics in the world of Bright Sword. However, in terms of the technical route of development, Ren Zhong will guide them on a path that is destined to succeed.

Telling them the real path, the key technologies involved, and the general research direction of the new materials involved can accelerate the speed of technological iteration in the world of Bright Sword.

But it cannot replace their efforts. After all, these things also touch upon the absolute blind spot of knowledge for Ren Zhong!
However, the benefits of starting from scratch will eventually show up, and the engineering experience gained through early research will be very helpful in subsequent developments. Theoretically, if the G-LINE production process is completed, and after in-depth iterative optimization and exploration of this process, a complete set of research experience is mastered, then there will be a huge advantage in studying the I-LINE production process. After all, most things are universal, but further exploration is needed in terms of precision.

Now that the G-LINE production process equipment has been successfully developed, due to the lack of experience in the initial production of wafer-based integrated circuits, the success rate of burning is not high, resulting in very high costs. However, with the continuous accumulation of production experience, the production yield rate has begun to rise continuously, and now it has increased to about 75%. The advantages of large-scale production are highlighted.

If the current G-LINE production lines run at full capacity, the monthly production capacity can reach 100,000 units. According to the current sales forecast, this capacity should be sufficient to cope with the situation.

However, Ren Zhong required that the iterative optimization of the production line should not stop, because in the design drawings of the next-generation microprocessor 8088, the number of transistors integrated into a single CPU has reached 29000! Nearly five times more than the previous generation! According to the production experience of the main world, it takes a 3-micron production process to meet the needs of so many transistors concentrated on a wafer, so the G-LINE production line must be further iterated and optimized to the 3-micron level to produce such a microprocessor.

In this way, by following the technical route of CPU development in the main world, Ren Zhong can keep Dongda University's computer development at the leading level until the DUV lithography machine era when he can no longer obtain much technical information.

The DUV technology of lithography machines is highly confidential in the main world. Apart from ideas, Ren Zhong has basically not brought much new to the world of Bright Sword in this regard.

However, Ren Zhong is not too concerned about these. If he can achieve 0.15 microns, his mission in the world of Liang Jian will basically be completed.

This is at least 30 years ahead, and those behind are still unable to catch up, so we really can't blame Ren Zhong for not working hard.

In fact, the current research and development environment for the Bright Sword world is almost the best of both worlds combined!

Although there are not many scientists who have made a fortune in the world of Bright Sword, after all, among the company shares given out now, technical experts and management teams only hold 20% of the shares in total.

Compared with the entrepreneurship of technical experts in the main world, this stock is shared by many backbones, and the abilities of super-rich people have long been relatively poor.

But in Ren Zhong's opinion, now is not the time to artificially create super-rich people. Even for him, who has countless core patents, if he relied on these to buy shares and get dividends, Ren Zhong would have already been the undisputed richest man in the world of Bright Sword.

However, Ren Zhong did not do so. The income from these patents is basically tied to the major research centers that produced the research results. These serve as long-term channels for obtaining future research and development expenses.

Only in this way can Ren Zhong continue to maintain the Dawn Research Institute with hundreds of thousands of people without any government funding!

It can be said that the Liming Institute has never asked anyone for funding. Such an environment is undoubtedly very friendly to scientists. They do not need to write countless documents and beg for funding from everyone.

In terms of personal treatment, these scientists receive the best treatment in the country, and housing and family arrangements are also a priority. However, this funding is all earned through a virtuous cycle by the Liming Institute, and a large number of technical staff apartments have been built around the institute through allocated land.

Any researcher who gets married has already started living in a modern two-bedroom or three-bedroom standard house early on.

Even students who have just graduated and entered graduate school have an independent one-bedroom apartment to ensure a good living environment.

The project leaders and core technical backbones of important subjects are now able to buy cars such as Golf and JETTA after receiving dividends!
You have to know that most officials above the rank of county head do not have the ability to buy a car.

This is the best time to be a scientist!

Moreover, in society, the technical staff of the Dawn Research Institute also have a unique status. Whether it is in front of relatives or friends, this is the best job at the moment!

none of them.

Therefore, Ren Zhong has laid a solid foundation. The next step is to continue moving forward according to the technical route he provided to catch up with or even lead the world.

The future world will sooner or later be an information-based world. Ren Zhong has devoted most of his energy to this, which may seem incredible to some people. But now not many people can force Ren Zhong to do anything. Even if Ren Zhong doesn't do anything, he is still a unique scientific giant in the world of Bright Sword.

Investing huge amounts of energy in helping Todai take the lead in informatization is not just an economic issue.

In Ren Zhong's eyes, once a rapid breakthrough in computer technology is achieved, it will have a huge impact on other aspects.

The popularization and performance improvement of computers have had a leapfrog impact on many aspects. For example, with the use of computers for accounting, the statistics and reporting processes that were originally very cumbersome and time-consuming can now be completed quickly through computers.

When it comes to applications that require large amounts of data to perform calculations, nothing is better than computers.

Such an improvement is a revolutionary change in terms of financial efficiency!

No matter how capable an accountant is, he cannot be as fast and accurate as a computer!
