Chapter 474 The last board and the tool man
Gao Zhendong stayed at Dongguang Institute for almost seven days. Except for the first two or three days, which were dealing with optical systems, the rest was spent cooperating with Dongguang Institute. Trial production of fused silica glass.
Dongguang Institute also mobilized all relevant forces and resources to pounce in with all its strength.
The reason why we are so excited is because as early as the day after we decided to cooperate to make this thing, the third rolling mill sent the little inventory of Gao Zhendong’s trial production to the flying tractor. In the afternoon of the same day, Dong Guangsuo received it here.
Although I haven't trial-produced it yet, the samples Gao Zhendong has already made can still be tested, at least so I can have some confidence.
After a set of tests, it goes without saying the specific data. Dongguang Institute’s reaction was just one: "Do it! You must learn this thing!"
To their surprise, this thing has a The advantage is that Gao Zhendong himself didn't say it, and Gao Zhendong didn't know it because he didn't have the equipment to test it.
That is, this material not only has good light transmittance around 350nm, but also maintains good light transmittance in most ultraviolet bands. With this one characteristic, the significance of this thing has changed from a supporting material for the optical system of the lithography machine to an important material for the future ultraviolet optical system.
And by adjusting the elements or compounds doped inside, the optical properties can be adjusted. And after this thing is adjusted, even if the working characteristics are similar to existing materials, just a thermal expansion coefficient is enough to satisfy people.
The measured thermal expansion coefficient is 0.3ppm/℃. When used in a small-sized optical system, it means that it does not move at all.
Li Gong took the test report and said to Gao Zhendong: "I'll cover the 5μm you want, and I'll give you a military order, haha."
Their chief engineer also nodded repeatedly: "Yes. , we fully support his military order!”
Party A like Comrade Gao is so good. He not only provides you with topics, but also provides you with ideas, equipment, materials, and even gives you a set of results. , where to find it.
This kind of good comrades and good units must unite well and do their work solidly, otherwise they will feel bad.
With this tone in mind, Dongguang Institute moved very quickly, mobilized all relevant resources and supporting factories, and devoted all its efforts to this matter.
Comrades at Dongguang Institute all understand that Gao Zhendong's time here is limited. Taking advantage of this great opportunity, he will personally take charge of the battle, communicate and provide guidance in person, first make things, and then talk about improvements.
For the time being, we will not make any improvements or optimizations regarding the formula process. We will just follow the requirements given by Gao Zhendong and strive to make a batch of real things by hand within this period of time.
Fortunately, the Northeast at this time had strong technical strength. Otherwise, the gas injection cooling device would not have been completed in a short time. For this, it was still borrowed from other factories. The gas injection devices used for other purposes are just makeshift, but the effect is really not as good as Gao Zhendong's. After all, the device developed by 1761 is a serious and targeted design.
Just the day before Gao Zhendong left, the chief engineer of Dongguang Institute, Engineer Li, Gao Zhendong and others gathered together and looked at the foggy translucent rectangular cube in front of them.
This is the fused silica optical glass that they have been tinkering with for several days. Since Gao Zhendong has already trial-produced it, it means that there is no need for research time at all. They are just making some adjustments based on the existing resources of Dongguang Institute. Just work, so it’s fast.
The regular rectangular shape that looks foggy is very beautiful. Compared with the transparent and bright form, it has a thick and simple beauty.
As for translucency, don’t worry. It will become transparent after cutting, grinding and polishing. Translucency is because the surface of the material is uneven and the reflection and refraction of light are inconsistent. It needs to be filled in or removed. These bumps and valleys will change.
Hot knowledge: Do not splash water on the frosted glass surface of the bathroom window when taking a shower. You can be more casual with the frosted glass film.
Gong Li still felt a little unreal: "Comrade Gao, is this thing completed like this?"
The chief engineer was very calm and respected scientific laws: "You can only say that the trial production of the sample has been completed, but whether it is successful and whether it can catch up with Comrade Gao and his original samples will only be known after testing."
After saying that, he asked the comrades in the office to take samples for testing.
It will take some time to cut, polish and polish this thing.
For dinner that day, Dongguang Institute and Carbon Research Institute invited him to a meal together. Duan Gong was very honest at the wine table.
Let’s just say that Lao Duan is a wonderful person. The wonderful thing lies in these things.
Do it when it’s time to do it, without being vague at all, and be flexible and flexible when it feels wrong, without forcing it at all.
People from both units were here, so there was no need for him to bear Gao Zhendong's firepower.
The next morning, the inspection personnel of Dongguang Institute, who had been busy for a long time and a night, found the chief engineer and Engineer Li of the institute with the test results.
"Chief Engineer, Engineer Li, the results are out!" The inspector was very excited.
"How is it?" The two people who were talking with Gao Zhendong turned to stare at the inspector.
“Some parameters are better than the sample, and some parameters are worse than the sample, but the deviations are within a certain range and can be considered consistent.”
There are some differences in environmental conditions such as equipment and materials on both sides. The deviation caused by such differences is very normal.
"What about the thermal expansion coefficient? What about the light transmittance?" For the matter at hand, these two are the most important. The other parameters are a little more biased and can be adjusted accordingly in the design. Adaptation, such as refractive index.
But these two cannot be adjusted and will directly affect the results.
“The light transmittance is basically the same, the deviation is between 2% and 3% at 355nm, and the thermal expansion coefficient is 0.5ppm.” The injection cooling efficiency affects the amorphous structure, so this change is not surprising.
Hearing this result, everyone breathed a sigh of relief, including Gao Zhendong.
"General Engineer Gao, don't worry this time, we will leave the rest to us." Engineer Li was very excited. The remaining matters included the second phase of the optical system project and fused silica optics. The topic of glass materials is funny to say. This topic has not yet been declared, but the results have come out.
Twelve Machinery Department: I am familiar with this matter, you can just get used to it.
"Okay, then I'll wait for the good news." Seeing that the success rate of this try is getting higher and higher, Gao Zhendong is much happier than them!
In the afternoon, Changji Suburban Airport.
Engineer Li from the Dongguang Institute held Gao Zhendong's hand: "General Engineer Gao, we will adjust the current beam expansion optical system as soon as possible according to your suggestions. We will try to make it available to you from January to February next year." . As for the 5μm micro-projection, don’t worry, we will go all out.”
Through the comrades at the Carbon Research Institute, they at least know that Gao Zhendong is a chief engineer, instead of “Comrade Gao, Comrade Gao” like before. " called.
Gao Zhendong smiled and said: "Then I'll leave it to you. On behalf of the 12th Machinery Department, thank you in advance."
The 12th Machinery Department: Who is it? Just leave it here. Represent us? Oh, Zhendong, it’s okay.
Gao Zhendong Maliao owes a favor to the 12th Machinery Department. As far as the current results of Dongguang Institute are concerned, the last board of the early integrated circuit technology has been completed!
But what he said made the old Duan next to him twitch in his face, "Aren't you from the 17th Machinery Department?" This means that it goes too far.
When he came over, in addition to seeing Gao Zhendong off, he also had something to say to Gao Zhendong.
"General Engineer Gao, although our hospital really can't spare the manpower to do that thing you talked about in our hospital, don't worry, if you want to do it, just give me a shout and I'll be in the hospital. Come here to support me if you ask for leave."
Old Duan quietly said to Gao Zhendong while no one was paying attention.
Unfortunately, the Carbon Research Institute was still unable to find the manpower to work on pyrolytic graphite, even though this thing is most compatible with their profession.
But Lao Duan had a hunch that something that would interest Gao Zhendong so much must be something great. Gao Zhendong will eventually work on this thing. When the time comes, whether it is done at the Carbon Research Institute or not, he will be the one to blend it. It's definitely a good thing.
From Gao Zhendong's words, he has understood it clearly, and he has dealt with Gao Zhendong more and knows Gao Zhendong's style better.
Pyrolytic graphite is good, but it needs to be done by CVD, and he has arranged for someone to do CVD. Institute 1761 sounds like it is the territory of the 17th Machinery Department. It is such a coincidence that someone happens to be doing CVD. ? He didn't believe that there was no trace of Gao Zhendong in this.
Now it seems that everything is ready for pyrolytic graphite. All it needs is the east wind, and the help of graphite people.
As for the research on theory and route, in Lao Duan’s view, with Gao Zhendong’s past abilities and habits, he is definitely confident in doing this. What he lacks is not the core people, but the core people. It is the person who is concretely implemented, commonly known as the tool person.
Lao Duan didn't believe that Gao Zhendong could explain everything about pyrolytic graphite clearly, but he didn't understand how to do it at all?
Impossible! This is not his style.
So he quietly gave Gao Zhendong a head start. This was a big issue.
Gao Zhendong was very happy, Lao Duan had a very bright mind.
“Well, okay, if you have this intention, I will definitely inform you.”
Lao Duan grinned widely, saying that he still had to fight for the opportunity by himself.
Under the greetings of comrades from the Dongguang Institute, the Carbon Research Institute and the local army, Gao Zhendong and his party boarded the plane and rode on the flying tractor for another four hours before returning to the capital.
The time is shorter and the speed is faster than in the past. This has nothing to do with the flying tractor itself. It is mainly because the north wind blows in December, and the plane flying from Changji to Beijing has a tailwind!
Although the wind is not strong, the speed of the wind is still very obvious for an aircraft like a flying tractor. It is so outrageous!
Siting back home in the factory car, it was already the evening of the 24th of the last month of the 1960s. Lou Xiaoe received a call from Gao Zhendong in the morning and was waiting after returning from Lou's house.
As soon as she saw Gao Zhendong, Lou Xiao'e put down the spatula in her hand, cheered and hung it around her neck.
She estimated that Gao Zhendong had not eaten dinner and was preparing it for Gao Zhendong.
While holding her in circles, Gao Zhendong thought: Hey, this day is fine, I will take Xiaoe out for a walk tomorrow.
It’s not that Gao Zhendong thinks this day is a holiday, the main reason is that this day was a good excuse in his previous life. He was used to it, and all boys knew it.
It’s just an excuse to go on a date. As for college students in previous lives, do they really believe that? Damn it, they are more likely to believe in Feitian Pasta Cult than to believe in that stuff.
