Please Do Not Disturb My Cultivation

Recently, Lin Wen has been researching chips.

In addition to reading a lot of materials, I also asked nearly a thousand questions to [Ask Yu Tian] and [Immortal Guidance].

——This is also Lin Wen's usual method when solving extremely difficult problems.

He split the main problem, like the root system of a big tree, and expanded it into countless small problems.

A lot of information can be obtained from the soul consumption required to solve each branch problem.

For example, as we all know, the material used to make chips is wafers.

Wafers are monocrystalline silicon after slicing, and the key processes for manufacturing wafers are polishing and layered dicing.

How to scribe without chipping, micro-cracks, delamination and other defects is an important issue.

At this time, you can use the questioning technique.

for example:

[How to use the ultrasonic assisted sawing method to cut the wafer well? 】

[How to use the laser grooving method to cut the wafer well? 】

If the consumption of the problem is astronomical, it proves that this method is wrong and cannot be achieved by human means.

If the cost of the problem is lower than the average, it proves that the method is feasible and within the scope of science.

The lower the consumption, the higher the feasibility of the method.

After comprehensive consideration, it is easy to find the correct method.

Scientific research is often a matter of direction. If you can know the correct direction in advance, it is no exaggeration to say that you can save 90% of your effort.

Lin Wen perfectly took advantage of the loopholes in the spell, only asking questions, but not spending his soul.

Just hang around outside, but don't come in.

Through this method, Lin Wen solved a lot of problems with minimal consumption.

The Changshan county chip manufacturing plant has also started preparations. Under the auspices of the recruiting king Xia Xiaoxiang, various related equipment and technical personnel are constantly being introduced.

Chang Shanjun's actions did not attract the attention of anyone in the empire.

Although it has now obtained the title of Changshan Group and is registered among major forces, the key technology of the chip has always been in the hands of the Imperial Aspen Company.

This company is jointly controlled by various major forces. Without its assistance, it is just a dream to produce the crystallization of the advanced science of the empire with just a few technicians and a few ordinary equipment?

As the company's new largest shareholder, Cheng Wei even publicly ridiculed Changshan County. He published articles in major newspapers, declaring that all the achievements of Changshan County depended on fraud, fraud and robbery.

In the article, various rumors were used to imply that Lin Wen was responsible for all the robberies in the empire.

It is implied that Lin Wen is a sex maniac with low IQ, violent and inconsistent, and contrary to human relations.

He kept questioning Lin Wen why ignorant girls were often murdered in the empire.

The implication is that Lin Wen did it.

The newspaper under him even maliciously concocted an article listing the incidence of rape cases in various regions of the empire.

He then fabricated another statistic, claiming that 80% of the girls in Changshan County had been murdered, and based on this, he ranked Changshan County at the top of the strong X list.

Cao Yuan and others who were in charge of related work in Changshan County were furious, and they fully mobilized the strength of the Changshan Association to confront them in various fields.

Cheng Qingqing from the Long Association Department specially wrote a story that Cheng Wei and the old sow had to tell.

Relying on her many years of writing skills, she has a wonderful pen, and she writes the old sow brilliantly, and writes Cheng Wei so that she wants to refuse and welcome.

There is not a word in the whole article that indicates that there is a relationship between them, but every word in the whole article indicates that there is a relationship between them.

Afterwards, Xu Ziqiang, who had the sharpest pen, questioned Cheng Wei, the elder of the empire, with pungent writing.

Why was the eighty-year-old lady brutally murdered?

Why do the sows in the imperial pig farm neigh in the middle of the night?

He didn't say a word that Cheng Wei did it, but he said every word was Cheng Wei's.

As soon as these articles came out, the comedy effect was great.

Everyone who read it burst into laughter. The governor of Zhongzhou, Wang Boan, laughed so hard that the toilet broke, and ordered the entire Zhongzhou to distribute this newspaper.

Changshan County publicly insulted the elders of the empire in the newspapers of the empire, making Cheng Wei a super laughing stock in the empire for a while.

The stories that Cheng Wei and the old sow had to tell were circulating everywhere in the streets and alleys, and there were endless jokes about him on the Internet.

This was something that was unimaginable before.

Cheng Wei was so angry that his lungs exploded.

But when he wanted to take revenge, he suddenly discovered that the imperial law no longer supported this.

He protested to the Imperial Headquarters, and the Imperial Headquarters submitted the protest to the Supreme Council.

The great elder replied with only one line: "You can clarify the truth, unless it touches on the fundamental issues of the empire, or maliciously violates the laws of the empire, otherwise the newspaper is not under the jurisdiction of the elders."

This reply made Cheng Wei's face cracked with anger.

If he categorically clarifies in the newspaper that he didn't rape the eighty-year-old lady or rape the old sow, wouldn't that be in the hands of Changshan County?

In the future, won't the name Chengwei be tied to the old sow and the eighty-year-old lady?

The yellow mud fell into the crotch, and it was either shit or shit.

Chengwei gritted his teeth, and could only swallow this breath in the end. He ignored these reports and continued to smear and ridicule Changshan County in various fields.

At the same time, he tried his best to suppress Changshan County's actions to purchase equipment and poach people in the chip industry, and prohibited any manufacturers from selling related equipment to Changshan County.

Otherwise, it would be an enemy with Chengwei and Lin Yabo Group.

The newly built chip factories and laboratories in Changshan County have also been affected to some extent.

Not only are technicians out of reach, but key equipment is also out of reach.

As for the legendary lithography machine, that is even more a dream.

Lin Wen didn't buy it at all, relying on the free prostitution of immortals and rubbing the equipment with his hands.

Even relying on his expertise, he just made a simple photolithography machine.

The principle of a lithography machine is very simple, essentially the same as that of a camera, that is, to coat a wafer with photoresist, expose it to ultraviolet light, and image it with a camera.

After the exposed photoresist is dissolved, countless complex patterns are formed, which is the structure of the chip.

Its difficulty lies in the precision of ultraviolet exposure to reach the nanometer level.

The one handmade by Lin Wen can barely reach the meter level.

There is a tinny gap.

The person in charge of the chip project is Fermi. When he heard that Lin Wen was going to develop a chip, he took the initiative to ask to participate, and even put down the superconducting project at hand for this reason.

Originally, Fermi was full of confidence and wanted to cooperate with the legendary science representative, Sheriff Lin.

In his imagination, Sheriff Lin was a perfect collaborator.

He is rich in imagination and inspiration, and every step is as untraceable as a powerful and unconstrained style.

But after the cooperation, Fermi's three views exploded.

He is indeed imaginative, full of inspiration, and every step is like a powerful and unconstrained style.

However, his every step has nothing to do with science.

Both violated the operating rules.

It even goes against common sense.

However, he can always get the right answer in weird ways.

And when Lin Wen gave him the lithography machine he was rubbing, Fermi finally couldn't help it.

"It's rubbish, Sheriff Lin, and it doesn't do anything!"

Lin Wen scratched his head: "Maybe it's useful?"

Fermi said with a rare sneer: "The chip made by this lithography machine is probably bigger than Changshan County. People can run on the chip circuit you made."

Lin Wen said with a smile: "Maybe we can also invent a computer because of this."

Fermi said angrily, "You're still joking! We're working very hard now, and you don't know how much we've been questioned outside... whoever set up a computer, I really doubt whether you understand science or not."

Fermi's assistant muttered, "I've said it long ago, Sheriff Lin is not scientific at all, and Mr. Li is a liar."

Lin Wen scratched his head: "I'm obviously very scientific..."

The assistant said loudly: "Where are you science?"

"Where am I unscientific?"

"you……"

"alright!"

Fermi didn't want to get entangled in nonsense.

"Let's find a way to do this, Sheriff Lin. To be fair, your lithography machine is good except for its lack of precision. We can find ways to improve it. But..."

He bit the root of his tongue emphatically.

"My improved chip manufacturing process cannot be verified. Aspen will not OEM for us, and may even infringe on our design drawings."

Lin Wen hesitated for a moment, but did not verify it with spells.

Chips are very complicated products, and the soul required for verification is very high.

This problem is not free, you must do it with real guns.

Recently, Lin Wen's soul has been quite nervous, and his single draw has begun to be weak, and his luck has been useless for many days.

Yuanshen can no longer be abused.

Lin Wen glanced at it, and now there are 410% of Yuanshen left, which seems to be a lot, but [asking Yu Tian] will be used up after a while.

It doesn't work without spells. If you develop chips from scratch, I'm afraid Lin Wen has already attained enlightenment and become a fairy, and Changshan County's chips haven't been made yet.

Therefore, using spells to speed up scientific research is necessary and a very scientific thing.

But how to speed up is very skillful.

Lin Wen thought for a moment, looked at the list of spells for a while, and suddenly a flash of inspiration flashed in his mind, and he said with a smile, "Don't worry, Mr. Fei, I'll make a chip for you right away."

Fermi wondered, "Are you related to Aspen Corporation or several major chip factories outside the empire?"

Lin Wen shook his head: "No."

"Then how to make it?"

"Use the lithography machine in front of you."

Fermi said angrily: "How do you make a one-meter photolithography machine?"

Lin Wen smiled and said, "I can do it manually. Give me a microscope and a nano knife, and I can manually carve a chip out."

Although Fermi and his assistant had been shocked countless times, this time, they were still shocked by Lin Wen's words.

Lin Wen didn't say much, he quickly found the nano knife in the laboratory.

This is Mr. Fei's collection.

The microscope is on the lithography machine.

The technology of the wafer has been broken through, and the laboratory can already manufacture it in small batches.

Lin Wen took a wafer casually, walked into the clean room where the lithography machine was located, and put the wafer into the reaction chamber for oxidation.

Chip engraving is carried out on the oxide layer on the surface of the wafer.

Afterwards, Lin Wen activated [Spirit of the Civet Cat] and [Eye of a Thousand Miles].

Picking up the nano-knife, Lin Wen concentrated on his expression, his hand was as steady as a rock, and gently cut the first knife on the surface of the wafer.

It feels good in the hand, a bit like cutting butter.

The process drawings are hung on the wall of the laboratory, the entire wall is there.

This is a relic of a friend of Fermi, who once participated in basic research. In the follow-up research and development, his friend passed away unfortunately, the project was forced to be interrupted, and the inheritance was handed over to him.

Fermi took it out with a little improvement.

It has 11 million transistors, and the process technology is 360 nanometers, which is barely within Lin Wen's ability.

If it is an advanced chip of 5nm or 7nm, there is nothing Lin Wen can do.

This is beyond the limits of human capabilities.

The precision of 360 nanometers is just right, which is very suitable for the performance of [Spirit of the Civet].

Lin Wen carefully controlled the nanoknife, etching out lines and patterns on the wafer bit by bit.

Although the number of 11 million transistors is large, many component structures are repeated.

After Lin Wen became proficient, his speed increased rapidly, and the first oxide layer on the wafer was etched three hours later.

Then the reaction chamber of the lithography machine started the oxidation reaction again. After another layer of conductive polysilicon was deposited on the oxide layer of the wafer, Lin Wen etched again.

The chip is not a layer, but a structure with many layers, just like the legendary Huangjiao Bay Overpass.

After each layer is etched, the lines are coated with a layer of impurity atoms that change the silicon's conductivity.

After four layers, the upper and lower contact holes are dug, and the metal alloy is installed in the holes to form the contact and interconnection structure of the integrated circuit.

Repeat the above process until all integrated circuits are complete.

Sixteen hours later, Lin Wen finally finished etching, cut the small slice from the wafer, and packaged it into the shell that had been prepared.

In this way, the first hand-made chip is completed.

Because it is fully manual operation, many harsh conditions and sophisticated instruments are not needed, and the environment does not need to be constant temperature and dust-free, because there is almost no chemical reaction except oxidation.

The entire lab-on-a-chip staff was stunned.

During these sixteen hours, all the staff, including Fermi, watched Lin Wen operate from the clean room with eyes looking up to the gods.

They don't have a microscope perspective. In their eyes, Lin Wen is almost motionless, like a statue.

They watched it like this for sixteen hours.

Only Fermi was more thoughtful and made some preparations.

Such as packaging shell.

After Lin Wen announced that the chip was manufactured, Fermi immediately took it to test.

All the staff work around this piece of a few centimeters.

If it succeeds, it would not only mean that they have also reached the 360-nanometer level of precision, but it would also mean that they have an unprecedented one-second manual chip.

Lin Wen looked at their busy faces and smiled happily. He was tired for sixteen hours and his eyes were sore.

Fermi's assistant approached him cautiously and touched his arm.

Lin Wen glanced at him: "What are you doing?"

Fermi's assistant said in a tone as if admiring a god: "Sheriff Lin, are you human? Are there any gods in this world?"

Lin Wen smiled and said, "I'm human, my name is Lin Wen, and I'm from Changshan County. There are no gods or saviors in this world."

The assistant asked in surprise, "Then how did you do it?"

Lin Wen smiled slightly.

"Although there are no gods, there are miracles and science."
