Humanity is missing, luckily I have billions of clones

Two dimensions are planes, and three dimensions are solids.

The original transistors were "engraved" on silicon wafers through photolithography. If they are changed to three-dimensional, it is similar to "building" transistors on the chip.

The technical difficulty is obviously increased many times.

"The multiple exposure technology I developed earlier seems to be just right for use in lithography of three-dimensional transistors. Let's give it a try first."

There is no need to go through complicated application procedures, no need to communicate, no need to collect resources. Li Qingsong just got this possibility the second before, and at this second, Li Qingsong made the decision directly.

So many clones who were trying other solutions immediately put down their work and joined in trying this possibility.

The relevant resources needed to carry out this attempt were immediately in place without any delay, and the entire process was extremely efficient.

After the preliminary design was completed, the experimental multiple exposure equipment immediately began to etch a silicon wafer in the laboratory. Then there was a series of testing processes.

When the final result was presented in front of Li Qingsong, Li Qingsong widened his eyes with joy.

“It actually works!”

After changing the transistor from two-dimensional to three-dimensional, the short channel effect disappeared! The performance of the transistor and the stability of the current were improved again!

"That's it!"

Less than half a month had passed since this idea came up, and based on the experimental data at the moment, Li Qingsong made a major decision that was enough to change the direction of the entire industry.

Three-dimensional transistors undoubtedly have higher performance, but it also means a problem.

That is, the technical difficulty has been greatly increased compared to before, and accordingly, if this technology is used, the manufacturing process will also be greatly extended.

From the purification of silicon wafers to the final chip packaging, the entire process involves more than 1,700 steps!

Assume that the yield rate of each of the 1,700 processes is 99% - this seems quite high. But in fact, after 1,700 processes, the yield rate of the final product is only 3.8 billionths, which is completely unusable.

Only when the yield rate of each process is increased to about 99.99%, the final yield rate can be increased to about 80%, which can be considered practical.

But achieving a 99.99% yield rate in every process...how difficult it is.

But there was no other way. Li Qingsong could only follow the most stringent design and construction requirements to build this brand new chip factory.

Li Qingsong finally chose a site in a basin far away from any bases and railway lines, so as to ensure that even the slightest vibration would not be transmitted here;

The factory buildings of this huge factory have adopted the most stringent anti-radiation measures to prevent interstellar radiation from interfering with the production line;

Every clone who enters the production workshop must wear the most stringent dust-proof clothing to prevent bringing in any dust, etc.

The construction of this huge factory and the installation and debugging of subsequent equipment took Li Qingsong a total of one year.

Although a year may not seem like a long time, for the extremely efficient Li Qingsong, it is a rare long time.

The chip factory was finally built and can finally mass-produce advanced chips with a process of 20 nanometers.

However, we have just mastered this technology, and at this stage, the yield rate of the chip factory cannot be increased for the time being, and is currently only about 3%.

Its total production capacity is 10 million chips per year, but only 300,000 chips meet demand, and the remaining 9.7 million chips have problems of one kind or another, resulting in a decline in overall performance.

Throw these chips away? Recycle them?

What a joke!

If there is a defective part of the chip, we can block it through algorithms and programs, and the remaining part can still be used, right?

Although the overall performance will decline, even if it does, the comprehensive performance is higher than even the most advanced 45nm process chip before, so it is still a good thing.

Therefore, Li Qingsong used all 300,000 of the highest quality chips produced that year to build a new supercomputer, and the remaining 9.7 million chips were all distributed to factories and bases, as well as various spacecraft and vehicles.

With continuous production, optimization and adjustment, the overall yield rate is slowly increasing. I believe it won’t be long before it can be increased to more than 90%.

Now with the supply of more advanced chips, Li Qingsong finally built the new supercomputer he had always dreamed of.

Compared with the previous generation of supercomputers, this one uses more chips, reaching 160,000!

Its computing power has reached 130 quadrillion floating-point operations per second, which is more than 30 times that of the previous generation of supercomputers!

After the construction and debugging were completed, Li Qingsong couldn't wait to put the combat AI, which had previously been severely limited in performance, into this supercomputer and start combat experiments again.

This time, Li Qingsong adopted a different fighting method from last time.

His real body also came to the training ground, controlling Party A's fleet almost without delay. At the same time, he consciously delayed the control of Party B's fleet, giving it a 100-second delay.

But Party B’s fleet has a supercomputing spaceship that can receive real-time assistance from combat AI.

In this way, one side had no combat AI but also no delay, and the other side had combat AI but also had delay. Both sides used blank bullets and simulated weapons and engaged in fierce fire in space.

With the application of new supercomputers, it is visible to the naked eye that Party B’s fleet has seen tremendous improvements in flexibility, reaction speed, coordination, and cooperation capabilities.

Various tactics were performed in turn, such as advance, formation, volley, cover, suppression, etc. At the same time, weapons such as bullet torrents, artillery, interstellar missiles, electromagnetic bombs, etc. were used in turn.

In the end, the Party A fleet directly controlled by Li Qingsong still won this battle.

But winning was not easy.

According to comprehensive evaluation, when the delay reaches 100 seconds, with delayed control and combat AI assistance, the combat effectiveness of Party B's fleet can reach about 90% of Party A's fleet.

Li Qingsong did not stop and started the experiment again.

This time, he increased the delay of Party B's fleet to 500 seconds.

In another battle, Party B's fleet showed a clear decline in combat effectiveness. After final evaluation, its overall combat effectiveness was only about 70% of Party A's fleet.

However, if there is no combat AI assistance and it relies entirely on itself to control the fleet with a 500-second delay, its overall combat effectiveness will plummet to only about 30%.

Among them, the combat AI provides a 40% increase in combat effectiveness!

"A 500-second combat delay corresponds to a combat radius of about 75 million kilometers.

From this moment on, with the assistance of combat AI, I can exert 70% of the fleet's peak combat power even if the spacecraft is 75 million kilometers away!

That’s enough! ”
