Chapter XVIII

After the manufacture of this first batch of chips, Chen Yue summed up his experience, studied and improved, readjusted the parameters of the machine, and then began the manufacture of the second batch of chips.

At this moment, Chen Yue has given up the original 6000 nanometer manufacturing process, and only thinks about making chips with 10,000 nanometer process performance stably.

The 10,000-nanometer chip seems to be very backward, but it can still play a great role. Because in the industrial field, there are too many places where such advanced chips are not used at all.

For example, some control chips close to the bottom layer of the machine, its role may only be to receive a command, and then simply control the mechanical arm forward, backward, left and right, etc., how complex chips are needed?

Even a 10,000-nanometer chip is sufficient.

However, now Chen Yue has to apply the high-performance chips collected from the Mars base here. Because apart from these chips, he doesn't have anything else.

If you can manufacture stable and reliable 10,000-nanometer process chips, you can replace all the previous high-performance chips and use them in more critical places.

In fact, in the recent past, Chen Yue has taken the initiative to slow down the manufacturing speed of robots, just because the chip reserves are insufficient.

According to Chen Yue's estimates, in his current industrial circle, after the stable output of 10,000 nanometer process chips, it can replace at least one-tenth of the total use of current chips.

That's a lot of money and it can make a difference.

After some adjustments, this second batch of 1,000 chips, after adjusting the yield standard to achieve the performance of 10,000 nanometer process chips - its process is still the original 6,000 nanometers, but the performance can only reach the 10,000 nanometer process - the yield is no longer a pitiful, ironic zero, but finally reached 5%.

Fifty chips met the standard.

Chen Yue continued to improve, continue to study, and continue to adjust. After two years of repeated efforts, Chen Yue finally stabilized the yield at 55%.

This is already the limit. Limited by the stiffness of the instrument, the yield can no longer be higher than this.

In the past two years, Chen Yue has produced a total of about 20,000 chips that meet the standard, and gradually replaced them with various machines and robots to observe their performance and provide a basis for subsequent iterations.

After the yield stabilized, Chen Yue began to try to increase production. At the same time, the second chip production line began to be built.

This second production line is a new design based on the foundation and experience of Chen Yue's first production line.

In the past two years, Chen Yue's industrial base has also seen some growth. Various types of factories have become independent from the original customized general factories and have begun to realize the exclusive use of special factories. For example, specialized wire factories, tool factories, sulfuric acid plants, ethylene factories and so on.

Originally, the wire factory and the knife factory were even the same factory that involved metals. The multi-functional casting machine produces both wires and tools, which is very inefficient. Not anymore.

The growth of the industrial base gave Chen Yue more confidence and gave him enough confidence to build a second chip production line.

A new process of silicon purification plant, a new process of wet cleaning process, a new research and development of lithography machine......

When the second chip production line was completed, the first production line had reached the capacity of 10,000 chips per week, with a yield rate fluctuating between 50% and 55%.

The second production line started with an output of 10,000 chips, and the process is still 6,000 nanometers. But this time, Chen Yue finally doesn't have to lower the standard to measure the yield.

In the first trial production, among the 10,000 chips, the yield rate also reached 12% in terms of 6000nm process performance!

This means that every week, Chen Yue can produce 1,200 chips with 6,000 nanometer process by himself! It also means that every week, up to 1,200 high-performance chips can be replaced and installed in more important places.

And that's just the beginning of production. Chen Yue is confident that after two years of commissioning, the weekly production capacity of this second production line will reach 100,000 pieces, and the yield rate will reach 40%! In that case, it will be 40,000 pieces per week.

The sufficient supply of chips completely let go of the shackles on Chen Yue, so that he can finally go all out to produce robots and equipment at any cost without worrying about the lack of chips available.

As a result, all the previously suppressed robot production capacity was released. Under the premise that there are nearly 100,000 robots at this moment, the robot production capacity has reached an average of 700 units per day!

The newly produced robots are continuously supplied to the construction line. The overwhelmed robots can finally take a break and have a chance to go to the "hospital" for a complete overhaul. At the same time, the construction progress on all fronts has also begun to speed up suddenly.

At this moment, the railway network built by Chen Yue on Europa has expanded from the original one horizontal and two vertical to the current three rings and four verticals.

With the Glowing spacecraft as the core, there are a total of three loops around it, with a distance of about 50/160/280 kilometers. Among the three loops, there are also four longitudinal railways connecting the inside and outside.

There are also a large number of branch lines in the railway network, which extend to every mine and factory. The total length of railways has now reached 7,000 kilometers.

There are more than 200 trains that fly around the clock on these tracks. They transport steel ingots, copper ingots, aluminum ingots, etc. to the corresponding foundries and processing plants, or machined parts to assembly plants, or large quantities of solid oxygen to power plants, or large quantities of railroad tracks to the end of the railway......

Chen Yue observed that with the increase of his industrial strength, along with the continuous increase in the number of factories and production capacity, the environment of the entire Ganymede has also been affected by himself.

At this moment, Ganymede even has a thin atmosphere.

A small celestial body like Europa wants to have an atmosphere, which is hilarious. Even if there is an occasional coincidence, such as passing through an interstellar gas rich area and having a little atmosphere, it is like an honest man marrying a little fairy, and he can't keep it at all.

Interstellar radiation, Jupiter radiation, will ruthlessly strip the atmosphere at an extremely fast rate.

However, Chen Yue found that Europa's atmosphere was getting thicker and thicker......

Its surface atmospheric pressure even reaches 1/70,000 of the Earth's atmospheric pressure. Larger than Pluto's atmosphere.

You know, it's much smaller than Pluto.

Chen Yue looked at the power plant that was spewing billowing smoke and dust all the time, and then looked at the steel plant and metallurgical plant that were non-stop all the time, thoughtful.

"Where there's atmosphere, there's atmosphere...... Just don't be too thick. ”
