Soon, three more people came to the office.

After a brief greeting, Li Zetian asked, "Do you remember Game-atch?"

Everyone nodded, thoughtful.

"Of course, it was Mr. · Li, the game products you designed, once swept the world!"

Li Zetian nodded and said, "I redesigned a product on the basis of Game-atch this time. As we all know, Game-atch can only play one game per machine, and the defects are huge, but the new product has been improved!"

After finishing speaking, he turned his head to look at Dongfang Yuqin and motioned for her to take out the product design information.

Dongfang Yuqin took out the documents from her bag, then walked to the printer on the side to make a few copies, and finally sent a copy of the information to everyone.

"Gameboy?" said Nolan Bushnell.

Li Zetian smiled, that's right, it is the core product that Nintendo relied on in his previous life, Gameboy, as soon as this product came out, the whole world went crazy! In his previous life, the product was developed by Yokoi Junhei, but Yokoi Junhei himself later admitted that because of objective conditions and market demand, Gameboy lowered its requirements in many places, and it was not his ideal work.

Li Zetian looked at Yokoi Junhei quietly, thinking, let you develop this time, see what kind of perfect work you can develop!

After 10 minutes, Li Zetian asked: "Everyone hasn't seen much production, is there a problem?"

Everyone shook their heads, all shocked by Li Zetian's design, where there was any problem.

Nolan Bushnell said, "Mr. · Li, the design of the Gameboy is fantastic, especially the design of the interchangeable game cards, which is definitely loved by players!"

"Yes, interchangeable game cards, which means that one console can play multiple games! Game-atch can only play one game, which players don't think is cost-effective. ”

"It's just that in Mr· In Li's design, the Gameboy is very thin and light, which is probably a huge problem we will face in the development process!"

“……”

Everyone analyzed.

Li Zetian nodded with a smile and said: "That's right, but to realize the game function, the game console itself must be beautiful and easy to carry, and the lighter and thinner the machine, the more popular it is!"

As he spoke, Li Zetian looked at Yokoi Junping, "The hardware development project of the Gameboy will be handed over to Yokoi Junping, and you will be responsible for it......"

"Okay, Mr. Li。 ”

Yokoi Junhei was excited and hurriedly agreed.

Li Zetian smiled at him, Yokoi Junhei has always been the main person in charge of the hardware department of Flamingo Company, and the first and second generations of Flamingo were developed under his leadership, although he is an RB person, but who said that RB people can't be used for themselves?

Gunpei Yokoi has now applied for U.S. citizenship and is a Japanese American.

……

……

Christmas is coming in a blink of an eye, and the company has begun to take annual leave, and many people are ready to travel abroad during Christmas, and Li Zetian's family is no exception.

Li Zetian plans to go back to China, but he hasn't been back for many years.

In addition, the investment link in Chinese mainland has been greatly improved, and Chinese real estate has already entered the Chinese mainland market, which has been fruitful.

Li Zetian and Yu Jingqiu took their two children to Hong Kong to meet their parents and Zhou Qiqi, and then went to Chinese mainland together.

After coming to Hong Kong, Li Zetian also took time to go to the Science and Technology Park to have a look, and also chatted with Zhang Zhongmou about Intel's "wafer foundry" factory.

At present, this wafer fab belongs to a 4-inch wafer fab with a process of 0.55 microns, which is already a very advanced wafer fab.

In the semiconductor industry, people often hear people talk about how many inch wafer factories and how many processes there are, which are actually two concepts.

As we all know, the wafer is silicon, the material is usually sand, and turning sand into silicon requires a two-stage purification process, the first step is metallurgical-grade purification, to obtain the high-purity polysilicon required for the semiconductor process, with a purity of 99.999%. The second step is to pull the crystal. First, the high-purity polysilicon obtained earlier is melted to form liquid silicon, and then the silicon type of single crystal is in contact with the liquid surface, and slowly pulled up while rotating, and finally a neatly arranged monocrystalline circular silicon pillar is formed, which is why the fab is called a wafer factory.

4 inches is the diameter of the monocrystalline silicon column, and the larger the size, the higher the speed and temperature requirements for crystal pulling, and it is difficult to make wafers of more than 4 inches with current technology. Of course, 5 inches and 6 inches are not impossible to make, but the cost is too great and not cost-effective, and 4 inches is currently more mature and can be commercialized.

A wafer can be cut into multiple chips, so the larger the size, the larger the wafer area, the more chips are produced per unit time, and the wafer area of the 8-inch wafer factory is 4 times the wafer area of the 4-inch wafer factory, which can greatly reduce the production cost, so the larger the wafer fab can completely crush the wafer fab with low size in terms of price.

As for the "process", it has a lot to do with the lithography machine. To put it simply, the lithography machine is to draw an integrated circuit on the chip, the smaller the process, the more things can be depicted on the chip in the same area, and the stronger the performance of the chip, which is also the basis of Moore's Law.

Li Zetian is involved in the semiconductor industry, so he naturally has a little understanding of these.

The size and process of the fab are tied to the production equipment, and Applied Materials and Esmore are responsible for solving these problems.

Zhang Zhongmou is in the wafer factory, and Li Zetian is not worried about any problems.

On the morning of December 26, the family set off for Chinese mainland.

Coincidentally, not long after Li Zetian's family got off the plane, it snowed in Hangzhou, and the flying snow soon covered the whole Hangzhou with a layer of white clothes, Hangzhou is like a painting, and the beauty is intoxicating.

This is Li Zetian's second time in Chinese mainland after crossing over.

The reason why there are so few people is mainly a political issue.

Li Zetian's identity is too sensitive, and he often comes to China, which has a bad influence and is easy for the United States and the Western world to misunderstand. In addition, a few years ago, the reform of Chinese mainland had just begun, and many people were not politically conscious and had a hostile attitude towards Li Zetian, a big capital. Now that it is almost 1985, China's economy is taking off, people have great confidence in reform and opening up, and their attitude towards the capitalists has also decreased, and they have even begun to worship foreign countries...... Not only ordinary civilians, but even officials are like this, seeing foreigners, they feel that they are three points shorter, and they have to curry favor with them.

Li Zetian felt these things very deeply in this life, and these leaders in Hangzhou were even eager to offer him up, and this time they learned that he was going to visit relatives in Hangzhou, and the airport was full of leaders, as if they had come to greet foreign presidents, which was particularly grand.
