Siheyuan: Start at level 60, beat up all the animals

He seemed to be in a dust-free workshop, with chips and circuit boards jumping on his fingertips and clicking as he assembled personal computers of different styles but equally advanced.

286,386,486, , ... a string of familiar model numbers passed by.

[Ding, congratulations to the host for obtaining the title of Senior Electronic Engineer!]

[Obtain cutting-edge electronic equipment manufacturing technology in the 21st century! Including 7-nanometer chip technology, tenth-generation LCD panel technology, solid-state drive technology, fifth-generation memory technology, artificial intelligence deep learning algorithm...]

In an instant, it was as if a door to a new world had opened, and a surging tide of information overwhelmed Li Yang.

A series of dazzling images flashed through his mind.

It was a vast wafer production line, with countless robotic arms shuttling back and forth, laser cutting, plasma etching, atomic layer deposition...

Every process is terribly precise.

On those crystal clear 12-inch silicon wafers, chips the size of a fingernail rise from the ground, and nano-scale transistors are densely packed like a sea of ​​​​smoke.

7 nanometers, 5 nanometers, 3 nanometers...Humanity's ability to control the microscopic world is leaping forward at an unprecedented speed.

This is a chip empire and the core engine that drives the future world.

In the storage field, from mechanical hard disks to solid-state drives, from DRAM to 3D NAND, from DDR2 to DDR5...

Hardware devices are constantly upgraded, the reading and writing speeds are increasing, and the capacity has jumped from MB to TB!

The progress of display technology is equally astonishing.

From CRT to LCD to OLED, displays are becoming thinner and lighter, with higher resolutions and more realistic and vivid colors.

Now, the tenth-generation LCD panel production line can even cut out more than a dozen 65-inch and 75-inch giant-screen LCD TV panels at one time!

Micro-projection technology has opened up a whole new realm for the application of displays.

Mobile phones, tablets, notebooks...they used to be big, but now they are all small and exquisite, easy to carry with you, and information is always at your fingertips.

What shocked Li Yang the most was the rapid development of artificial intelligence technology.

Deep learning algorithms, neural networks, natural language processing, machine vision... These concepts, which were only in the theoretical and experimental stages in the last century, have now become tools that can actually change human life.

AlphaGo defeated the top human chess player, driverless cars drove onto the road, and smart speakers entered ordinary people's homes...

What was once science fiction has gradually become reality.

This is a magical era and also an era of data.

Massive amounts of information converge, intersect, collide, and eventually condense into dazzling crystallization of wisdom.

What supports all of this are semiconductor chips, software programs, and the vast computing power behind them.

[System prompt: The host has mastered the cutting-edge electronic equipment manufacturing technology of the 21st century!]

Bombarded with a series of messages, Li Yang felt that he was in a state of excitement.

Every picture and every process that flashes through my mind demonstrates the amazing progress of human technology.

Semiconductors, displays, storage, artificial intelligence... these cutting-edge fields that were out of reach in the last century are now within reach of him!

As a time traveler, a "future man" living in the 60s, Li Yang is fully aware of the historical mission he shoulders.

He wants to use these advanced technologies to lead the electronic industry of Xinyan Country to leapfrog development and fill the gap in the computer field of this era!

And all of this starts with the third generation of integrated circuit computers!

After this thought, Li Yang was already eager to try it out.

In his opinion, the third-generation computers using integrated circuits are undoubtedly more revolutionary than the second-generation transistor computers that are bulky, slow, and require manual programming.

It has faster computing speed, smaller size and lower power consumption. If we can be the first to make a breakthrough in this field, it will be like being the first to get there and seize the opportunity!

Thinking of this, Li Yang picked up a pen and began to sketch quickly on the drawing.

He wrote quickly and his thoughts flowed like a spring, and soon he drew the general outline of an integrated circuit computer:

Adopt DTL integrated gate circuit, serial and parallel hybrid structure;

Magnetic cores are used for mirror storage, and magnetic tapes are used for auxiliary storage;

Input and output use telex punched paper tape + printer...

However, when Li Yang turned his attention to the supply of components, he couldn't help but frowned.

Yes, if you want to manufacture the third generation of computers, the most important thing is the integrated circuit chip!

However, with the current component production conditions, even the most basic transistors, diodes, and resistors are difficult to mass-produce, let alone integrated circuits, let alone sophisticated circuit boards.

If we rely on the existing manual assembly line, not to mention the long cycle, even if we exhaust manpower and material resources, we may not be able to produce qualified components.

However, how can the advanced photolithography machine, diffusion furnace, ion implanter, etc., which are clearly visible in Li Yang's mind, be made just like that?

They themselves embody the wisdom and sweat of several generations, and are by no means achieved overnight!

"It seems that if you want to control the life and death of chips, you have to start with the most basic equipment..."

Li Yang smiled bitterly, but his eyes became more determined.

Yes, since it is the equipment that restricts production capacity, let’s start with the equipment and create a complete set of advanced core-making tools!

Thinking of this, a grand blueprint emerged in his mind.

First, there is a photolithography machine.

It needs to have a stable robotic arm, a precise optical system, and a resolution of less than 1 micron.

With it, he can accurately transfer various complex circuit graphics onto silicon wafers.

Next, is the diffusion furnace.

It uses quartz tubes, vacuum chambers, and is equipped with an automatic temperature control system, with the maximum temperature reaching 1200 degrees Celsius.

With it, doping, diffusion, oxidation...the key processes of transistor manufacturing can be automatically controlled.

In addition, ion implanters, etchers, sputtering tables, screen printers...each one of them is indispensable.

Li Yang was thinking about it while making revisions on the drawing.

Soon, the design plan for the core-making equipment has taken shape.

Li Yang looked around, his eyes lingering on the drawings for a long time, with excitement and anticipation flashing in his eyes.

He knew that the equipment needed to manufacture third-generation computers was not ordinary precision instruments, and it would be extremely difficult to manufacture them in this era.

Li Yang picked up the blueprint and carefully examined the structure of these devices. First of all, the resolution of the photolithography machine must be less than 1 micron, which means that the stability of the robotic arm and the precision of the optical system must reach a very high level.

Next is the diffusion furnace, which requires a quartz tube and a vacuum chamber, as well as an automatic temperature control system. The maximum temperature must reach 1200 degrees Celsius, and the requirements for materials are very stringent.

Ion implantation machines, etchers, screen printers... there are so many of them, and each device is the result of a lot of hard work.

The biggest challenge in manufacturing these devices in this era is the supply of parts.

Take the robotic arm for example. Just to achieve that level of precision, there is no telling how many high-precision parts are needed.

Li Yang scratched his hair and frowned. He knew that to achieve this goal, it would be far from enough to rely solely on the existing industrial conditions.

What to do? Is it really the case that I can only make it myself, part by part?

No! Li Yang stood up suddenly from his chair. Although the existing processing methods were primitive, he could give full play to his talents as a "man of the future".

We will definitely be able to find a way! Thinking of this, he opened the drawer, took out another stack of new drawings, spread them on the table, picked up a pen and started a new round of design.

He was seen concentrating with full concentration, his pen moving rapidly across the paper as he conceived the various parts that could be manufactured under the existing conditions.

Although the designs on these drawings are inevitably crude compared to the future, they are already the most cutting-edge technology in this era.

In order to reduce the difficulty of processing as much as possible, Li Yang also deliberately changed the materials of some parts, such as using stainless steel instead of high-strength alloy, and copper tubes instead of ceramics.

At the same time, without affecting the functions, some structures have been appropriately simplified, such as reducing the number of joints of the robotic arm from 10 to 6.

After some optimization, the entire manufacturing plan finally took shape.

The next morning, Li Yang handed the drawings to the team below and asked them to immediately prepare materials and start manufacturing parts.

When everyone saw the densely packed drawings on the paper, they were all stunned. It was so precise!

Even Lao Zhang, who is usually the best at it, couldn't help but feel troubled.

But Li Yang didn't care about that. He patted Lao Zhang on the shoulder and said earnestly, "Lao Zhang, you are the technical backbone of our team. With you here, do we still have to worry about not being able to make these parts? Besides, there may be some difficulties in the early stages, but as long as you stick to it, practice makes perfect!"

In this way, under Li Yang's encouragement, everyone started to work hard.

In the workshop, machine tools roared, welding sparks flew, and everyone's face was filled with determination and concentration.

Li Yang came to the site to provide guidance from time to time, and everyone became more motivated and wanted to work all night long for several months.

However, Li Yang knew clearly that even if he worked harder, it would take him more than half a year to complete the manufacturing of all the parts with these old machine tools.

What's more, when it comes to the final assembly stage, there are still a large number of precision parts that need to be processed manually, and the workload is simply unimaginable.

After thinking it over, Li Yang suddenly had an idea. Why not take advantage of the difference in the speed of time in the small world and build a small processing plant in it?

The next day, Li Yang went to the factory to apply for a batch of CNC machine tools, under the pretext of using them to test new technologies.

When the leader heard that it was for technological innovation, he approved it without saying a word.

So, that afternoon, several large trucks transported these brand new machine tools to Li Yang's test workshop.

Taking advantage of the night, Li Yang opened the small world and began to make intensive arrangements.

I saw him move the CNC milling machine and machining center into the storage space one by one and place them on an open area.

Although these machine tools still seem a bit bulky compared to future equipment, they are highly automated and can be completely controlled by programs.

After working all night, a CNC processing workshop with complete facilities was finally built.

Li Yang had an excited smile on his face. He stretched and thought to himself, with a time flow rate ten times faster than Xiao Shi's, wouldn't it be easy to get those parts?
