Chapter 270 Manufacturing of Wafer

Tang Fei's eyes were full of joy, and he looked down.

After a few glances, Tang Fei walked over there, and Liu Shiwei quickly followed.There is a newly built road over there, leading to the sea.

The villa is about 300 to [-] meters away from the seaside. In just a few minutes, Tang Fei came to the seaside. Looking at the vast sea and feeling the gentle sea breeze, he felt extremely refreshed.

I didn't expect my villa to be so close to the sea, a real sea view room.

What surprised Tang Fei just now, except that after seeing the vast sea, Tang Fei was pleasantly surprised to find that there was actually a marina for yachts.

You don't need to ask, the yacht marina under construction is its own private marina, which is matched with this villa. If you have a yacht in the future, you can dock at this marina. When you have time, you can drive the yacht to sea.

"Shiwei, this place is really nice!"

Seeing that Tang Fei was very satisfied, Liu Shiwei said: "Brother Fei, this is our villa king, this is the exclusive pier of the villa king, and it will also be your private pier."

After looking at the pier, Tang Fei was extremely satisfied, and walked up the hillside along the newly built beautiful road. After walking about two to 300 meters, he arrived in front of his big villa.

Liu Shiwei suggested: "Brother Fei, go in and have a look, how about it?"

That's exactly what Tang Fei meant. The main body of the villa has been built, which means that the rough has been built, and the exterior wall decoration, water and electricity installation and other work will be carried out. You can go in and have a look.

Under the leadership of Liu Shiwei, Tang Fei walked into the gate of the villa.When entering the gate, there is a garden first, and the area is not small. In the future, beautiful flowers and trees will be planted here, and professional gardeners will also take care of it.

Through the garden, into the big villa.Liu Shiwei introduced to Tang Fei: "Brother Fei, the villa has three floors. The first floor is mainly the garage, servant's room, hall and kitchen. The second and third floors have sixteen bedrooms and eight bathrooms. There are three large study rooms, as well as cloakrooms, etc. There are a total of more than 30 large and small rooms..."

Under the leadership of Liu Shiwei, Tang Fei took a good tour of the villa. In the master bedroom on the third floor with an area of ​​nearly [-] square meters, looking outside, he could see the vast blue sea in the distance.

Living in such a villa in the future will be a top-notch enjoyment.

The villa also has a larger back garden, where many beautiful flowers and trees will also be planted.In addition, there is a private swimming pool in the back garden.

After looking around, Tang Fei was extremely satisfied.

Liu Shiwei said: "In two to three months, this villa will be fully built and enter the decoration stage. A large number of flowers and trees will also be planted in the front and rear gardens. Brother Fei, do you have any requirements for the decoration of the villa? ?”

Tang Fei smiled and said, "Let's adopt the Chinese decoration style."

"Okay, I will ask the designer to make a few more designs, and we will decorate according to which one you are satisfied with."

After looking around in the villa, the time came to noon unknowingly.Liu Shiwei drove to a very nice restaurant.

Liu Shiwei's family deserves to be the owner of a restaurant. The place he chose to eat is first-class, the dishes are exquisite, the taste is good, and the environment is also very good. Tang Fei is very satisfied.

After eating, Liu Shiwei said: "Brother Fei, we can go to Wanheng Real Estate Group now."

It used to be called Wanheng Real Estate Company, and it was temporarily rented in a well-known high-end office building.Now it is renamed as Wanheng Real Estate Group.

Walking into Wanheng Real Estate Group, Tang Fei found that the scale of the place was even bigger. Liu Shiwei rented out the entire office building, and there were more office workers in it. Wanheng Real Estate Group has developed very well, although it is not the top one in Shenhai City Real estate company, but it is already striding forward to a first-class real estate company.

Liu Shiwei took Tang Fei into the largest and most luxurious office here.This has always been an office prepared for Tang Fei, but Tang Fei hasn't come here a few times throughout the year.

The office is tidied and cleaned by a special person every day, clean and tidy.After sitting down on the sofa in the office, Liu Shiwei reported to Tang Fei the recent situation of Wanheng Real Estate in detail.

He also reported one of his ideas to Tang Fei, that is, he wanted to go public.

The real estate market in Shenhai City is so good, if there is a lot of funds in hand, it will definitely develop better and faster!
Liu Shiwei is eager to have a large amount of funds, preferably several billion, tens of billions of funds, so that he can take down several pieces of land he fancy, and then develop them into high-end real estate one by one.

The purpose of listing is mainly to collect money so that Wanheng Real Estate can have more abundant funds and develop faster.

Opportunity waits for no one. If you don’t hurry up, you will be preempted by other real estate companies. They eat meat, but you can only eat soup.

The key is to have strong funds in hand, and Liu Shiwei has a plan to go public.Tang Fei was specifically asked for his opinion.

For those powerful real estate companies, at least nine of the ten real estate companies are the boss companies, and one is preparing to go public.

Tang Fei was not opposed to going public. He asked Liu Shiwei about some of his plans and ideas, and agreed: "Since you have ideas and plans, then prepare for the listing and strive for an early success."

Seeing that Tang Fei agreed, Liu Shiwei was overjoyed!
He also reported a piece of good news to Tang Fei. He is operating the land on Shennan Avenue and has great hopes of winning it.

With such a good location, a Grade A office building can be built in a prime location like Shennan Avenue. The tenth floor is a Grade A office building.

Tang Fei also hopes to take this land down.

Hearing such good news, Tang Fei was extremely happy, and said with a smile: "This is really good news. If this land can be taken down, we will build skyscrapers. In the future, the headquarters of Jiuzhou Industrial Co., Ltd. will move into This building."

..........
Not far from the chip base, there is an office building with a good environment.

The entire floor of this office building was leased by a company two months ago for half a year.In this layer, many people are busy.

Wang Xingkui, Dong Bo, Ma Weijun, and Hao Hongxia, four experts, were having a meeting in the conference room. In the morning, they went to the chip base together and saw a lot of equipment, including wafer production equipment and optical chips needed for chip production. engraving machine.

All four of them knew that this must be the boss's big hand, and some technicians had been arranged to cooperate with a very powerful equipment installation company to start the equipment installation.

The equipment was already in place. After talking about the equipment for a while, the four of them began to exchange some things about the chip design.

For some design technical issues, the four will usually sit down to discuss and discuss together, and for some important design technical materials, the four will personally review them.

It was the same today, the four of them were discussing some technical problems encountered in chip design.The four are experts, and with the simple version of the system design information, some technical problems encountered were quickly resolved.

Then, the four talked about wafer manufacturing.Soldiers and horses do not move food and fodder first. Before manufacturing chips, wafers must first be manufactured. Wafers are indispensable for chip manufacturing.

The preparation of wafer production process data is ready to start, and the whole set of production equipment is in place, so the problem of compiling process data is not a big problem.

The manufacturing process of wafers is that silicon dioxide ore is refined by electric arc furnace, chlorinated with hydrochloric acid, and distilled to produce high-purity polysilicon with a purity as high as 99.999999999%.

The wafer manufacturing plant melts the polysilicon again, and then mixes a small silicon crystal seed into the solution, and then slowly pulls it out to form a cylindrical monocrystalline silicon rod. Since the silicon crystal rod is made of a Small crystal grains are gradually formed in the molten silicon raw material, and this process is called "grown crystal".

After the silicon ingot is ground, polished, and sliced, it becomes the basic raw material of the integrated circuit factory - the silicon wafer, which is the "wafer".

To put it simply, monocrystalline silicon wafers are drawn and refined from ordinary silica sand, and after a series of measures of dissolution, purification, and distillation, they are made into monocrystalline silicon rods. After the single crystal silicon rods are polished and sliced, they become wafers.

The wafer is processed by multiple photomasks, and each step includes photosensitive agent distribution, exposure, development, corrosion, infiltration or evaporation, etc., to make an IC wafer with multi-layer circuits and components, and then handed over to the post- Segment testing, cutting, and packaging plants to make physical integrated circuit products.

Wafer is the raw material for manufacturing chips, and it is also what is needed for the manufacture of integrated circuit products.The market prospect of this kind of thing is very broad, and the market demand is very large.

The chip base has a complete set of advanced wafer production and manufacturing equipment. It will definitely produce wafers. In addition to its own use, some of them will be sold to the outside world in the future.

Together, the four experts will basically determine the production process for manufacturing wafers, and then arrange the following technicians to compile detailed process technical information.

The equipment for manufacturing wafers is very complete. This is something produced by the system. It also includes wafer inspection equipment, such as wafer microscope inspection systems.

The microscope platform can perform precise inspection, and can observe microscopic particles, scratches, contamination, etc. of the wafer.It can also provide a variety of flexible wafer detection modes, including the following detection content: wafer ID, wafer notch direction, wafer rotation angle and speed, wafer microscopic lattice, etc., and can realize continuous monitoring .

Together, the four experts determined the wafer production process and testing process.

At this time, there was a knock on the door of the meeting room, and a technical supervisor pushed in and reported, "Expert Wang, the boss is here."

"Ah, the boss is here in person." Wang Xingkui was pleasantly surprised, and immediately announced the end of the meeting. The four of them left the conference room together, and soon saw Tang Fei.

....
Two updates today, the second update is over, thank you everyone!
Arrive home this evening, start tomorrow, work hard to code, try to change three times a day.
