Hand rubbing nuclear fusion live in the wilderness

Chapter 288 Completion of functional chip preparation

After a leisurely dinner, Han Yuan took the study medal and entered the study time after finishing the daily record.

The next morning, listening to the crisp birdsong in the forest, Han Yuan got up from the bed.

The monocrystalline silicon was smelted yesterday, and it is not difficult to separate and slice the remaining substrates.

With the help of complete industrial equipment, South Korea quickly cut the prepared single crystal silicon into the desired shape and size.

These well-cut monocrystalline silicon are called wafers.

Unlike the chips used for nanoscale lithography processing, such as the wafers used for EUV lithography machines, dozens of chips can be engraved on one wafer.

But a wafer of Korean won is a chip.

There is no way, the technical hardness is not enough, the millimeter-level engraving process, the required wafer area is naturally not much smaller.

However, compared with the magnetic crystal board of the previous transistor computer, the wafer circuit is still much smaller.

One wafer can describe circuits with one or more functions, and through these circuits, some fixed switches and programs are set to control the electric propulsion engine.

Through the combination of multiple wafer circuits, it is still possible to control the instrument and equipment without a modern computer control program.

The time when Apollo 11 landed on the moon in the United States was also in the 70s. At that time, computers were just developing.

Even the navigation computer custom-made by Rethe Orne Company is completely incomparable with modern computers.

But by carrying the AGC computer on a spacecraft with only 1MB of memory, the manned landing on the moon was finally achieved.

The computer and memory made by Korean Won are far better than the suitable AGC computer.

The computing speed is faster, and the memory is also larger.

What's more, he doesn't need to load various control systems, connection systems, etc. like modern aircraft and other vehicles.

Won only needs to control a few key things such as the start and stop, direction, and output power of the electric propulsion engine.

On the vast and boundless simulated planet, you can fly and stop at will, without worrying about colliding with other aircraft or hitting some buildings when landing.

As long as the six electric propulsion engines that provide lift don't fail at the same time, he doesn't have to worry about the aircraft falling from the sky.

As for the stability of the aircraft and the like, there is no need to worry about this.

Except when verifying that the speed can exceed [-] kilometers per hour, at other times, the flying speed is not too fast.

With the electric propulsion motors on the bottom providing lift and the electric propulsion motors on the three sides providing forward power.

This triangular aircraft can hover in the air for a long time, and with this as a basis, it is normal to fly at a speed of one to two hundred kilometers per hour, or even tens of kilometers per hour.

At this speed, it is equivalent to a car flying up.

Who is afraid of driving, and who can't drive?

At least for Won, who has five or six years of driving experience, this is not a problem at all.

What's more, after the aircraft is manufactured, various tests such as static test, fatigue test, icing test, engine extreme environment test, wind tunnel/wind control test, etc. must be carried out.

Only after all these tests are completed and it is confirmed that there is no problem with the aircraft, he will drive the aircraft into the sky.

The completion of the preparation of monocrystalline silicon has allowed South Korea to take another step forward in upgrading the computer computing core.

The rest of the work, such as photoresists, masks and other parts, may be difficult to put in human society.

But these things are the simplest for him.

For example, the mask version, Won has all kinds of mask version circuit engravings in his mind, and these circuit diagrams can form various basic control programs.

You only need to copy it and then manufacture it to use it, and there is no need to consider the completeness of functions.

Not to mention the need to consider setting up the design environment of the schematic diagram, placing components, performing preliminary schematic diagram setting and wiring, editing, modifying and adjusting, etc. like human beings designing circuit diagrams.

Won doesn’t need it, he has ready-made control circuit diagrams of various functions in his mind, and the knowledge information includes accurate information on which semiconductor components are needed at which position, as well as functions, controls, detailed instructions, and so on.

In fact, regarding the control program of the aircraft, KRW originally planned to write the control program by announcing the Chinese intelligent programming.

But it was really too late.

Up to now, less than one-third of the manufacturing of the Leluo triangular aircraft has been completed, and the time for the third-level mission has already passed 180 days.

Although in the later manufacturing, he can use technology points to exchange for various things such as electric propulsion impurity engines, lithium-sulfur batteries, and gallium-lanthanide-silicon thin-film solar films.

However, the subsequent overall assembly, various tests of the aircraft, and the final flight journey all take a lot of time.

Now his manufacturing progress has fallen behind the overall matching progress in terms of time.

The only good thing is that the technology points before the third-level mission were not used much, and they were kept. He has a lot of technology points to make up for this mission.

But if we explain the Chinese intelligent programming and use the Chinese intelligent programming to write the control program, it will consume a lot of time.

A complete language from scratch will take too much time and work to get it out, even initially.

Before Won did not finish learning Chinese smart programming, he took it for granted.

But after studying at night, he realized that he thought too much.

If he wants to learn Chinese programming, it is only preliminary. Even with modern computers, compilers, assemblers and other basic hardware, it will take more than three months.

Writing of binary code, writing of assembly language, writing of Chinese base library, writing of compiled language, writing of control program, and compiling of database.
The writing of various basic software can kill people.

Even if the Korean Won uses the one with the least functions and can only meet the basic requirements, the time required is not something he can handle in this third-level task.

Before Won wanted to release Chinese intelligent programming, he mainly wanted to do something to expand the advantages of Huaguo.

But looking at it now, the explanation of Chinese intelligent programming can only be put in the next live broadcast.

I just hope that the next task will be easier in terms of time.

But no matter what, sooner or later he will use Chinese intelligent programming knowledge information and robots to solve the problem of manpower shortage.

In fact, if the labor force is sufficient, not to mention the next task, even this task can be completed a lot of time in advance.

It can even save a lot of points.

Except for the preparation and drawing of mask plates and circuit diagrams, the remaining photoresist and other things are not difficult for South Korean won.

Although photoresist occupies a very important position in the process of preparing chips.

But in fact it is a light-sensitive mixed liquid composed of three main components: photosensitive resin, sensitizer and solvent.

But there are many kinds in terms of types.

For example, according to different exposure light sources and radiation sources, photoresist can be divided into ultraviolet photoresist, deep ultraviolet photoresist, X-ray glue, electron beam glue, ion beam glue and so on.

The most difficult thing is the extreme ultraviolet photoresist used in the EUV lithography machine, which is something that Huaguo cannot produce.

But these things are nothing to Korean won who often use chemistry to complete various material preparations and even ion infiltration implantation.

What's more, the light source he currently uses is not extreme ultraviolet light, and the requirements for photoresist are not high.

It's even easier to prepare.

The audience in the live broadcast room originally expected that Han Yuan would talk about the preparation process of photoresist, after all, Huaguo couldn't make it.

But I didn't expect that Han Yuan didn't bring an explanation at all, and just made out what he needed, which made these audiences look confused.

The drawing of the functional circuit diagram, the preparation of the mask plate, the synthesis of the photoresist, and the rest of the work can be done in a few days.

What is left for the last is the fabrication of functional chips.

This matter, Won also did not go into detail, because for a country like Huaguo, which is capable of manufacturing lithography machines, there is no need to talk about this at all.

A series of processes such as making wafers, coating films, developing, etching, ion implantation, manufacturing metal bridges, testing, etc. are not a matter at all for countries that can manufacture lithography machines.

One of the slightly troublesome things is ion implantation and chemical or physical vapor deposition on the chip to make the upper metal connection circuit.

But 'isothermal-ion infiltration' and 'chemical vapor deposition' are the two chemical methods that have been used the most in South Korea.

Therefore, the preparation process of functional chips is very simple for Won with the basic equipment and materials such as photolithography machines, monocrystalline silicon wafers, and photoresists.

The production process was so smooth that the audience in the live broadcast room didn't even have much reaction, and Won had already prepared the functional chip.

Although the prepared chip looks a bit bigger, it is a real integrated chip.

It is no different from the integrated chips prepared in the early days of human computer development.
