Chapter 464: Oh, it’s exceeded?!
If the Russians and the Gallics were depressed, then the comrades in the Ministry of Foreign Trade were celebrating.

As expected of the "No. 1 export earner", this thing is not only easy to sell, but also has a high price and high profit margin.

The countries that bought the DJS-59 did not equip all of them with operating systems, but a quarter to a third did.

A rough calculation based on the price means that the comrades from the Ministry of Foreign Trade sold a small amount of extra money equivalent to about 59% to 5% of the total sales of DJS-6 before. Don't underestimate this number.

To use the Internet jargon of later generations, this is called tapping into existing stock. Anyone who already has a DJS-59 computer is a potential customer, and it does not delay the development of incremental customers.

At the same time, the software has no cost, except for the small reels of tape.

In general, the comrades in the Ministry of Foreign Trade have carried out the no-cost business in full swing and relatively smoothly.

Information technology is more likely to form path dependence, especially after investing a lot of resources in a certain architecture and obtaining a lot of results, it becomes difficult to change.

This situation, in the Internet jargon of the future, is called "ecology."

From the perspective of the early development of PC, the performance of X86 CPU has never been the best, but its combination with the super hardware has made this alliance almost universal. Oh, by the way, the operating system of the super hardware was not the best at that time.

But when it comes to ecology, Gao Zhendong is not working on any productivity software now. Firstly, he does not have that much energy and it is impossible for him to do it. He can only guide others to do it. Secondly, the time is not right yet. He is still waiting, waiting for an opportunity, waiting for a milestone.

There are only two things he is doing in terms of software now.

One is the organization and compilation of the operating system's network protocols, and the other is him making a list, a list of most of the things he himself would not do.

It was already December, and more than half a month had passed since the launch of the 6011 campaign. Gao Zhendong didn't know how others were progressing, but for the more than ten types of steel he himself had completed about half of the processes for three of them, he had already completed about half of them.

One of them was being handled by the people in the third factory under the supervision of the master himself, one was being handled by the AOD branch of the Beijing Iron and Steel Plant, and the remaining one was being handled by people in the factory.

In addition to the one that was accepted in the name of the factory, the Third Rolling Mill also organized manpower and carried out a subcontracting project here at Gao Zhendong. Fortunately, this is not the construction industry, so there is no illegal subcontracting.

Judging from the number of technical personnel and production personnel in the factory, the supply the factory received was obviously not enough. It was a happy thing for everyone to be able to solve the problem with Gao Zhendong.

Gao Zhendong visited the two groups in the factory and checked the situation, but he did not go to the one at Beijing Steel Plant because he did not have time. If he had any questions, he could just wait for them to ask.

Just at this moment, someone came to find him.

It was Yi Zhonghai, who was responsible for leading people to work on the worktable of the lithography machine.

"Chief Engineer Gao, we have finally made the workbench you asked for. Would you like to take a look?"

"That's great, Master Yi, let's go, go!" Gao Zhendong became excited when he heard it. Finally, there was some news about one of the core components of the lithography machine.

Following Yi Zhonghai to their workshop, Yi Zhonghai introduced the general situation as we walked.

In general, this workbench is made purely by hand, especially the micro-motion part. If most of the parts of the macro-motion (coarse adjustment) part are made in batches by their apprentices, then the micro-motion (fine adjustment) part is made by themselves bit by bit, measuring and repairing a little at a time, and measuring and repairing a little at a time.

However, for equipment with high production volume such as lithography machines, manual rubbing is not unacceptable as long as the design and structure are determined.

And this thing is rough, but it actually lasts quite a long time.

A very unpopular fact is that 1~10μm lithography machines are still being used in large quantities, but some are still in the IC manufacturing industry, while others may be used for other purposes, such as PCB manufacturing.

Gao Zhendong developed the photolithography machine not only for the purpose of integrated circuits, but also for photolithography of PCBs, double-sided boards. He combined it with the wave soldering he had done for the Institute of Computing Technology before, and did not require much else. He also tried the automated manufacturing of electronic products.

Yi Zhonghai and his team's workshop is also in the Third Branch Factory, just a few steps away. This is how the work of the Third Branch Factory is. No matter which branch factory or workshop you are originally from, once you take on a job at the Third Branch Factory, in principle you have to go to the Third Branch Factory to complete it, unless the equipment is really impossible to move.

Seeing Gao Zhendong coming in, a group of masters and apprentices looked at him, including Yi Zhonghai's apprentice, Qin Huairu.

This worktable does not use the technology of the worktables that Gao Zhendong had seen in his previous life, such as air floating motors, laser interference and other technologies.

First, there is no such technology, and second, there is no need to use such technology. Those things are prepared for nm-level precision, and Gao Zhendong only requires 5μm now, which is thousands of times different.

The workpiece table looks quite large overall. It is not as simple as a table on a rack with guide rails below. The top is the workpiece table system, the middle is the vibration isolation system, and the bottom is the base. However, the latter two are not strictly speaking part of the workpiece table, but part of the lithography machine.

"Please introduce yourself, Master Yi."

Among them, Yi Zhonghai, an eighth-level fitter, is undoubtedly the leader. On the contrary, there are no professional mechanical designers, mainly because the factory does not have them. Therefore, this thing has to rely entirely on the experience of this group of masters, big and small.

Gao Zhendong named someone, and Yi Zhonghai pointed at the machine and began to introduce it bit by bit. His language was plain, with a lot of jargon from the locksmith and lathe operators. Gao Zhendong had to ask what it meant before he could fully understand it. It felt a bit like reading Internet jargon in his previous life.

The masters also recognized Gao Zhendong's style of asking questions openly without hiding his shortcomings in this area, and they all answered his questions enthusiastically.

After some communication, Gao Zhendong roughly understood the basic route and principle of the workpiece table. The precision required by Gao Zhendong did not exceed the capabilities of the master craftsmen, nor did it involve any fancy tricks or high technology. It was basically precise motion control achieved by the machine tool's deceleration mechanism.

The reduction mechanism is said to reduce speed, but essentially it changes the state of motion in a certain proportion. In fact, it can be used for different purposes, such as torque scaling, size scaling, motion state scaling, etc.

Gears are used for macro movement, and screws are used for micro movement. The master craftsmen of the third rolling mill, through careful design, make the gear sets, screws, etc. cooperate ingeniously to achieve precise positioning of the workpiece table's movement.

It may not be accurate in the future, but it is very accurate now.

For this thing, Gao Zhendong did not require any movement speed, positioning speed, or stabilization speed. This meant that the master craftsmen had less things to worry about and consider when making it, and the goal was both clear and pure.

Those indicators are required for automated production, but Gao Zhendong is not considering that now. Unlike PCB and welding, the entire industry scale of IC is not yet reached, so why produce it so quickly?

First solve the problem, and when the participants gain more experience and confidence, we can continue to improve.

In Gao Zhendong's previous life, the contact and proximity lithography machines that my country developed in 77 were also manual.

Gao Zhendong looked at the workpiece table parameter table in his hand. At this moment, he felt a little bit like what others felt when they faced him.

That's a surprise. I didn't expect something this good, but how come you came up with something this good? I never expected it.

"Master Yi, you have achieved 1.5μm for the moving standard deviation and moving average deviation?" Gao Zhendong said with surprise.

The moving standard deviation determines the lithography line width, and the moving average difference affects the overlay accuracy. These two indicators are what Gao Zhendong values ​​most in this area, while other indicators are slightly behind.

Yi Zhonghai looked at all the masters with pride on their faces.

"Yes, we tried it for a while, and after everyone discussed it, we felt that with the conditions we had, if we worked harder, we could actually do better. So everyone tried their best to find a way to reduce it to 1.5. I think it should be useful to you." The words were simple and plain, but the process must have been very difficult.

Watching Yi Zhonghai operate on the workpiece table and verifying the 1.5μm motion accuracy on the spot, Gao Zhendong slapped his thigh and said, "This is so useful! Masters, let me put it this way, you have achieved the accuracy goal I want to achieve next. It's a big step forward! Thank you!"

After saying that, Gao Zhendong took a step back, bowed to everyone, and then raised his head.

"Masters, I hereby announce that the prototype of the special process workpiece platform project has been basically successful and can be transferred to the next stage of research. Thank you to all participants for their hard work and hard work."

All the masters applauded. Chief Engineer Gao was a really excellent person.

For Gao Zhendong, these two indicators have reached 1.5μm. At least on the workpiece table, it can support a line width process of 5~8μm. This has greatly exceeded the original expectations and accelerated the envisioned progress.

The solution to the workpiece stage means that the mask stage has also been solved. The two are highly similar in structure and function, except that one is for placing masks and the other is for placing silicon wafers. As for the optical system, it is basically immobile. It is very precious. Once adjusted, it should not be moved. It is reasonable to let the mask and workpiece move by themselves.

Gao Zhendong raised his head and called Qin Huairu: "Master Qin, please go to the Third Factory Office and ask them to notify the comrades from the Propaganda Department of the Main Factory to come over."

The reason why he called Qin Huairu directly was because the only people he was familiar with here were Master Yi Zhonghai and his apprentice. It would be difficult to ask Yi Zhonghai to do this kind of errands, so Qin Huairu would have to trouble herself.

Qin Huairu responded and went out. Gao Zhendong smiled and said, "Masters, although there is still a long way to go for this matter, we should at least report this good news well within the factory."
