Reborn Millennial Gamer

Chapter 841 The final battle ()

Shanghai, Zhangjiang Technology Park.

The headquarters of China Microelectronics is surrounded by dense power grids and monitors, and security forces are fully equipped.

In an inconspicuous factory, Leader Sha, Zheng Han and other leaders, led by Lu Fei, came outside the workshop.

Through the glass window, you can see a giant bus-sized lithography machine. Staff wearing dustproof suits are controlling such a huge machine. While one workbench completes scanning and exposure, another workbench is also aligning. , focus, unload and other actions.

"Because the chip manufacturing process cannot be completed with one exposure, but requires multiple exposures."

"After exposing an area, the exposure stage on which the silicon wafer is placed must move quickly, and then expose the next area that needs to be exposed. If you want to achieve nanometer-level alignment during so many rapid movements, a double worktable is necessary. It must achieve high precision and short operation time. This technology was originally only available in ASML, but now it has been broken through by us.”

Lu Fei talked endlessly and kept his treasures in mind.

The leaders said nothing and stared intently at the running lithography machine. Although it was not the first time they saw a lithography machine, they could not hold back the thought that this was the first domestic DUV immersion lithography machine. Excited, I leaned forward as much as possible, trying to get closer and see more clearly.

"It's amazing, Xiao Lu, you are amazing."

Lu Fei nodded, "Yes, 7nm is the most advanced process technology currently on the market, but according to Moore's Law, it may break through to 5nm in another year or two."

Lu Fei smiled, "On the contrary, the three node processes of 28nm, 14nm and 7nm are the mainstream in the market, especially the vast majority of our domestic chip demand, so with the domestic DUV immersion lithography machine, basically It can guarantee that we will not and are not afraid of getting stuck, and it can also guarantee that we can support it until the day we develop an EUV lithography machine."

Indeed, 28nm is the dividing line between mid- to low-end and mid-to-high-end in integrated circuit production capacity.

Leader Sha said with satisfaction: "I remember it was 7 or 8 years ago. It was also here. What you showed me was a 65nm dry lithography machine. You also assured me that we can definitely produce our own domestic immersion lithography machine." I originally thought it would take 10 years or even longer to build a lithography machine, but you gave us a big surprise! You guys built it so quickly!"

"The plan that Dr. Liang came up with, if the photolithography machine is used to its limit, through 6 masks and 9 exposures, the 5nm process can be achieved." Lu Fei answered straightforwardly.

"It's good to have an EUV lithography machine. With one exposure, one mask can achieve 7nm and 5nm. But it doesn't matter if you don't have an EUV lithography machine. You can do it with this DUV immersion lithography machine."

Lu Fei showed a humble and restrained smile.

"Definitely, but luckily it's not that bad."

Leader Sha cast an inquiring look.

In an instant, all the leaders' eyes were focused on him.

Lu Feizhi said: "AMSL and Nikon's lithography machines use Zeiss technology, but Zeiss is willing to sell to AMSL and Nikon, but it will never export it to us."

The leaders analyzed and discussed back and forth.

Lu Fei could only answer one by one, "The life span will definitely be damaged, the yield rate will definitely be lower, and the cost will naturally be higher, but there is no other way. At present, the localization of EUV lithography machines must be completely achieved. Breakthroughs, there are still many technical problems ahead, which will take time to overcome.”

Lu Fei said with a smile: "The success of the DUV immersion lithography machine is entirely due to all the employees and scientific researchers who participated in the entire project. It is their hard work and belief that led to today's lithography machine. Of course, it is also due to the It depends on the support of leaders, local policies, and the cooperation of relevant companies, colleges, and state-owned enterprises."

“What is the yield rate of producing 7nm?”

After a pause, "It can be said that this DUV immersion lithography machine embodies the wisdom and ambition of China Semiconductor practitioners. It also represents the highest level of domestic lithography machines. It is only one generation away from the international first-line EUV lithography machines." The generation is different."

Zheng Han had a proud smile on his face.

Leader Sha's eyes were filled with admiration.

Lu Fei showed a seemingly relaxed smile.

Zheng Han asked curiously.

Everyone looked at each other and smiled.

Zheng Han frowned.

Then he sighed, "There is no other way. We can only start from scratch and jointly develop it with Changchun Optoelectronics, Leica, Huawei, etc. Now we have completed the DUV immersion objective lens system. As for EUV, I'm afraid it will take a long time."

"Theoretically, this is true, but the fact is that there is already a trend of 'overperformance' in the global smartphone field. The experience of mobile phones equipped with 5nm chips may not be inferior to 3nm, which will put 3nm and below processes into an embarrassing situation, soaring The cost is only a small improvement in performance."

A leader wearing tortoiseshell glasses worried: "Will the service life of the photolithography machine be affected by such extreme use?"

"Where, where, leader."

"for example?"

“Does 5nm require EUV lithography machines?”

Lu Fei said with a smile: "Although 5nm is our current limit, theoretically speaking, TSMC, Intel, and Samsung, which have EUV lithography machines, can even hit 1nm in process technology, but the rewards will not be too high. "

Leader Sha asked: "Now Logic and Huawei's mobile phones use 7nm process technology chips, right?"

"Different chips have different yield rates, but they can basically stabilize at 70%. With gradual debugging and improvement, it can reach 80%."

"Oh?"

Lu Fei compared his pictures and said: "It is completely comparable to AMSL. It only uses 4 masks and 4 exposures to achieve the 7nm process technology."

"And yield."

"Tell me, how did it happen?"

"During this period, is it possible that the gap between Fuxin and SMIC's wafer foundry will be widened by the gap between TSMC and Intel?"

"Yes, after so many exposures, if any process fails, everything may be lost, and the cost will rise..."

"Actually, this is not the credit of Logic and China Micro. We are only responsible for the overall coordination and integrated research and development."

"The technical difficulties of the lithography machine are mainly concentrated in the light source, reflector, and workbench. Now the dual workbench has been solved, the light source problem has also been solved, and only the objective lens system is left."

Many leaders wonder, "Why do you say that? Isn't the more advanced the manufacturing process, the better?"

After all, with such a country’s important equipment coming from the Zhangjiang Technology Park, there is no doubt that Shanghai can be regarded as the “Semiconductor Capital of China.”

In addition to CPU, GPU, and AI chips that require relatively high power consumption, the rest of the industrial-grade chips use 28nm and above technologies, such as televisions, air conditioners, automobiles, high-speed rail, rockets, satellites, industrial robots, elevators, and medical equipment. , smart bracelets, drones...

But now, with 7nm, even at any cost, the limit can be pushed to 5nm, which is more than enough.

"Is there anything you need us to solve in terms of funding, policy, talent, or other aspects?"

Leader Sha has a kind face and kind eyes.

Lu Fei was not polite and immediately opened his mouth.

One dares to mention it, and the other dares to pick it up.

"I have another proposal that I hope the leaders can support."

"explain."

"That's right. Logic has been carrying out a relatively different secret project with Shuimu University in recent years, which is to study the establishment of a photolithography factory and photolithography workshop directly skipping the photolithography machine."

"Photolithography factory and photolithography workshop?!"

Leader Sha, Zheng Han and others were more or less surprised. "Yes, it takes at least a year to install and debug a DUv lithography machine." Lu Fei said seriously, "And if we directly build a lithography factory and connect the entire supply chain of lithography machines, we can get rid of the previous single If the production model of each photolithography machine is converted to assembly line production, and mass production of photolithography machines of various precisions can be achieved according to different precision requirements, the price of photolithography machines and even chips can be driven down. What do you think?"

"Hi~"

The leaders in the on-site technical field immediately started whispering.

"There are many roads, there are many choices. Try it boldly and go for it. We will always be your solid backing."

Leader Sha patted Lu Fei on the shoulder.

"Yes, leader!"

There was a hint of excitement in Lu Fei's tone.

"Science and Technology Daily recently summarized 35 bottleneck technologies that restrict our manufacturing industry. Have you seen it?" Leader Sha walked outside the factory.

"Look." Lu Fei immediately followed.

"What do you think?" Leader Sha asked.

"It looks like there are 35 items, but the actual situation is not right. Many items have been overcome by logic, such as aviation design software, EDA design software, tactile sensors..."

Lu Fei said truthfully: "Some are being conquered, such as lidar. We are tailoring commercial-grade lidar for future intelligent driving systems."

"I know that you and Logic have done a lot overtly and covertly over the years, but these are not the key." Leader Sha said seriously, "The chip is the top priority. After all, fields such as electric vehicles and artificial intelligence are inseparable. Open the chip."

"If it really gets stuck, it may be the dark side of China's semiconductor industry for the time being, but in the long run, isn't it an opportunity for the rise of our domestic semiconductors?"

Lu Fei disagreed.

It wants to completely block the development of China's chips, but it gives domestic products an opportunity. When "domestic substitution" becomes a trend, China Semiconductor will explode with huge potential.

After many years of logical layout, we can usher in the real trend!

From the light source system to the objective lens system, from the immersion system to dual workbench R&D, from photoresist to photomask, from photolithography machine defect detection equipment to glue coating and development equipment, whether it is core components or supporting facilities, all are domestically produced. Will take off slowly.

"well said."

Leader Sha smiled and said: "By the way, you just said that it will take one year to install and debug the lithography machine. If you add in the manufacturing, wouldn't it mean that it will take more than a year before a lithography machine is actually put into production?"

Lu Fei nodded, "Yes, so we are working overtime now to make as many units as possible before taking action against Logic and Huawei."

Zheng Han asked: "If Logic and Huawei are now in a situation where ZTE cuts off supply, what will you do?"

"Even if Qualcomm and other suppliers don't sell chips to us, we are not afraid. Logic has long predicted that such a day will come, and we have made backup plans in advance."

"Backup plan?"

…………

San Francisco, golden mansion.

"Mom, why hasn't Dad come to see us for so long?" The mixed-race Lu Yang lay on the bed and blinked.

"He'll be coming to see us soon."

Ivanka closed the curtains, walked to the edge of the bed and sat down, held her son's forehead and kissed him, "Go to sleep."

"Good night, Mom."

"Good night."

Seeing him close his eyes, Ivanka turned off the bedside lamp and quietly exited the bedroom, her smile immediately disappearing.

At this moment, a text message was received on the phone.

All of a sudden, I went straight to the study room. The decoration inside had not changed. It still maintained Lu Fei’s original design. When I came to the computer, I saw that the Washington Post, the New York Times and many other media had reported on Logic and Huawei. Sanctions——

Logic and Huawei are officially added to the list!

American suppliers collectively cut off supply!

"finally come!"

Ivanka was very excited, although she knew that Lu Fei would never beg for mercy easily, nor would he be as easy to deal with as Zhongxing, but so what? It’s just that the resistance lasts longer!

Sooner or later, we have to be like ZTE and come to the United States obediently.

With this thought, she opened the bottom drawer. There was a key hidden in the secret compartment. She glanced at the small, inconspicuous room in the corner, pushed the door open, and turned on the lights. Ambiguous pinks and enchanting purples intertwined. Together, we light up the surroundings.

There were tons of toys and cosplay costumes hanging on the walls, and damn memories came flooding back immediately.

Ivanka thought of everything here again, took out a loose whip and waved it twice in the air.

Suddenly, a sound broke through the air!

Immediately afterwards, the whip fell on the puppet tied to the cross, and a portrait photo of "Lu Fei" was pasted on its face.

"Clap clap clap!"

"Why not come to America!"

"Am I, the first daughter, at a disadvantage if I marry you, the richest man in the world? The combination of the two of us is obviously beneficial to both of us, and we even hope to become a member of old money!"

"Lu, you bastard!"

"Why did you only leave so little real estate for me and my children in America, and why were you reluctant to give me even the shares of the Warriors?!"

Like a resentful woman, Ivanka kept waving her whip wildly, as if the "Lu Fei" puppet in front of her was alive, venting her dissatisfaction, especially when she thought of Lu Fei's holdings of Netflix, Apple, Amazon, Silla and other US stocks did not have her share.

And it’s not her child’s share!

But she obviously completely forgot about the media group Lu Fei left to her, which included TV stations, newspapers, movies, streaming media, comics, theme parks and resorts, and peripheral derivatives...

Not to mention, shares in Facebook, Twitter, and SpaceX.

"Waiting for you to come to America, I'll have something beautiful for you!"

"Whatever you did to me here before, I will do to you!" Ivanka panted, her face covered in sweat.

After enjoying themselves, the dark room was closed again.

"Whoo~"

Ivanka put the key back into the secret compartment and was about to turn off the computer when she saw the word "logic" trending on Twitter.

It is a logical official announcement, the backup plan is launched!

All "spare tires" became "regular" overnight!
