Rebirth 08: Equipment God

Chapter 374 Buy only cheap, not right.
After communicating with the "π" members once, Zhai Da quickly began the preliminary work for the project.

The first step is to order the equipment.

The cheap ones say "Who can stop me!", the expensive ones say "My alma mater, save me!"

Silicon carbide semiconductors are a very cutting-edge field. In a more abstract way, it involves using chemical vapor deposition to build a silicon carbide film (epitaxy) of a designed shape on a substrate, and then using photolithography to build the "structure" to achieve the purpose of manufacturing functional devices.

Most people would probably be startled when they see the words "lithography machine," feeling that it suddenly becomes a high-end and difficult machine.

Especially the time before Zhai Da's rebirth, it's no exaggeration to say that everyone turns pale at the mention of it.

But don't panic, they are completely different fields.

CPU and GPU chips are "logic chips," which prioritize integration density and precision.

Silicon carbide semiconductors, on the other hand, prioritize durability.

Its creation and widespread application are due to its resistance to high voltage, high temperature, and high frequency, which is completely different from the concept of silicon-based logic chips.

Even for sufficient durability, there are requirements regarding thickness.

Even if it still requires a lithography machine, guess how many nanometers its precision is?
Sorry, it's "micron-scale", generally between 1 and 5 microns.

This is equivalent to 5000 nanometers or 0.5 filaments.

A neck trap? My neck's in the atmosphere! You can't get stuck anywhere!
If it were any taller, Zhai Da could rub it by hand.
Therefore, the lithography machine is completely unnecessary to focus on throughout the entire process.
Of course, this does not mean that the corresponding equipment is cheap. For example, chemical vapor deposition equipment and substrate laser lift-off equipment each cost more than 1000 million yuan and have extremely high maintenance costs, but Harbin Institute of Technology has all of these.

Because the biggest application of silicon carbide semiconductors is currently in aerospace, which is its original field.

In 09, with several geniuses and the backing of Harbin Institute of Technology with complete equipment, it was a perfect combination of timing, location, and people.

In short, after discussing the general outline with everyone, Zhai Da drew up a procurement list for equipment, which consisted of small, inexpensive, frequently used, and low-environmental-requirements items that would be placed in the research institute.

The total price is approximately 700 million.

Others will take advantage of the principal's promise to make things convenient, while also observing as they go, and may need to make additions as needed.

Currently, the Hongtu OS project has begun to generate output, paying out tens of thousands of yuan in commissions daily, and also receiving a significant amount of advertising revenue. Although it is far from reaching its peak due to the limited number of devices, it has indeed achieved self-sufficiency.

After all, their team is not very large.

Therefore, the research institute no longer needs Zhai Da to inject capital into it as a sole proprietor. On the contrary, the 2000 million yuan that was previously invested still has a considerable amount left, which is enough.

Sigrún has taught at the Iceland University of the Arts as a part-time lecturer since and was Dean of the Department of Fine Art from -. In – she held a research position at Reykjavík Art Museum focusing on the role of women in Icelandic art. She studied fine art at the Icelandic College of Arts and Crafts and at Pratt Institute, New York, and holds BA and MA degrees in art history and philosophy from the University of Iceland. Sigrún lives and works in Iceland.

In the following days, the team consisting of Zhai Da, Ge Qiaoqiao, Sun Ting, and Qi Lin worked together at the Mechanical Core Research Institute to plan the project.

There should be a general outline from theory, design, experimentation, to verification.

It has been proven that it is extremely difficult to suddenly involve college students in specific work.

But the facts also proved that their growth rate was indeed extraordinary.

In particular, Zhai Da can provide them with a clear and specific path.

Almost every day, he could sense the changes in the three of them, and he could often get useful inspiration from their minds.

Zhai Da even gave them a cheat code!

I deliberately used a Polaroid camera to apply the effect of an "inner rave light" to the light bulb in the meeting room I frequent, and then added the blessing of "execution of Old Yu".

This brainstorming session lasted for three days, and even SpongeBob's head was itchy when he arrived.

As the route and plan became clearer, the division of labor gradually emerged. Sun Ting had to start preparing for chemical deposition and photolithography, including mastering the use of all the equipment and being able to take initiative in leading the corresponding tasks.

Ge Qiaoqiao's work involves ion implantation and annealing processes, magnetron sputtering, and miscellaneous tasks.

Qi Lin is responsible for the structural design of components and motors.

As the project's head coach, Zhai Da is involved in almost every aspect.

Besides his expertise in mechanical/structural design and his exceptional manual dexterity to bridge the gaps in the "first-generation machine," he could delegate all processes to others, but he himself had to understand them as well.

The moment to test what he has learned over the past two years has arrived.

Time marched on, and everything seemed to be going smoothly. However, the start of the school year would eventually arrive, inevitably disrupting this efficient preparation process for a short period.

On August 31, the summer vacation for this semester officially ended, and students from all over the country returned to the campus.

If there's anything different from before, it's that everyone is discussing "Hongtu OS" and "Zhai Da".

Zhai Da was already quite famous when he first entered the school, but he always seems to be able to refresh everyone's perception every now and then. From the top scorer in the college entrance examination to the "three-time champion" who swept the awards, he has now become a "new tech darling".

This is a reputation that has spread globally, and many overseas media outlets have reported on it, because Zhai Da's age is indeed a topic of discussion.

There were also lucky ones who managed to snag a "Meizu P9". Students from Harbin Institute of Technology (HIT) generally paid more attention to it. At least 80% of HIT students watched that launch event that went down in business history, and even if it wasn't broadcast live, they caught up on the relevant content afterward.

Of course, besides the amazement at Zhai Da personally, the reputation of Harbin Institute of Technology's "joint research and development," and the fact that another key member, Cheng Mo, is also a student of Harbin Institute of Technology, all contributed to an increased level of admiration for their alma mater. "Harbin Institute of Technology is awesome now~ When I applied to Harbin Institute of Technology back then, my classmates laughed at me, saying that my score was high enough to get into Nanjing University. This summer, my high school classmates were all talking about our school at our reunion."

"Speaking of which, bro, why did you choose Harbin Institute of Technology in the first place?"

"Because of my first love, I went to Harbin Normal University"

"Huh? You have a girlfriend? How come I didn't know?"

"No, they dumped me in freshman year and went to find a senior."

As they were talking, the two senior students spotted the familiar black luxury car on campus. As time went on, everyone learned that the car was called a "Panamera".

At first, everyone thought this car was a bit too arrogant, but looking back now...
Zhai Da is too low-key. With his status, he should be flying a helicopter!

He even comes to school every day! He is truly a model of respect, frugality, gentleness, kindness, and humility! A role model for us all!
"It seems like they recruited another top scorer this year, things are really getting better."

"It's a good thing that our alma mater has returned to its former glory, and our degrees will be more valuable in the future."

"By the way, where are you planning to go after graduation?"

"Need I say more? Let's see if the Mechanical Core Research Institute will take me."

Zhai Da, inside the car, was unaware of the discussions outside, but he had a general idea of ​​what was going on.

Because more and more people are asking him for autographs.

This is only natural. Every time something happens, people will remember that there is a celebrity around. After a while, when things quiet down, fewer people will be there, and the cycle repeats itself.

After parking his car at the student activity center, Zhai Da came to pick up his personal class schedule. His third semester was still packed with 22 courses, which meant he would have enough credits by the end of the semester.

I knocked on the office door, and the exclusive school guide tool "Jiang Xiaobai" was already waiting.

"Zhai, are you here to pick up your class schedule? I've also prepared Lu Wei's; they're all here."

Zhai Da took a look and saw that it was still densely packed with text, but as long as he could get through the first week, the subsequent "no listening required" would relieve most of the pressure.

Oh, and there's my graduation project.
He has already obtained the right to choose his own topic, as has Xiao Mutou. Zhai Da has basically decided to use a part of "silicon carbide semiconductors" as the content of his graduation project, so that he can do both without delay.

It's absolutely a drop in quality among undergraduate graduation projects.

As for Lu Wei, she could have simply used "Sensitivity Conjecture" as her graduation thesis, but Xiao Mutou might have some new ideas.

Zhai Da put away the timetable, but did not leave. Instead, he took out a black box from his bag and placed it in front of Jiang Xiaobai.

"This is?"

Zhai Da smiled and said, "A Teacher's Day gift."

A Meizu P9 phone.

Jiang Xiaobai was stunned for a moment, then quickly waved his hands haphazardly to refuse, "No, no, no, this is too precious! I can't accept it!"

As her personal mentor, she naturally paid more attention to Zhai Da in private, attending all of his works, watching his press conferences live, and occasionally engaging in online debates with him.

Of course, they were too embarrassed to show any of this, since they were teacher and student.

No messing around.

She had checked this phone before. It was 3688, and it was out of stock and had a premium price. You might not be able to buy it even for 5000!

Zhai Da pretended not to see Jiang Xiaobai's old feature phone and smiled, saying, "Don't be in such a hurry to refuse. You've helped me and Lu Wei a lot since we entered the school, so you deserve this."

"That won't do... As an educator, I absolutely cannot make such a fundamental mistake! What's the difference between this and accepting bribes? What teacher would do that?"

“I also gave it to the principal, and he accepted it.”

Jiang Xiaobai:
Gently stroking his own Will of D, Jiang Xiaobai swayed towards the direction of the principal's office: "I'm sorry, Principal, I didn't mean to."
In the end, he accepted it, not for himself, but for the sake of the principal's innocence.

Zhai Da smiled and said, "By the way, I'll be quite busy this semester, so I hope to apply for more exemptions from certain courses, such as these."

Zhai Da marked up the timetable, cutting more than half of it, which was even more outrageous than in previous years.

However, people are always moving forward, and so is the school's perspective.

In previous semesters, the school still viewed it as a "test," but as Zhai Da consistently and perfectly handled his heavy coursework, maintained a 4.0 GPA without ever faltering, and achieved more and more success in the community, the test turned into "support."

Jiang Xiaobai glanced at it and felt that the pressure wasn't too great; it was just a matter of making a few more trips to the teacher.

"I understand. I'll get it done for you tomorrow. Are you planning to focus on Hongtu OS this semester, Zhai?"

Zhai Da shook his head: "No, I started a new project, in the semiconductor field."

Jiang Xiaobai:
It's getting more and more abstract.

Is the capable all-powerful?
