Hand rubbing nuclear fusion live in the wilderness

Chapter 417 Industrial Robots

The processing steps of the chip are generally only these few steps, which seem to be quite simple, but in fact they are quite complex and delicate.

Not to mention the preparation of various materials such as ultra-high-purity wafers and photoresists, it is the step of processing by photolithography machines that can be used in countless countries.

During the processing of a chip, the processing of a wafer is generally repeated many times. During this repeated processing, the positional error of the wafer cannot exceed two nanometers.

If it is a complex chip used in precision equipment such as mobile phones and computers, not only must one wafer be processed multiple times, but also multiple wafers must be overlapped.

Just like building a building, the second wafer must be perfectly covered on the first wafer, and the error between the two overlaps cannot exceed one nanometer.

What is the concept of one nanometer?
In daily life, people often use "thin as a hair" to describe slender things.

But in fact, the diameter of human hair is generally [-] to [-] microns, and a nanometer is only one-thousandth of a micron.

If a boy's hair is [-] microns, then it is divided into [-] hairs on average in the axial direction, and the thickness of each hair is about one nanometer.

With this accuracy alone, among more than 200 countries around the world, those capable of achieving accurate positioning do not exceed two palms.

After achieving accurate positioning, countries that have the ability to move precision instruments and equipment to designated locations with an error of no more than one nanometer will not exceed a palm.

Regardless of the fact that ASML is in the country of windmills and has the ability to manufacture top-level chips at the nanometer level, in fact, the country of windmills itself cannot achieve precise positioning and movement at the one-nanometer level.

ASML can do it because all the spare parts of its lithography machine come from abroad.

The top extreme ultraviolet lithography machine is the crystallization of top industrial wisdom that has assembled almost the entire human civilization.

For Huaguo, if he wants to surpass the Western countries in lithography machine chips, he is challenging the strengths of the entire Western countries with his own strength.

In the eyes of Western countries, this is an impossible thing to accomplish.

In the eyes of Chinese people, this is something that should be done as a matter of course.

In the simulated space, in the chemical laboratory, the graphene single crystal wafers that have been processed are sent into the room where the lithography machine is stored.

This room is not very big, only about [-] square meters, but there are quite a lot of equipment in it.

The carbon-based photolithography machine, ion implantation machine, wire bonding machine, wafer thinning machine, and many other equipment that have not been manufactured for a long time are all placed inside.

These equipments were imported by Korean won and are used for the processing of carbon-based chips.

In addition, there are many mechanical arms on the ceiling and walls of this room, which were deployed when the house was built.

The manufacture of a chip, whether it is carbon-based or silicon-based, requires a lot of equipment.

The lithography machine is only the most famous and important one, and other equipment is also indispensable.

For example, the unknown 'wire bonding machine', its main function is to connect the pads on the semiconductor chip and the pads on the pins with conductive metal wires (gold wires).

Then heat, pressure, and ultrasonic energy are used to tightly weld the metal leads and the substrate pads, so as to realize the electrical interconnection between the chip and the substrate and the information exchange between the chips.

The computer chip is the gold wire in the CPU, and its main source is this step.

The entire process of manufacturing carbon-based chips is controlled by Xiao Qi.

Before the carbon-based chip was manufactured, Han Yuan stayed up all night to write a new external program for Xiaoqi, just like Xiaoqi controlled the space shuttle before.

Compared with artificial intelligence, it is an undeniable fact that intelligent programs are more accurate in manipulating data.

The limit of human processing is at the micron level, but intelligent programs can easily achieve the nanometer level, as long as the measurement data is accurate enough and the precision of the equipment used is sufficient.

The advantage of automated procedures is that it can be mass-produced, and it only needs to prepare the required raw materials and write the corresponding procedures.

The places where manual assistance is required in the entire processing process will be greatly reduced. Only after the processing of each paragraph is completed, manual inspection and subsequent processing are required.

The graphene single crystal wafer that was sent into the photolithography machine started the first round of photoetching, and Won was waiting on the sidelines.

It takes ninety-nine 81 difficulties and a long time to manufacture a complete chip. It takes about three months for a chip to start from customization and transform from a wafer to a complete chip.

This does not include more time required for subsequent packaging and so on.

Of course, here, because Won is assisted by artificial intelligence programs, and he has already completed such things as circuit diagram drawing and chip design, the time can be shortened to more than half.

Nevertheless, the steps of wafer deposition, photoresist coating, exposure, computational lithography, baking and development, etching, metrology and inspection, ion implantation, and chip packaging still take about one and a half months.

Such a long time, if it is in reality, requires technicians to guard in front of the computer to prevent any problems during the processing.

However, in the simulated space, Han Yuan will not stay in this room all the time, Xiao Qi will replace him.

If there is any problem during the whole process, or after the chip processing is completed, Xiao Qi will contact him through the pager as soon as possible or in advance.

As for the one and a half months or so, Han Yuan had already figured out what to do.

After waiting for a period of time in the photolithography laboratory, after the first photoetching and developing operations of the graphene single crystal wafer were completed, Han Yuan took a slice of the processed wafer for inspection.

After confirming that the processed graphene wafer was within standard specifications, he left the lithography lab.

Most of the remaining work can be handed over to Xiaoqi.He only needs to come over to inspect and do follow-up processing after the segment processing of the chip is completed.

Leaving the lithography laboratory, Han Yuan came to the workshop.

After taking out a stack of white paper from the wooden cabinet by the wall, he sat at the table and began to reproduce the drawings in his mind.

The audience in the live broadcast room looked curiously at the lines drawn on the white paper, a little puzzled.

After all, in the eyes of most viewers, carbon-based chips are the business.

[Anchor, what are you doing here? 】

[Is the carbon-based chip ignored? 】

[The chip is still being processed, don't you need someone to watch it? 】

[Maybe there are still some drawings that have not been drawn. 】

[Hey, why do you feel that this blueprint looks a bit like a robot? 】

[It's really a little bit, does the anchor want to make a robot? 】

[It’s not bad to get a robot out, like Xiaoqi, it’s no different from a human. 】

[Robots are not so easy to make, not only the hardware requirements are extremely high, but also the software programs are also extremely demanding, the lack of one of the two is mentally handicapped. 】

[Mental retardation is a good word, just like my little love, let it turn off the light and go to sleep, it cuts off the power to the refrigerator, it's summer, and the next day the refrigerator smells bad. 】

【Little Love:? ? ? ? 】

[The current artificial intelligence is artificially retarded, and Xiaoqi, the anchor, should be the most powerful. 】

[Xiao Qi was not made by the anchor, right?The base over Mount Tai was not left by the anchor either. 】

[Yes, Xiao Qi was picked up by the anchor, I'm curious where the person who made Xiao Qi went. 】

[I really envy the anchor to have a Xiaoqi, I really want one. 】

[Want to +1! 】

[Xiao Qi can maintain a nuclear fusion reactor, and can wash and cook a robot, who doesn't want it ()]

With the drawing of Korean won, the pattern on the white paper began to take shape gradually.

A humanoid robot is quickly perfected on a blank sheet of paper.

The viewers in the live broadcast room were right, the drawings he drew were from robots.

Most of the overall process of processing carbon-based chips was taken over by Xiao Qi, and it was impossible for the Korean Won to waste this one and a half months.

So artificial intelligence robots are on the agenda.

As the audience in the live broadcast room said, no one would reject an intelligent robot butler like Xiao Qi.

The South Korean won's demand for intelligent robots is higher than that of ordinary people.

Not just for everyday life, but also for industrial needs.

With robotic assistance, there will be no shortage of labor.

Basically anything that humans can do, intelligent robots can do.

Of course, this requires an intelligent program with a very high level of intelligence.

Although it takes a lot of time to write a highly intelligent artificial intelligence, Xiaoqi can solve this problem temporarily.

In the case that the Taishan base and the Amazon rainforest base can communicate in real time through satellites, Xiao Qi can use the central computer in the Taishan base to remotely control the robots here.

This is not worth mentioning to the performance of Xiaoqi and the central computer in the Taishan base, and it doesn't even take up a small part of it.

Of course, although Xiaoqi can solve the problem of the artificial intelligence program, it can only be solved temporarily after all.

The maintenance of Taishan base is inseparable from Xiao Qi, and Han Yuan will not take him away. In the future, he will go into space, after all, he will still have to develop his own artificial intelligence program.

The artificial intelligence program cannot believe that this is the 'last words' left to him by the former host in the Taishan base.

Although this "last word" could not prevent Won from developing artificial intelligence, it always left a knot in his heart, or left a warning.

Previously, Won was thinking about writing an artificial intelligence program to control all equipment, whether it is industrial or daily life, there will be this artificial intelligence life to manage and control.

But after thinking about it later, Han Yuan decided to disassemble the artificial intelligence program.

Industry is managed by an industrial intelligence program, life is managed by a life intelligence program, and transportation and weapons are managed by another artificial intelligence program.

Several different artificial intelligence programs manage different areas, and the underlying code written by each artificial intelligence program, compilation method, etc. will be different.

In this way, even if there is a problem with one of the artificial intelligence programs, it will not affect and directly control all the equipment, leaving enough time for him to react.

Of course, this is a matter of the future, and it is the Korean won's plan for artificial intelligence in the future.

As for now, he hasn't started writing his own artificial intelligence program yet, relying on the assistant left by the previous host or the 'Little Seven'.

Although many extended function modules later were written by him, the core code is still the former host.

In the workshop, as time passed, the number of blank papers on the table gradually decreased, while the number of papers drawn with black line patterns increased.

Manually drawing various industrial equipment and machines is actually quite complicated and cumbersome.

Even putting aside the idea and setting, just drawing it will take a long time.

Because there are hundreds, thousands, or even tens of thousands of parts in an industrial equipment.

And every component is a part of this industrial equipment.

Even if it's just a bolt, it's essential.

In a modern industrial system, to manufacture a piece of equipment, all parts of the piece of equipment, including a bolt and a wire, need to be drawn on a computer or by hand.

Only after drawing all the parts and various detailed parameters can they be submitted to the machining center for manufacturing.

Even for one bolt, there may be several or more than ten kinds of bolts used in one piece of equipment.

Just like the lithography machine currently in operation, Han Yuan clearly remembers that he drew a total of 23 bolts of different sizes.

These 23 bolts of different sizes are not only different in size, but also many of them are made of different materials.

Some use medium carbon steel, some use titanium alloys, and some even use high-strength ceramics.

One can imagine how long it would take to draw all these components and label them with various parameter information.

And this step, even the Korean won is inevitable.

He needs to program every different part on the computer before it can be processed.

After all, without any data, it is impossible for a CNC lathe to give you a screw out of thin air.

That's why Han Won is so concerned about Po Jin, a metal that can sense biological brain waves.

It is too laborious and time-consuming to manually draw and write the data and graphics of various parts.

If you have an induction helmet, you can directly import all kinds of detailed data in your mind into the computer, and the speed will undoubtedly be much faster.

Not only the speed, but also the accuracy, it will be more precise.

After all, no matter how strong he is, he is also a human being. When drawing various data, he will occasionally be distracted by accidents or enter a certain data incorrectly.

But if one piece of data is wrong, the spare parts corresponding to this data will be wrong. After being manufactured, it will not be usable, and if it is used seriously, it will cause problems with the entire equipment.

So every time after plotting various data, Won will recheck it.

This process is very boring and cumbersome.

And if the data is directly derived from the knowledge information in the mind, there will be no problem.
