I, Yan Jiefang, will live to 2025 in this courtyard house.

Yan Jiefang went directly to the night shift supervisor and obtained all the information the supervisor had about the Baihe factory.

Based on this information, several key engineers and managers were subsequently located.

In less than ten minutes, I had a pretty good grasp of the factory.

The Shirakawa plant only produces silicon wafers (bare silicon substrates), not chips. It does not produce photoresist; the photoresist is produced by other Shin-Etsu plants.

This is Shin-Etsu Semiconductor's most advanced integrated silicon wafer manufacturing plant.

From pulling silicon ingots from the CZ single crystal furnace to slicing, grinding, polishing, and cleaning, the entire process is completed within the factory premises.

The factory also houses a semiconductor research institute, where new processes for eight-inch silicon wafers are being developed and ramped up.

The main product is 6-inch silicon wafers, while 8-inch wafers are still in the small-batch trial production stage.

The main functions and plant areas include: single crystal growth workshop (CZ Czochralski section), crystal rod processing-silicon wafer processing workshop (silicon rod → polished silicon wafer), ultra-clean testing and packaging workshop, Baihe Semiconductor Research Institute, and supporting public works.

According to information obtained from the person in charge, the factory covers an area of ​​more than 20 square meters.

The various equipment and facilities occupy a large area.

After receiving this information, Yan Jiefang knew that his one million cubic meter space was simply not enough to empty the place.

We can only pick out the useful ones to take with us.

There's nothing we can do about it. Who would have thought that a huge space that's 100 meters long, wide, and high would sometimes be too small?

This is just a world derived from a novel about courtyard houses!

This situation arises because his business is growing bigger and bigger, and he needs more and more things.

If you just stay cooped up in courtyard number 95 and argue with those characters in the story, a million cubic meters of space is definitely enough.

It would be easy to incorporate the entire courtyard into a personal space.

...

With the aid of his divine sense and spatial awareness, he could move things very quickly.

First, 12 state-of-the-art 8-inch CZ single crystal furnaces simply vanished into thin air.

Following that were 20 6-inch single crystal furnaces.

Next are the ingot cutting saws, external cylindrical grinders, internal cylindrical slicing machines, etc. in the silicon wafer processing workshop.

Then there are the RCA cleaning units, thickness/TTV/warpage interferometers, non-contact resistivity testers, etc. in the ultra-clean testing and packaging workshop.

Finally, there are the multi-media filters, ion softeners, primary and secondary reverse osmosis (RO) units, cation exchange beds, anion exchange beds, etc., in the various workshops of the peripheral supporting public works area.

The equipment involved in this entire project is numerous and complex; the examples above represent only a small portion of it.

If it weren't for the memories of those senior engineers, he wouldn't have known where to begin.

Even if you take action, you'll miss many inconspicuous but very important things.

After all, he hadn't learned this kind of knowledge and skills before.

After taking these things back, installing them properly and getting them to work is a huge undertaking for Yan Jiefang.

This is only if he has the space to cooperate.

Even with expert engineers providing guidance, it would take more than a year and a half to achieve stable small-batch supply if the installation is done in a normal, step-by-step manner!

This was under the condition that everything was going very smoothly.

If any problem occurs during the process, the time will be extended incalculably.

After packing up everything they needed, the factory workers had already noticed that many workshops and factory buildings had undergone major changes.

They all turned around and ran to report to their respective supervisors.

What's happening now is a very serious matter.

The value of those missing devices is so high that even selling them wouldn't cover the losses.

No one dares to or wants to take responsibility.

There are quite a few workers in this factory, and even with Yan Jiefang's current level of spiritual power, he wouldn't be able to deceive most of them.

Therefore, he could only transform into invisible wisps of smoke and beg for alms directly in front of the workers.

As for being seen by others, there's nothing he can do to stop it.

Subsequently, he caused major short-circuit accidents to occur in multiple workshops almost simultaneously.

As flames rose, the factory's management immediately organized workers to extinguish the fire and called the police.

Amidst the chaos, Yan Jiefang ascended to the sky, then rode his flying sword, Liefeng, which transformed into an almost invisible rainbow, and gracefully departed.

This incident caused a huge public opinion storm in the island nation, but it had nothing to do with the people playing Go at the Tokyo Go Association.

After all, they were just Go masters who came to play chess; it was impossible for them to instantly travel hundreds of kilometers to commit a crime at the Baihe factory.

After dawn on the 6th, Yan Jiefang and his son went to the airport with the national Go delegation and took a plane back to Beijing.

Afterwards, they rested at home for one night, and the next day Yan Xueqian continued to go south to work at the company.

Yan Jiefang stayed at home to continue recovering his spiritual power.

With all the equipment for producing silicon wafers ready, it's time to put advanced lithography machines on the agenda.

We also need to bring back all the equipment and technology for producing corresponding photoresists, specialty gases, wet chemical reagents, and thin-film sputtering targets.

A chip requires more than just silicon wafers and photoresist.

We also need a whole set of special gases: silane for growing thin films, phosphine for ion implantation doping, and carbon tetrafluoride for dry etching.

HMDS applies an adhesive bonding treatment to the silicon wafer, while TMAH developer reveals the exposed photoresist pattern.

Each layer of circuitry requires an expensive quartz mask.

Aluminum and titanium sputtering targets are used to sputter metal wiring, and dozens of electronic-grade acid and alkali solvents are used for cleaning.

The entire material supply chain is very long, and if the supply of key materials is interrupted, the production line will have difficulty operating normally.

These things are actually available in China, but the manufacturing quality is still somewhat lacking and cannot meet the stringent requirements of the latest equipment.

It needs more time to develop.

Yan Jiefang had no choice but to turn to his neighbors for help if he wanted to start the most advanced chip manufacturing process.

On April 10, he took a train south, this time heading to Weihai, Shandong.

This time, train number 247 was an evening train, and we arrived at Yantai Railway Station about 13 hours later.

It was a little after seven in the morning.

Yan Jiefang walked out of the train station with a canvas bag on his back, looking relaxed.

Yantai Railway Station must be very close to the coast; the occasional breeze seems to carry a faint hint of sea salt.

He found a secluded corner, took out a Cherokee, and drove towards Rongcheng City, which is located below Weihai.

As you can see on the map, this is the city in China closest to the Korean Peninsula.

According to the map, the distance between the two is less than 200 kilometers.

He could easily leap over it.
