Hand rubbing nuclear fusion live in the wilderness

Chapter 189 The first silicon carbide transistor (for subscription)
(It’s going to be updated today, please subscribe for support, Chapter 1 will be delivered with [-] words, and there will be more in the afternoon, please ask for a monthly ticket)
Picking up the cooled and solidified silicon crystal, Han Yuan first checked the state of the silicon crystal, and after confirming that there was no problem, he showed it under the camera and said:
"The one in my hand is a high-purity silicon crystal. Although it hasn't been tested and I don't know how pure it can be, but the reduction method of trichlorosilane can increase the degree of silicon to more than 90.00%. "

"Silicon crystals of this purity level can be used to make P-type silicon."

Put the prepared silicon crystal back into the container for melting, add boron crystal powder, then stir evenly, and continue heating.

Control the heating time, let the boron crystal powder create a sufficient number of holes in the silicon crystal, and then plate it on the silicon carbide crystal to form a polysilicon film.

This is extremely P.

After processing the P pole, first trim the shape and size, and then pull the aluminum into an aluminum wire with a stretching machine, corresponding to the third stage connected to the transistor, and fix it with molten silicon dioxide as a contact.

The processed silicon carbide crystal is polished by the machine tool, and the excess peripheral part is cut off at the same time, and then the plastic is melted to wrap the processed silicon carbide crystal in a layer. After forming, it is a complete signal amplification crystal.

Melting silicon, making P, coating, polishing, and polyplasticizing, these processes are simple and easy to understand, and even most of the viewers in the live broadcast room can understand them, but there are many steps and it takes a long time.

It wasn't until four o'clock in the afternoon, after nearly ten hours of busy work, that Won manufactured the first silicon carbide transistor.

The small transistor is neither big nor small. It is flat and has three legs. As he expected, it is about the size of a thumbnail, less than one square centimeter.

Holding this small transistor in his hand, Han Yuan raised his heart, and said with a trace of nervousness:

"Now that the SiC transistor has been manufactured, the next step I will do is the most important step, which is 'testing'."

"This transistor is a signal amplification transistor. If it can amplify electrical signals normally, then this means that my transistor computer may be able to be manufactured."

"Whether you successfully enter the information age or fail depends on the next test!"

Hearing this, the audience in the live broadcast room also felt a little nervous and excited.

【Awesome! 】

【Chong rush! 】

[Come on, anchor!Must pass. 】

[Hand rubbing the transistor, it's incredible, it exploded. 】

[Is the transistor in the CPU? 】

[The greatest invention in human history - the transistor! 】

[This live broadcast reminds me of the transistor that has never been invented in the radiation world view, which makes that world go on a completely different path]

[I don’t think it’s the greatest invention, but electricity is the greatest invention, right? 】

【I think it's fire. Without fire, human beings can't eat cooked food, can't develop their brains, and there's no way to talk about it later. 】

【The Invention That Changed the World - Electricity By Nikola Tesla! 】

[Passing by studying semiconductors~ This is too hardcore! 】

With the first signal amplifier transistor prepared, Han Yuan went straight to the physics laboratory next to the chemistry laboratory.

The physics lab is built at the end of the first level mission, next to the chemistry lab.

Stored in it are all kinds of industrial electrical appliances manufactured by him in the first-level mission.

There are fuse switches, switching appliances, voltmeters, ammeters, test meters and other industrial and experimental appliances, including backup generators and motors.

Because there are not many places where electrical appliances are used in chemical experiments, and the physical laboratory is very close to the chemical laboratory.

It's only two steps away, so Won didn't move some of the voltage and current test meters inside.

Come to the physics laboratory and assemble the test equipment first.

Electric clamps with copper wires, current testers, voltage testers, resistors of different resistances, wires, relay boards, sulfuric acid batteries and other electrical appliances.

These things are connected in series with each other to form a set of components that can test the magnitude of current and voltage.

Its function is similar to a modern electric current multimeter.

The direct current is output through the sulfuric acid battery, and then the voltage is reduced through resistors of different resistance values.

Every time a resistor passes through, there will be a current and voltage test meter to show the current and voltage after transformation.

Finally, after several times of voltage transformation, the current meeting the test requirements is reached.

Since this is the first test, Won is worried that the silicon carbide transistor will be burned if the current is too high, so he set up a few more resistors and adjusted the output current to 3V and 100 microamps.

This value of current will basically not cause too many problems when passing through most transistors.

After the current is connected in series and the output current and voltage of the component are adjusted, South Korea connects the P and N poles of the three poles of the silicon carbide transistor into the component.

For the rest, as long as he connects the power supply of the sulfuric acid battery.

This time, the audience in the live broadcast room knew that the critical moment was coming without the reminder of the won, and the barrage on the virtual screen was much less.

Everyone is waiting for the connection of the power supply, waiting for the arrival of the last moment.

The scientific research scholars from all over the world squatting in the live broadcast room stared at the live broadcast without even blinking their eyes.

Because of the special method used by South Korea to implant aluminum ions into silicon carbide crystals, it attracted their attention.

All scientists working in this area wonder whether doping the implanted N-drift layer in this way will work.

Taking a few deep breaths of the cold air from the air conditioner, he calmed down his heartbeat, gritted his teeth, and clamped the electric clip in his hand to the electrode of the sulfuric acid battery.

Whether it is success or failure, there is no escape.

After the power was connected, Han Yuan immediately shifted his gaze to the current test meter, and the shooting equipment beside him also captured the ammeter into the live broadcast simultaneously.

With the beating of the pointer of the current test meter, after just two seconds of silence, the barrage on the virtual screen suddenly increased.

【Moved!Moved! 】

[The pointer moved! 】

【Did you make it? 】

[Awesome!Anchor Sai Gao! 】

【Is this successful?Anchor?The meter pointer moved! 】

[The movement of the meter pointer only means that the transistor can conduct electricity. As for whether the amplified current can be successfully controlled, this needs to be judged specifically. 】

After the sulfuric acid battery was connected to the power supply, Han Yuan stared at the two current test meters without blinking.

When he saw the pointers of the two current test meters beating at the same time, and the reading on the first current test meter was obviously different from that of the second meter, his heart beat violently, and the stiff expression on his face was relieved Come down, showing a bright smile.

He succeeded!

The first silicon carbide signal amplifier transistor prepared was successful!
Can't wait, Han Yuan opened his mouth to share this joyful mood with the audience in the live broadcast room.

"friends!"

"I succeeded!"

"This silicon carbide signal amplification transistor has successfully worked!"

"The reading on the first ammeter is [-] microamperes, and the reading on the second ammeter is [-] milliamperes."

"These two sets of numbers mean that the input current forms a collector current from the collector area after passing through the silicon carbide transistor."

"One hundred microamps to [-] milliamperes, that is to say, the current effect is amplified by nearly two hundred times."

"This number is enough to prove that the silicon carbide transistor I made was successful!"

Hearing this, the audience in the live broadcast room also sent barrages to express their congratulations and praise.

【Awesome, my brother! 】

[Magnify two hundred times!Awesome! 】

[This is really awesome. One person starts from scratch and rubs transistors with his hands. Will he rub chips in the future? 】

[It will definitely be. In the morning, the anchor also said that monocrystalline silicon will be manufactured. If you don’t rub chips, what are you doing with monocrystalline silicon? 】

[Ma Dan, does this anchor have a system? 】

[If it's not aliens, or there is a system, one person rubs the chip by hand, this is definitely not something that people on earth can do. 】

[I also seem to want a system! ! ! 】

[It is enough for me to be born again, I have memorized dozens of lottery tickets and the World Cup (dog head)]

[Good guy, the upstairs is prepared. 】

[Input a current of [-] microamps, can it output a current of nearly [-] milliamperes?Why is this technology not used to generate electricity? 】

[? ? ? ? ?Does this start to violate the conservation of energy again? 】

[My high school teacher said that anyone who wants to say that a perpetual motion machine can be manufactured can directly slap his big ears. 】

[Upstairs is a punishment. 】

Looking at Zhenghuan's barrage during the discussion, Han Yuan smiled and said, "From inputting [-] microamperes to outputting [-] milliamperes, this does not mean that energy is not conserved."

"The principle of a transistor amplifying current is that the emitter region emits electrons to the base region after electrification. After the electrons enter the base region, they are first densely concentrated near the emitter junction, and gradually form a difference in electron concentration."

"Under the action of the concentration difference, the electron flow is promoted to diffuse in the base region to the collector junction, and is pulled into the collector region by the electric field of the collector junction to form a collector current."

"Thus giving the transistor a current-amplifying effect."

"It's like adding up and adding up."

"Now that the two current test tables have successfully verified that the transistor I manufactured has an amplification effect, the next step is to test its stability."

As he said that, Han Yuan disassembled the silicon carbide transistor, and then began to adjust the input current again and again, incorporating it into the transistor for testing.

For each test, he will use paper and pen to record the intensity of the input current and current collection.

"The first time: input 100 microamps, collect 19.7 milliamperes, and expand the current by 197 times."

"Second time: Input 125 microamps, collect 24.4 milliamperes, and expand the current by 195 times.
"The third time: input 75 microamps, collect 14.7 milliamperes, and expand the current by 197 times."

"The fourth time: Input 300 microamps, collect 59.6 milliamperes, and expand the current by 199 times."

"."

After more than a dozen tests, the final results are presented on a piece of paper in the form of a table.

The stability of the electrical signal amplified by the silicon carbide transistor was beyond Han Yuan's expectations, and it also shocked the scientific researchers who were watching in the live broadcast room.

The three-digit current expansion effect is nothing, but the stability effect of the current expansion is extremely terrible.

The up and down fluctuations do not exceed five times, which is simply unbelievable.

If this is a crystal on an integrated chip, it is indeed possible to achieve this level.

But don't forget, this is an extremely simple silicon carbide transistor.

They watched the entire manufacturing process. The anchor did not use any high-precision instruments, nor did he use cutting-edge materials such as photoresist and single crystal silicon.

The highest level of technology is the use of 'electrothermal ion permeation' in the manufacture of N-drift layers.

"What if, say, this technology is applied to the silicon substrate of a chip?"

After the shock, a bold idea popped up in the minds of scientists who studied this aspect.

After all, the fabrication of the silicon carbide substrate of the transistor and the fabrication of the silicon substrate of the chip have the same steps to some extent.

For example, the implantation of aluminum ions and the erosion of trenches can all be applied.

More importantly, when the anchor made P-type silicon, he used polysilicon!
Although there is only one word difference between polycrystalline silicon and monocrystalline silicon, the manufacturing difficulty of the two is completely different.

If polysilicon can be used instead of monocrystalline silicon as the silicon base of the chip
Thinking of this, the breaths of all scientific researchers involuntarily became heavy.

In the simulated space, Han Yuan didn't know the shock that his experiment today brought to the outside world.

He is still busy testing the silicon carbide transistors and recording all the data.

The sun went down, and it was night.

The light in the physics laboratory has already been turned on, and after continuous testing, Han Yuan also successfully completed the test of the 'magnification ability' of this transistor.

As for the rest of the work, put it to tomorrow.

After all, there are not many targeted tests.

In addition to the amplification capability detection, he also needs to detect the reverse breakdown current of the silicon carbide transistor, voltage detection, Darlington tube detection, and limit parameter detection.

After successfully passing these tests, this transistor can be applied to a transistor computer.

These tests cannot be completed in a day or two, and may take more than half a month.

Moreover, he does not have some detection equipment in his hand and needs to manufacture them.

In addition, the targeted detection cannot be done by one silicon carbide transistor. He needs to manufacture dozens or hundreds of transistors of the same type to confirm that there is no problem with this manufacturing method.

So the Korean won is ready to spend the next month or so on this.

But in any case, the first silicon carbide electrical signal amplification transistor was successfully manufactured. With this foundation, the manufacture of other types of transistors will be much easier.

It's like climbing other mountains after you climb Mount Everest.

Although it is still difficult, the difficulty is no longer at the same level.

With excitement, Han Yuan stopped the live broadcast after saying hello to the audience in the live broadcast room.

After tidying up the laboratory and the overall information, he is going to go back and get some delicious food to reward himself.

It is already incredible that a silicon carbide transistor can be successfully manufactured in one manufacturing step.

Although this transistor has not yet passed the test, it is also worth celebrating.
