Chapter 319 Chapter 335: Reduce chip manufacturing costs by 70%

Compared with EUV, NIL nanoimprint equipment can reduce energy consumption by 90%.

At the same time, due to the better conversion rate and lower R&D costs, which are about 60% lower than EUV R&D costs, nanoimprinting is also regarded as the most likely mainstream lithography technology to replace EUV to achieve processes below 7 nanometers.

Since nanoimprint technology has so many advantages, why has it been developed for 1995 years since it was proposed in 20, but it has not achieved real large-scale application?

There are three main difficulties that need to be solved.

First of all, the first difficulty is the problem of template production. If you want to obtain EUV lithography-level processing accuracy, the size of the template itself must be made very small. The preparation of the template requires extremely high processing technology, and it is necessary to ensure a very perfect flatness. and error.

At the same time, nanoimprint technology is also extremely demanding in the material selection of the template.

Not only does it need to have high strength, mechanical strength and corrosion resistance, but it also needs to ensure a very small expansion coefficient at high temperatures to meet repeated printing requirements.

According to different process requirements, there are currently silicon templates, quartz templates, nickel templates and polymers, PDMS, composite templates, and so on.

The second key technical difficulty is in the imprinting adhesive. Unlike traditional photoresists, the imprinting adhesive required by NIL needs to have good adhesion to the substrate and low viscosity to successfully complete the entire degumming process.

At the same time, it needs the characteristics of small shrinkage and strong coating.

After 20 years of exploration, nanoimprint adhesive is still in the stage of continuous exploration and optimization.

The last difficulty is in terms of imprint and etch equipment.

We can see that the nanoimprint method and the traditional lithography method have taken a completely different path.

Ideally, the entire imprint and etch process should be free from any bubbles, deformation, and sticking.

There are very high requirements for the stability of the uniformity of the glue coating equipment.

Even very slight vibrations and mechanical errors can cause a significant drop in yield.

Especially in the production of logic chips with complex structures, it is impossible to overcome the problem of processing deviation in the short term.

If you want to have a complete set of NIL nanoimprint technology, you must purchase the corresponding supporting technology.

In addition to NIL nanoimprinting equipment, it is also necessary to purchase imprinting glue technology and etching equipment.

The prestige value required for NIL nanoimprinting equipment is not high, and it only needs one billion prestige points to take it down, but its research costs and development time are terrible.

It takes three years of research and development time and 50 billion research and development costs.

Because NIL nanoimprinting and EUV lithography technology are different, EUV lithography technology already has a complete production chain, and most NIL nanoimprinting technologies can only be developed by ourselves.

This is also the reason for the long and high cost of the technology development cycle.

As for imprinting glue technology and etching equipment, it is much simpler.

Imprinting glue only requires 5000 million reputation points, [-] million R&D expenses and a six-month R&D cycle.

The research and development cost of etching equipment is the cheapest, only needing 3000 million reputation points, [-] million research and development expenses, and a six-month development cycle.

In other words, if Cao Mang wants to fully realize this technology, he needs 22 billion reputation points and 6000 billion 50 million research and development expenses.

The most impressive thing about this technology is its energy efficiency.

Most of the cost of manufacturing a chip is spent on electricity.

NIL nanoimprinting appears to reduce manufacturing costs by more than 70%.

That is to say, the cost of a 300-yuan chip can be reduced to 90 yuan through this technology, and the cost gap is all profit.

Although Cao Mang has purchased 7-nanometer EUV laser manufacturing technology.

However, Cao Mang doesn't mind making NIL nano-imprinting, after all, this thing can reduce the manufacturing cost by 70%.

In a blink of an eye, Cao Mang came to Wang Xiaoyuan's villa.

After Shen Lidong and others sent Cao Mang to the villa, they lived in the villa next door.

In order to arrange the residences of these bodyguards, Cao Mang asked Wang Xiaoyuan to buy two more villas. Driven by Cao Mang's financial ability, the original owners moved out on the same day.

When Cao Mang returned home, he saw sisters Liu Qianqian and Leng Xiaoxiao playing video games in the living room.

Wang Xiaoyuan and Yin Suwan were cooking dinner in the kitchen.

As for Lu Chuxue.

Lu Chuxue had been free since she sold the Deep Blue Optical Factory, so she asked Cao Mang if there was any work he could do for her.

Cao Mang left the matter of investing in Huawei Cloud to her, and Lu Chuxue followed the financial team to Guizhou to conduct the financial review of Huawei Cloud.

Although Cao Mang believes that the old man will not cheat him on this matter.

But what needs to be done still needs to be done.

"Sister Qianqian, come here and save me." Leng Xiaoxiao said excitedly.

The whole person moved together with the characters in the game.

"Xiaoxiao, there are a lot of zombies over there, I can't rush through." Liu Qianqian replied.

Cao Mang is also very helpless for these three Internet addicted girls.

It is the most gratifying thing for Cao Mang that they can live in harmony.

"Ouba, you're back." Yin Suwan shouted excitedly when she saw Cao Mang when she came out of the kitchen serving dishes.

Yin Suwan trotted to Cao Mang and gave him a hug.

"Thank you." Cao Mang pinched her nose and smiled.

Several people heard Yin Suwan's voice and noticed that Cao Mang was back.

The two sisters Leng Xiaoxiao and Liu Qianqian turned their heads to look behind them.

"Oh, little brother, why didn't you call us when you came back?" Leng Xiaoxiao shouted happily.

"Thank you." Leng Xiaoxiao greeted briefly.

Leng Xiaoxiao's personality is different from that of her sister. She is taciturn, but in bed.
At some point she is passionate, she just doesn't know how to express it.

"You're back." Liu Qianqian smiled.

"Miss me?" Cao Mang walked to the sofa and sat down, putting his arms around Liu Qianqian's waist and asked.

"I didn't expect that our sisters would be living well without you." Liu Qianqian rolled her eyes and said arrogantly.

After getting along for a period of time, Liu Qianqian got along very well with the girls.

Although we have never carried a gun together, we are already good sisters.

If Liu Qianqian was not pregnant, Cao Mang would definitely teach her a lesson and let her know who is the head of the family.

"Xiao Xiao, come here and help serve the dishes, you can eat right away, sister Qianqian, you can wash your hands and eat." Wang Xiaoyuan called.

Because Liu Yifei is two to three years older than them, the women in the family are all called sister Liu Qianqian.

Moreover.

Now that Liu Qianqian is pregnant, her identity as the empress of the palace cannot escape.

It's not too much for them to call sister Liu Qianqian.

"Thank you, Xiaoyuan." Liu Qianqian smiled.

"It's not hard." Wang Xiaoyuan replied with a smile.

Cooking is one of her hobbies, and she does all the cooking at home.
