Chapter 190 Aoe damage, the worst country in the United States (for subscription)

(The second update is delivered, please subscribe to the monthly pass, there are still [-] words tonight, ten thousand updates today!)

After the broadcast, Han Yuan went back to the living room and got some food to reward himself, unaware that reality had gradually started to mess up.

In fact, when he used the 'electrothermal-infiltration method' to implant aluminum ions into the silicon carbide crystal material, the silicon crystal material and the chip had already begun to mess up.

A new, stable ion implantation method that can rarely damage carbon atoms in silicon carbide crystals has attracted the attention of many countries and scientists in this field.

After confirming that this method is effective, the range of AOE damage caused by this wave is not small.

Including China, the United States, the island country, the windmill country and other countries capable of manufacturing ion implanters and ion sources have begun to feel a little anxious.

Huaguo is actually fine, although there are two leading companies in the ion implanter industry in China, Kaishitong and Zhongkexin, which can be regarded as world leaders.

But the leader is the photovoltaic ion implanter, and ion penetration has not yet shown its application in photovoltaics.

What is really miserable is the United States and the island countries.

In terms of application, the ion infiltration method can theoretically replace the American IC ion implanter, although it cannot do all of them.

But the damage is really not small.

It must be known that before this method was introduced, the United States had Applied Materials that almost monopolized the IC ion implanter market.

Everything that involves chip manufacturing and high-tech alloy coatings has to be bought from him.

The bomb of 'electrothermal-ion infiltration method' dropped, at least the ion implantation of aluminum ions has nothing to do with them.

If it is really possible to apply the 'electrothermal-ion infiltration method', even if it is a part of the application.

The loss of the United States in this wave is probably a market worth billions or even billions of rice every year.

And more importantly, today's live broadcast.

The successful preparation of silicon carbide transistors has allowed scientists in this research to see the application of silicon carbide crystals on chips.

If it can be successful, it may not be a market of billions of rice gold that will be leveraged, but a market of tens of billions or hundreds of billions.

After all, silicon carbide semiconductors are much better than single crystal silicon in terms of performance.

If silicon carbide crystal material can be used instead of single crystal silicon as the substrate, the performance of the chip will definitely be improved a lot.

So after the Korean Won's live broadcast ended today, to be precise, after the detection of the amplified current of the silicon carbide transistor was successful, the countries were already in chaos.

Find people, find people, research research.

In the simulation space, after a delicious meal, Han Yuan routinely recorded today's data.

The successful appearance of the first silicon carbide transistor, although only a weak first step, greatly increased his confidence in successfully manufacturing a transistor computer.

If you compare a transistor computer to a laptop, then the transistor is equivalent to the CPU.

Its importance is irreplaceable.

Therefore, Won chose to research transistors first. With the core of computing, the manufacture of calculators can be guaranteed.

After waking up, Won went on to manufacture silicon carbide transistors and perform various tests on the transistors.

By the time all the tests such as voltage detection, Darlington tube detection, and limit parameter detection were completed, more than 20 days had passed for the secondary task.

This process was not as smooth as expected.

Although the silicon carbide crystal material is excellent, his process and equipment for manufacturing transistors are too crude.

Such links as etching and annealing cannot be perfectly controlled, which also leads to more or less defects in the manufactured silicon carbide transistors.

Even when testing the reverse breakdown voltage, I encountered the biggest problem. A hundred volts easily breaks through the collector of the first transistor, causing electrons to flow in reverse.

This problem forced Won to redesign the collector layer of the transistor.

Fortunately, he finally found a way to solve it.

The whole process took nearly a month before Won completed the detection of signal amplification transistors, not including other types of transistors.

Such as photoelectric tubes, light-emitting tubes, varactors, unijunction transistors, microwave tubes, rectifier tubes, and voltage regulator tubes have not yet been manufactured and tested.

However, compared to putting the first signal into a transistor, the subsequent manufacturing is much easier.

After all, the testing equipment and manufacturing process have been determined, and the speed will be raised several grades.

But even so, after the signal amplification transistor passed the test stably, it still took him nearly two months to manufacture the remaining transistors.

In the physics laboratory, many boxes of different sizes have been piled up.

There are different labels on it, corresponding to the different types of transistors and resistors that he has manufactured in the past three months.

There are many types, such as signal amplification transistors, and more than 1000 pieces are manufactured, while the few ones, such as voltage regulator transistors, are only dozens or hundreds.

When these transistors are completely spliced ​​together through the circuit diagram, they can become a core arithmetic unit.

For more than three months, all kinds of transistors were being manufactured, the steps were boring, far from the freshness of watching it for the first time, and the long-term audience was not even half of what it was before.

When Won announced that the transistor manufacturing was completed, the live broadcast room became lively.

【Good guy, it's finally over. 】

[The next step is to start assembling the computer, right? 】

[Three months!For three full months!Do you know how I got here? 】

[Speaking of which, why doesn't the anchor build an assembly line for transistor manufacturing?So many transistors are all handmade. 】

[Yes, it will be much faster with an assembly line, right? 】

[The assembly line is of course good, but the anchor only builds a transistor computer, there is no need to rub out the assembly line. 】

[I just want to watch the host assemble a transistor computer and see how it works! 】

【Zhenjill is patient. It took three months to make the transistors, and each one was checked by hand to see if there was any problem. 】

[This is the reason why others can do it but you can't? (dog head)]

Seeing the barrage, Han Yuan smiled and said: "Although the transistors are all prepared, it is not the time to assemble these transistors yet."

"A transistor computer, in addition to the transistor core, also needs various things such as internal memory, external memory, input/output devices, display screen, and magnetic core board."

"Although the manufacturing technology is not as high as transistors, these spare parts are equally necessary and important."

"Without one, a transistor computer cannot function properly."

"And my next goal is to manufacture the magnetic core board and memory."

"The role of the magnetic core board is to assemble these transistors and connect them in series to form computing power."

"Everyone knows the role of memory, which is to store data."
