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

Besides lithography machines, other related industries in China that manufacture chips are also making great strides.

Significant progress has been made in various related areas, including 6-inch silicon wafers, photoresists, special ultrapure reagents, spin coaters and developers, ion implanters, photomasks, and ultrapure water systems.

We have barely caught up with the international level of photolithography.

It is believed that these items restricted by the COCOM agreement will soon be officially available for sale in China.

At that time, Yan Jiefang's PAS2500 lithography machine, which he had worked with in the special economic zone for several years, would lose all its advantages.

"We need to start fundraising for some more advanced equipment in advance."

Yan Jiefang thought to himself.

He had actually already found another job.

There was no one else but ASML; after all, he just remembered that company.

It's a pity this guy is so disappointing!

According to the information he obtained, they produced the PAS 5500/100 (i-line 0.35μm, 8-inch) lithography machine in 1991.

However, after evaluation and verification by IBM, they were not satisfied with the results.

The cancellation of a large number of subsequent orders dealt a significant blow to ASML.

Although it did not collapse completely, its development speed had to be slowed down considerably.

When Yan Jiefang saw this information, he was both furious at their lack of ambition and saddened by their misfortune!

However, he still did not give up on the PAS 5500/100 lithography machine.

After all, the company's employees are already used to the PAS2500, so it's naturally easier for them to use products from the same series.

Therefore, he plans to get two PAS 5500 systems to try them out.

After all, the workshop that has already been built can't just be left empty forever, right?

In addition to ASML, the most advanced lithography machines currently on the market are actually assembled by Nikon and Canon.

They are NSR-1755i7A (Nikon) and FPA-2000i1 (Canon).

NSR-1755i7A:

Light source: i-line 365nm mercury lamp, 5x smaller

NA=0.5, mass production resolution 0.5μm, limit 0.4μm

Wafer: Maximum 6 inches (150mm)

Application: Mass production of 16M DRAM

FPA-2000i1:

Light source: i-line 365nm, 5x smaller.

NA=0.45, mass production 0.55μm, limit 0.45μm.

Wafer: 6-inch wafer

Yan Jiefang already knew these parameters by heart.

He wondered if he should bring some back first to maintain the advanced nature of his company's chip manufacturing process.

This matter really cannot be delayed for too long.

In addition, the workshop at Changxin Electronics will be completed in a few months, and we also need to prepare a complete set of equipment to produce 8-inch polished silicon wafers in advance.

However, all these high-tech manufacturers are located overseas, so acquiring them will require careful planning.

Yan Jiefang looked around at the equipment and finally pointed to the locations of Japan and South Korea.

We can only try to find a solution in these places.

The Fujitsu Cup is starting next month, and our leader, Yan Xueqian, will continue to participate in this year's competition.

The competition venue is in Tokyo, which is not far from Fukushima.

Just go with him then.

He stayed home and rested until the end of March before buying a plane ticket from Beijing to Huangtian Airport in the Special Economic Zone, and came here directly.

Compared to taking a train or flying to Baiyun Airport and then transferring, it's much more convenient and faster now.

It only takes about three hours to get there.

The only problem is that plane tickets are extremely difficult to obtain.

Fortunately, these were minor matters for Yan Jiefang.

In early April, the father and son flew from Kai Tak Airport to Tokyo.

Here, they joined the rest of the national Go team.

这次比赛时间有两轮，分别是R1（24→16），时间是4月3日举行。

R2（16→8），4月5日举行。

Both are located at the Nihon Ki-in in Tokyo.

As the previous Fujitsu champion, Yan Xueqian and the other eight seeded players do not need to participate in the first round and can directly participate in the second round of the round of 16.

They arrived in Tokyo on April 2nd and will stay here for four nights until the competition ends on the 5th.

Therefore, Yan Jiefang had four opportunities to explore the Futian Baihe factory.

Last month, after identifying his target, he began preparing for the plan.

The Shirakawa plant is Shin-Etsu Chemical's core silicon wafer production plant.

It is located in Nishigo Village, Nishishirakawa District, Fukushima Prefecture.

Production began in 1984.

It is currently the main production plant for 8-inch silicon wafers in the island nation.

It can complete the entire process of single crystal, slicing, and polishing in one integrated production.

These are exactly what Yan Jiefang needs.

This is a perfect opportunity to wipe them all out in one fell swoop.

If Seoul weren't so far from Tokyo, he would have liked to go there for a visit.

However, that place is very close to a city in Shandong, China, so it would be better to find an opportunity to start from there later.

While he was thinking about something, he also picked up a detailed map of the island nation from a bookstore on the roadside.

Although the book was in Japanese, Yan Jiefang had no trouble reading it.

After all, he had already learned 99/100 of Japanese nearly 30 years ago.

No native speaker from any island nation speaks Japanese as authentically and accurately as him.

Yan Jiefang, like any other person, accompanied the delegation to visit the Japan Go Association in Tokyo, and then returned to the hotel that the event organizers had prepared in advance.

In the latter half of the night, he turned into a wisp of smoke and disappeared from the hotel.

According to the map, Fukuda is about 400 to 500 kilometers away from Tokyo.

As long as he is heading in the right direction and has enough spiritual energy in his body, he can make a round trip.

After quickly discerning the direction, he rode his flying sword across the sky.

The first search did not go smoothly.

Because of a slight deviation in direction, although he arrived in Futian, he didn't have enough spiritual energy left to go to the Baihe Factory to beg for alms.

There was no other way but to randomly grab a few people of a certain status in the city and get the factory's detailed location.

There won't be any mistakes when we take action in a couple of days.

Upon returning to the hotel, he immediately took out the spirit stone to restore his spiritual power.

As soon as it got light, the first round of the competition began on time.

Yan Jiefang only stayed at the chess academy for an hour or so before making up an excuse to return to the hotel.

He needs to recover his spiritual power as soon as possible to prepare for the next move.

On April 5, Yan Xueqian easily defeated his opponent to advance to the round of 16.

In the latter half of the night, Yan Jiefang, who had already made preparations, set off again.

As expected, we arrived above the workshop of the Baihe factory.

Even in the middle of the night, the factory was still operating normally and did not stop production.

Many workers who work the night shift are still working in the workshop.

This situation was exactly what he had anticipated.

Therefore, this operation needs to be planned in advance and then acted quickly to avoid any unexpected situations.
