After rebirth, I started a life of attributes

Chapter 210 The photolithography machine is completed and the elbows have "secret talks"

"Secret Research Base".

Chen Feng looked at the mini lithography machine that he had spent a lot of effort to build, but it could not operate because the "optical X-ray" accessory in the optical system was damaged, and he looked sad.

"The X-ray accessories were damaged, causing the entire optical system to become abnormal and unable to allow the lithography machine to operate normally."

"What's even more annoying is that the "optical X-ray" accessories are not available on the market at all. Chen Feng, what are you going to do? Or give this lithography machine to the school and let the school complete the final startup."

Li Nian pushed up his glasses, looked at Chen Feng who was meditating, and then gave what he thought was the best solution at the moment.

"Leave it to the school, no." Chen Feng shook his head, unwilling to hand over the mini lithography machine he had worked so hard to develop to the school.

"Since the optical X-ray parts are damaged, we need to find replacement parts, or we can produce an "optical ""

Chen Feng smiled at his friend Li Nian, cheered up, and started tinkering with accessories to replace the "optical X-ray".

Now that the solution was clear, Chen Feng immediately started looking for new accessories to replace the "optical X-ray" accessories, but there were none on the market. He consulted relevant domestic and foreign scientific research institutions and manufacturers, and even went on the "dark web", but could not find any "optical X-ray" accessories for sale.

Although it has been known for a long time that various countries have strict control over high-end technical accessories such as "optical Removed from an obsolete old photolithography machine.

Therefore, this time he also had a fluke mentality, hoping to find an obsolete photolithography machine, and then remove an "optical X-ray" accessory from the obsolete photolithography machine.

Unfortunately, Chen Feng searched all the channels at his disposal and was unable to find a second photolithography machine that had been eliminated for sale.

So the idea of ​​dismantling the old "Light X-ray" accessories and converting them into new "Light X-ray" accessories was shattered, so I had to make a replacement myself.

Making replacement accessories is a complex and "huge" troublesome process. Chen Feng alone cannot create an "optical X-ray" replacement accessory from scratch.

Since one person can't do it alone, then bring over Li Nian, a "hateful person", as a worker, work for him, and help him make "X-ray" accessories.

……

"I knew you started to have ideas for me from the moment you called me over."

In the "secret research base", Li Nian, whose hands were covered with engine oil, was tinkering with Chen Feng's mini lithography machine while complaining about Chen Feng.

In order to create new accessories to replace the "X-ray" accessories, Chen Feng decisively called Li Nian, and the two worked together.

The two began working together to create new accessories to replace the "light X-ray" accessories. They first conducted a large amount of literature research and understood the working principles and key technologies of optical X-ray accessories. They then designed a new accessory solution based on their research experience.

After the new accessories are designed, the next step is production.

In order to create accessories that meet the requirements, Chen Feng and Li Nian first have to solve the problem of materials. They collected information on various advanced materials at home and abroad through various channels, and finally selected titanium alloy with good optical properties and corrosion resistance as the basic material.

Next, they have to address issues with the manufacturing process. Since photolithography machines require extremely high precision, the manufacturing process of accessories must also be very precise. Chen Feng and Li Nian referred to advanced technologies in related fields at home and abroad, combined with their own rich experience and repeated trials, and finally successfully developed a fine processing technology suitable for titanium alloy materials.

After solving the material and process problems, Chen Feng and Li Nian began to make accessories. They use advanced CNC machine tools and carefully perform processing according to pre-designed drawings. After a week of hard work, they finally succeeded in creating an accessory that looks exquisite and is dimensionally accurate.

However, this is only the beginning of the manufacturing process. In order to ensure that the performance of the accessories can meet the operating requirements of the lithography machine, Chen Feng and Li Nian also need to conduct a series of performance tests on the accessories. They used various advanced equipment in the laboratory to test the optical performance, corrosion resistance, high temperature resistance and other aspects of the accessories. After repeated testing and adjustments, they finally found to their satisfaction that the performance of this accessory fully meets the operating requirements of the lithography machine.

However, when they installed this new replacement accessory on the lithography machine, they found that it did not work properly. This made the two of them feel very confused and puzzled.

All the data of the new accessories are obviously fine, so why can’t the photolithography machine still operate normally?

"It shouldn't be...!"

Chen Feng fell into deep thought as he looked at the words "System Abnormality" displayed on the system page of the lithography machine.

"It stands to reason that the replacement accessory we made is completely fine and can completely make the machine run smoothly. Why is it still not working properly now?"

Li Nian on the side looked at the four words "system abnormality" on the mini lithography machine operating system display and fell into deep doubts.

Neither of them understood what was wrong and why the new accessories could not make the mini lithography machine run normally.

After checking again, it was found that the new accessory was not functioning properly due to the mismatch between the new accessory and the optical system of the mini lithography machine.

They decided to improve upon the new accessories. After they analyzed the reasons for the failure of the new accessory, they modified the design and then manufactured a new accessory again. However, this new accessory still doesn't work properly.

The progress of Chen Feng and Li Nian has reached a bottleneck. They were confused and didn't know how to solve the problem. However, by chance, Chen Feng discovered a technology called "optical micro-DX", which can create nanometer-level microstructures.

Chen Feng immediately realized that this technology could be used to create replacement accessories for "optical X-rays". He excitedly told Li Nian about this discovery. After Li Nian learned more about the "optical micro-DX" technology discovered by Chen Feng, he also believed that the "optical micro-DX" technology could completely solve their current problem of unsuitable accessories.

Therefore, Chen Feng and Li Nian began to study "optical micro-DX" technology and tried to apply it to the production of "optical X-ray" accessories. They spend their days and nights in the laboratory researching, constantly improving technology, and constantly trying. After countless failures, they finally succeeded in creating a new accessory that could replace the "optical X-ray" accessory.

The new accessory was installed on the one-nanometer lithography machine. After testing, the machine can operate normally, and its performance even exceeds the original "optical X-ray" accessory.

"It was finally successful." Looking at the mini lithography machine running smoothly, Chen Feng had a bright smile on his face.

"Yes, it always succeeds. If it doesn't succeed, I won't play with you anymore."

After the new accessories ran smoothly, Li Nian, who loved cleanliness, hurriedly wiped his oil-stained hands with a rag, and then breathed a sigh of relief.

"Isn't it a success now? So all the previous companionship was worth it."

Chen Feng smiled and glanced at Li Nian, who was complaining to him, and thanked Li Nian for his "company" and helping him complete the manufacture of such a great mini lithography machine.

"If you don't treat me to twenty pickled pork elbows, you'll be sorry for me, don't you know?"

Looking at the lithography machine in operation, Li Nian was smiling, and then asked Chen Feng for the "overtime pay" he paid for the machine - twenty elbows.

"Twenty pork elbows, no problem. Don't say twenty, even if it's two hundred, I'll take it!"

Chen Feng readily agreed to Li Nian's request to treat him to twenty sauced pork elbows. After all, Li Nian did help him a lot during this period, so treating him to a meal is a must.

Besides, even if Li Nian doesn't have the time to help Chen Feng, as a close friend, it's absolutely fine for Chen Feng to treat Li Nian to a big meal occasionally. With Chen Feng's financial resources, a big meal is an easy thing.

However, now Chen Feng's financial resources have shrunk by more than half due to the development of mini lithography machines.

In order to develop the current mini lithography machine, Chen Feng almost overdrafted his own funds. The "Fengsu" brand almost went bankrupt because of Chen Feng's misappropriation of funds.

Fortunately, the "Fengsu" brand has an excellent reputation in the sports market. Chen Feng casually designed several new sports products, which sold out as soon as they were launched on the market, allowing "Fengsu" to survive the financial shortage.

Of course, Chen Feng's funds in "Fengsu" alone were far from enough to manufacture a mini lithography machine, so Chen Feng used his trump card and sold all the stocks that he had speculated on the stock market a long time ago. Cashing out almost 7 million was enough to fund the research and development of the mini lithography machine.

It can be said that after the successful development of this mini lithography machine, Chen Feng is actually extremely poor and has basically no money on hand.

Even if you want to change an Apple worth [-] to [-] yuan, you have to think carefully before changing it.

Fortunately, sauced pork elbows are not expensive, so it’s no problem to treat Li Nian to two hundred.

……

restaurant.

Chen Feng and Li Nian were sitting in the innermost box of the restaurant. There were dishes on the table that were full of color, flavor and flavor. The most eye-catching one was the bright red pork ribs in sauce. This is the signature dish of this restaurant. It uses the most traditional preparation method and takes three days and three nights. It is delicious, fat but not greasy. It is the favorite dish of Chen Feng and Li Nian.

Sauced elbow is a traditional Chinese delicacy. It uses pork elbow as the main ingredient and is made through multiple processes such as stewing and sauce making. This dish is delicious in color, aroma and taste, fat but not greasy. It is one of the favorite delicacies of many people.

To make soy pork knuckles, the pork knuckles are first stripped of hair and bones, then simmered in water, taken out when cooked, and rinsed with cold water. Then, put the elbow into the pot, add the prepared sauce, and simmer slowly over low heat until the elbow is cooked. Finally, take out the stewed elbow, let it cool, cut into thin slices, and serve on a plate.

The key to sauced elbows is the preparation of the sauce. Generally speaking, sauces are composed of a variety of seasonings, including soy sauce, cooking wine, rock sugar, pepper, aniseed, cinnamon, etc. These seasonings are mixed in a certain proportion to make a thick sauce, which is then poured into a pot and simmered with the elbows.

The taste of the pork elbow is delicious, fat but not greasy. This is due to the meaty characteristics of the pork elbow itself and the penetration of the sauce during the stewing process. Pork knuckles are rich in protein, collagen and other nutrients, which help strengthen physical strength and improve skin elasticity. The various seasonings in the sauce can increase appetite and promote digestion.

Of course, while enjoying the delicacy of sauced elbow, you should also pay attention to eating it in moderation. Due to the high fat content of pork knuckle itself and the sauce absorbed during the stewing process, the calories are relatively high and it is not suitable for excessive consumption. Eating braised pork elbows in moderation can satisfy your appetite without putting a burden on your health.

Therefore, friends who like to brag should never imitate Li Nian's behavior of eating twenty soy elbows!
  Chen Feng and Li Nian swallowed as they looked at the delicious and tasty sauce pork elbows on the table.

Then, the two raised their glasses, and Chen Feng said: "Lao Li, thank you for helping me during these years. Without you, I might not have been able to persevere. Today, we want to celebrate."

Li Nian smiled and raised his glass: "You're welcome, you're welcome. What kind of friendship do we have? Besides, I'm also interested in a one-nanometer lithography machine, so I wouldn't come over to help you. Come on, cheers!"

The two drank it all in one gulp and then began to taste the food on the table. While Chen Feng and Li Nian were tasting, they talked about the photolithography machine.

"Chen Feng, now that the lithography machine has been completed, what are you going to do with your mini lithography machine next? Do you want mobile phone chips, computer chips, or something else?" Li Nian asked.

A photolithography machine is a type of semiconductor process equipment, mainly used for the photolithography process in chip manufacturing. Its function is to transfer the graphics in the chip design to the surface of the silicon wafer, providing the basis for subsequent etching, ion implantation, film deposition and other processes. Lithography machines play a vital role in chip manufacturing, and their performance and accuracy directly affect the performance, power consumption and cost of the chip.

The core components of a lithography machine are the light source and optical system. The light emitted by the light source passes through the optical system, forms the required pattern, and is then projected onto the silicon wafer. The design of the optical system and the wavelength of the light source determine the resolution and exposure uniformity of the lithography machine. The higher the resolution, the finer the chip process nodes that the lithography machine can achieve, and the better the performance of the chip.

Chen Feng put down the chopsticks in his hand and thought for a moment: "I think we can start with the basics, such as making some chips for home appliances, automobiles and other fields. Although these chips have low technical content, they have a large market demand, and It is also easier to achieve mass production.”

Li Nian nodded: "This is a good idea. We can make these basic chips first, and then gradually develop into high-end fields. Although we have a one-nanometer level lithography machine in our hands, we have not mastered high-end chips. Craftsmanship."

Chen Feng took a big bite of the sauced elbow and said, "That's what I think. Although there is a one-nanometer lithography machine, we still can't make high-end chips without the process. We can only make low-end chips."

Li Nian also took a big bite of the sauced elbow, and then continued what Chen Feng said: "Actually, you can actually make high-end chips. Just hand over the lithography machine to the boss. But it depends on what you want. You should want to use it. Something else, right?”
