Rebirth 08: Equipment God

Chapter 399 Something Only Zhai Da Could Do

When Zhai Da returned to Shenzhou Mansion, it was already midnight.

I tiptoed and carefully opened the door, only to find that there was a light on in the master bedroom.

Zhai Da was taken aback.

Option A: Little Wood is waiting for him to go to sleep!
Option B: Little Wood just studies at his desk and waits until he goes to sleep!
Zhai Da smiled slightly, his movements became more exaggerated, and the corners of his mouth turned up.

When Zhai Daben arrived at the master bedroom door, he was about to knock when he saw Lu Wei lying on the desk, already asleep.

The lamplight, like melting honey, spilled onto her fair face. The girl lay between the open books, her legs slightly curled up, revealing a small section of her smooth back.

Looking at that quiet figure under the lamplight, Zhai Da couldn't bear to disturb him and just leaned against the door frame, lost in thought.

Until the separation of humans and birds was completed, Xiao Hei, who had crawled in from the balcony, walked pattering to Zhai Da's feet.

Then he tilted his head and admired the hostess.

Zhai Da lowered his head and whispered to Xiao Hei, "Shh~ Keep your voice down, she didn't sleep much last night, she's too tired."

Little Black pecked at the anklet: "Okay!!"

Zhai Da:
With your intelligence, you're hopeless in this lifetime.

Sure enough, the voice woke Lu Wei up. Little Wood turned his head blankly and looked around, his eyes gradually regaining their clarity.

"You're back? Are you tired?"

Regardless of whether you're tired or not, you always care more about the other person. That's probably what we call warmth.

Zhai Da stepped forward and touched his dark hair: "It's alright, you should get some rest."

Lu Wei was about to say something when she suddenly felt a sharp pain. Her slender neck felt like a rubber band had snapped, and she couldn't help but let out a soft cry of pain.

For the little wooden thing to cry out, it must be in a lot of pain.

Zhai Da guessed it was a stiff neck, so he gently massaged her shoulders and neck, and finally simply picked her up and put her on the bed.

"Lie down. A stiff neck is easy to treat at first, but the longer you wait, the harder it is to deal with. If you're unlucky, it can hurt for several days."

Lu Wei wanted to refuse, but it hurt whenever she tried, so she could only lie face down and feel the firm fingers kneading her neck.

This felt somewhat novel; it was the first time I'd ever seen him in all this time. From an angle that Zhai Da couldn't see, Xiao Mutou pursed his lips.

After a long pause, he finally asked in a breathy voice, "How did the meeting go?"

Zhai Da kept working: "It's going very smoothly. Everyone is working hard, especially the silicon carbide project team, which has made many breakthroughs in the past month. On the contrary, I, as the leader, have lagged behind a bit."

Lu Wei said softly, "It's because we've been away for too long."

His tone sounded slightly resentful.

Zhai Da laughed and said, "The power of one person is finite, but the power of many people is lasting. I'm quite happy about this. It would be so uncomfortable if everyone only worked hard when I was around."

"Won't you be disappointed? That the things you want to do are done by others? If it's mathematics, every mathematician is actually in a competition, even if they never meet."

"Not at all, because what I want to do is never the math problem itself."

As they chatted, Zhai Da inexplicably thought of the bugle call and the issue of the research institute's location.

"If you had the chance to choose any place to live, without considering any other external factors, where would you choose?"

Lu Wei thought for a moment and said, "Sky City."

I watched cartoons with my mom when I was little, and I really liked them.

"Then let's consider external issues a little. I mean, the real-world issues."

After thinking for a while, Lu Wei finally said, "The place where I am with you is the best place for me."

"However, I might hesitate a little if it comes to going abroad."

Zhai Da sarcastically asked, "Just hesitating?"

"Just a quick 'hmm,' three seconds."

Zhai Da smiled.

A pair of warm hands gently kneaded Lu Wei, without moving up and down despite the perfect angle.

Moreover, through continuous exploration, the "training master" effect of the "internal furnace" began to manifest. He had an instinctive intuition about muscles and structures, and gradually adjusted the force and angle in his hands.

About fifteen minutes later, Lu Wei's breathing became even, as if she had fallen asleep again.

The neck pain has probably completely disappeared.

In order not to wake Lu Wei, Zhai Da used his telekinesis to float up and go take a shower, and then floated back silently.

Lying in bed, I pulled the wooden arm into my arms.

As for the extra meal that was originally agreed upon today, forget it, even though he could tell that Lu Wei had already taken a bath.

This is our own timber; there's no need to exhaust its resources for personal enjoyment.

------

From the next day onwards, Zhai Da's life became fulfilling and busy again.

Based on the vague perceptions after facial recognition for each subject, Zhai Da ruthlessly categorized students into different levels, only attending a few essential courses.

The rest of the time was spent back to the rhythm before National Day, immersing myself in various laboratories.

Standing in front of the familiar CVD chemical vapor deposition equipment, Zhai Da, dressed like a rice dumpling, endured the dampness trapped inside his body as he adjusted the equipment parameters.

Beside her was Sun Ting, nicknamed "Strawberry Candy," who originally had a great figure but whose gender was indistinguishable when she wore a cleanroom suit.

"Chairman, this parameter must be set to the minimum value. There is a problem with the equipment's precision. If we raise it by one point, the doping concentration will change from N to P. Also, we need to set the thickness first and then the doping, otherwise the defect density cannot be controlled. I think there is a problem with the internal control system."

"Is this piece of junk really that troublesome?"

"I reported this to my superiors. The Japanese manufacturer charges hundreds of thousands for debugging fees, and the school stopped responding. They probably think it's still usable, but it affects the yield rate."

In just one month, the silicon carbide project team did not stagnate due to Zhai Da's absence; on the contrary, it made rapid progress.

Taking Sun Ting as an example, she has mastered the chemical vapor deposition process and summarized her own experience, achieving a yield rate of 80%, far exceeding the industry data provided by substrate supplier Infineon: 40-60%.

And the equipment used was faulty.
The others were similar. Ge Qiaoqiao had considerable experience with ion implantation and annealing, and Qi Lin had even completed the structural design of the non-semiconductor part of the motor and was making a prototype with Xu Xuejun.

Zhai Da was not impatient with Sun Ting's guidance and listened patiently.

After adjusting all the parameters in a moment, Zhai Da stood up in front of the control panel and put his hands into the black rubber gloves that were sticking out of the equipment due to the "positive pressure".

Then the "substrate," worth tens of thousands of yuan, was acid-washed and finally placed on a tray.

After that, you can just wait, unless something explodes inside and you need to stop immediately.

But Zhai Da remained standing in front of the "operation window," gazing at the limited interior space through the tinted glass.

This TEL equipment takes stinginess to the extreme. It's as if they're afraid you'll see anything inside, practically making everything a black box. You're not allowed to look, you're not allowed to repair it. You bought it for over ten million yuan, but it's as pathetic as renting.

While waiting, Sun Ting tried to observe Zhai Da's expression, but found that the cleanroom suit was useless for observation. So she carefully asked, "Chairman, at the meeting a couple of days ago, you said that everyone in the project team would receive an extra subsidy. Is that true?"

Zhai Da didn't turn his head, his eyes fixed on the tinted glass: "Yes."

Sun Ting unconsciously lifted her toes, swaying and fidgeting. If she were wearing a short skirt normally, she would probably look cute, but at this moment she just looked like a skinned bullfrog that had been slashed.

"May I ask how many there are?"

Zhai Da calmly said, "Everyone was in the learning phase before and we didn't have time to focus on this, and the members weren't finalized yet. Now we're on track. Each person will receive 1 yuan per month, and we'll also make up for the previous two months' payments."

Sun Ting paused for a moment, feeling like she was about to jump up. For a college student born in 09, this was undoubtedly at a level where she could sell herself.

Judging from the rumors circulating online, even being kept by a sugar daddy wouldn't cost that much!
With a monthly salary of 1, wouldn't she and Qi Lin together have 2? Wouldn't they be living a life of luxury?

Both she and Qi Lin came from ordinary families; the only difference was that she came from an upper-middle-class family, while Qi Lin came from a lower-middle-class family.

Before joining "π", the two of them only expected their starting salary after graduation to be 3000-5000.

However, he quickly realized that this was too arrogant, and then asked nervously, "Won't the project team feel pressured by giving so much?"

You should at least say something polite, it's to help the president out.
Zhai Da shook his head, thinking to himself that even ten thousand yuan was a burden, let alone chicken neck.

Do you know how much Cheng Mo earns annually?

"How many?"

"400."

"Take the young master!"

Sun Ting thought to herself, "Am I usually having meetings and chatting with big shots like this?"

I can't tell at all that guy who loves to show off.
Cheng Mo is absolutely worth the price. He is actually doing the work of CEO and CTO. Zhai Da can disappear for a month without any problem, but try letting Cheng Mo disappear for a month.

Lianxiang initially wanted to poach him with an annual salary of 300 million, but a few months later they offered him 500 million.

He is likely the person in the world who understands mobile operating systems the most. And he understands not only technology, but also business.

"So this is just a subsidy, not a salary. Once the project is completed and profitable, you will also have the opportunity to reach Cheng Mo's level. He went through the same process before. I have high expectations for you, and I have said this many times."

Not to mention Cheng Mo, the Hongtu project has a large number of programmers, and their monthly salaries under the new salary structure exceed 30,000 to 40,000 yuan. Zhai Da is never ambiguous about profit sharing. The idea of ​​getting rich first and then sharing the wealth together is not just the core of "Yueda Catering".

Of course, this is also related to the profitability of the Hongtu project team. Although the payment commission is not too high due to user habits, the advertising revenue is soaring. Major companies have sensed the mobile Internet era and are vying for users in the Hongtu ecosystem.

Their largest advertiser is currently Tencent, with monthly spending no less than 600 million yuan.

Moreover, both the number of users and profits are growing at a rate of over 20% per month, and it is no problem to multiply several times in a year. Therefore, the compensation offered by Zhai Da is by no means stingy.

This is what the Hongtu project team deserves.

To get back to the point, Sun Ting's surprise was simply due to her lack of experience and her naive view of society, stemming from the limited perspective of a college student.

Qi Lin, who was relatively more thoughtful, probably already had a general idea of ​​how promising the research institute's future was, so he worked even harder. Even though his role in the project team was not core, he tried his best to prove his value.

Sun Ting's thoughts wandered for a while before she snapped back to reality and reminded her:
"President, there's really no need to keep an eye on things. It'll take two hours. I've verified all the parameters repeatedly. Why don't you go outside for some fresh air? I'll stay here and keep watch."

Zhai Da shook his head: "No need for that. How about this, you go to the cafeteria and bring me back a meal. I'll eat at the entrance to save time."

Sun Ting hesitated. Logically, she should have done the hard work of guarding the equipment herself, but she couldn't resist Zhai Da's insistence and went to the changing room to change her clothes.

She guessed that the president was anxious because he hadn't come for a month and was behind schedule, which was why he was waiting so long.

It's understandable, since the president is the key figure in this project, but now he's been overtaken by these team members.

When you get lunch, please add a chicken leg for the student council president. Such a good president shouldn't go hungry.
After Sun Ting left, Zhai Da continued to focus intently on the equipment.

Gradually, the only noise in the room came from the constant operation of the equipment.

Let's first recall how a silicon carbide motor is manufactured:

1. The purchased silicon carbide substrate is grown to a suitable thickness using a weather epitaxy system, and the doping type is controlled.

2: Using a micron-level lithography machine, a preliminary functional area structure was constructed.

3: Through steps such as ion implantation and annealing, gate oxide deposition, dicing, encapsulation, and testing, silicon carbide modules are obtained.

4: Power devices are fabricated as modules, and finally a motor designed for this purpose is added.

In fact, the whole process is not difficult, especially when the participants are all geniuses in their respective fields.

It could even be said that, in just one month, their first silicon carbide motor "prototype" is almost ready.

But from beginning to end, the key point is not to manufacture "one" silicon carbide motor, but to manufacture "thousands upon thousands".

It represents improved performance and practicality, extreme cost reduction, industrialized mass production, and upstream and downstream integration in the industry.

He's not interested in scientific research and publishing papers; he's interested in developing an industry.

He never got anxious because he was slightly behind the progress of a few geniuses.

Would Emperor Wu be anxious because Huo Qubing's attacks were too fast and too fierce?

Will Pleasant Goat get angry if Boiling Goat pushes too fast?

Because he knew that there were some things only he could do.
What he wanted to do was never the math problem itself.

In the empty equipment room, Zhai Da stepped into a blind spot of the surveillance cameras, and the [Pure Gold Secret Cane] appeared in his palm.

It's a little slippery to hold through the cleanroom suit, but it's not a big problem.

He gently tapped the wall, and Bai Mo's vision quickly appeared, but unlike before, he had a new helper.

The invisible telekinetic energy transformed into tentacles, directly ignoring physical barriers, and appeared inside this TEL-made device.

They won't let us demolish it? They won't let us see it?
He could already "look around freely" before, and now he can "touch freely".

Zhai Da closed his eyes, feeling the subtle feedback from the telekinetic power. If necessary, with the help of microscopic equipment, he could even perform micron-level manipulation.

Only when we are not dependent on others for equipment and technology can we talk about mass production.

Sun Ting and her team's work involves using equipment to overcome various technical challenges under their guidance.

And Zhai Da's work.

It means: to overcome various equipment challenges.

　I need to find a way to make the update time more sustainable.

　　I don't want to keep everyone waiting so late.

　　Try your best, and if all else fails, adjust your schedule when you need to "take a long leave".
