Chapter 270: Fabrication of Wafers

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

After taking a few looks, Tang Fei walked towards that side, and Liu Shiwei hurriedly followed. There was a newly built road that led to the sea.

The villa is about two or three hundred meters away from the sea, and in just a few minutes, Tang Fei came to the beach, looking at the vast sea, feeling the gentle sea breeze, and feeling extremely comfortable.

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

What was it that made Tang Fei so surprised just now, in addition to seeing the vast sea, Tang Fei was pleasantly surprised to find that there was actually a yacht dock.

You don't have to ask to know that this marina under construction is its own private marina, and this villa is matching, if there is a yacht in the future, you can dock in this marina, and when you have time, you can drive the yacht out 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 dock of the Villa King, and it will also be your private dock." ”

After taking a look at the wharf, Tang Fei was extremely satisfied, and walked up the hillside along this newly built beautiful road, about two or three hundred meters, and walked in front of his big villa.

Liu Shiwei suggested: "Brother Fei, go in and take a look, how about it." ”

Tang Fei has this meaning, the main body of the villa has been completed, that is to say, the blank has been built, and the exterior wall decoration, water and electricity installation and other work will be carried out, and you can go in and have a look.

Under the leadership of Liu Shiwei, Tang Fei walked into the gate of the villa. The entrance to the gate is first and foremost a garden, which is not small, where beautiful flowers and trees will be planted in the future, and it will also be tended by a professional gardener.

Walk through this garden and into the big villa. Liu Shiwei introduced Tang Fei: "Brother Fei, the villa has three floors, the first floor is mainly a garage, a maid's room, a hall and a kitchen, etc., the second and third floors have a total of 16 bedrooms, eight bathrooms, three large study rooms, and cloakrooms, etc., there are more than 30 large and small rooms......

Under the leadership of Liu Shiwei, Tang Fei took a good tour of this villa, in the master bedroom with an area of nearly 100 square meters on the third floor, looking outside, you can see the vast blue sea in the distance.

In the future, I will feel that it is a top pleasure to live in such a villa.

The villa also has a larger rear garden, which will also be planted with a lot of beautiful flowers and trees. 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 or 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, Fei Ge, 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 do a few more sets of design plans, which one you are satisfied with, we will decorate according to which set. ”

After a look at the villa, the time unconsciously came to noon. Liu Shiwei drove and went to a very nice restaurant.

Liu Shiwei's family is worthy of opening a restaurant, the place he chose to eat is first-class, the dishes are very exquisite, the taste is also 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 has been renamed Wanheng Real Estate Group.

Walking into Wanheng Real Estate Group, Tang Fei found that the scale here is larger, Liu Shiwei rented the entire floor of the office building, and there are more office staff inside, Wanheng Real Estate Group has developed very well, although it is not the top real estate company in Shenhai City, but it is already moving towards a first-class real estate company.

Liu Shiwei took Tang Fei into one of the largest and most luxurious offices here. This has always been an office prepared for Tang Fei, but Tang Fei has not been here a few times throughout the year.

The office is sorted out and cleaned every day, clean and neat. After sitting down on the sofa in the office, Liu Shiwei reported to Tang Fei in detail about the recent situation of Wanheng Real Estate.

He also reported to Tang Fei an idea of his own, that is, he wanted to go public.

The real estate market in Shenhai City is so good, if you have a lot of money in hand, you will definitely be able to develop better and faster!

Liu Shiwei is eager to have a large amount of funds, preferably billions or tens of billions of funds, so that he can take down several pieces of land that he fancies, and then develop them into high-end real estate one by one.

The purpose of listing is mainly to make money, so that Wanheng Real Estate has more abundant funds and can develop more rapidly.

The timing will not wait for anyone, if you don't hurry up, you will be preempted by other real estate companies, people eat meat, you can only drink soup.

The key is that you must have strong funds in hand, and Liu Shiwei has a plan to go public. I specially asked Tang Fei's opinion.

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

Tang Fei was not opposed to going public, asked Liu Shiwei about some plans and ideas, and agreed: "Since you have ideas and intentions, then prepare for the listing and strive for the success of the listing as soon as possible." ”

Seeing Tang Fei agree, Liu Shiwei was overjoyed!

He also reported to Tang Fei a good news that he was operating the land on Shennan Avenue and had great hopes of taking it down.

With such a good location, you can build a Grade A office building in a prime location like Shennan Avenue, with a super shopping plaza on the lower floors, a super five-star luxury hotel on the dozens of floors below, and a Grade A office building on the top dozens of floors.

Tang Fei also hopes to take down this land.

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

……….

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

An entire floor of this office building was rented by a company two months ago for a period of six months. Within this level, a lot of people are busy.

Wang Xingkui, Dong Bo, Ma Weijun and Hao Hongxia, four experts, were having a meeting in the conference room, and in the morning, they went to the chip base together and saw a large number of equipment, including wafer production equipment and lithography machines needed for chip manufacturing.

The four of them all know that this must be the boss's big deal, and some technicians have been arranged to cooperate with a very powerful equipment installation company to start the installation of equipment.

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

Some technical issues in the design, the four people will generally sit down to discuss and discuss together, and some important design technical information, the four people will personally review.

Today, too, the four of them discussed some of the technical problems encountered in chip design. The four of them are experts, and there is a simple version of the design data, and some technical problems encountered are quickly solved.

Then, the four of them talked about wafer manufacturing. Before the production and manufacturing of chips, the first thing to do is to produce wafers, and wafers are indispensable for the production and manufacturing of chips.

Wafer production process data has been prepared to compile, the whole set of production equipment has been put in place, and the problem of compiling process data is not big.

The production process of wafers is that the silica ore is refined by an electric arc furnace, chlorinated with hydrochloric acid, and distilled to make high-purity polysilicon with a purity of up to 99.9999999999%.

The wafer fab then melts the polysilicon, then does a small grain of silicon crystal seed into the solution, and then slowly pulls it out to form a cylindrical monocrystalline silicon rod, which is called "crystal growth" because the silicon crystal rod is gradually generated by a small grain in the molten silicon raw material.

After grinding, polishing and slicing, the silicon crystal rod becomes the basic raw material of the integrated circuit factory - silicon wafer, which is the "wafer".

To put it simply, monocrystalline silicon wafers are extracted from ordinary silica sand, and monocrystalline silicon rods are made into monocrystalline silicon rods after a series of measures such as dissolving, purification and distillation.

Wafers are processed by multiple masks, each of which includes photosensitive coating, exposure, development, corrosion, penetration or steaming, etc., to make IC wafers with multi-layer lines and components, and then handed over to the back-end testing, cutting, and packaging factories to make physical integrated circuit products.

Wafers are the raw materials for the production and manufacture of chips, and they are also the things needed for the production and 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, which must be produced and manufactured, in addition to being used for their own use, some of them will be sold to the outside world in the future.

The four experts together will basically determine the production process of manufacturing wafers, and then arrange the following technicians to compile detailed process technical data.

The equipment for the production and manufacturing of wafers is very complete, which is something produced by the system, and it also includes the inspection equipment for wafers, such as the microscope inspection system for wafers.

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

Together, the four experts determined the production process and testing process of wafers.

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

"Ah, the boss himself came. Wang Xingkui was pleasantly surprised, and immediately announced the dismissal of the meeting, and the four of them walked out of the conference room together, and soon saw Tang Fei's figure.

……..

Today's two shifts, the second shift is complete, thank you!

I got home this evening, and I started tomorrow, and I worked hard to code words, and tried to make three changes every day.
